Video filters

Video filters transform a VideoStream. The common ones read as methods; the whole FFmpeg catalog is reachable as Filter classes through apply().

$clip = Media::open('in.mp4')->videoStream();

$clip->scale(1280, 720)->drawText(text: 'DRAFT', x: 40, y: 40);   // friendly methods
$clip->apply(new \FFmpeg\Filter\Vignette());                      // any video filter

Parameters can be a number, an FFmpeg expression, or a per-frame closure that receives the filter’s own variables — see the Architecture. To check a graph as you build it, VideoStream::frameAt() renders a single frame.

A few you’ll reach for

Method	FFmpeg	Does
scale()	scale	Resize / convert pixel format
crop()	crop	Crop to a region
overlay()	overlay	Composite one stream over another
drawText()	drawtext	Burn text onto frames
vignette()	vignette	Darken toward the edges

Full recipes are in the Examples. A page per filter follows.
