PLUGE Black Level Test – Below Black and Above Black
YouTube re-encodes video and may normalize levels - the DOWNLOADED file carries the exact code values and range flags; use it for the real measurement. Set brightness so the Y=4 bar disappears but Y=20 stays just visible.

Frequently asked questions
- Why does this need the downloaded file, not just YouTube?
- YouTube re-encodes and can normalize signal levels, so below-black and range-sensitive patterns are only accurate in the original downloaded file.
- What's a range mismatch look like?
- Crushed black detail, clipped whites, or a washed-out/over-contrasted image are typical signs of a full vs. limited range mismatch.
