I'm working on some low-midrange VFX for a local production; their post workflow is all 4k (shot on Red, edited on PPro). They're sending me trimmed PPro seq, I bounce the individual shots to AE using the Replace w/ AE Comp feature, work on them, render the shots out and send the finished stuff back to the client. I've been exporting XAVC .MXFs through AME (XAVC Intra 4k Class 480 3840x2160), but I've found that a good portion of the shots render out 1 frame short. The source and output settings are both 23.976 progressive, so it's not a DF/NDF issue. The comp length, ins and outs in AE are definitely all fine. Rendering out in a different codec (QT Animation or DPX, for instance) works perfectly fine. Adding a frame to the end of my comps doesn't seem to do the trick, either, for some reason. Any suggestions?
If nobody can help fix the problem, does anyone have any suggestions for alternate codecs? The colorist has specifically asked that I NOT send QT Animation files; DPX files end up being ENORMOUS... ~170 frames clocks in at a little over 5GB. Everything still needs to go to color, so I need something that's as high-quality as possible. ProRes is out. DNxHR is still a couple of months away. They'd prefer self-contained files, rather than image sequences (although, 'eff 'em right in the A, if need be. Dealing with an image seq isn't exactly a big deal...).
Ideally, I'd just like to get this XAVC thing sorted, though.
