This is the image to be added with the alpha channel. It is called “Fill”. |
|
|
(2) |
This is the image to be added to the “Fill” as the alpha channel. It is called “Key”. |
|
You can apply the clip to be the “Key” like a mask as the alpha channel of “Fill”. Overlay the created clip to an image to be the background to composite the clip.

[Alpha matte (invert)] Select this item when the clip selected as “Key” includes an alpha channel, and the alpha channel is inverted and applied to the alpha channel for “Fill”. [Luminance matte] Select this item when applying the luminance lever (0% to 100%) of the clip selected as “Key” is applied to the alpha channel for “Fill”. Luminance level 100% is transparency 100%. [Luminance matte (invert)] Select this item when applying the luminance lever (0% to 100%) of the clip selected as “Key” is applied to the alpha channel for “Fill”. Luminance level 0% is transparency 100%. |
