I make movie montages (or supercuts as they're more widely known) and I'm constantly running into this issue. Here's my workflow:


1) Convert movie to .mp4 using Handbrake

2) Extract clip from converted movie using MPEG Streamclip

3) Import clip into FCPX


In FCPX I have the project's framerate set to 23.98 at 1280x720. When converting a movie to .mp4, I set the framerate to 23.976 (NTSC) in Handbrake.


- Clips play fine in VLC.

- Clips play fine in the Event Library.

- As soon as they're moved into the timeline, playback is choppy.


This doesn't happen with all clips, and there doesn't appear to be any rhyme or reason as to why one plays fine and the other doesn't. What am I missing? What should I be looking for when comparing clips?
