Knock out your background with the tap of a button! Transport your actor to a new location with ease! Create astonishing before and after effects. It’s all possible with the Chroma Key tool in KineMaster! The Chroma Key tool can take a little bit of time to figure out. Learn how to use it here.
Chroma Key is available when you tap an image or video layer. Then, tap the Chroma Key button in the Options Panel that opens on the right side of the screen.
Enable – Toggles the Chroma Key tool On and Off.
Foreground Cutoff – The threshold above which everything is considered part of the foreground. This determines what is preserved.
Background Cutoff – The threshold below which everything is considered part of the background. This determines what is removed based on the Key Color.
Key Color – The color that is removed from the screen. You can select between preset colors or select your own.
Detail Curve – Adjusts the blending levels between the foreground and background cutoff. Generally, curves that pull towards the lower-right corner will remove more of the background color at the expense of a sharper edge on the mask. This only needs to be adjusted if it’s not possible to get satisfactory blending on the edges.
Show Mask – Shows the level of transparency for the selected item. Areas in white are fully transparent, while areas in black will be visible on screen.
KineMaster Tip: Chroma Key Best Practices
The KineMaster Chroma Key tool is very powerful. Using the following tips will get you even better results.
1. Turn on mask mode.
2. Drag the foreground slider down until the foreground is pure white with no holes.
3. Drag the background slider up until the background is pure black with no noise.
The further apart the Background and Foreground Cutoff sliders are, the softer the edge of the mask, but the more of the Key Color you can see on the fringe.
You can achieve the best results selecting a Key Color that is a supersaturated version of the background color. This ensures the key color is far away (in the UV color plane) from other colors, so you don’t get accidental drop-outs of other similar colors. KineMaster will automatically select a supersaturated version of the most common color in the scene as the key color. Usually this is correct, and you don’t need to change it. Note that black and white are not advised as key colors.
