Editing Proxy Resolution Calculator
Compute proxy raster sizes at 1/2, 1/4 and 1/8 of a master, rounded to codec-safe even dimensions for smooth offline editing.
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 (3840×2160) halves to 1920×1080 — full HD proxies that cut smoothly on a laptop. Always keep proxy dimensions even for the proxy codec.
