Bright Speckling/Pixel Dots Appearing Around Phone Screen Mask

Hi everyone,

I’m getting bright speckled dots around the edges of a masked phone screen, but only after exporting. Inside After Effects it looks clean, but when I render it out, random white/green dots appear around the edges.

This happens even without using Mocha.. just a basic mask or tracked insert.

Has anyone seen this before or knows what causes it?

Thanks for writing in, danb68593733.

 

What version of After Effects are you using and what are your system specifications (CPU, GPU, RAM, OS version)? Outdated GPU driver is a common reason for such issues. Try updating it from the manufacturer's website.

Let me know.


Thanks,
Nishu
