Question / Help A lot of pixelation when using Quick Sync

[Brazen]

This only happens in OBS Studio, but works fine in OBS Classic. Whenever i record some footage using QuickSync in OBS Studio, there is a lot of pixelation, but if i record with OBS Classic, there is no pixelation, it's perfectly fine.

Many people have discouraged me from using classic, but this is hindering me from using Studio, so please, i need serious help.

10 mbps bitrate isn't really enough. Why aren't you using the recording presets in Simple output mode?

Okay then, i will try higher bitrate, what do you recommend? The reason i use Advanced is because i am an advanced user, in my opinion, i know a bit about streaming, encoding and recording but this is a problem that i just cannot solve.

I tried a higher bitrate but the problem still persists.
And again, this doesn't happen on OBS Classic.

Here's a video example of the pixelation :

What settings are you using that you needed Advanced mode for? Because that's not a pixelated stream, it's a corrupted one.

I am using Simple now. But how do i fix this issue? This doesn't happen with any other encoder in OBS Studio but this problem doesn't happen at all in OBS Classic.

It isn't corrupted. This the way the player playback the footage. Upload to YouTube original file and you'll see no corruption.

It must be in a bad way if VLC can't play it back.

Actually, it should playback but only continuously (without random access or by keyframe navigation).

The pixelation happens whenever i navigate to a another point in the video. The problem also happens if i import it into Sony Vegas. My videos are very heavily edited, so i there are a lot of cuts/jumpcuts here and it seems that Sony Vegas renders the pixelation.

Is there a way to fix this problem?

And if you remux video: main menu File>Remux Recordings?

Oh, thank you so so much. If you record in FLV and remux to MP4, the pixelation is gone. I can't thank you enough.
