Hi my desktop (Nvidia 1060) plays youtube videos that are in HD very blocky; I think they are not being deinterlaced correctly - (4K is fine?).

 

I don't see an option on my GeForce control panel to adjust specific deinterlacing or anything like that.

 

Other video played in say VLC is fine ...

 

Any ideas? Can't say I've noticed this before today ... Hmm ...

Tried all different browsers? May be browser settings h/w optimisation related.

Just did that, all browsers are the same. Maybe it's the video that is blocky ... just that I didn't notice this before ...

Some YouTube stuff is pretty low-res, even if it is sent as HD. Pass the link around and see what others experience.

Ok here's an example https://www.youtube.com/watch?v=MGVmB6V-m78

 

Look for deinterlacing blocks

I see what you mean... 

 

 

The effect is much more distracting when watching it in the small YT window (pic above), but it is far less noticeable when you fullscreen it.

 

Fullscreen:

 

I'm pretty sure this just caused by the way they've recorded/edited the video.

Perfect image quality for me. MacBook Air - Safari

Quality for me is also fine. No artefacts. I don't know what is going on here, but it has to be something at your end.

 

I just downloaded it as MP4. Still looks fine on playback. I could send you a chunk just to see what happens when you run it through your media player.

What codec is YT using when playing the video for you? Right-click > stats for nerds > eigth line down, Mime Type: ..... codecs="___"

 

I just did some quick testing using different browsers (Chrome, Firefox, Edge and IE). I noticed that the first three all use the vp9 codec when playing youtube videos and when watching this video I see the weird distortion. Comparing this to IE which uses avc1.4d401e (H.264), I do not see the distortion.

 

I think that if your browser is using the 'VP9' codec then you'll probably see this anomaly.

 

If it says 'avc1.4d401e' (H.264) then it you'll likely not see this issue when viewing interlaced videos.

Thanks, will report back with the codec. Just wanted to know it's not my GPU :) 

 

Doesn't help my desktop has giant monitor

 

Played on the laptop again and I if I put my face to the screen I can see the artefacts :) [VP9 on laptop]

It's all the the voice videos. I picked this at random. Don't pay too much attention to the horrible singing though. This one is sings better. Suspect it's a half a hit wonder ...

I am running a Chrome-based browser on Windows and I don't see anything like either image. Resolution is better and no sign of artefacts. Is using VP9 codec.

How big is your screen? Can't see it easily on my 15.6" lappy from 2 feet away, easy to see it on desktop monitor. Maybe GPU has something to do with it too.
