One was originally an MP4, the other was originally an MKV. So if a simple file renaming wont work what about a transcoding? I used handbrake and reencoded 2 files. AME sees the file but won't import it which is really weird because I have no idea why it's doing this. I can't rename a file from mkv to mp4 for it to work. UPDATE: Ok, so I've done some testing and this is what I've figured out. could not read from source' (this is probably more important lol) I'm also having a new problem where for some reason whenever i click on a video file it says 'could not be imported. Regardless of above is there a way to make media encoder play nice with mkv or do I have to just keep renaming them? Does it support multiple video tracks? If it does then I see no difference between the two. I know they both support multiple audio tracks and subtitle tracks. mp4 and it works fine since the extensions are just containers which made me think, what is the difference between mkv and mp4?

I have some MKV rips I'd like to compress using AME, but for some reason it can't read MKV files.

Handbrake vs adobe media encoder
