Hey guys,

Just installed this build to my Canon 5D Mk 3 and it's working pretty well. I'm using the dual shooting mode with my SD and CF card and can do continuous 3.3K RAW in 10 bit, which is awesome.
HOWEVER.
In every single one of my clips, there is this weird pink aliasing (for want of a better word) on the highlights. Literally every single clip I record that is the slightest overexposed, the pink lines appears.
Even on text on a screen, it appears.
I've trolled through the forums and looked at countless posts, but to no avail. I'm using the latest 2021 Feb build, so I'm not out of date. I've got Global Draw turned off as well.
I haven't enabled any dual iso stuff, or anything to do with any custom overlays.
Help me Obi-Wan MagicLanternForums-obi, you're my only hope!

EDIT:
I've been using the EV function and have been exposing by about +1 EV to get proper exposure in the RAW files. Pink areas everywhere.

Hi,caylemweeks
MLVApp-profiles-cyan highlight fix
Try this option.

masc · « **Reply #902 on:** March 13, 2021, 10:04:28 AM »

@caylemweeks: sounds like you clipped the green channels. Try highlight reconstruction in parallel to RAW white level adjustments in MLVApp. In Resolve there is also a highlight reconstruction feature.
And for the future: use zebras and ETTR in camera and try to not overexpose!

Hello all. I just made the large jump from a ML build from 2016 to the most recent one crop_rec_4k_mlv_snd_isogain_1x3_presets_2021Feb28.5D3123

Looks like things have changed quite a bit.

On the 2016 build, I would use Dual ISO in addition to crop mode for a resolution of 2560 x 1090
I had card spanning and was able to shoot continuously.
Monitoring was a challenge since Live View was gray, low quality, and not real time

Will the latest build help me solve some of these challenges?
Can I shoot Dual ISO, 4k continuous? Is card spanning deprecated and no longer available now? How do I get continuous shooting? (overclock module hasn't seemed to help. Maybe I'm doing something wrong)
Can I get a good monitoring situation? Live view and perfect framing of scene being shot?
How high up can I go in resolution these days and still use Dual ISO, without any bottlenecking of the camera or cards?

Thanks much all

First of all this magic lantern build has no crop anymore. With anamorphic on you do still get the view in black and white and no real time. But if you would change to the normal Canon view. You get a view croped and squeeze. There for it is in real time and sharp. With 14 bit lossless you don't have to use card spanning anymore. It works stable will my camera setup. Although I don't use duel iso since I noticed that it is a little less sharp.

Thanks. Attached are screenshots of my settings. Any recommendations?

Also, looks like the liveview is 5x and doesnt let me frame correctly however. Anyway to get a more accurate live view?

Thanks again

Danne · « **Reply #906 on:** March 15, 2021, 06:20:22 AM »

Nothing changed with preview capabilities. If not real time uncropped use framing for correct preview.
A few refined presets added like the anamorphic modes(Also called 1x3 binning).
Card spanning works. Sd uhs patching not very reliable. If using that see to it to test out a valid, good working card. Info on this can be found in varous posts and threads.
Other than that, a lot of tweaks and a few bug fixes.

I recommend you go through this thread as it progressively shows what´s been added into this build. Most questions have been answered if not all.

kidfob · « **Reply #907 on:** March 15, 2021, 06:47:03 AM »

Thanks Danne. I think I have things working well now. I'm actually able to keep Global Draw On for all modes in addition to Zebras, Focus Peak, Cropmarks, Histogram, and Waveform.
Preset is 3.3k 1:1 x5
12 bit
2.39:1

SD not overclocked
No card spanning
14-bit lossless
Preview - Framing
Crop Rec Preview auto mode (what does this do? lol)

I'm pretty happy with how things are working now and have done 30 second tests without any issues. Any recommended optimizations to make things even better? I like this!

Any tips for shooting slow motion? I've never accomplished that w ML before. What are some best practices?

Thanks much all!

Danne · « **Reply #908 on:** March 15, 2021, 07:16:53 AM »

Find your own ways. Seems you're perfectly capable of doing that and if you find something extraordinary post your findings.
What's not working with higher fps? You share no info of what you are trying to achieve.

Best practices. Turn off all extras. Add them back one by one until it breaks recordings.
Apply bitdpeth reduction to 10bit. Increase if possible.
If 10bit not enough. Record 2.39:1 or reduce ratio even further.

kidfob · « **Reply #909 on:** March 15, 2021, 07:35:05 AM »

Appreciate it. I'll keep experimenting.

Slow motion is achieved by using FPS override correct? Will I need to choose a proper resolution for 60fps instead of sticking with 3.3k?

Thanks again

Danne · « **Reply #910 on:** March 15, 2021, 09:43:37 AM »

I never use fps override. I only work with presets from crop rec if not using regular hd 1080p, then I turn crop rec to off.
What you ask for is easy to test. My suggestion would be that you take a week and try and learn each and every preset, their quirks and possibilities. Pay attention to help texts. Some modes require cam to be set to 50 or 60fps in canon menu. A few presets needs to stay in x1 and a few needs to be started in x5 crop.

