kinda hard to explain in the title
I'm looking for a software to edit certain movie data, specificly:

subtitle descriptions (have some movies were subtitles are named "untitled" or "unknown")
audio descriptions (same as above, some are titled "audio1" instead of English or w/e)

default aspect ratio -> got some movies where the playback aspect ratio doesn't match the encoded aspect-ratio and it's kinda bugging me setting the correct aspect ratio in VLC all the time

software/tipps which doesn't include re-encoding are preferred
