I am needing to extract and embed scc files with 608 captions. I am pleased to see that transcoding without frame rate changes now preserves 608 intact, and there appear to be extraction and embed functions but they do seem to have bugs for my files at 1080p2997. Are there any developers willing to take on a paid project to fix whatever is the issue? Here are the commands I am working with. Embed: "C:\FFmpeg\ffmpeg7.1_2024-12-14\ffmpeg.exe" -i "C:\Users\Captions\AIM-2301_premiereDF.mp4" -i "C:\Captions\AIM-2301_premiereDF.mp4.scc" -map 0:v -map 0:a -map 1 -c:v copy -c:a copy -c:s mov_text -metadata:s:s:0 language=eng "C:\Captions\AIM-2301_premiereDFcopy.mp4" Extract: "C:\FFmpeg\ffmpeg7.1_2024-12-14\ffmpeg.exe" -f lavfi -i "movie=\'C:\\Captions\\AIM-2301_premiereDF_ffmpegEmbedscc.mp4\'"[out+subcc] -map 0:1 -c:s copy "C:\Captions\AIM-2301_premiereDF_ffmpegEmbedscc.scc" https://drive.google.com/drive/folders/13NXvUgE1EIyLR4WBw30l4NVtS5w33EM7?usp=sharing The file outputs are included in that drive folder. Please don't distribute the files online, but you can use them for testing. The folder will go away when the job is complete. I have requested sample files for distribution from the content provider, but haven't received those yet. The objective is to fix the character duplication and data spill out that is happening during extraction and embedding of scc files for these resolutions. I will try to get some 1080i samples also, but don't have those available in source file form at the moment. There will be other captions related projects available once this one is complete.
