Large blocky artifacts when rendering with pixel motion blur, none when previewing in AE

[rgames]

I have an image sequence that I'm rendering with pixel motion blur and it looks fine when I preview in AE but I get large, black blocky artifacts in the renders.  If I disable the motion blur there are no artifacts in the render.  The behavior is the same in 2023 and 2024 versions of both AE and media encoder.  I have also tried both hardware and software renders.

Any suggestions?

Thanks

That's not ideal.

Could you share screenshots that show the problem? Also, a screenshot of the export settings? Are you using the After Effects render queue or Media Encoder to export?

Let us know, we're here to help.
