Hasta La Motion!

Hi, i’m working on xdcam hd422 1080i60, res 1920×1080 interlaced , the original rate is 29.97fps (rushes), it’s edited on FCP, and at the end will be transfer to film (non interlaced @24 fps) . So overall workflow will be converting from 1920×1080 @29.97fps interlaced to 1920×1080 @24fps progressive. The FX Compositing in-between that workflow will be done in Nuke.

The normal workflow is : from fcp 29.97fps, go to nuke @29.97 too, do the fx then send back to fcp @29.97, finally convert to dpx @24fps. How about converting 29.97 to 24 inside Nuke then do the effect @24fps so i will have fewer frames to work on , for example : rotoscoping 1 sec will have about 5 frames difference between these 29.97 and 24. Is it a good idea to do converting inside Nuke? also the footage is interlaced so i need to separate the fields. Any suggestion ? Does Nuke have good tools to deal with this conversion ( i found couple of plugins/tool , like fiedskit by Diogo etc) or need to do it outside Nuke ? i didn’t hear any good before version 6. Or any better workflow? there will be no change in resolution (HD 1920×1080), the blow up to film res will be done outside this workflow (optical) so no need to worry about it.

Thanx a lot.
