I got some footage off AVID - a mix of DNxHD and XDCam.
When I brought some shots into After Effects, I noticed that
some of the materials that's in XDCAM HD422 1080p30 (50 MB/s)
has weird pixel artifacts, popping in for one frame.
The artifacts also appear on the original media files.
The weird thing is that the noise in not consistent -
I can scrub a clip, and the noise won't appear, next scrub it's there.
Also, in Avid the footage play ok - No artifacts.
