Mavericks QT Player X “Converts” FCP X Quicktimes Before Playing
-
My bad. Ok – so after fcpx or qtx “conversion”, it plays nicely. It sounds like a qt atom type of thing that is not in the non-apple originating prores files.
And as you posted earlier, no problems with these files in fcpx, just outside.

Actually the original file, without any conversion, plays fine in FCP X. Just a standard import (leave media in place). In my case, the original file is ProRes.

Agreed. No problems with these prores sources inside of fcpx, only outside.

Thanks Jari. From the kb, it looks as if ProRes files should playback in quicklook with no issue, but it is not the case with (at least some, maybe not all) third party created ProRes files.

I have had a few files that wouldn’t play in QTX, but they were just fine in Legacy! Some of those include ProRes LT from an unknown client source.

For posterity, I’m doing a reset of the subject and re-defining the issue:
In Mavericks 10.9.1, attempting to play some 3rd party generated ProRes .mov files through either QuickLook (spacebar) or QT Player X, results in unexpected behavior:
1. On opening, QuickTime Player X will convert the ProRes file to the same format (ProRes) before playing it and prompt the user to save the new movie on close. According to this KB, QT Player X should play ProRes without convert. https://support.apple.com/kb/HT6055
2. QuickLook does not play the movie and instead displays a still and shows the file’s size as 0 kb.
Additional info:
The issue seems to only affect ProRes files that come from third-party transcoders (i.e. vantage) or third-party cameras that record to ProRes.
The preview picture in the finder for assets that experience this problem is a 4:3 image with letterbox when the actual asset is 1080 HD 16:9. CLAP atom issue?
