Separating the YUV channels?
on Apr 18, 2015 at 6:09:17 pm

I'm trying to demonstrate the different YUV channels in HD video but I can't quite find an effect in AE that lets me see just the Y, U or V channels separately. Is there something in there that would allow me to do this?

That may be tough. AE works in RGB. Now, there used to be a way to get it to work in YUV, but it wasn't widely used. I don't know you can still do it.

(I am not at my editing system right now, so I am doing this from memory.)

You can probably accomplish it by setting up 3 effects - I'd use an adjustment layer:

Channel Combiner1 set RGB to YUV

Curves Effects
RGB= don't use
Red = Y
Green = U
Blue = V

Channel Combiner2 set YUV to RGB

Another idea, Synthetic Aperture Color Finesse is a color correction tool that comes with AE. It can manipulate colors using YCbCr notation. which is for most purposes the same as YUV.

Great thinking of Jim! Simple as that - but I did not manage to get to it. Thanks!
