So there are still no IME modules in current nightly builds?
It really would be useful to be able to tag files for an upcoming shoot. Any help would be greatly appreciated.

I am not able to compile this stuff myself so a link to the would be great.


Cheers,

Duplicate Questions / Re: Z-Depth
« on: June 20, 2014, 08:54:09 AM »
When i read the first post on this thread i actually laughed..

I too am a 3d artist who has been working in games and VFX for the last 15 years.
I have spent a great deal of time trying to perfect the process of adding DOF to a single beauty pass render in conjunction with a z depth pass. Even in CGI, This is not trivial to do well.

Now lets say even by some voodoo magic you are able to obtain a z depth image for each frame of video you shoot on your humble DSLR.

There are many caveats of doing DOF as a post process using plugins like frischluft LensCare.
The first major issue is that you cannot achieve an accurately natural background blur as your image will not have the information behind the foreground elements which occlude them.

ie. You can not blur what you can't see.
This creates an unnatural halo effect around objects where the information has to be interpolated by the blurring software.
The software has to 'make up' what it thinks is behind the subject.
This is why most 3d rendering is done in separate passes with the DOF applied to each layer separately. This is how professional compositors do it.

there are many other things to take into account to avoid ugly edge artefacting and create a natural looking image.
one of the key things you have overlooked is motion blur.

if you were to have any amount of motion blur in your "voodoo" z pass it would no longer serve as an accurate grey-scale depth map.
Yes, You could shoot your footage at a very high shutter speed and eliminate the motion blur in camera.. Then add that back in post using optical motion flow software..
but unless you are shooting at a high speed and have limited fast moving subjects, this is not a particularly reliable method either, Usually resulting in temporal and spatial warping artefactes.

Not to mention that you are already talking about shooting at a large aperture to eliminate DOF in the 'beauty pass'
Large aperture + high frame rate + High shutter speed = no damn light getting into the camera. you'll have to be shooting in broad daylight.

I am just going to suggest that rather than ask for features that encourage lazy post production reliant photography.. Pick your aperture and focus your camera correctly in the first place.. It's not that hard. and is't that part of the art of photography?..

But maybe there is hope for you yet!
Adobe has been experimenting with crazy new multi lens cameras that allow for re-focusing among other things, since 2007.
Check out this impressive demo -
Canon even filed a patent for a multi lens camera a few weeks ago -
http://www.canonrumors.com/2014/06/patent-multi-lens-multi-view-camera/

So perhaps this kind of thing is pretty close on the horizon.. I personally hope not ;)

Post-processing Workflow / Re: White strips when rendering in davinci
« on: June 19, 2014, 01:05:54 AM »
Yep, I've had that problem also. I've found it only happens if i was using a cracked version of the software ;)

I have a legitimate copy of the software but prefer not to have the ugly usb dongle sticking out the side of my macbook. or have to switch it between my macbook and workstation. Why don't they just use a damn serial key or licence managing software?..

Anyway, i ended up just using the free lite version which does 99 percent of what i want to use it for and it renders fine without the white strips.

Raw Video Postprocessing / Re: [WINDOWS] MLV to DNG Batch Converter
« on: February 06, 2014, 11:06:13 AM »
Nice job on the converter!

It's really nice to be able to spit .dngs and .wav files out through a nice GUI like this.
And the real time preview window for playback of .mlv files is great!
 
The only problems I'm having with it after using it for a couple of days are the output naming options. They are a bit limited and force me to end up with files that have way more information than I want to look at. If you could add check boxes to turn on and off all the prefix and numbering tags individually then people could customize the output however they desired.

I personally prefer to have a nice short - camera number_shot number_frame number

Currently the best I can get is this "MLV_A001_001_C00001_f000000.dng"

What I'd like is something more like this "A_001_0000.dng"

The only other thing is the progress bar, Which seem to only update at the end of converting each .mlv file? and calculates the percentage based on the number of clips done rather than the number of total frames?

I only tend to dump .dngs rather than create proxys so a percentage of total frames dumped would be more useful to see for an honest progress bar.

Oh one other thing, is it possible to get the audio to play in the preview player? doesn't seem to work for me at the moment.

Look forward to the future releases, Keep up the great work mate!

I think he's referring to the vertical noise pattern in underexposed shadows..? It has been discussed many times before.

