[Feature Request]: MXF File Support

[whois13-eng]

Describe the feature

We utilize MXF as our house wrapper for video files and we'd love to use Vibe for audio transcription as it has a very simple interface. It works well as is if we use a MP4 wrapper, but we'd like to not have that step if it's possible. This would make the application very easy for our users to use (and for us to document). MXF is a very popular format in our world (broadcast) and if we found a tool that would let us continue to use that format while getting the audio transcription, that would be awesome.
