Movie



Functions specific to movie mode. 



Bit Rate

Controls H.264 bitrate used for video recording.

Submenu options:

Mode
  • CBR is constant bitrate. You specify a factor for multiplying default video bitrate, between 0.1x and 3.0x. CBR 1.0x is the firmware default setting. CBR actually works by adjusting QScale on the fly; the instant value is displayed near the recording dot.
  • QScale is constant quality, variable bitrate (VBR). Available values are -16 to +16. Lower numbers mean higher bitrates, but it's not as stable as CBR and increasing the bitrate may cause recording to stop. You need a fast card. In QScale mode, bitrate is completely out of control (don't use it!).
  • Firmware default completely disables bitrate control.
CBR factor 0.1x to 3.0x.

QScale -16 to 16.

Bitrate Info ON or OFF.

BuffWarnLevel 30 to 100.

In CBR mode, QScale will not go outside [-16…+16]. When QScale reaches the extreme values (-16 or +16), bitrate will be different than your CBR setting. Watch the bitrate indicators. This is not a bug, please do not report it. You can push the bitrate higher if you record without sound, then use Audio RemoteShot to sync the video with an external audio track. You can't change this setting during recording. If buffer usage gets too high, ML will pause all CPU-intensive graphics. Change the BuffWarnLevel setting to customize this.



REC key

This option enables you to start/stop movie recording by half-pressing the shutter button.

Submenu options:

Require long press

Allowed actions

With this, you can use a wired remote to start/stop recording.



Gradual Expo.

Submenu options:

1EV / 8 frames
1EV / 16 frames
1EV / 32 frames
1EV / 64 frames
1EV / 128 frames
1EV / 256 frames
1EV / 512 frames




FPS override

This setting alters FPS for all video modes.

Submenu options:

Desired FPS 0.150 fps to 65 fps depending on your model capabilities. If the desired value is not possible, ML will choose the closest safe option (see 'Actual FPS' below).

Optimize for Presets that will suit different situations:
  • Low light - use this option for recording timelapse with shutter speed set to 1/fps (360 degrees); at high FPS values, you may be able to use other shutter speed values.
  • Exact FPS - try to achieve an exact FPS value, such as 24.000 or 30.000 or 12.500. If more exact solutions are found, ML will choose the one with lowest jello effect.
  • High FPS - changes FPS without altering shutter speed and allows a slight overcranking (60D, 600D).
  • LowJello - 180d try to minimize the jello effect caused by rolling shutter, while allowing you to expose at 180 degrees (0.5/fps) if possible.
  • High Jello: maximize the jello effect and enable fast shutter speeds. You can use this mode for recording slit-scan frames (distorted images like these, which use the extreme jello effect in creative ways).

Shutter range displays the available shutter speed range with current settings. When you use FPS override, Canon menu will still display 1/30 to 1/4000, but the actual shutter speed will be found on ML displays. You can alter shutter speed range by changing the ratio between the two timer values - decreasing timer B will result in faster shutter speeds available.

FPS Timer A FPS is changed by altering two timer values. Increasing either of these values results in lower FPS, faster shutter speed and alters rolling shutter. Only undercranking works well.  Timer A gets you in the ballpark and ML will re-adjust timer B to match your FPS choice.

FPS Timer B ML will not re-adjust timer A, so this option will let you fine-tune the exact FPS value.

Main Clock displays the crystal oscillator frequency of the FPS circuit driver (read-only, depends on your camera).

Actual FPS this displays the current FPS, computed as TG_FREQ / timerA / timerB (read-only).

Constant expo

Sync w.Shutter

FPS ramping

Ramp duration

This function will not change the frame rate from the video header; the video will playback at the setting from Canon menu. Set FPS to a very low value like 3fps to record a timelapse. This feature also works in photo mode, making LiveView usable in dark environments. Combine it with display gain. To get 180-degree shutter speed at very low FPS, simply discard half of the frames in post. If 0.2 FPS is not enough, use Frame Merger (a VirtualDub plugin). Exact frame rate may be rounded to be an exact multiple of PAL/NTSC frame rates.
  • PAL modes: 25p/50p. Rounded frame rates: 33.333fps, 12.5fps, 11.111fps and so on.
  • NTSC modes: 30p/60p/24p. Rounded frame rates: 29.97fps, 23.976fps, 11.988fps and so on. For fine-tuning and calibrating custom frame rates, use EOSTimerGen.


