Mavericks QT Player X “Converts” FCP X Quicktimes Before Playing
Has anyone else noticed an issue in mavericks where a prores .mov file exported from FCPX does not just play in player, instead it “converts” first before playback and then prompts you to save the file after?

Have you installed the pro codecs on your system? Quicktime does this when it encounters a codec it can’t play natively so it converts to one it can (I believe).

Quicktime X only seems to play back h.264. Have you installed Quicktime 7.6.6?

I don’t think so. I can immediately play back ProRes files right out of FCPX in QT X.

QT 7 plays the files. It is installed but it doesn’t affect Quicklooks ability to play or not play the files.
On further examination it looks like fcpx exported files are ok in quick look and qt player x. It’s our source prores files which come from vantage or episode that are the issue.

I’ve noticed this, too. QTX seemed to play all ProRes files under 1GB without issue. All files over 1GB were “converted”. If you saved the “converted” file from QTX, the resulting file was ProRes and the exact same file size as the original (non-converted) file. In all cases, QT7 opened all of these files without issue.
Any file that QTX tried to “convert” wouldn’t play with QuickLooks. All OS, codec and video software is current (Mavericks). Like Keith, I suspect the files in question were ProRes, but came from some oddball source, like maybe a camera manufacturer’s conversion utility.

Is there some kind of tag in the file that indicates origination? Otherwise, what difference could there be between ProRes files coming from different apps?

I’ve got plenty of 15-30GB proRes files that are fine. I even have a proRes file that’s some oddball 5300×1080 or something from 4 years ago (for a conference wall) that plays just fine. Sometimes old DV files need conversion, sometimes not. Can’t find a pattern.

You are probably right. It must be something that’s changed with Mavericks as part of Apple’s continuing deprecation of QuickTime. My files in question are all labeled starting with “Clip” followed by a longer number. That is why I figured they were created by some camera utility. Other files that I’ve processed with MPEG Streamclip, for instance, have no issue. These others came from a client.

An engineer that works for me says he found a thread about mavericks and quicklook no longer using third party codecs or qt to decode.
Doesn’t explain the prores files not originating from fcpx or those over 1GB in file size if those are related to the problem.
Oliver – it surprises me that if you save the qtx converted file, that it too has the quicklook problem. I’m curious if we open a converted file with qtx, will it convert again.
-
No. Sorry if I gave that impression. The converted file didn’t have a problem with QuickLooks. It had the same file size. FWIW – neither version was any problem inside FCP X. So it’s definitely a problem with the piece of junk that is QT these days.
