I rendered an iPhone with a black screen in Blender and then animated it so the camera pans in a circle around the iPhone. I exported this as an AVI file. Then I took my real iPhone and took a screen recording. How can I use After Effects to overlay the black screen from the fake rendered iPhone with this recording while the AVI video pans the camera around the rendered phone? I am new to After Effects.
You can use your screen recording as a video texture in Blender.
This would then require no tracking / layering in After Effects. Here's an example of how to go about this.
