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.

Available filter presets:

ValueDescription
boostPunchy and vivid — richer color, higher contrast. Good for social and marketing clips.
contrastCrisper tonal separation — adds definition to flat footage.
darkenLowers exposure — useful for dialing back a hot or overexposed shot.
lightenRaises exposure — opens up dim or underexposed footage.
mutedDesaturated, moody, with crushed shadows — a documentary or cinematic look.
greyscale (also grayscale)Fully desaturated black-and-white output.
negativeInverts 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.
