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
