the background and the lock source is now in front of it. Thus you are now keying out the lock source
colors to reveal the input source behind it.
Note that this is different to simply swapping over the input and lock sources as that would affect the final
output resolution – see examples below:

You will see that the Swap between foreground and background has no effect on the output resolution as
this is always set by the Lock source.
The Min/Max parameters are used to select what range of Y (luminance/grey-scale) values are made
transparent within the selected window/lock source. To key out part of an image, start with the max value
and increase it until the required lighter parts within the window/lock source disappear. Then adjust the
min level to bring back any darker parts of the image.
The Y Key softness option removes noise from the keyed image, generally at the edges. Adjust as required
to make the edges of the key as sharp or as soft as desired. The noise is where the analog to digital
process (A/D conversion) may not sample a 50% brightness as being exactly 50% i.e. sometimes 49% and
sometimes 51%. Increasing the softness value will broaden the range of keyed colors so that the keying of
images varies depending on how close a color is to the keyed-out range.
The Y Key invert changes the keying characteristics with respect to what colors of the foreground image
you wish to ‘key out’.
Setting it to Off will cause the color range that’s defined to be removed - remove the desired colors.
Setting it to On will cause the color range that’s defined to be kept - key out all other colors.
The descriptions above behave identically on the remaining U Key Invert & V Key Invert component
versions. However they are directed at the U/B-Y (blue) color component and V/R-Y (red) color
components respectively. Adjustment and effects are the same as explained above for Y Key Invert
(brightness/grey-scale).
