Hi Folks,

I've one particular sequence that won't render using H.264. The progress bar suggests that it's working, but the generated .mp4 file stops growing in size.

I've attempted to run the generated script manually, but it doesn't make anything:

Rendering of "_loader=1" finished

I can get over this by rendering into a DV file then compressing elsewhere, but it's a pain...

any suggestions?
cheers,
Rob

I have the same problem - The progress bar suggests that it's working, but the generated .mp4 file stops growing in size. There is no problem with smaller files, but during generating something bigger this above happed.

Is there any error console to check what is going wrong?
