imovie hd compression problem

[Diddiyo]

hi,

i have recorded a bunch of clips on a gopro hd hero cam in 720p (.mp4 files @ 30 fps). i already imported them to imovie hd, edited them together etc, added some music and whatnot. no problems so far.

however i get an error message when i'm trying to export the movie. after about 75% it gives me an error message:

A file compression error occured. The movie could not be properly compressed. The movie may contain some data that is invalid for the type of compression selected.

the settings are:
- expert settings
- movie to mpeg4, options:
- video: H264
- image size: 1280x720 HD
- frame rate: 30 fps

should i maybe be using another format? any help is much appreciated!

thanks in advance.

*bump*

i just tried to export in as a *.mov file. same problem. i have more than 50gb disk space left so that shouldn't be a problem either.

any ideas?
