Summary
White noise artifacts appear around object edges (especially MetaHuman hair and fine details) only in the final render via Sequencer in Unreal Engine 5.5.2 on MacBook. The issue is not visible in the viewport. Adjusting anti-aliasing, Lumen settings, Nanite, and render formats hasn’t fully resolved the problem. Seeking advice from others who have encountered this on macOS with Metal rendering.
