Sure it does work, although it doesn't seem the best solution for me: i must render the fileout node, then import it as a FileIn and only then be able to play with it.
I use the Retiming to achieve some "real" Motion blur, first i slow it down, then i speed it up again blending the frames. With this method i have to render in between.
I also like the effect of the weird warps Shake does when doing extreme adaptive time remaps: i wanted to be able to tweak the previous processes without re-rendering see how they work:
The thing is i'm having problems because the retiming processes different the color and alpha channels and the result is uncompositable... And i wanted to see what the changes along the tree do to the time remapping
Well, I was just wondering if there was a node to do propper time remaps, if the only place is the FileIn node i'll cope with it.
Cheers!