HDR video

This feature allows you to shoot a high dynamic range video by alternating ISO every other frame.

Submenu options:

ISO A

ISO B

Select the two ISO values from the submenu. Possible postprocessing workflows:
  • Interframe script: user-friendly version and bare-bone version
  • GingerHDR (plugin for Adobe After Effects and Premiere)
  • Magic Lantern HDR Compose generator for FCP X
  • HDR Glogger Web Service
  • etc (please help me filling the list!)
Discussion thread, postprocessing workflow, FAQ...



Vignetting

In camera vignetting.

Submenu options:

Mid-range correction Correction applied between the central areas and the corners.

Corner correction Stronger bias towards corners.

Extreme corner correction Heavy correction in the corners.

Minus values increase the vignette.



Image Finetuning

Settings for fine control of your image.

Submenu options:

Raw video has come a long way in a year 2014: NEW Current Raw Capabilities.



Movie Tweaks

Submenu options:

Time indicator When recording a movie, ML will display a small time counter in the upper right corner, which can be:
  • Elapsed: duration of the current clip
  • Remain.Card: estimated amount of recording time remaining on the card.
  • Remain.4GB: estimated amount of recording time until reaching 4GB (or until filling the card, whichever comes first).
Unlike Canon's timer which assumes constant bitrate, ML timer assumes variable bitrate and works even if QScale is enabled. However, due to variations in bitrate, the estimated value will fluctuate a lot, and this is normal.

Movie Logging If this setting is ON, Magic Lantern will write out a metadata file for the each movie to MVI_1234.LOG (numbered after the movie). The log file contains lens and exposure info, as well as a timestamp every time any of the parameters is changed during recording. Log files are placed in the same folder as the movies: DCIM/100CANON/, 101CANON etc. Tip: you can rename LOG files to CSV and import them in MS Excel.

Movie Restart While this setting is on, movie recording will restart automatically, unless you stop it. There will be a few seconds skipped during restarting.

REC/STBY notify Custom notifications for recording or standby:
  • Red Crossout highly recommended if you forget to press record
  • Message it shows STBY or REC
  • Beeps it will beep when recording starts or stops
  • Blue LED obvious if your camera has it
Force LiveView bypass the dialog saying Press LV button to activate movie shooting.
  • Always: force LiveView even if you use an unchipped lens, or no lens at all. Be careful, you may get dust on the sensor while changing lenses.
  • Start & CPU lenses: it will force LiveView at startup, regardless of the lens used. After this, it will only bypass the dialog when a chipped lens is attached (i.e. it will enter LiveView as soon as you attach a chipped lens).

Shutter Lock This option locks the shutter value in movie mode (you will be able to change it only from ML menu).



Movie Record (50D)

Submenu options:

Enable movie recording on 50D (1920×1080, 30fps, without sound). To start recording, go to LiveView (P/Tv/Av/M) and press SET. WARNING: Canon 50D was NOT designed to record movies. Keep in mind: This feature was not thoroughly tested by Canon and may be unstable (even if you record without ML). Always disable movie recording when you don't use it. Battery will drain quickly when recording; also, the camera may overheat.

Limitations: The camera will not record sound. You can use an external recorder (for example, Zoom H1, H2 or H4n) and sync the sound in post with a clapperboard. You can't play back movies in the camera. This setting remains active even if you start the camera with standard firmware (until you clear your settings).



Shutter Button (50D)

Submenu options:

Block during REC blocks the shutter and related (AF, *) buttons while recording. In 50D, taking pictures while recording would result in ERR99; with this option, you can avoid taking pictures while recording by mistake. Side effect: this will disable image stabilization during recording.

Hold during REC (IS) ML will keep the shutter button pressed half-way during recording, which will enable image stabilization (IS). Side effect: you need to press the shutter button half way to turn IS off before the camera will let you stop recording.



Exposure Lock (50D)

Submenu options:

Locks the exposure in movie mode. You can also use the * button (you don't have to hold it pressed).

