I would consider extracting the subtitles, removing them from the video and audio movie file, then using a subtitle editor to properly align them and remux. Unfortunately, I only work with .srt, but here is what I use to extract the subtitle stream: ffmpeg-i inputfile -map 0:s:0 -f srt subtitle.srt L.
