importing 24fps, jumpy

[Jerry Chan]

I’ve encountered the same exact thing. When I step through my initial 23.98 AE output in Quicktime, there are no duplicate frames, and it plays back smoothly. But when I re-import the output back into AE and drop it on the Comp icon, I get duplicate frames as I step through the timeline. After I re-output it, the duplicate frames are still there when I playback with Quicktime.

Did anyone find a solution to this?

No, the entire project was done in AE using HVX footage, which we converted to Quicktime using FCS 2.

The original render out in AE was fine. Unfortunately, I don’t have access the the original project anymore, just its output.

Yes, I imported it correctly; I work with HVX footage all the time. Again, the original output plays perfectly fine with no duplicate frames. Any issues with the HVX source footage would’ve appeared in the original render. The problem arises when I bring this output BACK into AE.

this may be a hit or a miss,but what if you re-encoded it uncompressed from FCP or quicktime player and tried importing back into AE. Then you’d know if AE is malfunctioning.

Funny you should suggest this, as I just re-exported the file from Quicktime as Uncompressed 10-bit 4:2:2, and when I imported it into AE, it seemed to do the trick. The original file was compressed with the Animation codec, which usually doesn’t have any framerate issues.
