Same (Constant) Bit Rate, Different Scene Complexity
I've been asked about that, but I couldn't figure it out the answer. Given two H.264 video streams with rather the same (constant) bitrate, but with different scene complexity: one video stream of a white wall and the other one with a lot of motion. Which one (if any) is going to consume more computing resources to be decoded?
The big difference is that scene with a lot of motion will be encoded at a far higher quantization level to compensate for the fixed amount of bandwidth. Unless the bit rate is set very high, you are likely to have artifacts / quality problems.
As for computing resources, I'd bet it be similar.
p.s. - please try to convince people not to use CBR. VBR with a cap is better.
