29.97 PROGRESSIVE to 23.98
Hi Experts.
I am trying to take a spot that is 1080p 29.97 and cpnvert it to 23.98. I have read numerous recipes to do this in After Effects. Does anybody know if the source footage must be interlaced? Can this be done with progressive footage natively in After Effects?
Any info would be great. Thank you.

You can do it with progressive footage. The resulting quality will depend largely on what method you use to change the frame rate. Re:Vision FX’s Twixtor as well as The Foundry’s Kronos are both top notch retiming plug-ins.
If you don’t have access to those then you’re stuck with frame blending or Timewarp.
I’ll also mention that retiming techniques that use pixel motion vectors to generate frames can be either amazing or horrible depending on the amount and type of motion. For a 29.97 to 23.976 conversion I’d recommend comparing the results of a simple Frame Mix frame blending, or even no frame blending (every 5th frame is dropped… I often prefer this personally but your client may demand otherwise), to the more advanced pixel motion vector techniques (Timewarp, Twixtor & Kronos).

[Chris Wright] ” AE has kronos built in, renamed as timewarp.”
My understanding is that Timewarp is a much older engine than the current version of Kronos.

from the trial, as far as I can remember, it added a little preset for different dv color types and gpu acceleration.