Overlay



Graphics overlays that can be used in LiveView or in image review mode: histogram, zebras, cropmarks, spotmeter, focus peaking, false color…



Global Draw

Choose when to enable Magic Lantern overlay graphics such as zebras, cropmarks, histograms, audio meters and other ML shooting info.

Submenu options:

OFF

Liveview

QuickReview (photo mode outside LiveView)

ON, all modes

If you used display presets, press Q on this item to switch the presets while you are in ML menu.



Zebras

Enable/disable zebra stripes, which indicate overexposed or underexposed areas.

Submenu options:

Color Space:
  • Luma: zebras are computed from Y channel only.
  • RGB: check overexposure for each RGB channel. Clipped channels are displayed in the opposite color (i.e. clipped red shown as cyan, underexposed as white and so on).

Underexposure - JPG only.  Set the RGB point where underexposure zebras are displayed.

Overexposure - JPG only.  Set the RGB point where overexposure zebras are displayed.

When recording - Show or hide zebras while recording.

Use RAW zebras - Enable raw based zebras.  This uses the raw sensor data for zebras.

  • Off - Disable raw zebras.
  • Always - Always show raw zebras, including in live view mode.
  • Photo only - Only show raw zebras in image review.

You may adjust thresholds for underexposure and overexposure, or you can disable zebras while recording. Note: when using the Technicolor CineStyle picture style, luma will have values between 16 and 255; therefore, you will have to set the underexposure threshold to 16 or greater.



Focus Peak

Focus assist function.

Submenu options:

Filter bias:

Image buffer:

Threshold: how many pixels are considered in focus (percentage).

Color: either fixed color, or a color coding according to focus intensity.

Grayscale image: if enabled, LiveView will displayed as grayscale, but still recorded as color.

High-contrast lines will be marked by blinking dots showing which part of the image is in focus. To see how it works, check this article from Luminous Landscape.



Magic Zoom

Displays a zoom box for focus assist. Can be used while recording.

Submenu options:

Trigger mode
  • FocusR+HalfS: triggered by turning the focus ring, or by pressing shutter halfway.
  • Focus+ZREC: triggered by turning the focus ring, or by pressing Zoom In while recording.
  • Zoom In (*): triggered by Zoom In button (overrides Canon's default zoom modes). To bypass magic zoom, press both zoom buttons at the same time or cover the LCD sensor.
  • Always On: no trigger key needed. You can use both Canon's 5x/10x zoom and Magic Zoom.

Size

Position

Magnification

Focus confirm When ML believes you have achieved perfect focus, Magic Zoom will display a focus confirmation:
  • Green Bars
  • Split Screen: when the image is out of focus, the zoom box looks like a split focusing screen from old film cameras.
  • Split Screen with ZeroCross: will reverse the split direction whenever you achieve perfect focus.

Zebras, focus peaking and false color are disabled automatically when the zoom overlay is active. Focus triggering only works with lenses that report Focus distance, or when you use follow focus / rack focus. In some modes, half-pressing the shutter may temporarily hide the zoom overlay. Original implementation: Magic Circles by AJ.



Cropmarks

Cropmarks or custom grids for framing and composition.

Submenu options:

Bitmap (1/9)

Show in photo mode

Show in PLAY mode

If you use custom cropmarks, place them in ML/CROPMKS folder on your SD card and give them short 8.3 names. You can place at most 9 cropmarks on the card. Get more cropmarks from the ML cropmark repository or draw your own (see Cropmarks).



Ghost image

Shows a transparent overlay which can be created from any image in Play mode.

Submenu options:

Auto-update

To select the image, go to Play mode and press the LiveView button. Move the ghost image in LiveView with arrow keys; center or hide it with SET or joystick press.



Defishing

Preview the rectified (defished) image from Samyang 8mm fisheye lens, using rectilinear projection.

Submenu options:

This feature works best in photo mode (outside LiveView). Defishing uses a pre-computed look-up table (LUT). It is possible to create LUT files for any other lens or projection by defishing vram/xy.png with your favorite defishing software, and then running vram/defish-lut.m to get the LUT file. All the required files are found in the ML source tree. Project files (*.PTO) for nona (hugin) are provided for both rectilinear and Panini projections.



Spotmeter

Measure brightness from a small spot in the frame.

