  1. Hi.

    I read that hvec(x265) codec can give the same quality
    video compare to avc(x264)codec,while using 40%-50% less
    bitrate for second(smaller file size).
    So,if i would like to convert a video file with x265 codec to x264 codec
    and i would like to save the quality(or minimize the loss),should i double the bitrate/sec while i make the conversion to x264?

    Thanks.

  2. For a good x264 quality encode with CRF range 18-21. The bitrate is determined by the encoder.

  3. Thanks,ProWo.
    Yes,i am familiar with the CRF option,
    But what if the software doesn't have the CRF parameter option?
    and there is only the option to choose bitrate/sec value,
    should i double the bitrate value?maybe triple it?when i convert x265
    to x264?

  4. Use my clever Ffmpeg-GUI. It has the CRF Setting for the h264 encoder.
