3 Things to Know About M3 vs M2 MacBook Air for 4K Video Editing
Regarding the MacBook Air: 1. M3 is faster for exports and heavy effects The M3 Air exports 4K timelines 20-30% faster than the M2 and handles timeline scrubbing with heavy plugins more smoothly. For simple talking-head edits or light color grading, the M2 is still perfectly fine.
M3 adds AV1 decode, but M2 already has ProRes acceleration The M3 gains hardware-accelerated AV1 decode and a faster media engine, which speeds up transcoding for h.265 and ProRes RAW. The M2 already supports ProRes acceleration, so the gap is small for most codecs.
Both throttle under sustained loads — get a Pro if you edit all day Neither Air has a fan, so both slow down during long 4K exports or heavy rendering. If you edit 4K video professionally or all day, buy a MacBook Pro instead.
