Hi!  :) 

My first post here after a decade of lurking.  :D

I'm finally getting around to editing something I shot 12 years ago!  :o  It's stereo 3D, and I used two Canon EOS 550Ds which were rigged side by side. Editing is proving to be a challenge...

I'd like to separate the 59.9fps up/down videos into two video streams. Ideally I'd do this within After Effects, but I can't figure out how. So far:

Import original up/down footage and interpolate as 50fps (I've always intended to slow it down a tad). Create two compositions. Give one a one-frame offset. Change compositions to 25fps. Both comps Look great - one up and one down.

Now, I could blend these two using AE's HDR Compander, but there's a temporal offset of 1/100th between the two exposures, so anything moving has a ghost. The only fix I can think of is rendering one of the 25fps compositions as a series of tiffs, and then reimport it as an image stream. I would then halve the speed of the footage using Time Stretch. AE would generate the missing frames. From there I'd extract those in-between frames as a fresh 25fps comp that would be in sync with the footage from the other camera.

All of that is quite straightforward, and I can create a template to repeat the process for each shot. Straightforward EXCEPT the cumbersome step of exporting tiffs to later have to reimport them. Does anyone here know of way to avoid this?

Am I missing something?

BTW I've taken a look at Switch, and it doesn't import .mov files.

Cheers!  ;)
