Hello experts,
our team is working on a resolution expansion from 2560x1920 to 4096x3072. We have an encoder setting that provides an acceptable result for the 5Mpx case but now it seems to be a bottleneck for 12Mpx: compression ruins details. Setting target bitrate does not help. Even it is allowed up to level5.0's baseline limit (around 135Mbit/s) it is stuck at ~35Mb/s. See most of our encoder config below! How details could be quality encoded? We tried blocksize, qpI/qpP values, even region of interest. Any ideas?
