Pixelation issues on animation
I've recently been having a problem when rendering animations from after effects through media encoder. When exporting as H264 with all the default settings (match source - high bitrate etc.), the image looks pixelated at random points during the animation. Initially I thought I just needed to crank up the bitrate but that still didn't work. I think that this is to do with my pc somehow because colleagues haven't had any issues exporting with my after effects projects. Any ideas?
I've attached my pc specs
