QT opens file, FCP rejects it. who can tell me why?
We have created DV25 and DV100 MOV files which open perfectly fine in Quicktime, MPEG stream clip and VLC. 29.97 framerate and correct resolution. Yes when I drag into FCP it says its an unknown or invalid file.
When we drag in other DV25 and DV100 files that FCP has generated during export they work fine in both QT and FCP. We have compared media info using various applications and can find no difference.
Who can help us find out exactly what is wrong with the file that FCP wont accept it?

How did you create them?

Open a clip in QT and “Copy”.
Open a new window (Com-N) and Paste.
Save as Self-contained and see if its works in FC.

OK I’ll describe the workflow. My company develops an asset management solution and we wrote final cut plugin (display a menu item in Import menu) which calls a web service to convert DV files that our system manages and converts them to DV25/100 MOV files (Mainconcept DVPROHD directshow filter->our MOV muxer filter). It then imports them into the project using Final Cut XML. It appears that 1 out of 3 of these files is valid for QT but not FCP and we cannot figure out why. We spent hours and hours comparing media info and still no clue.
Unfortunately we cannot use any workaround such as first opening in QT, and then resaving because that would ruin the seamless workflow which our customers demand. And unfortunately it appears that the QTSDK for Windows does not have DV/DVCPRO Encoders which is why we wrote our own software.
Our Mac developer here is having an impossible time figuring out how to resolve this problem, because we cannot find out what is wrong with the file. If we knew what exactly was wrong with the file instead of a very vague invalid file dialog I’m sure we could fix it.
Please help.

All the codecs you listed only work in fixed frame sizes and audio format. QT is more flexible than FCP. Check that your DV is 720×480 and DVCPro is 1280×1080 . I believe audio has to be PCM. Make sure the wrapper you’re sending FCP is not changing/scaling anything.

The DV25 MOV file can be downloaded from

It’s 1 minute and 4 seconds and 150mb. I begun by trying to send a much shorter sample file but found that if the video was less than 1 minute and 2 seconds FCP actually opened it OK.
