Recently I tried this app to create alpha-packed video directly:
https://github.com/SifuInTheShell/VRAutoMatte
At first it didn't work. Some extras failed to install and 8k videos won't start.
Then after I worked out the kinks:
- Don't use extras, just use "uv run vrautomatte".
- Changed the file "utils->ffmpeg.py" line 140 from
"-c:v", "h264_nvenc" to "-c:v", "hevc_nvenc"
It started working, and it's way better than I had thought. With my GPU 3090ti it churns out 4 to 5 fps for a video. It will take probably 8 hours for an one-hour 4k VR video, but it works.
So I want to share it to everyone here who needs to make Alpha pack video the easy way. VRAutoMatte will automatically recognize the people in the scene and convert it from EquRectangular into Fisheye then add alpha-red channel to it. Everything is done with just one click.
