  1. Hi people, I was just wondering if anyone knows how to encode files in x265 but make the BD size much smaller while maintaining most of the quality like PSA encoders do. currently using Handbrake, one thing I learned was that if you turn sharpness to normal, you get a better quality output. Is there anything else I can do, tried de-noise but didn't see much difference. Oh and please do not recommend applications such as Hybrid because they are too complex for me. TIA!

  2. 1. Applying filters like denoise and sharpen does not 'maintain' quality but degrades it by changing from the original.
    If you choose to apply filters, sharpen increases file size (harder to compress), denoise can make files smaller. Use at your discretion.
    2. In the summary tab select 'mkv' as your format (it is a more flexible container than 'mp4')
    3. In the dimensions tab don't change anything (but you can leave autocrop)
    4. In the filters tab, turn off interlace detection and deinterlace to off if your source is progressive (Blu-Ray etc), leave it on if it's DVD
    5. In the video tab select H265 10 bit as your codec, or just h265 if you don't want 10 bit
    6. Select frame rate to be same as source
    7. Select constant framerate
    8. Select constant quality or bitrate. Bitrate lets you fix the exact size of your video.
    With constant quality you have to play around until you find the file size that suits you (Anywhere from 22 to 26 seems to work best).
    9. Set your encoder preset to 'medium' or slower. The slower you go, the better compression you will get.
    10. You can leave the encoder profile to 'main' and the leave the level at 4.0
    11. the audio and subtitle you can figure out.

    Steps 8-10 is what you play around with to adjust size and quality.
    Honestly if you want an exact file size, use bitrate and very slow preset.
    A bitrate calculator will help you determine what size you will get based on the length of your video.

    Thanks, I have another question. what if I have this file and don't know if its DVD or Blu-Ray, what should I do in step 4?

  4. Scan type: progressive
    Means your video is not detected as interlaced. Progressive means not interlaced basically. Most video you download or get from a digital source as a consumer will be progressive. DVDs or some TV sources may be interlaced.

    I'm using Handbrake and compressing at x265 10 bit; using the correct settings (I believe). I keep getting only audio (no video). Any insight would be appreciated. Thanks.

  7. I just have to ask, what is a "PSA encoder"?

  8. Just by the way: if you encode your x265 with 10bit, the result will not be played by many players or TV sets. Better encode with 8bit.

    lol what? this is h265 not h264

    PSA is a release group, not a encoder
