Effects are one ordered list. The same list sits on a clip, on a track, or on the whole timeline, and it runs in the order you write it.
On a track, the list covers every clip on it. On the timeline, it covers the finished video, which is where one grade for the whole edit belongs.
Every entry takes an optional start and length, in seconds or as a percent of what it sits on, so an effect can run for part of a clip. Numeric parameters take keyframes, so they can move while it runs.
There are 34 effects, for picture and for sound, each with its own parameters in real units. The full list, with a rendered before and after for each one, is the effects reference. The groups: Two of them read a file, which is fetched and checked like any clip source: lut takes a .cube grade, and mask takes a picture that decides what of the clip shows.
An effect that changes the picture is refused on a clip that has none, and one that changes the sound is refused on a silent clip, so a mistake is a 400 rather than a render that ignores it. Text and shapes draw their own outline and shadow, so outline and dropShadow are refused on them.

​
Colour

One color effect carries brightness, contrast, saturation, temperature and the rest, so there is one place to correct a picture rather than nine overlapping filters. look applies a promoted recipe in one word, and lut takes a .cube file you supply.

Stylise

glitch, pixelate, posterize, rgbShift, scanLines, sketch, trails and shake. Used for a beat or a scene change rather than a whole video.

Layers

chromaKey removes a solid background, mask cuts a clip to a shape, blurRegion hides a face or a plate, and outline and dropShadow edge a layer that has transparency.

Anything the engine can do

{ "type": "engine" } reaches the rest of the render engine by its own names, for the case a promoted effect does not cover. Every service and property is checked before the job starts, so a typo is a 400 and not a failed render.
An engine entry that duplicates a promoted effect is refused, so there is one way to ask for each thing. The names come from the engine and can change when it is upgraded, which the promoted names never do. Every effect and every parameter is in the effect reference. Sound effects are on Audio levels and effects.
