Proxies at exact integer fractions of the master scale back to full-res perfectly with no rounding drift, so your offline edit conforms cleanly to the online. UHD (3840ร—2160) halves to 1920ร—1080 โ€” full HD proxies that cut smoothly on a laptop. Always keep proxy dimensions even for the proxy codec.