Submenu options:

Spotmeter Unit
  • Percent - 0 to 100%.
  • 0..255 - RGB levels.
  • RGB (HTML)- Displays HTML-like color codes.
  • RAW (EV) - Exposure level from sensor saturation using raw sensor data.

Spot Position
  • Focus box - Spot meter linked to the focus box.
  • Center - Spot meter linked to the center of image.



False color

This is a tool for evaluating the exposure.

Submenu options:

Marshall

SmallHD

50-72

67-72

Banding detection

GreenScreen

It shows different luma (Y) levels using a color map. You may configure a display preset with False Color and toggle it with a single button press. You may also use false colors to highlight 50% and 70% brightness levels, or to reveal color banding, or to check for uniform green screen lighting.



Histogram

This exposure tool will show the distribution of image brightness levels in a histogram.

Submenu options:

Color space
  • Luma - Overall brightness
  • RGB - Individual Red, Green, and Blue channels

Scaling
  • Logarithmic
  • Linear

Clip warning - Display a warning is the histogram with clipping.  This will display a warning for each color channel, when that channel is being overexposed.  The numbers represent the percentage of pixels being clipped.

Use RAW histogram
  • OFF - Disable raw based histogram and use JPG based histogram.
  • Full Histogram - Use the full histogram.
  • Simplified Histobar - Only use the simplified histobar in liveview.

RAW EV indicator
  • OFF - Don't not use the indicator.
  • Dynamic Range - Display the dynamic range at current ISO, from noise stdev.
  • ETTR hint - Show how many stops you can push the exposure to the right.



Waveform

Expo



Adjusting the exposure parameters. Most of these settings only work in Manual (photo and video), and some of them work in P, Av and Tv too.



WhiteBalance

White balance controls.

Submenu options:

White Balance: Rated in Kelvin, manually adjust from 1500 to 15000K.

WBShift G/M: Green-Magenta white balance shift. Useful for fluorescent lighting.

WBShift B/A: Blue-Amber white balance shift. 1 unit = 5 mireks on Kelvin axis, according to this post.

Custom RGB multipliers: Fine-tune custom white balance.

Black level: This parameter is applied on RAW data, before applying white balance. Adjust it if you have problems with green or magenta shadows.

Auto adjust Kelvin + G/M: In LiveView, ML will compute the white balance for the current scene, using the center (200×200 pixels rectangle) as reference gray.

The preferred method is manual White Balance, but when shooting raw video this is more of evaluative tool as you have control of your WB later. Best practice is to have a reference colour at the beginning of each shot, with neutral grey being preferred to white as whites can blow out and give you a false reading.



ISO

Advanced ISO control.

Submenu options:

Equivalent ISO: Overall ISO rating

Canon analog ISO: 100 to 3200 ISO at which the sensor is driven

Canon digital ISO: Digital ISO is the process of pulling or pushing your analog ISO to affect detail.

ML digital ISO (DIGIC): -2 to +7 EV Preferred to the Canon implementation, in movie mode negative values will reduce noise, but may cause color issues in highlights. This feature
enables ISO 50, ISO 51200 and many other intermediate or astronomical ISOs.

Display Gain (night vision): In photo mode, for previewing night scenes.

Highlight Tone Priority: Increases dynamic range by 1 stop in movie mode. Use with negative ML digital ISO.

ISO selection: Canon ISOs or ML ISOs. Only used in movie mode.

Color coding:
  • orange = Standard Canon ISO with good noise or dynamic range characteristics.
  • green = ISO with negative digital gain applied via DIGIC obtained by setting ML digital ISO to a negative value. These can have lower noise or better highlight rolloff than their Canon counterparts.
  • red = ISO with positive digital gain, avoid these values.



Shutter

Fine-tune shutter speed.

Submenu options:

1/31 - 1/3900 Without Expo.Override enabled

1/24 - 1/7900 With Expo.Override enabled

In photo mode, Magic Lantern displays shutter values rounded to 2 significant digits, so 1/48 may be displayed by ML as 1/50. This is not a bug. In movie mode, shutter values are displayed with 3 decimal places for example, in PAL mode, Canon uses 1/33.333 to avoid flicker. To use shutter speeds normally not available in Canon firmware like 1/25 or 1/8000 in movie mode, enable Expo.Override. The shutter can be locked (perfect for video) in the Movie Tweaks section of the Movie menu, meaning you have to go into the ML menus to change it.



