Flickering issue when Motion Blur is turned on

Hi acopbg, adding to Rob's question, if the flicker only shows in preview but not in the rendered output, it's just AE dropping motion blur samples during preview to keep playback moving, which is normal and clearing the cache could help. Definitely worth rendering a short section first to confirm.

If it's also in the render, please share the following details:

1. What kind of layer has motion blur on it - footage, shape/text, or a precomp?

2. If it's footage, what is the source of it? Is it downloaded?

2. Your AE version and your system specifications (CPU, GPU, RAM).

Let us know.

Thanks,

Nishu
