I’m hoping someone could shed some light as to what’s going on here.

I was able to get Handbrake installed on my Synology DS920+ NAS with Intel Quick Sync support. Using the exact same settings that I do on my local installation of Handbrake, the file size and end results appear vastly different.

I’ve tested different video files, but also the exact same one.

For example:

  • Original file H.264 1.3 GiB 18.1MBits/s bitrate
  • Handbrake local H.265 459 MiB 6.42 Mbits/s bitrate
  • Handbrake docker H.265 973 MiB 13.6 Mbits/s bitrate

My settings are:

  • Video encoder: H.265 (Intel QSV)
  • Framerate: Same as source
  • Variable framerate
  • Preset: Quality
  • Constant Quality: ICQ 32
  • Multi-pass encoding enabled.
  • Profile: Auto
  • Level: Auto
  • Filters: off
  • Dimensions: default (no resize, rescale, etc.)
  • Audio: AAC (avcodec) (mono)
  • Web optimized: Yes
  • Align A/V start: Yes
  • Passthrough Common Metadata: Yes

Is there an oversight that I’m missing that could explain this? I’d rather use the Docker version, since it doesn’t tie up my main laptop.

    Have you taken very verbose logs to see if there’s differences that stand out?

    Nope, but that could be a next step. I was hoping for an easy fix (like I did something wrong in the settings).

    Realistically, if this can’t be solved by using the built-in setting options, then it’s not worth the trouble to “fix” anything. It still works, so I’m glad to have the option.