Aperture

Adjust aperture.

Submenu options:

Requiring a chipped lens, when Expo.Override is enabled, you can adjust in 1/8 stop increments.



PictureStyle

Change picture style or adjust its parameters. 

Submenu options:

Picture Style

Sharpness

Contrast

Saturation

Color Tone

REC-PicStyle

You can use a different picture style when recording (toggled automagically). May be useful with flat picture styles. Raw video makes no use of this feature.



Auto ETTR

Automatically expose to the right.

Submenu options:

Trigger mode Always ON, Auto Snap, Press SET & HalfS DblClick. Method for executing Auto ETTR.

Slowest shutter 32" to 1/4000. Set your lowest speed.

Exposure target -0.5, -1, -2, -3 & -4EV. -0.5 or -1 recommended.

Highlight ignore 0 to 50%. Percentage of bright pixels allowed above target level.  Use this to allow spec(ta)cular highlights to be clipped.

Allow clipping OFF, Green channel & Any channel. Choose which channels to be clipped.

Midtone SNR limit 0 to 8EV. Stop underexposing when at least 50% of the image gets noisier than selected SNR.

Shadow SNR limit 0 to 6EV. Stop underexposing when at least 5% of the image gets noisier than selected SNR.

Link to Canon shutter Hack to adjust slowest shutter from main dial.

Link to Dual ISO Let ETTR change Dual ISO settings so you get the SNR values in mids & shadows.  It will disable dual ISO if not needed.

Show metered areas Show where the white point and SNR levels are metered (what exactly is considered highlight, midtone and shadow).

Show debug info For nerds.

See ettr.mo in the modules post.



Exp.Lock

Locks different exposure controls.

Submenu options:

Tv

Av

ISO



Exp.Presets

Toggles for exposure presets.

Submenu options:

OFF

Press SET

Press INFO



Dual ISO

Capture using 2 different ISOs for better detail in certain ranges.

Submenu options:

Recovery ISO

Dynamic range gained

Midtone overlapping

Alternate frames only

Custom file prefix

See dual_iso.mo in the modules post.



Exp.Override

This mode bypasses Canon exposure limitations for ISO, Tv & Av.

Submenu options:

OFF: Canon default exposure mode.

ON: ML overrides exposure values (change them from Expo menu).

Auto: ML enables it only when needed.
  • Manual video exposure controls - 500D/50D/1100D.
  • Non standard shutter speed, aperture or ISO - 550D/60D/600D/5D2.
  • Fix LiveView underexposure bug with manual lens - 60D.
  • 1/25s in movie mode (24p/25p) → 1/3 stops better in low light.
  • 1/8000s in movie mode, useful for slow motion.
  • ISO 12800 is allowed in movie mode on 60D and 600D.
  • Full-time DOF preview in photo mode, without blocking certain keys.
In photo mode, anything slower than 1/25 seconds will be underexposed in LiveView. Low framerates in FPS override have fixed shutterspeeds. To compensate exposure adjust aperture and ISO. In daytime, this is tough as even at ISO 100 it would still be bright even if lens is closed down, I recommend a VARI-ND.



LV Display

Selects or displays LiveView display type.

Submenu options:

Photo display, no exposure simulation (for framing and for flash photography)

Photo display, with exposure simulation

Movie display



Auto exposure

Automatic control of your exposure during a take.

Submenu options:

See auto_expo.mo in the modules post.

Audio



Manual audio controls. This menu is not available on Canon 600D / T3i. The 600D/T3i already has manual audio control, but right now it's not possible to change audio settings from Magic Lantern. You can only use audio meters during recording. 5D2 and 600D have more audio controls than any others, with 5D3 having very little.



Analog Gain

Gain applied to both inputs in the analog domain.

Submenu options:

0-32 dB

Analog does a great job of boosting the signal while retaining a low noise floor and hence, dynamic range. If you use an external preamp, set this parameter as low as possible otherwise, set it as high as possible without clipping (audio meters should be green).



DigitalGain

In-camera digital gain.

