Do you have documentation on what Netflix is doing with Capped VBR (CVBR)?
Note that CRF itself IS scene-based encoding. There are other flavors of it, but the most basic is not to spend bits where they aren't needed.

I merely pointing at what i have read through their excellent blogs as well as general knowledge in this marked (i may be totally wrong on my assumptions, but thats why we are all here to learn
):
1. Using some kind of ML process to detect the scenes, separation
2. Encoding each scene seperatly with different encoding parameters (sweet spot), maybe different gop lengths also??
3. Use loops of CRF tests against a VMAF threshold to find the baseline for encoding with static/capped VBR.
