Just a quick question to if anyone has seen anything like this, I know its corruption, but not sure what's caused it, only happened once so far, details are C100 MKII with new Sandisk SD cards
Can you describe the circumstances under which you are seeing this happen? I've seen that kind of tearing at the very beginning (first frame or two) of certain clips. Also, I've seen VLC introduce that kind of artifact to a clip even when there is none in Premiere.
Seen this before in Premiere Pro. As Quickhit says it's just the first few frames. In my experience it wasn't there on the card when playing back on the camera or in QT player - just Premiere.
