M4V video files exported from Final Cut Pro are not playing

[mrm]

@Const

is there a flag in PS I can flip to make it work?

Maybe! Here’s a list of the three settings you can tweak to ensure the video gets transcoded:

Confused about video. Still can't seem to get them to show up

Ah! I didn’t realize the videos might be enormous. I bet the transcode operation is getting timed out, so the asset fails to import. If you don’t need it transcoded, you can tell PhotoStructure not to bother. There are three settings you can pay with: I’d use either the first or last one. You can see these tag values with exiftool: exiftool -VideoCodec -CompressorID -CompressorName -mimetype /path/to/file.mov

(In that post I was suggesting he avoid transcoding, but in your case, you want to ensure transcoding).
