Artifacts in Animation DVD MP4s

Post by Geardan »

I'm encoding from my DVDs and I notice that in busy animated scenes w/ a lot of movement I'm getting noticeable blurring/artifacts. It got better when I decreased the RF level (using Constant Quality), but I've turned it all the way down to 14 and am still getting things like seen in the screenshot below.

What am I missing? I'm pretty new to video stuff, so forgive me if I've overlooked something simple. According to the hover text, 14 RF is way lower than recommended.

An example of the artifacts.

Here are my settings:

Code: Select all

{
  "PresetList": [
    {
      "AlignAVStart": true,
      "AudioCopyMask": [
        "copy:ac3"

With the log, we can tell a lot about what handbrake found.

You could be looking at faithfully-recreated artifacts from the source; DVDs aren't perfect representations of the original video.
