Pixelation when exporting

[Chloe Georghiou]

Hi all,

I have been exporting a range of different videos recently and I am having a problem in all of them where in some parts of the videos there is some weird pixelation. See here:

I have tried:

• Overlaying a different clip at the same time codes
• Exporting on 3 different computers 
• Creating a new project file
• My Premiere is also on the most up to date version, I have tried exporting on different versions of 2021

But with all of these things that I have tried, they still export with this error.

If anyone knows the cause of this and have any solutions, it would be much appreciated.

Thanks a lot.

Forgot to add, this would probably be useful:

The pixelation isn't occuring at the same place in time right? It is occuring in diffrent areas of content? Maybe areas that have a lot of detail?

It seems you are rendering a 4K sequence at VBR, 1 pass at 17mbps.

Try changing it to 2 pass, and using a higher bitrate. For example google recommends 35-45 mbps for 4K YouTube uploads.

If you are using transparency effects you could also turn on the "Render at maximum Depth" switch in Basic Video settings.

Try turning off Hardware encoding.
