What Patchy Keying
Uneven chroma-key masks leaving holey or translucent patches.

How to Spot Patchy Keying

• Flecked transparency in green-screen areas.
• Visible background bleed through hair/fine details.

Causes of Patchy Keying

• Poorly lit key background with hotspots.
• Keyer tolerance set too low or high.

Fixes for Patchy Keying

• Re-light your key: even, soft lights on backdrop.
• Tweak clip black/white and clip roll-off in your keyer.
• Use garbage mattes and edge-refinement tools (choke, soften, spill suppression).
