I've been authoring DVD's of our film using Adobe Encore CS4. The original footage is glorious 4K 23.976 fps shot on RED at 1:2.35 aspect ratio, so needless to say, the 29.97fps footage I'm outputting for DVD is a little lackluster. I'd like to at least get rid of the "video" feel by exporting the footage at it's native 23.976 (instead of the 29.97 required by DVD's). However, when I do this I get errors in Encore ("The gap before the video clip at __;__;__;__ must have a duration of either zero, or at least 0.4 seconds").
The project is broken up into five "reels." I assume if there was just one video stream (all five reels exported from one timeline), this issue wouldn't even come up, as the issue arises in Encore on the movie timeline between these clips. But I'd really like to find a solution that allows me to keep these "reels" separate.
I've been researching the issue for the past day or so, and there is a lot of discussion about pull down, field order, flags, and a bunch of other stuff that I don't necessarily want to become an "expert" in.
I realize there is a standard for DVD's that requires all NTSC footage to conform to a 29.97 frame rate. I also realize that "pulldown" (or "pullup," depending which way you're going) refers to making 24 frame footage conform to a 30 frame format by adding/removing frames.
Almost every source states that it's best to output your footage for DVD from Adobe Premiere (rather than let Adobe Encore transcode it). Encore will then take your 23.976 footage and use it on the 29.97 DVD supposedly without issue. However, there is some tweaking that needs to be done in the export, as the Adobe Media presets used by Premiere do not work "without issue" when authoring the DVD (see the "mind the gap" error message).
