Righto. Thanks. That's hardcore! I'd better learn me some functions math.  :P

2
Ah, thanks! I see now. But if you don't know maths, there is no label to understand what has been selected.  ???

I see the tags now in ProRes export ffmpeg Anatolyi. But whatever preset/space/gamma is exported it just writes default 1-1-1 tags. Maybe this is mac only?

3
Oh. Not sure what you mean exactly. How do I restore the 'old' preset values dropdown? I can't write math expressions!

4
The 'Transfer Function' is just raw text code. I can't select anything here. Shouldn't it be a dropdown selector?

5
Updated ver1.11 shows me error for 'Transfer Function' dropdown:

Ah! None of the following exports show these tags (Color primaries, Transfer characteristics, Matrix coefficients) on my Mac with Media Info app (or Finder > Get Info).  :o

422LT
422
422HQ
4444
H264_AppleAV

The only export so far that has tags (1-1-1) is H264_FFMpeg! How strange.

Here's 422 Anatolyi (MLVApp v1.11, OSX Mojave)

See https://www.magiclantern.fm/forum/index.php?topic=25440.msg232207;topicseen#msg232207 Gamma shift issues on Mac / NCLC tags

Is it possible for correct metadata colour tags to be added to ProRes output from MLVApp? In ProRes outputs the tags are missing.

Untagged files are at the mercy of being displayed un-colour managed by apps and OS.

If you've ever battled with the Apple 'QuickTime Gamma shift mystery', then the following links should be required reading (and watching). This is peculiar to Apple devices, but should make informative reading for all involved in colour pipelines.

Short answer in first post here: https://forum.blackmagicdesign.com/viewtopic.php?f=21&t=101253

Resolve 16.2 latest solutions described first post here: https://forum.blackmagicdesign.com/viewtopic.php?f=21&t=114047

Excellent video explanation here:

Summary: Our rendered files must include the correct colour tags for other apps to do correct display transforms and so avoid the gamma shift peculiar to Apple display devices.

The tags in question are visible in the 'Get Info' dialogue. More detailed info can be accessed by installing https://mediaarea.net/en/MediaInfo

Resolve 16.2 now has a way to accurately tag exported files for display consistency (see the extensive Blackmagic Forum thread).

Can you render DNG - Cineform from Resolve and play it with MPV, just to make sure there is no OS issues causing this.

Hah! That worked. Thanks @Kharak MPV plays the CF file rendered YUV 10bit and RGB 16bit option from Resolve from DNGs.

Thanks @Danne @Kharak

Have installed MPV player. CF file rendered from MLVApp crashes it. The only app playing the file correctly is Resolve so far.

@Danne Happy to render out to Cineform if @masc requires. Don't know how to render using ffmpeg command line though.

I had to remove my re-install of Cineform Studio from the other day as it kept crashing. Confirm that QuickTime OSX doesn't play CF files natively (even with CF Studio installed) – it does some sort of converting in that case. The player that did use to work natively with CF was the old QT7 player – long gone I believe. :(

The man who co-invented/engineered CF is David Newman https://cineform.blogspot.com/ He might be able to help out – and would certainly know about the active metadata side. He's very approachable.

PS Clarifying: also for me CF only plays [smoothly] in Resolve. All other players don't play at all, whether CF Studio is installed or not. QTX player converts during load if CF is installed – doesn't play at all once CF Studio is removed.

@masc

Agree with @Kharak that basic Cineform 1080p should always play like butter as it was designed for lower powered systems I believe (apart from the Film Scan flavours!) If in Mac, there used to be a system preference pane that controlled certain codec functions. Might check there if appropriate?

Re QT gamma shifts in Resolve/Mac read this thread on the Blackmagic Forum. The definitive answer:  :D https://forum.blackmagicdesign.com/viewtopic.php?f=21&t=114047

Found an old version of GoPro Studio on an old backup disk. Seems to have installed ok on Mojave. Can confirm that file exported from MLVApp now plays back fine so far in this app (GPS).

@masc Can confirm the result here on Mac 10.14.6

In the old days one had to download the Cineform app before the files could be played. I think there is a decoder element which is required. Owners of Premiere Pro should have this [decoder] already installed because I think Premiere ships with Cineform support. Anyone confirm?

