Annoying Pixelating/Blocking After Encoding in Handbrake

[Reckoner]

Forgot to mention yesterday that I confirmed that decoding using DXVA decoder with Intel doesn't fix the pixelation issue, only AMD.

After tweaking the settings I finally hit my preferred balance of size and quality. Picture quality is excellent. Only thing I don't like is there's a slight jerking during scenes where the camera slowly pans. Not sure what I can do about it. Might be the deinterlacing or the 29.97 fps. Anyway it's not as noticeable as the pixels so I guess I'll put up with it.

Yay AMD. Nice to know another option exists

I think Doctor Who was 25p => 29.97i (59.94 fields/s) . I think it was 3:2:3:2:2 pulldown . 25p content will never be perfectly smooth on a 59.94Hz display

It is and marked as 100% interlaced streamwise, I did tivtc and tdecimate with cycle=6 for smooth 24.975fps video. Playing with
Qtgmc and srestore=25 feed into dgpulldown for mobile DVD purposes now to see how it looks. Worked ok on Torchwood and the white queen on DVD which is also encoded the same way but different codec

Removing pulldown to make it 25p is probably the better way to go. Because some playback setups won't detect 3:2:3:2:2 cadence and will deinterlace resulting in loss or resolution and artifacts. But 25p content still won't play "perfectly smooth" on displays in North America either way. It will always be slightly jerky

[dannyboy48888]

Very true for device playback like a PC, roku, etc and using AVC straight 25p would be the way to go. Im more or less making a band aid for my region 1 dvd player. They're progressive scan and ignores the soft pulldown in my case. It chokes on region free pal disc though so thats what I do. Also mpc-hc ignores the pulldown on playback in my case and I can remove it again with dgpulldown ifbi really needed to

I am trying to encode my Doctor Who blu rays but am having a miserable time. I'm new to all this so hoping that someone can help. I've tried tons of different settings but it always comes out the same. There are these annoying pixels, most noticeably in the title sequence.I could post my handbrake settings but I've tried several different profiles and nothing works.

Here's the kicker...It occurs even when I play the original source mkv ripped from the blu ray in VLC but NOT in the Windows 10 video player. What's the deal with that? the source is 1080i VC-1. Deinterlacing in VLC is turned off. After encoding the pixelating is visible in any player. It's very noticeable and cringe inducing when watching on my TV via Plex so I can't ignore it. Anyone have any ideas? Screenshot posted below.

It looks like Noise or mild artifacts, it's due to how the Blu-Rays were mastered.

Not sure if HandBrake has a pure artifact removal filter. hqdn3d can remove the noise. Start at lowest settings and see if it's been removed. If not head to the next setting. You may also want to sharpen the picture slightly after using hqdn3d.

I did, There is noise in the picture for sure. The other seems to be banding artifacts.

Maybe Upload a sample sample so it can be analyzed?

Revan654, we already confirmed it is a decoding issue. It is a well-known issue with the libav/ffmpeg VC-1 decoders (well, until ffmpeg fixed it literally 4 days ago). OP confirmed it by testing against the DXVA decoder which didn't show the same artifacts. With Blu-Ray bitrates you don't have such extreme artifacts.
