I have a problem, importing lossless mkv videos to Wondershare Filmora program. Video is not imported correctly, artifacts are seen. I have no problem if the video is compressed, at any quality. Why?
Probably the format. The lossless h.264 RGB 4:4:4 format is not very well supported by video editing software. FFMpeg supports it, since the guy who implemented RetroArch’s video dumping added it to it years ago.
