I’m not that familiar with the forum and I seem to have replied to someone else while trying to respond to your post. So here you go:
Thank you for the response!
He is definitely sending me 720×480 Apple Pro res HQ. Confirmed. He did send me some tests late last night and he must have overlooked something because he sent me some files in 720×540(which is how he is working. He has been doing this much longer than I have and says that when a project is in 720×480 he always works in 720×540.) Regardless These files look amazing comparatively, and they are in the animation codec.
I have asked him to send me additional renders in 720×540/Animation to see if this is part of the problem.
