Is 8GB of RAM enough for serious 4K ProRes video editing?

No, 8GB is not enough for serious 4K ProRes video editing. It works for light work, but you’ll hit performance issues like stuttering timeline scrubbing, long exports, and frequent beachballs with layers or effects. The MacBook Air also lacks active cooling, causing thermal throttling under sustained loads. For real video editing, get 16GB or step up to a MacBook Pro.
