Ex: One guy say " my comanline this is the best setting for video quality when rip 720p to 576p
This code : "avs2yuv" "source.avs" -o - | "x264" --demuxer y4m --crf 1 --sar 3:2 --profile main --level 3.2 --ref 4 --bframes 3 --deblock -1:-1 --aq-strength 0.8 --vbv-bufsize 950 --vbv-maxrate 950 --direct auto --no-mbtree --partitions p8x8,b8x8,i8x8,i4x4 --keyint 100 --no-fast-pskip --no-dct-decimate --subme 7 --trellis 2 --psy-rd 1.0:0.0 --me umh --b-adapt 2 --no-scenecut --output "encode.mkv" - 2> "pass2.log"

Is there a reason you want to use main profile?  And why would you disable scenecut?  And what are you targeting with those vbv settings?

This guy has one thing right: --crf 1 will produce the highest quality without using lossless.

I think it would be better to throw all those setting out and start with: x264 INPUT -o OUTPUT --preset slow --tune film

Thank for help J_Darnley .

Yes, him choice main profile for playing stable lowend set top-box.
And no choice sceen cut because him get crapy frame by frame, no smooth when playing .

Target bitrate is 2Mbps for video+audio . I try your way but bitrate so high ~40Mbps .

I dont know value  "avs2yuv" "source.avs" -o - | "x264" --demuxer y4m use for about it . Can your help me know this values  .
