And to be even more fair, the ceremony cuts had mostly 1 second dissolves and that’s when the processing hiccuped a bit. If I made that ceremony with straight cuts, it processes in faster than real time. AVCHD to AVCHD! With CPU only processing the dissolves rendering speed was much less noticeable, but that was due to the lower overall speed anyway.
Now if you are talking SD MPEG video, you are talking about 4-5x real time renders.
