I’ve been converting my physical movies to m2ts and using mkvtoolnix to
convert them to mkv format with the intent of eventually converting them to mp4
for playback on most devices. Thats why I want the mkv or mp4 file to have
burn-in/hardcoded subs. The subtitles are PGS or .sup format, which is a
picture based format. I’ve been reading the overlay video filter section of the
ffmpeg site. I'm trying to overlay (burn-in/hardcode) the pgs subtitles over
the video stream without having to re-encode the video file and lose picture
quality. Is this possible?
No. Burning in makes the subs part of the pictures.
