When exporting Sony A7C 4K video there is no sync audio on the MP4 file upon export. However if I choose to render the audio track seperately as a standalone file it works fine. There is audio playback within the app itself when trimming.

Note: states unsupported file type on import but claims to have full audio on export which it doesn't?