My fix is not to shoot in pitch black darkness..

And exposing to the right will clean your image up allot in the shadows in general.

Modules Development / Re: Magic Lantern (RAW) Video format v2.0
« on: August 13, 2013, 12:29:53 AM »
so your raw is in E:\ ?


Yes. I have an E drive with a folder caller rawFiles in it and I have dumped all the recorded files from both cards into it along with the mlv_dump.exe.

Modules Development / Re: Magic Lantern (RAW) Video format v2.0
« on: August 12, 2013, 04:39:26 PM »
Not having much luck converting these.

This is what I'm getting back from the dos command.

E:\>rawFiles\mlv_dump.exe -o mlv.raw -r M13-0212.MLV
Operating mode:
 - Input MLV file: 'M13-0212.MLV'
 - Convert to legacy RAW
 - Output into 'mlv.raw'
Failed to open file 'M13-0212.MLV'

Any ideas why this would be failing to open?

MLV_DUMP

BUT you can't actually convert the .RAW converted from your .MLV with raw2dng for now.

Link dosn't work for me, no permission.

Anyone able to make MLV_Dump available please?

Cheers for that. yeah jumping the gun a bit, but I'll be prepped and ready for when we can convert them ;)

Looking very promising thanks g3gg0, excited to see where this ends up!

Any chance of posting a compiled version of the mlv_dump utility?

I Would love to have a go at testing this end to end but I'm not set up to compile.

Hardware and Accessories / Re: Android tablet as field monitor.
« on: July 30, 2013, 03:23:57 AM »
But then again it does work through USB at least to a certain extend, I am getting a Nexus 7 and am very curious about the functionality of the DSLR controller app...
I had a play with it using last years Nexus 7 on my 5dmk3 and it worked surprisingly well!

It works really well for finding focus as the picture looks better than what i get on my 5 inch Ikan field monitor. even though it only has the resolution of the lcd liveview which i believe is 800x480, it looks much sharper than the 1080i that i get though the hdmi on the ikan. maybe this will change if we ever get a magic lantern port to firmware 1.2 on the 5dmk3 with clean 1080p

The remote operation through the touch screen is a nice bonus but you won't get the magic lantern menus, you'll still have to do this on the camera lcd.

I like that it allows you to use the tablet as an external field monitor while leaving the camera lcd fully operational for monitoring so that you can have two points of monitoring.

It also means you don't have to wait for the horribly slow switching between liveview and hdmi output whenever you want to use the camera or magic lantern menus!

The only real downsides i can see in my testing,

The image lags slightly.. Hopefully this improves with the newever nexus tablet and is not hitting the limit of usb2. It's totally useable as is though.

It drastically reduces the record speed of the camera in raw recording mode. resolutions i was able to record continuoisly in previously were limited to 200-300 frames.. Not sure if there is anything that can be done about this on the magic lantern end?..
I asked the developer of DSLR controller if he would be able to do anything to reduce the overhead, He said that it would have to happen on the ML side as he is only using the standard canon remote interface.

The battery will probably only last 3-5 hours. But i imagine you could hook this up to a battery system with the right adapter cable.

I found the start/stop record button to be a bit flakey so i just ended up using the hardware button on the camera.

Other than that the only issue i can see with it is figuring out how to mount a nexus nicely to the camera. I've seen one solution using a car dashboard mount but it looked a bit goofy..

With a bit more work this thing could be really awesome as a low cost alternative to expensive field monitors. withe the added ability to remote control on cranes etc!

It even has a selection of anamorphic de-squeeze options!

Raw Video / Re: cropmarks for RAW shooting
« on: July 15, 2013, 12:22:03 PM »
Yeah i used photoshop but you should be able to modify the cropmarks .bmps with almost any image editing package.

Here's a link to the one i've made

https://docs.google.com/file/d/0B7QbtsM_uQoJS3JjSHhfMjNyUTQ/edit?usp=sharing

The centre rectangle represents the recorded 1728 x 1288 cropped from the middle of the sensor. i shoot anamorphic so its a 4:3 aspect ratio. Change it to what ever size you want to shoot in crop mode and it should serve as a pretty good guide for framing your shots.. albeit a tiny thumbnail size..

This is the best way i can think to do it unless i'm missing a preview function for crop mode? maybe others have ideas!?

btw. you can turn it on or off (at least on the 5dmk3) by cycling through the info display button to clear all the overlays.

