I'm trying to create something like the marvel intro, where some (moving) faces have video footage as a texture. Like a screen basically.

I'm currently trying this by creating a group with the faces and loading these as an AOV via Karma.
Then track this scene later and apply the footage manually to these faces in After Effects.

Is there a better way to do this? How would you approach this scene?

I think doing the footage in comp is more flexible.

Here is how I would approach it.
first separate or create masks for the prims you want to use for the footage, then create uvs for each prim. We will later use the uvs as a color channel to fit the footage onto.

Here I have created a bunch of planes with perfect uv's and added a random value that I will later use when selecting my footage.

after that i set up the aov's with the uv and idx. These will be embedded channels, but you can write them out separatly

in a copnet I use the idx channel that I created in the aov to randomize the (images/image sequences). I use texture samplers and give them the uv info from my uv aov and then you get the images displayed on the planes. No tracking needed

You can then render this out for use in after fx as a layer. The nice thing about this is that you can change the footage at any stage and its quick to render.
hope this helps
