Zoom, speed and trim

`Zoom <element> [scale]`	Zooms onto the element and stays locked on it, following it if it moves, until the next `Zoom`. Without a scale it is fitted with room around it, at most 4×.
`Zoom @x,y [scale]`	Onto a point, 2× unless a scale is given.
`Zoom cursor [scale]`	Follows the cursor, smoothed over 0.3 s so it glides rather than jitters.
`Zoom off`	Back to the whole window.
`Zoom@<easing>,<duration> …`	This zoom's own move: `Zoom@ease-out #list`, `Zoom@600ms off`, `Zoom@smooth,1s cursor`.

Scales run from 1× to 8×. The zoomed region keeps the window's shape and stays inside it. reel says so when an element nearly fills the window, so fitting it hardly zooms.

Moves take ZoomDuration (400 ms) with ZoomEasing (ease-in-out) unless the reel or the zoom says otherwise:

Easing	Moves
`linear`	At an even pace.
`ease-in`, `ease-out`, `ease-in-out`	Starting slow, ending slow, or both.
`smooth`	Half a sine: gentle at both ends.
`snap`	Not at all: it jumps.

A zoom on an element is found while recording, so changing which element needs a new take; its scale and easing change with a render. Zooms on a point or the cursor are render-only.

Speed

Speed 4x
Click "Export"
Wait "Done"
Speed off

The stretch plays faster, above 1× up to 16×. Narration keeps its own pace, and the app's sound is left out of a sped-up stretch, where it would only be noise.

Skip the setup, cut the dull parts

Whatever happens between Hide and Show is left out of every video: the way to get the app or the page ready before the demo starts, such as accepting a cookie banner or opening the right screen.

The recording runs throughout and the cut is made when rendering, so moving a Show needs no new recording. A Hide with no Show runs to the end. A cut that would split a narrated line is refused.

Speed and trims take effect at the end of the action before them, like captions, and change with a render. Everything timed (captions, narration, ducking, zooms) moves with the cut; .reel/<reel>/edit.json says what was kept and how fast.

In a reel of tracks, Speed and Hide … Show are the director's, over every track; a track can't have its own. See Reels together.
