Export

A finished file, not a render queue.

Up to 4K at 30 or 60 FPS, MP4 or MOV, H.264 or HEVC — plus a playable MP4 written the moment you stop.

The problem

You stop recording and what you have is not a file yet. It is a project, in a format nothing opens, waiting on an export you will run twice because the first one had the wrong aspect ratio.

What happens instead

A ready-to-play .mp4 appears beside the project as soon as the take finishes — the captured video copied without re-encoding, with microphone and system audio mixed into one track. When you want the styled version, Export renders the canvas, Smart Zoom, camera and cursor.

In detail

What export actually does

Something to send immediately

The remuxed MP4 costs no second encode, follows the project through Duplicate and Move to Trash, and Projects → Show MP4 in Finder reveals it.

Social presets

Landscape and portrait canvases sized for where the clip is actually going, without re-cutting the edit to get there.

Codec by intent

H.264 where compatibility matters, HEVC where file size does, in an MP4 or a MOV container.

Nothing half-written

Export writes a temporary file and publishes the finished one only after it has succeeded, so a failed render never replaces a good file.

FAQ

Questions about export

What is the MP4 that appears next to my project?

The captured video copied without re-encoding, with microphone and system audio mixed into one track, so you can play or share a take straight away. Canvas, Smart Zoom, camera and cursor styling are rendered by Export instead, which also writes the constant frame rate that video editors expect.

Can I skip the instant copy?

Yes. Skip it from the progress panel when you only want the edited version, and create one later for an older recording from Projects → Save Ready-to-Play MP4.

Record the next one properly

Install it, hit ⌥⌘R, and watch a take that would normally cost you an evening in a timeline come out finished.
