Recording & auto-scroll

Scroll videos at exact pixels

Switch the capture type to Video and pick a style:

Hands-off

Plures drives. Auto-scroll glides the full page top to bottom over the clip at the speed you set (pixels per second), or record a static duration with the page held. Options:

Auto-scroll the page — on for the classic top-to- bottom scroll video, off for a fixed-frame recording.
Stop recording at page bottom — the take ends itself when the scroll completes.
Preview the run — run the scroll at the chosen speed without recording to check pacing first.
Hold — hold the page still mid-take while the video keeps recording.

Hands-off options: show cursor, auto-scroll, stop at page bottom, speed — Hands-off · the options

The capture window in Video mode: Hands-off selected, the Record control under the canvas — Video · Hands-off, auto-scroll on, record under the canvas

Auto-scroll drives the window's scroll. A page that scrolls inside an element instead, like some app shells and slide decks, is refused with that reason before the take starts; record it Hands-on.

Hands-on

You drive the page during recording — clicks, scrolling, menus, anything — directly in the canvas. Records a single viewport. Show cursor is optional. Start and stop with the record control under the canvas or ⌘⇧R.

Multi-viewport recording

With more than one viewport, record the primary take; the secondary viewports auto-record afterward, replaying your take at each size. Closing the capture window mid-recording stops and keeps the take — it finalizes and lands in the Library like any deliberately stopped recording.

With Hands-on selected, secondary viewports are struck through with a hint to switch to Hands-off — Hands-on records one viewport · Hands-off records them all

Trims and retimes

Recordings open in an editor with a trim timeline. A trimmed or retimed cut saves to the Library as a new item, or replaces the original: your choice. The source stays untouched when you save as new. An imported clip with sound keeps it through a trim and a speed change, and a phone clip keeps its rotation. To put a recording in a browser frame on a background with a headline, use Compose instead (see Compose); Compose exports video without sound.

Limits

Video records up to 4096 px a side. A larger viewport in the take is named and the recording does not start.
If the page stops responding mid-take, the recording stops there and what it caught lands in the Library. The page reloads once; a page that crashes again stays down with a message.
One capture at a time: Record waits while a screenshot run or a list of pages is going, and the other way around.

Recordings are H.264 MP4 at 30fps with wall-clock frame timestamps, so duration and pacing stay exact even when a very large viewport lowers the achieved frame rate (see frame rates).
