Both MediaInfo and PPro’s built in detection think it is an interlaced video, no doubt because it was exported that way.

I’ve determined that both fields can be combined into whole frames, so the only issue now is why PPro is messing up the image in its monitor.

But it’s not particularly important. Thanks anyway. ☺

Ha, sorry! I’ll try. ????

Basically, I have a 25fps AVI file that was created (converted) some time ago from a series of progressive 25fps MOV files, but it was most likely exported as interlaced at the time, from an interlaced sequence in Premiere Pro.

I’m trying to determine whether the full frame data from the original MOV files still “exists” within this AVI file and, if so, how is the best way to deal with it in regards to interpreting it when bringing it back into PP.

I’ve found somebody on the Adobe forums with basically the same question:

Theirs was about a telecined film, but same thing. They determined, like I have, that since each field of the video is taken from the same frame of the film, that the video is technically progressive even if it wasn’t exported that way.

Which is why I was very confused to see Premiere Pro showing me a worse quality image* when interpretting this file as progressive.

HOWEVER, having now checked the same AVI file in After Effects, I can see the full frame quality in progressive, and softer quality when interlaced, exactly as I would expect.

So it seems the problem is specific to the way PPro is DISPLAYING the picture in its monitor, not how the final output will look. In fact, when exporting some of that footage from PPro into AE, the picture quality looks identical to the original.

PROBLEM SOLVED, then. But I still don’t know WHY PPro is displaying such poor quality in its monitor if I have everything set to progressive. There must be some trait of the video, its metadata or just how its fields are stored, that is throwing PP off?
