Thanks again for the reply.  It does make sense to me what you suggest.  Unfortunately so far I keep getting an "Error importing AVI frame 10" message and the .mp4 is being created without picture.  I will continue to experiment there might be an option somewhere I'm overlooking.

To answer your question yes I want to use x264 as well but to have an option for MPEG4 at times.  It was just coincidence that I started first with MPEG4, actually I should try some with x264 and see if I'm successful.  Thanks again,
