How to use this tool

  1. Compare ideal planar YUV 4:4:4, 4:2:2 and 4:2:0 payloads for one frame.
  2. Set frame width, frame height, bits per sample in the indicated units.
  3. Calculate and compare yuv 4:4:4 payload, yuv 4:2:2 payload, yuv 4:2:0 payload.

Try this example

{
  "w": 1920,
  "h": 1080,
  "bits": 8
}

Accuracy and scope

Packed theoretical payload only; excludes row padding, metadata, alpha and container overhead.
