A movie freezes (audio still running)

Masa's icon

Hello, I am a beginner.
I am playing mov file with 'jit.qt.movie', but it always freezes at the same point. The sound doesn't stop though.
The scene is just after an speeding scene. I sped up the clip in Final Cut Pro X (not in Jitter), and exported the mov file.

Many thanks,
