AVC-intra 100 very slow
on May 3, 2013 at 2:09:03 pm

Hi
I currently encode XDCAM files to ProRes prior to editing, but we are looking to develop an MXF workflow so I'm testing AVC-intra100.
While the picture quality seems fine the encode time is massive.
A one hour XDCAM clip takes about 40mins to transcode to ProRes422.MOV, but to AVCintra100.MXF it takes 2hours 40mins - six times as long!!! Surely this can't be right? They are both iFrame 422 codecs... I've tried on a few different Macs but all give similar results. Can anyone shed light on what's happening here?!
Thanks