Hey guys. Do you think it's a good idea to start a topic comparing ALL the ML video recording options (RAW, MP4, HDMI capture, USB, ...) with most notable advantages/limitations of each option and keep it up to date with the most recent developments and statuses for each option? I mean, not for any particular camera but the overall state of video recording feature set of ML, so to speak. I've been out of the loop for several years and some recent developments just blow my mind away. I've bought and sold several cameras during this period of time. If I were aware of those features I would've made different choices. I just feel like it would be useful to many to have such a high level overview of what is possible. Then one could dive deeper into specific camera's possibilities and options.

About to edit a wiki about streaming/recording abilities with Canon EOS cameras covering HDMI, USB via EOS Utility/EOS Webcam Utility.

Collecting USB related stuff should be easy. Most are just doing 576p. Exception (so far): EOS M will not work at all. Need input about "sheep in wolf clothes" EOS M3, M5, M6, M10, M100 running PowerShot codebase.

Tricky part is HDMI. There is no easy way to tell actual HDMI resolutions in all modes without proper hardware. Cheap Full-HD USB converters (those in the 20 and lower buck/euro range) will not reveal anything about input resolution. Some TVs/Monitors will link to any input source and tell you it's 1080p.
Tried https://webcamtests.com/ but no avail. (Found the site via this link ).

Further findings: The only cam in ML project scope able to do DCI 4k (4096 pixel horizontal) is EOS R5. All other labeled as 4k-HDMI are doing UHD (3840 horizontal aka 2160p).

I just started with an uncomplete table https://wiki.magiclantern.fm/streaming:hdmi_rfc

And covering all raw recording modes ... good luck! I think it can be done if supported by devs making those custom builds.

I was thinking about something like this:

Walter Schulz · « **Reply #914 on:** March 22, 2021, 02:43:27 PM »

Quick sidenotes: Cropped raw/MP4/HDMI is not free of aliasing and moire. Amount should be the lowest, of course. And high bandwidth applies to RAW, too.
You should also mention anamorphic mode.

far.in.out · « **Reply #915 on:** March 22, 2021, 04:05:45 PM »

That was just to illustrate my point. I'm nowhere near enough informed to do this on my own. I think this deserves a separate sticky thread that would be updated by people who are in the loop and would structure and update the info to reflect the current state of things. I don't want to continue off-topic here but I'm not sure about where is the right place for such a thread.

Walter Schulz · « **Reply #916 on:** March 22, 2021, 04:17:31 PM »

On the long run sticky threads with content to maintain are prone to become unmaintained, outdated and adding to user confusion.. "Staff" discussed this some time ago and opted for wiki instead. Wiki doesn't guarantee to go smoothly and had to be maintained, too. But looking backwards on some history we are better with wiki than without.
Lookup Camera Help. Initiator put in some serious work and dropped out without being heard from him since and way before completion.

far.in.out · « **Reply #917 on:** March 22, 2021, 04:28:41 PM »

Makes sense. OK, I'll try it.

Panz · « **Reply #918 on:** March 29, 2021, 08:30:53 AM »

With February builds, shutter speed doesn't affect exposure when in video mode 3.5k or 3.3k. The numbers do change but there is no effect on the image or histogram. All other modes work as they should. When i switch to photo the exposure is correct. I tried changing shutter range, shutter lock(changing shutter from ml only), ettr, expo override but none seems to be able to change the actual shutter speed. The number changes, the exposure doesn't. I am on 5D 1.2.3

Is that a bug or is there any other option i am missing?

Danne · « **Reply #919 on:** March 29, 2021, 10:29:27 AM »

Don´t have my camera atm but I can take a look this week.
Meanwhile. Could another user verify this behaviour?

Kharak · « **Reply #920 on:** March 29, 2021, 11:46:50 AM »

Reset ML settings.

I recall once having a similar issue with “vanilla” 3.5k crop. Don’t know what it was, but resetting to ML default fixed it

Also check your Dial, is it by chance on (A+) or any of the others?

Panz · « **Reply #921 on:** March 29, 2021, 03:48:01 PM »

I tried resetting both canon and ml settings. Formatted both cf and sd and installed vanilla 28feb build but still the same issue. It's on M mode. It's not readjusting iso or aperture. Shutter number changes as it should. There is no difference though. Happened both on manual and electronic lenses. Other than that i cannot think of anything else to try.
Tried to change shutter in shutter priority mode. As shutter speed decreased 1/4000, iso maxed and the image got brighter.

Last think left to check is 1.1.3 version, although i prefer 1.2.3 for hdmi monitoring.

Danne · « **Reply #922 on:** March 29, 2021, 08:11:43 PM »

I can verify that shutter is not changeable in 3.3k preset. Tried to see what´s going on but couldn´t find the issue yet. When I build the preset I tried following the CROP_PRESET_CENTER_Z routine and probably some safe guard stopping shutter from being modified. I sees if I can find time and fix it.

Danne · « **Reply #923 on:** March 29, 2021, 09:06:13 PM »

I think the shutter issue with 3.3k preset is fixed:

Some issue with cmos 2. Thanks for reporting.

Panz · « **Reply #924 on:** March 29, 2021, 09:44:28 PM »

Thanks for the really quick fix!
Happy to help with the bug hunt. Least i can do for now.

I tried working with 3.5k x5 centered but it's not as robust as 3.3k. I always get compression error around 1 minute mark no matter what resolution i use. Console comes up and i have a few logs. The cam keeps recording but i think a few frames are gone. Is this a known issue, performance related? I can look into in a bit more if you want(upload logs, clip)
I guess one more frame per second is really heavy on card speed compared to 3.3K.
