Question-Avid 59.94 fps to 24 fps or 23.976 fps in After Effects
Hi:
I’m trying to figure out the best way to render out Quicktimes for seamless import into an Avid. We’ve done this a few times before for a local client, but there were some issues.
Now we’re doing motion graphics and 3D animations for an out-of-town client working on an Avid of some sort. At this point I don’t know what flavor. I don’t have direct communication with the editor; I have to use the producer as a go-between. Not ideal, but that’s the situation.
They sent us some 1920×1080 59.94 h.264 edited clips as placeholders a few weeks ago. The Quicktimes are of a host in front of a greenscreen. When I bring those 59.94 clips into a 24P comp in After Effects I get full, unduplicated frames to build my motion graphics around.
Today they sent us twenty seconds of the fullrez footage to test. I’d told the producer to tell the editor to export using Same as Source. The Quicktime I got was 1280×720, 59.94fps, AvidDNxHD codec, Trillions of Colors (according to AE.)
So what would one normally render out for import into the Avid? Should I be working in AE with a 24 fps comp or a 23.976 fps comp? I was having an issue with 23.976 precomps showing only every other frame in the master comp (also 23.976) unless I checked “Preserve framerate when nested or in render queue.” Comps and precomps at 24fps didn’t exhibit that issue.
Does the Avid have timeline settings for 24 fps and 23.976 fps? Should I find out what the editor is using? Or will his timeline say 59.94?
Then, do I render out at 24 or 23.976 or 59.94? In the past, when I worked with interlaced HD (29.97?), I removed the pulldown to make it 23.976 and rendered it at that rate to re-import into the Avid, and that seemed to work. Originally I’d added the pulldown back in AE to make it 29.97 again, but the resulting Quicktime exhibited some weird field artifacts. The issue I ran into when rendering my 24 fps comp out at 59.94 is that I’d get extraneous frames popping up after what was supposed to be a cut.
Brain. Hurting. Make stop, please.

being what you received was 1280×720, 59.94fps, I’d go with that but of course your gonna have to get that from the horse’s mouth.
You’ll render lower field first.
