Lumae is a free native macOS app for recording software demos and annotating screenshots. Each page below covers one part of it: what it does, how it decides, and the numbers behind it.

## Camera and motion

What the virtual camera does with a flat recording.

- [Automatic zoom](https://lumae.app/features/automatic-zoom.md): Clicks become camera moves, with the timing worked out for you.
- [Smooth cursor](https://lumae.app/features/smooth-cursor.md): The pointer, redrawn: smoothed, tilted, and pressed on every click.
- [Motion blur](https://lumae.app/features/motion-blur.md): Camera moves sampled across a shutter, the way a lens does it.

## Look and sound

The frame around the picture, and everything you hear.

- [Backgrounds and framing](https://lumae.app/features/backgrounds.md): Backdrops, padding, and corners measured from the window itself.
- [Captions](https://lumae.app/features/captions.md): Transcribed on your Mac, broken into lines a person can read.
- [Voiceover and music](https://lumae.app/features/voiceover.md): Narrate over the finished cut. The mix gets out of the way.

## Capture and output

Getting the picture in, and getting the file out.

- [Screen recording](https://lumae.app/features/screen-recording.md): Display, window or area, with the metadata the editor needs.
- [Screenshots](https://lumae.app/features/screenshots.md): Capture and annotate, with every mark still editable later.
- [Export](https://lumae.app/features/export.md): MP4, MOV, ProRes and GIF, from the renderer the preview uses.