@masc The range of corrections it carried in metadata included primary, image scaling, vignette, sharpness, LUT looks. It was a mature system. How that would work in MLVApp I have no idea!  :o

MLVApp has the greatest out-of-the-box colours for ML. If somehow even the very basic primaries and transform adjustments in MLVApp (which are hard to match in Resolve) could be carried 'live' into the Resolve timeline, then the two would be a ML powerhouse. :)

Probably off-topic, I know…

@masc It did happen! :) Any cineform file that carried the cc metadata would carry those corrections through to any timeline hosted by another application. It used to work in FCP7, Vegas, Premiere, and if my memory serves me right in early Resolve. You tweaked the colour in Cineform-Studio and the correction would appear in the edit timeline. I used it for years like that.

I'd show you now, but alas the Cineform-Studio is discontinued and doesn't run on anything higher than Mountain Lion I think. :(

Thumbs up for Cineform codec. I used it for years. It produces a tad large file sizes though.

The active metadata concept was awesome. I'd colour correct in the Cineform-Studio app, and edit in FCP7. As you do the corrections, they show up instantly (without rendering) in the FCP timeline.

Imagine if we could harness the awesome colour of MLVApp carried in metadata through cineform files – but edit in Resolve and use its render power.

General Development / Re: How to run Magic Lantern into QEMU?!...
« on: July 10, 2020, 10:10:46 AM »
*UPDATE*

Decided to start over again. Deleted qemu-eos folder.

Followed these excellent video tuts: https://www.magiclantern.fm/forum/index.php?topic=16012.msg191686#msg191686 and https://www.magiclantern.fm/forum/index.php?topic=2864.msg190851#msg190851

Installed with no error messages.

Partial success: I can now get to the qemu canon screen. But the keystrokes do not control navigation. I can see that the keystrokes are received at the terminal – but no menu navigation happens. I read an @a1ex post which suggested adding the Terminal to Security panel. This allowed me to control the menus with the arrow keys one time – but subsequently froze, and hasn't worked again.

Ideally I'd like to be able run qemu from a custom image of my physical SD card– but am having trouble making this work also.

Any suggestions?

I have read the thread, the README and searched.
Mac OSX Mojave 10.14.6

First attempt at installing QEMU in my local environment.

Install itself seems to be ok, but get error screen when attempting to run:

/path/to/qemu-eos$  ./run_canon_fw.sh 5D3,firmware="boot=1"




Why the message about 1.2.3? The code I copied to the sd.img was 1.1.3 So…

1) I mounted my camera SD card (with my current build on it) and copied the files to the sd.img as usual. Is this correct?

2) "For models that use a serial flash, you may have to dump its contents using the sf_dump module, then copy SFDATA.BIN as well." Should I be doing this for 5D3?

All I have in my QEMU/5D3 folder is:

debugmsg.gdb
ROM0.BIN
ROM1.BIN

Thanks.

If this is what the ACES converted to rec709 looks, it is wrong. While I don't know what the scene looked like, I don't believe it looked like that.

@ilia3101 Yes, I suspect that it's wrong also! Still researching… :)

I am asking some questions on the acescentral thread re this IDT/DCTL issue. Will report back here with any pertinent findings. :)

23
Closer examination show a bias towards purple with these DCTLs. Continuing this discussion on the DaVinci Resolve and ML Raw thread here: https://www.magiclantern.fm/forum/index.php?topic=15801.msg225208#msg225208

@baldavenger

Hi Paul

Firstly, thank you for your development and a highly informative read here.

I'm continuing this discussion from over on the MLVApp thread here: https://www.magiclantern.fm/forum/index.php?topic=20025.msg225175#msg225175

With help from @ilia3101 I've taken the CTL data from the test results in this thread *edit* https://acescentral.com/t/results-from-an-idt-evaluation/2229 and translated it into DCTL. Now I have some questions!

1) To what extent do your existing tools offer this already? (e.g. An IDT or DCTL for 5D3 ML raw to ACES in Resolve). I have your ported DCTL files installed and am not sure whether they cover the same ground, or exactly which DCTL to compare.

2) With the translations we have done today (from the data on that acescentral link above) the files look very biased towards purple. Can you spot something amiss in the translation?

Cheers!

Ok how about this: https://acescentral.com/t/aces-idt-dctl-generator/2566

Oh My God! That looks ****in awesome! Thanks for the great find @ilia3101 And it's only 4hours old. Syncronicity at work. :)

Playtime. :)

PS Hope all this will work with MLVApp also! :P
