Thank you for the quick reply and explanation.
The black & white source is 4:2:0. Advanced Video Coding, Main@L3.1 CABAC / 4 Ref Frames. In that case, would that need more data going to color?
Does going 4x3 to 16x9 letterbox same resolution (just adding black bars to the left and right) require more data or is it negligible, because the black bars doesn't require much data?
So for a 1000kbps 4:2:0 640x480 25fps to 1920x1080 letterbox 50fps mp4, a 5000kbps would be a good target? (using average bitrate 1st pass)
Final question. Does setting the target at 5000kbps require more or less computation time than 2500kbps or its the same?
