Black Borders on a custom composition size
on Apr 24, 2018 at 10:36:49 am

Beginner in using After Effects, I'm currently using VPT7 software to do some projection mapping on a screens thats about 10ft x 3.25ft. I need to make animations that fit this size/ratio. I took the size 975 x 3000 which was the same ratio as the screen and high enough resolution to look clear on the screen

PROBLEM : When I Render out the animation from After effects using H264 compression I get two black bands on the left and right side which makes it hard for me to map the animation onto the screen that i'm trying to project on. Been trying different outputs and I have still got this problem.

H.264 has format requirements; it's not capable of encoding just any raster size.

Have you just assumed that deliverable resolution, or is it actually based on the projection system?
