Starting point: MOV - QuickTime camera files with ProRes or H.264. Some codecs inside need transcoding before browser playback. Only the selected tracks carry over, so pick audio and subtitles first. Encode MKV (H.264 / AAC) from MOV at a bitrate near the source, and confirm the audio track before converting.
