- Satisfy VBR or CBR as per the need.
- Should allocate bits per frame depending on the complexity of the frame.
- Should adapt to the local complexity (at slice level , MB level).
- Maintain VBV to avoid any overflows or under flows.
- should take care of scene changes.
- use MVs or SAD or Var or Hist of Diff. or Diff of Hist as a measure of
complexity of the picture.
- the most important, visual quality after enc and dec should be good
and uniform all over the picture (this is subjective).
- and at the end seeing is beliving.(this is subjective).
hope this helps.
regards,
Vinayak.
