ChromaKey(Avid) on manual
I discovered that in the description of the ChromaKey (Avid) plugin in the manual, I left in some lines that refer to the ChromaKey (HSV) plugin. This mistake of mine makes the description confusing and makes it difficult to understand how the plugin works. I have removed the incorrect sentences and made a few minor adjustments. I apologize for the error and for discovering it so late. Here is the link to download the corrected LaTeX file. https://limewire.com/d/MiMBE#nAmC98NvCL
Andrea, thank you very much for the update. I have checked it into GIT just now. Not sure if need new images in the manual for the new website? I have not looked. You did a lot of testing of lcms2 which others may want to take advantage; should it be added to the manual also? Not sure about current status of colorio?

1- There are no images from the website in the manual. Maybe some links need to be updated? I'll take a look. 2- No, lcms2 is still in the testing phase. It requires manual configuration, only a standard wide-gamut color profile is used, and, for now, I can't use any of my monitor's custom profiles. Finally, CinGG works internally in sRGB, and I still don’t understand how the lcms2 implementation works. For now, this patch is needed to correctly view formats in the Compositor that aren’t normally supported by CinGG (GBR, for example, as seen in the image redtruck_GBR.jpg). In short, I’m still completely confused and don’t know if I’ll ever figure it out. 3- OpenColorIO is even more complex than lcms2. You have to configure it at both the system level and within CinGG (to use it as a filter). I haven’t been able to get it to work. I’m not even sure what it’s good for: it’s designed for a “scene-referred” workflow, which CinGG doesn’t support. Maybe it can only be used for color space conversions, but I’ve never gotten that far.

why you insist on this interpretation ? and I still don’t understand how the lcms2 implementation works. For now, this patch is needed to correctly view formats in the Compositor that aren’t normally supported by CinGG (GBR, for example, as seen in the image redtruck_GBR.jpg). patch should be already in git: [root@slax cinelerra-5.1]# grep CIN_CM cinelerra/ffmpeg.C profile1_path = getenv("CIN_CM_PROFILE"); [root@slax cinelerra-5.1]# In short, I’m still completely confused and don’t know if I’ll ever figure it out.

I think documentation pointed at its usage for encoding multiple of EXRs, so not your usual movie video file source.

https://forum.cinelerra-gg.org/t/show-your-video-profiles/147 "But please do not confuse with the internal color space of CGG, that is X11 sRGB without color profile." "At this point the editor only needs to know that his monitor should be set to sRGB if color corrections are to be made with Cinelerra." Anyway, I'm completely confused: the wide-gamut images that worked the first time I applied the patches are now causing constant crashes with memory dumps. I'll try to attach one of the dumps.

I think cingg does not do any sRGB gamma encoding, but x drivers/core X server might? I guess this is true in common case or under Xwayland (that enforces sRGB for now for non-colormanaged windows per pekka's answer) But I am not sure this is true if external profile management enabled at X compositor level?

Yeah, strange. I am trying to rebuild cingg on i586, ran into some x264 bug (?) so I'll look at color management crash after I solve it first It may take some time
