Crop mode recording (crop_rec.mo) (1:1, RAW/H.264, 25/30/50/60 fps)

[NoCp_Albert]

@A1lex, thank you for the new test crop modul 12.01.2017.

Just make a quick test, got some coruptet files and flickering during 5xcroped recording.

Will make a short video with al settings for you.

About Renatophoto record, maybe it is possible to make the correction of Black level directly in this module

[budafilms]

 - In Preview Option, in Raw menu, I set Canon instead Auto or ML Grayscale. Except the bars overlay, the image its solid and centered for shoots.

- if you load rawRec.mo and Mlvsound, you get errors in all modules. I am using mlvrec.mo

[Danne]

You can,t run raw_rec and mlv sound at the same time.

[RenatoPhoto]

Problem found: With zebras enabled the Auto ETTR changes exposure during recording..  in the first few frames.. sometimes it settles with over exposure.

Otherwise crop rec module working very well.  Video recorded with:
AETTR (Always ON)
Zebras Off
Crop module  (3X 1080/720p)
1920x1080 at 30 fps

Post with ACR and Vegas pro 13

Unfotunately Youtube does lower the quality.. and I exceeded my Vimeo account.  Looks better on computer.

[GutterPump]

Even with YT compression, the footage is very clean ! Well done !

[RenatoPhoto]

The exposure flickering happens with or without zebras... It seems to happen when the recording button is pressed before Auto ETTR has finished settling its exposure.
Was able to catch it in this video and later reproduced if start button was pressed while AETTR is still changing.
Also minor problems:
1. Notice the exposure flickering after stop button is pressed.
2. Notice how the Raw Histogram changes during recording to wrong settings.

[D_Odell]

What stops 3x to have higher resolution in this module?

[RenatoPhoto]

Oh my, new Experimental build for crop_rec with 10 Bit and 5D3-123 Thanks A1lex! 
Get them here: https://builds.magiclantern.fm/experiments.html

I will have to test all the new updates but have not time now!

This is the new stuff for testing here:

a1c01bb: Raw backend: fix black borders on raw previews

4081e14: Merged raw_video_10bit_12bit into crop_rec

f849355: mlv_rec: fix bad merge (to be tested)

12f156f: Moved bit depth setup from raw_rec/mlv_rec to raw backend; raw overlays should now refuse to run at bit depths other than 14

a31228c: raw_rec, mlv_rec: minimize roundoff error when scaling black and white levels
(using --black-fix in mlv_dump should be no longer needed)

[NoCp_Albert]

During my test for the magiclantern-crop3x.2017Jan12.5D3123 without MLV_rec and MLV_sound I found this Morning the new Test Module magiclantern-crop3x.2017Jan13.5D3123.

I test the new Crop Module with MLV_rec and MLV_sound, A-ETTR "always on", RAW_rec and raw_twk.mod not loaded.

Let me say, really a pleaser to use this Modul now, Thank you

1.1 Normal 1920x1080, 14 bit, ok.
1.2 Normal 1920x1080, 12 bit, Message RAW error, but the recorded footage without problem in MLW-view and in Lightroom, resolution can not be changed
1.3 Normal 1920x1080, 10 bit, Message RAW error, but the recorded footage without problem in MLW-view and in Lightroom, resolution can not be changed

2.1 3xcrop 1080/720, 14 bit, ok.
2.2 3xcrop 1080/720, 12 bit, ok.
2.3 3xcrop 1080/720, 10 bit, ok.

3.1 5x centered crop, 14 bit ok
3.2 5x centered crop, 12 bit ok
3.3 5x centered crop, 1920x1080, 14 bit ok
3.4 5x centered crop, 2208x1242, 14 bit ok
3.5 5x centered crop, 2400x1320, 10 bit ok - continual
3.6 5x centered crop, 3008x1320, 10 bit ok - 12 sec
3.7 5x centered crop, 3520x1320, 10 bit ok - 4 sec

All DNG files with ML-Mystic converted to DNG for Lightroom ACR without any correction looks nearly perfect, will prepare a video with short clips for you.

1.2 Normal 1920x1080, 12 bit, Message RAW error, but the recorded footage without problem in MLW-view and in Lightroom, resolution can not be changed

The RAW error is from ETTR - it doesn't know how to handle 12-bit data. It's a race condition - if it decides to meter the exposure when recording is starting, you may get this as a side effect. Or, if the metering starts right before you press REC, and the process continues in the first few frames, the exposure can be screwed up completely (because 10/12-bit data interpreted as 14-bit looks like noise).

