Corner Pin with Scaling into layer
I am doing a screen replacement on a laptop computer. The shot was tracked in Mocha and corner pin data brought into After Effects. Next up I am animating the scale of both the video and the corner pin layer together so that the camera pushes fully into the screen.
Now when I push into the computer, the computer starting a mid distance away, the replaced video (layer with corner pin data) gets extremely pixelated because of the nature of the effect. The corner pin effect stretches the layer small to fit the screen and when it gets scaled up it doesn’t have the resolution to play with anymore.
Any Ideas how to make this work so I end with a high resolution screen?

Thanks for the tip. I’m Mastering at HD (1080p). I tried the technique and found out from the camera zoom in I would need about 3 times the resolution, so I sent a scaled up video file (5760 x 3240) to Mocha and then used that corner pin data on a solid of the same size. Then scaling the footage down by 33.33 % to match the 1080p footage it had just the right resolution for the camera zoom in.
The only thing with this method… tracking footage that size can be a real time killer.
