There are four Key Color Transitions included in Video Edit Magic. All involve varying the colors in an image. All four of the Key Color Transitions are explained here.
Chroma Key makes all areas of one video track, that are a particular color, transparent, letting the other video track "show through". It is used, for instance, to let actors perform in front of a "blue screen" and then add a separately-filmed background to the scene later.
To use a chroma key color :
The chroma key does not vary over time. Use this transition to overlay one image over the other.

Non Red Key makes blue and green colors of the overlay images / videos transparent. To use a Non Red Key Transition:
The non red key does not interpolate (vary) over time. This transition can also be used to compose overlays and to superimpose videos.
Luminance Key is keying based on luminosity of an image. As the transition takes place, one image appears to "fade" into another, as if one image is transparent and another shows through it. To use a Luminance Key Transition:
Use Luminance key to achieve fade in and fade out effects. Luminance key is very effective when its operation is inverted. It's also very useful if you want to add a watermark to your movies.

Hue of an image is the color produced by visible light. The common color terms such as green, red or orange refer to hue. The key type alters hue over time. To use a hue key :
Use hue key to achieve fade in and fade out effects with image burns. Hue key is also very effective when its operation is inverted.
Once the desired key type is selected and configured, click ‘Ok’ to apply the key type to the transition.
Normally, for Key Color Transitions, the picture from Video Track 2 appears in front of Video Track 1 (and the transition makes Video 1 visible). If you Swap Video Tracks For This Transition, Video 1 will be in front of Video 2.
