VidMix - Color Replace
The Slick VidMix Color Replacer compositor lets you add an alpha channel to a video based on color. This is often used for "Blue Screen" composition.

+ =

If the color you are replacing is white or black , you should use the BrightnessReplacer instead. Also, if the color is extremely dark or light, try the Brighteness replacer.

  • Closeness adjusts proximity to the color selected.
  • Choke extends the edge of the selected pixels.
  • Smoothing softens the edge.
Tip: Hold the Option key to change the cursor to the eye dropper to get a color from the overlay movie.
