So I have a mkv file with embedded subtitles, but when i try to edit the video the subtitles aren't there. does anyone know how i can have them on the video so when viewed after exporting they are on there?
MKV files are not natively supported in Premiere Pro, much less subtitles from this format. You can upvote the feature request here: To add support for .mkv or Matroska video format – Adobe video & audio apps
Perhaps there is a workaround for transcoding these files, but nothing that I can recommend personally. Sorry.