Raw Video / Re: cropmarks for RAW shooting
« on: July 13, 2013, 05:18:45 PM »
for anything shot full frame, The liveview usually displays a white recangle showing the recorded area, Unless you dissable overlays in the ML display menu that is.

For crop/zoom mode shooting I've created a custom cropmarks .bmp which masks out the center 4:3 area in the live view so that i can frame my shots prior to recording. This is only really usefull for locked off shots as you still only see the magnified crop on screen durring recording.

You can easily do this for any custom crop resolution you might be using. I Just made an indexed colour image like the existing crops in the magic lantern data, With an image size of 5760 × 3840 (full resolution of the 5dmk3 sensor) then created a rectangle the pixel dimensions of my desired cropmode record resolution and filled it with the transparent colour. Resize it to 720x480 and save as a new bmp in the ML cropmks folder.

Raw Video / Re: How to turn off "Frame Recording Overlay"?
« on: July 11, 2013, 12:52:37 PM »
If you're asking how to clear all the info overlays off of the screen while recording then I've achieved this by going into the magic lantern menus 'Display' tab and setting 'clear overlays' to 'while recording' or 'always'. I hope this is helpfull!

Raw Video / Re: Turn your RAW footage into LOG
« on: July 04, 2013, 02:29:57 PM »
If your goal is to color grade, why would you need your footage to be in LOG when you've got it in RAW?

There is more information in raw than there is in log... to me this seems like it would be just an extra step when you can just color grade your original raw files in resolve when you've completed your edit.  :-/

Like i said, Resolves debayer dosn't seem to do as nice a job as ACR. unless i'm missing some magic setting somewhere??.. I Wouldn't be surprised as Resolves interface is an alien nightmare to me..
Is it just me or is does any one else find it to be hugely unintuitve and awkward? it seems really obviously mac centric lacking in simple things like a standard windows minimize button or the ability to choose which of my monitors i want to run it on.. Yeah, as hard as i've tried i really don't like it much..

Anyway, Ideally i would go straight to cineform raw through goPro studio and then create and apply luts as active meta independent of the edit, seems the most flexible workflow requiring least render/re-encoding should i want to tweak any of my looks along the way.
Why would i want to be limited to completing an edit before grading anyway?

Unfortunately the realtime debayer of cineform raw seems to suffer simillar edge artefacts as Resolve so the best option for me as far as i can see is
(ACR - cineform444 - grade in finess and export lut - apply lut in cineform studio or first light)

So as i'm stepping out of raw space after ACR it makes sense to me that i would want to have a log image to grade in..?

like allot of people here i'm still trying to figgure this stuff out so i'm keen to hear other sugestions!

Raw Video / Re: Turn your RAW footage into LOG
« on: July 04, 2013, 01:00:51 PM »
Thanks aaphotog! Been searching for something like this and I will give it a try.

Though i'm wondering weather this step would make more sense to do at the raw - demosaic stage using the curves in ACR?

anyone tried this and have a good ACR preset to share?

seems like you would retain more of the latitude of the original raw doing it straight out of ACR..? The BMC log profile in resolve does a nice job of this when applied to interpretation of the raw cDNGs but i'm not a huge fan of the resolve route for grading/transcoding as it makes a bit of a meal of the debayer resulting in nasty chroma edge artefacts.

Still looking for the best way to ingest and precess this beautifull raw footage in a way that suits my workflow but is seems like there is always a trade off in speed / ease / quality..

Is it currently possible to record h.264 .movs simultaneously to sd for use as proxies in editing?

I'd love to try using the RAW feature for a short film shoot next weekend but the quick turnaround won't really allow for processing the dngs before editing..

Hey ML team,

Congrats and great work on ML over the past week! I have been following very closely and using the nightly builds since they were first made available. The results have been amazing and i can't believe how much progress has been made in such a short time. It's starting to look like a real usable feature!

There were some earlier mentions on this thread of being able to record raw video while simultaneously recording the standard h.264 stream to the sd or cf card. if this is the case then how would i go about enabling it. Without having to figure out how to turn on the necessarily code switches and compile it myself..

I am generally recording a solid 24 or 25p @ 1920x840 to a delkin x1000 16GB card on a 5d mk 3!

Cheers guys! Keep up the great work!
