Then I frame capped it, exported as .tif. Opened it in Photoshop and Saved As .PNG.
I see.
As for what I was talking about, well, if you look closely at the image, for example the place I circled, you can see slight horizontal line artifacts (combing artifacts). That's caused by bad de-interlacing (converting 1080i to 1080p) not removing all the interlacing. If you don't remember deinterlacing it yourself, then premier probably auto-deinterlaced it for you?

Lolwut..?
It says it's fieldless (progressive)... Does that mean the source came like that? If so then shame on Apple/Yahoo/Whatever you got the source from.
Ok, look at the source directly. if it has lots of lines across it like this ![[Image: Weaving.jpg]](http://upload.wikimedia.org/wikipedia/en/0/00/Weaving.jpg)
then it's interlaced (1080i). If it's clean, then it's progressive.

This is the second part of what I was talking about previously. The correct frame size for that picture should be 1920x1080, rather than 1440x1080. And after you crop top and bottom it becomes 1920x800, which is the correct aspect ratio for the movie. But that's not important for comparison purposes (is only important if you're going to encode it), so I'll shut up about it.