Submenu options:

Left Digital Gain 0 to 36 dB in 6 dB increments

Right Digital Gain 0 to 36 dB in 6 dB increments

AGC ON or OFF

Applying digital gain in-camera is not recommended as any nonzero value reduces audio quality and you can achieve the same effect with more control in post, but it can serve as an evaluative tool on set. You can apply digital gain in 6dB increments to the left and right channel independently. AGC is auto mode and is applied only in digital domain. It overrides digital gains, but you can still adjust analog gain.



Input source

Mic configurations.

Submenu options:

internal mic your camera's internal mic

L:int R:ext

external stereo

L:int R:balanced (internal mic on Left, external mic on Right from both external pins as balanced audio)

Auto int/ext camera detects if a mic is plugged in. Int is dual mono, ext is stereo.

Balanced audio allows for very long cable runs without interference. Usually balanced mics have three pin XLR connectors and it is very easy to put together an XLR to Canon mic input cable. Balanced allows us to use such pro mics with our little Canons and this is a very welcome surprise for audio guys. You can feed an external audio source into the camera giving you the option of using higher quality mics, although this is not straight forward.



Wind Filter

Digital high-pass filter.

Submenu options:

On or Off

Canon's audio controls have no effect, they are completely overriden by ML and the wind filter has been known to mute external mics, so if you're having that problem on an earlier build turn it off. To use or not? Also see AK4646 datasheet p.34.



Mic Power

Power for mics.

Submenu options:

ON input impedance is 2 kOhm.

OFF input impedance is 30 kOhm.

Required for internal mic and certain types of external mics, but it reduces input impedance. This setting is always ON when input source is either internal mic or L:int R:ext. See AK4646 datasheet p.31. and the Mic power control thread. Results of audio tests with ML and Canon 550D, T2i.



Headphone Monitoring

Audio monitoring with headphones, using the A/V cable.

Submenu options:

On or Off

To use audio monitoring, you need a special cable: your Canon A/V cable with a RCA - 3.5mm jack adapter a dedicated cable from Sescom or you may solder it yourself (you will have to cut your A/V cable). Mobile phone cables will not work; even if the connector looks similar, it's not identical. You must use the original cable which came with your camera. For details, see Audio monitoring HOWTO on Vimeo group. Disable this setting if you are using a SD monitor. This feature is not available on 600D/T3i.



Output volume

Digital output gain for audio monitoring.

Submenu options:

0 dB
2 dB
4 dB
6 dB


It does not have any effect on the internal camera speaker. For best results, you should a pair of low impedance headphones, for example Audio Technica ATH-M50 (38 ohms). With high-impedance headphones, you may have to use a headphone amplifier like FiiO E5.



Audio Meters

Display the input audio level.

Submenu options:

From -40dB to 0dB, meters become yellow at -12 dB and red at -3 dB. Audio meters are only displayed in movie mode.



Speaker Volume

In-camera speaker.

Submenu options:

1 to 5



Beep, test tones

Customise camera sounds.

Submenu options:

Enable Beeps

Tone Waveform

Tone Frequency

Play test tone

Test beep sound



MLV Sound

RAW video (MLV) now comes with audio!

Submenu options:

Sampling rate 8 - 48kHz the basic quality of your audio, the higher the better.

Trace output ON or OFF

When MLV Sound is ON, a separate WAV file is generated at the framerate determined by your FPS setting in Canon Menu. When FPS Override is used, only the framerate of raw video is affected, the WAV file will remain either 24fps or 30fps depending on the FPS setting in canon menu. It is not possible to playback mlv sound in-camera.

This menu is only available when the mlv_snd module is loaded and active.  See Modules

Let's restore ML help together!




I want to start a thread where we collect all the information in one place. I've mapped out the menu & submenu options of the latest nightly (30/03/14) and pretty much all of the accompanying  documentation could do with an update - Please feel free to add any information, and your post can be merged into the guide. I've also added a few other topics that deal with post production which I will edit with more information and links as I go along. I'm far from an authority on any of this though and I'm hoping that the rest of you will contribute information and correct any of my mistakes.

In AE when I import a dng sequence it comes in at 30 FPS regardless of what it was actually shot at.

