Video Filter
video-filter
Applies a named color filter preset to the video output.
video-filter accepts a preset name as a string. Presets are curated color grades that combine brightness, contrast, saturation, and tone curve adjustments into a single named effect.

| Value | Description |
|---|---|
boost | Punchy and vivid — richer color, higher contrast. Good for social and marketing clips. |
contrast | Crisper tonal separation — adds definition to flat footage. |
darken | Lowers exposure — useful for dialing back a hot or overexposed shot. |
lighten | Raises exposure — opens up dim or underexposed footage. |
muted | Desaturated, moody, with crushed shadows — a documentary or cinematic look. |
greyscale (also grayscale) | Fully desaturated black-and-white output. |
negative | Inverts all color values — photo-negative effect. |
A preset is a baseline you can override. Any explicit video-brightness, video-contrast, video-saturation, or video-gamma values you pass replace that channel of the preset — so video-filter=boost&video-saturation=10 takes the boost look but tones the saturation back down.
Filters are applied in the GPU color grading pipeline before encoding.