Not sure what's the best way to fix it: lock the GUI during adjustment (could make sense when using SET as a trigger, but not in always on mode), continuously check for recording during the metering process (and give up), or delay the recording somehow until the metering finishes.

What exactly do you mean by "resolution can not be changed" ?

[NoCp_Albert]

@A1ex

First of all, I was really impressed today about the completely Module, for me nearly on the way to include the perfect working 3xcrop 1080/720 Module together with the 5x centered Crop and….the 10bit, 12 bit and 14bit recording. All I testing today with the 5D3 – 123 Firmware was perfect, tomorrow I get out in the real world. I don’t expecting to work in the Standard Module 1920x1080 14 bit also with 10 bit and 12 bit as you make it possible now. Forget all the Issue’s I found in the previous Test Zip from 12.January, I do not found any Problem today, no corrupted Files, no flickering, also without Gray scale during the records.

Thanks for the Info about RAW error, I understand your Info because I was trying out first time Auto-ETTR “always on” The RAW error message stays for 2-3 seconds, get off and came back during my 10 sec. recording. Tomorrow I try with ETTR by" Press Set".

What I mean with Resolution cannot be changed, maybe is a problem of the old German with his bad English. I just was wondering because the 12 bit and 10 bit was working in the Standard Size 1920-1080, so I try to get with 12 and 10 bit bigger Frame size, similar to the crop mode version maybe 2400x 1320 in 10 bit recording same like the 5x centered Crop mode or otherwise an higher FPS rate up to 50.

I am just dreaming sometimes. Magic Lantern is a Dream, thanks for a great work to the ML Team

Here some testing footage 

[RenatoPhoto]

Testing Latest : magiclantern-crop3x.2017Jan13.5D3123

a1c01bb: Raw backend: fix black borders on raw previews

Yep, this is working on raw previews for 14 bit.  On 12 and 10 bit the Gray Preview is frozen when recording starts.  If 10bit and 12bit preview during recording is not available could it swing back to Canon preview?  In this way at least we have the proper framing with the Gray Preview and then we can get some idea of the scene by looking at the Canon preview.  For now I click on the zoom button and get to the 10X zoom just before I start recording.

4081e14: Merged raw_video_10bit_12bit into crop_rec

Working great!  Crop rec module is doing its thing. 

f849355: mlv_rec: fix bad merge (to be tested)

mlv_rec is working very well with 10/12/14 bit video.  Tested sound, card spanning, resolution, and found no problems.

12f156f: Moved bit depth setup from raw_rec/mlv_rec to raw backend; raw overlays should now refuse to run at bit depths other than 14

Yep unfortunately the frozen gray preview is of no help..  as I mentioned before maybe if possible the canon preview should be put in place only during recording.

a31228c: raw_rec, mlv_rec: minimize roundoff error when scaling black and white levels
(using --black-fix in mlv_dump should be no longer needed)

Well done, 10bit footage looks very well.

OTHER PROBLEMS:

Using crop_rec with 5X setting:
I recorded some videos with zoom and some without.  Always previewed them using the play button and then sometimes the playback got corrupted.  The video was recorded ok but the playback looked like this (caught it with screen shot):


If the camera is turned off and on then the video playback looks proper.

-----------------------

More Video Playback problems:

When erasing or playing videos with mlv_play
after pressing the erase the previous video shows up..  this only works for two or three videos and then just get a black screen
During playback the same issue happens.. only can review three videos and then a black screen without the video.
To erase more videos have to get out of LV and back in.. then the other videos appear.

This is great stuff guys!  I really appreciate all of the many hours of work that you have put into this great project.  

[NoCp_Albert]

@A1ex, Renatophoto

All 14bit records are showed in mlv_play, but mostly maximum 3 and then comes the black screen. The Info bar is running for maximum 8 records if you go back with the wheel, than it’s completely black. Sometimes get the also10+12bit video showed, not everytime, not when I get the "RAW error" message during recording. Maximum I get 8 records in mlv_play, but the records all ok.
 
I try today ETTR with push Set" and also Snapshot mode, the RAW error messaged is there also, recorded footage is ok.

