The G’MIC manual has the option “apply_video” which works on mp4 and avi. Could this work with a LUT? Is there another library which has a better way to process a raw video file from the command line?
Maybe look at ffmpeg, you can use the 3dlut filter, or maybe use an HALD CLUT, depending whattype ofLUT you are talking about.
Thank you for the suggestion. I want to start simple, with a pre-defined LUT like those made by camera manufacturers. Would ffmpeg work with those?
I want to be able to quickly make comparisons between normal and log-recorded video, so I need a one-step method to process the log-recorded video files. I have plenty of computing power, so that part is not an issue.
Probably, the link I posted before to the ffmpeg lut3d filter section lists the supported formats.
