Well, I got burned by a very large “gotcha” when exporting a project for color grading in Apple Color.
The project was a 10 minute story for a broadcast series, all shot P2, 1080i / 29.97. I edited in an AJA 1080i / 29.97 timeline with all the native material. At the end of the edit, I exported a Self Contained ProRes Quicktime to be sliced up and sent into Color. The Export looked correct in Color, I did the color grade, rendered brought it back and it looked all wrong. Like it was 24p stutter or something. I got burned by an extra step in the export process I didn’t think I needed.
Ok, here’s the export dialogue from Adobe Premiere Pro as I had it originally. Everything looks correct. Codec is ProRes 422, Frame Size is correct, Upper Field First is correct and Square Pixels is correct.
So I’m scratching my head on what in the world has gone wrong here. Why are my Color renders all looking like they are interlaced rendered to progressive?
See that button under Apple ProRes 422 that says “Codec Settings?” That’s the answer.
So I had to re-export the original file, slice it up again and send it through Color again. At least I could re-use all of my grades so that wasn’t a problem and it turned out not to be too much time lost.
Needless to say I have now saved a custom preset with BOTH interlace options set to Upper Field. Now YOU know and it doesn’t have to happen to you.
