Hello! Just checking in to revive this topic. I’m still stumped. After Effects needs a “Mask Offset” property.
To refresh, I have an animated mask (with a keyframe on EVERY frame). I want to duplicate it and slide the duplicate mask a few pixels to the right, but not loose any of the animation already on the mask.
I’m beginning to think this is not possible without moving the mask on every keyframe.

I’m not exactly clear about your question. It says you’re having a problem getting a good matte from the footage you have (I can help with that!) but then asks about turning a shot black and white while leaving the screen green (Which confuses me a bit).
If you are having trouble getting a good key, let’s deal with that. Once you have the FG character extracted, you can do anything with the color on it’s, or any other layer.
Can you give us more detail or a description of the final effect you want?

One other option, if you haven’t shot already, is to shoot your actor Green (or Blue) screen and then paint your earbuds and wire the opposite color (blue or green). Pull a separate mask for the wire and composite it that way.
There will surely be some challenges with keying something that thin, especially in fast motion, but a little roto is better than a lot! I’d also stay away from HDV formats if possible. A nice DV50 4:2:2 signal or better keys quite nicely (if you have the budget!).
Good luck!

Very strange. Is your shutter angle (in your Comp settings) set really high? That would explain the smear, but not the flickering. It might be worth re-doing since it’s a simple animation just to see if the problem persists. Maybe even in a new Comp. I’d also try another image in it’s place just to see if it’s the image or a Project issue.
Let us know, we can troubleshoot deeper.

Thanks for the idea. Unfortunately, I am using this for the Reshape effect which only uses masks from the layer the effect is applied to. I want to roto people, duplicate the mask, shift it 10 – 12 pixels and warp it over into the 2nd mask using Reshape. I’m faking 3D on old 2D footage, I’ll let you know how it works!
I have done this before (maybe I slid the mask on every keyframe!?). Since I’m using Autotrace there is a keyframe on every frame. I’m not doing that! If you know of any tricks I’m forgetting, I’d love to hear them. At this point, I think an expression (Beyond my level) might be the only way. Maybe an Expression Control setup the right way.
I’ll post over there as well!
Thanks, any other wisdom is much appreciated!

If it’s finished examples you’re looking for, I have several on You Tube. Check out “The New Shool of NOVA” and any of the “Burke & Herbert” ads. Those were done entirely on green screen. My Demo has me composited into some movie scenes, all of my footage was greenscreen as well.
All three (or six, if you count all the Burke & Herbert spots) of these examples have shadows. Some added in post, some actually from the original footage.

Hope this helps!

We shoot a lot of 24p greenscreen footage at DV50 4:2:2. It keys with almost one click in keylight. Are you looking for some samples to download?

I’m going to try that just for the learning. I turns out that the expression you gave me with 3 instances is the perfect solution because the medal counts should go into double digits. 3 double digit instances of the Numbers effect with your expression works perfectly!
Thanks for the revised expression. I’ll put it to good use.

I was hoping to do it with one 3 digit instance of the numbers effect but after seeing your expression, I see how that probably doesn’t work. I’ll make an instance for each number and your expression should work perfectly!
Thanks, Chris
