I'm trying to convert a bunch of movies into h.264 mp4's using FFMPEG. These movies are sourced from various portable camcorders such as the Flip Mino HD and the Kodak ZI8. One issue I'm having with video from the ZI8 is it seems to be causing FFMPEG to segfault.
Here is my command:
ffmpeg -i 'XmasSailor720p60fps.MOV' -threads 2 -acodec libfaac -ab 96kb -vcodec libx264 -vpre hq -b 500kb -s 484x272 XmasSailor.mp4
Here is the output:

Segmentation fault
I'm wondering if anyone else has ran into similar issues. I wasn't able to find anything helpful via Google.
Another question I have is if anyone knows of a company that offers paid support for FFMPEG.
Thank you for your time.
