Weird One-Frame-Zoom at End of Clips in Exported Video
Hi All,
I’ve got a strange problem happening with FCP. I have an interview that I’ve cut together from two different cameras. I have two tracks of footage–one from each camera. They are stacked on top of each other, and the top one is sliced in many many places as cut back and forth between the two subjects.
Everything looks great in FCP, I like it, I’m ready to call it final…and then my export does something weird:
At every cut between the two tracks, there is a one frame zoom in the upper track of the footage. It’s not dramatic, but it’s enough that every cut looks jarring now. I’ve never seen that before.
The top track of footage (the one that is having the one-frame zoom problem) has the following format properties:
-Vid Rate: 29.97 fps
Frame Size: 1920 x 1080
Compressor: CineForm HD/4K/3D
Data Rate: 9.3 MB/sec
Pixel Aspect: Square
Field Dominance: Upper (Odd)The bottom track (the continuous clip), has the following format properties:
-Vid Rate: 29.97 fps
-Frame Size: 1920 x 1080
-Compressor: Apple ProRes 422 (HD)
-Data Rate: 26.62 MB/sec
-Pixel Aspect: Square
-Field Dominance: Upper (odd)Any ideas? The upper track footage zooms in for one frame every time it’s cut to, and back out for one frame the second before it cuts away. Could it be since I used a trial Cineform converter initially before I even started editing it?
Any help would be greatly appreciated.
Thanks!

Sure looks like the Cineform codec isn’t playing nice… try transcoding one of the cuts to this camera to ProRes, import it and cut it in. Then export that section of sequence and see if the problem continues.

Hi,
I’ve exactly the same problem! all my footage is apple pro res and the ‘weird one-frame-zoom’ is when I have a text fed out on the clip.
Sometimes even between two clip ( always same format/codec..)
I export in quick time current setting.can’t find any other topics about it! please help!
thanks

Hi guys,
I’m also having this problem, all of a sudden, randomly. The footage I have dropped into two separate timelines has been Apple ProRes 422 LT, and the other an uncompressed full quality QT movie. Then when exported as self contained QT movie it does the ‘weird one frame zoom’ on cuts.
Anybody been able to sort their issue out?

Hi
This thread hasn’t given any solution to this problem.
I now also have a Prores 422 export that shows minor picture scaling (<5%) jumps at random. In canvas there are no such irregularities – only on the exported file. Exporting this “bad” mov file as h.264 shows the same problems. I have been using my iMac for 2 years without this problem.
Anyone have a solution?
Thanks

Hi Peter,
I seem to have located my issue, tell me if the same goes for you.
It seems to be that QuickTime Player X has the problem, not the exported videos, because when I play the videos in QuickTime 7 it is flawless, and again when I burn the exported files to DVD – plays no problem!
Please try playing your exported videos in QuickTime 7 if you haven’t done so already and let me know if you’re still finding the scaling problem.
Cheers
Tom
