MPEG Streamclip Encoding Loop

I've been searching all over and nobody seems to be having this problem. I open a file with MPEG Streamclip and export it as an H.264. I've done this hundreds of times in the past without any problems. The last couple months however, I export it, the progress bar comes up, it appears to be working and when the progress bar gets to 100%, it starts over from the beginning. It's so frustrating and I feel like nobody else is having this problem.

Anybody come across this, and if so, do you know what's causing this problem? I've gotten very small files to export properly, but if the clip is over a minute or so long, it ends up in what appears to be an endless loop.

I've had this issue on three different computers. One time, it was a co-worker, and I was showing him the program.

I have tried trashing my prefs and that didn't help. It's weird because I can export smaller files (under 50MB) fine, but when I get over a couple hundred MBs I get this loop. It's only with H.264s too.

hey Nathan,

I'm having exactly the same problem with the same file formats.

I see this was a while ago, have you had any success?

thanks,

Rob
