Ben —
Just wanted to share the process that’s (sort of) working for me:
I’m doing the initial time remapping in Premiere, creating keyframes right on the clip. The clips I’m using are 4K proxies that I rendered out of DaVinci from R3D files. However, I actually need to utilize the R3D files’ entire 6K for reframing within my master 1080 comp (DaVinci tops out at 4K output).
So I imported the original R3D files that I’m using into Premiere, and edited them onto the layer above my proxy file — matching up the first frame, and then extending it out all the way to the end of the R3D file’s duration (way past where my proxy file ends). Then I copied the time remapping info from the proxy file and pasted that attribute onto the R3D file. The clips (Proxy and R3D) now have matching durations and time remapping data.
At this point, I alt-drag that R3D file up a layer to make a copy, and send THAT (along with VO for reference) to After Effects via Dynamic Link.
Once in After Effects, that native 6K R3D file appears in a new 1080 comp, and Premiere’s Time Remapping data shows up as Time Remap Keyframes. I can then open up Position and Scale properties, and animate them to taste, taking full advantage of the full 6K raster within the 1080 comp, while also being able to tweak the time remapping.
It’s not perfect, but it’s what I’m moving ahead with.