[axelcine]

What a Christmas present - thanks A1ex and all you other excellent Canon Magicians. I know that all of you - of course - know exactly how happy we all are with your work. But it can't be said enough: You guys take terrific cameras and turn them into super machines. Our daily work with the cameras benefit tremendously from your work. Many very difficult tasks are a lot easier now, and the overall quality of our work is vastly improved, thanks to you guys. My town, Aarhus in Denmark, is the European Culture Capitol this year, with lots and lots of photogenic events, so ML will certainly prove its worth again and again. Should you happen to be in the vicinity, I'll pop the bubbly.

You might want to look it up. Google Aarhus Denmark - lots of info is in English as well as Danish...

[NoCp_Albert]

@axelcine

Axel, as you say My town, Aarhus in Denmark and my Home City Paphos in Cyprus, is the European Culture Capitol this year, with lots and lots of photogenic events, so ML will certainly prove its worth again and again. Should you happen to be in the vicinity, I'll pop the bubbly.

[GutterPump]

I wonder if one day we will be able to use the crop mod with a preview like the 3x crop mod but with a resolution that we can choose, higher than 1080, like the 5x centered crop. With the new 10/12 bit functionality, it will be wonderful.

If A1ex or others devs can point the finger at this possibility, Magic Lantern will reach its peak, If this is not already the case.

I know it sounds insolent, knowing the enormous work and discovery that the developers are doing now. But when I see the evolutions that are getting faster and faster, I'm hoping.

[goldenchild9to5]

Pre Video Shoot Test.. Let me know what you guy's think of this look. If anyone is from the NY, CT area and would like to be part of this project and help out let me know.  By the way thank you Team Magic Lantern for this wonderful Upgrade

5D Mark III using Magic Lantern RAW (720p Mode in 3X3 Crop Mode, was the older built) 
Lens Nikon 50mm f1.8
Color Graded using Davinci Resolve 12.5.3
 

[GutterPump]

Did i try too.

5D mark III -  firm v.113

Resolution : 3104 x 1320 @ 24p - Upscale to 3840 x 1632
Bitdepth : 10bits

Not continuous but allow to record arround 800 frames with card spanning.

DNG was extracted with the last MLV_DUMP, i not met any issue or corrupted files.

To get an idea : 7 mb by DNG -  340 frames = 2,3 gb

Was a pleasure to  color grade with these 10bits footage.

[child01]

Sorry, may be I missed something, but why I don't see crop_rec module in the Jan13 nightly build?
I've tried to copie-paste it from Apr02 nightly build but it didn't work((
So why there's no crop_rec in Jan13?

[RenatoPhoto]

Ok ok... here is my test recorded at 60 fps rendered at 29.9 fps with crop module: 1:1 3X giving resolution of 1920x648
TESTED: magiclantern-crop3x.2017Jan13.5D3123
Get it here: https://builds.magiclantern.fm/experiments.html

[RenatoPhoto]

I am experiencing problems with 1:1 (centered x5 zoom) settings when the resolution is above 3008x1320, at 3008 I have no problems but at 3040 I do!
magiclantern-crop3x.2017Jan13.5D3123
Using mlv_rec module.
The problem begins when the camera stops due to skipped frame or stopped by button press.
After the camera stops I have to pull the battery out since camera stops responding.
The video file gets recorded and have no problems.
After rebooting the camera cannot play back the file it gets a black screen.

If I flick the video lever a couple of time I get camera Err 80.

Also confirm the problems is with mlv_rec..  Using raw_rec does not give me any problems and I can record to max resolution  3574x1320

[NoCp_Albert]

@RenatoPhoto

I test your report and confirm the same problem, with MLV-rec at 3040x1320 10,12 and 14 bit. By 10 bit I get record toime about 8 seconds, then "Automatic stop" and "Bussy", after a few seconds I switch the Camera of and start again, press Lupe for 5x crop and then record working again 8 seconds. With 3008x 1320 10 bit Camera stop after 8 Seconds recording but after 3-4 seconds comes back automaticle in Record Mode.

As you say, with RAW_rec this problem is not happen.

[RenatoPhoto]

5D3.123  using crop_mo 3X at 60 fps
magiclantern-crop3x.2017Jan13.5D3123

There is a aprox 28 pixel black border on the top of the frame.

[DeafEyeJedi]

...Also confirm the problems is with mlv_rec..  Using raw_rec does not give me any problems and I can record to max resolution  3574x1320..

Confirmed this on my end with 5D3.123 as well.

There is a aprox 28 pixel black border on the top of the frame.

Unfortunately atm this is to be expected afaik.
