Wash a clip in one color. The tint is blended over every frame with the blend mode you choose, from a subtle warm cast to a strong single-color look.
Color, mode, and strength
Tint Color sets the overlay. Blend Mode decides how it combines with the picture, and Strength how much of it is applied. Soft Light at 30% to 50% gives a gentle grade; Color at 100% gives a monochrome in the tint’s hue.
Tint versus duotone
A tint keeps the clip’s own tonal range and adds color over it. For a look where shadows and highlights are rebuilt from two chosen colors, use the duotone video effect.