There's a setting in the import section of AE preferences - Sequence footage - the fps you choose there is your default.

I have the 5d2 version and I haven't had to think about aliasing at all since I put it in.

I think the 50D tops out at 70MB/s. You have to remember that all the posts you see on here telling you what speed someone got is based on their precise settings. Things like fps, resolution, ratio, global draw and optimizations have massive effects on record time. I'd keep both cards as you will need them anyway, but do your own tests to compare each one and post the results.

I must admit my knowledge of benchmark is limited to a couple of runs. I still think Disease should poke around in the settings, although this is the second report I've seen today about dud Komputerbay cards from Ebay.

What mode did you do your benchmarks in?

My Komputer Bay Benchmarks
« Reply #53 on: June 14, 2013, 07:01:50 PM »

Your 128GB results are invalid as you ran the benchmark in playback mode. Run it in movie mode with live view enabled to get an accurate impression of how it will perform during raw recording. You will find it is slow - around 70MB/s, pretty much all the 128GB KomputerBay cards are. The 64GB cards are fastest."


I'm just guessing here, but you said yourself that you are overwhelmed by the amount of options and I know I was at first, so I'd advise you hold off on returning until you are sure you haven't overlooked something. What resolution / ratio are you recording at? You need to go through the ML settings and switch off everything that you are unsure of and trawl through the site for the relevant info.

« on: August 04, 2013, 07:50:43 PM »
I'd like to see all these issues ironed out, but a lot of the problems you mention didn't exist till a few months ago, Dave. As for handing off footage to clients, that's what you are getting paid for in all fairness. You could always shoot in h.264 and hand that off? From watching an interview with Trammell Hudson, ML's original goal was making the dslr more suited to independent film and video. It's legacy will hopefully be putting professional level tools in the hands of more film makers. If Stanley Kubrick told you to run wild with a camera, ML taught you how to tame it.

You would have to check the 50D threads for specific info about camera and card speed, but the advertised 150 MBs is theoretical and dependent on the device it is used in. I don't think the 50D is anywhere near capable of that, so benchmark your card with your computer via USB 3 if you can.

There are certain camera settings that make the raw module more stable such as disabling raw photos and adjusting the display in the Canon menu. Also in the raw module of ML (on the builds I use) there is a 'small hacks' setting and 'card warm up'. There are probably more I have forgotten, but it's really a case of you trying them out for yourself and seeing what works for you.

Have you contacted Komputerbay about this? I've had 2 of those cards since June and no problems thus far, although I got mine from the Kompbay shop on Amazon.

General Development / Streamlined builds?
« on: August 04, 2013, 02:48:58 PM »
Is it possible to and is there any value in removing features that are not used? I have my set up saved to the config file of course, but would there be any gains from completely removing what I have hidden from the builds? I'm not looking for any of the developers to do this, just if it is worth me investigating for myself.

General Help Q&A / Re: 1.2.1 build likely any time soon?
« on: August 04, 2013, 02:35:08 PM »
I doubt we will see a 1.2.1 version before raw, dual ISO, .mlv and the other recent developments have been exhausted. The existing features of ML seem to outweigh the need for 1.2.1 for most of the other 5d3 guys and I know from my own experience that I very rarely have to go into the Canon menu to do anything now.

Have you benchmarked your card and read up about optimizing your camera for raw?

I saw that and will give it a whirl tomorrow. Does it show thumbnails for folders (not clips) when importing to Resolve? That's what I originally got the bulk rename utility for, but it comes in handy for renaming sets of files without the (1) (10) (2) bug.

@Ted http://www.bulkrenameutility.co.uk/Main_Intro.php you can rename a bunch of folders quickly with this.

The new Nexus 7 looks like being perfect for monitoring. In terms of reboot time, what happens when you disconnect the devices? Is it feasible to unplug the Nexus just before hitting record and then plug back in to set up your next take?

What kind of grades?

Your video has a commercial feel, more bright than colourful and you could describe it as 'uplifting'. I suppose switching that around and it being more colourful than bright could be a place to start. This is in no way a criticism.

This is with only the .mo files placed in the module folder of a.d's 728e571a1276. Can't see how I'm doing things any different than usual, but I'll see if there is something I've overlooked.
