Edit screen recordings with zoom, captions and export
The cursor track, keystrokes and camera are kept as separate data, not baked into the frames. That means you can style each one, or switch it off, after recording. Your edits are saved automatically.
The editor has four parts. The toolbar holds the annotation tools and keyframe controls. The preview sits in the middle, with a timeline below it. The left rail has one page per feature.
Playback
Section titled “Playback”| Action | Shortcut |
|---|---|
| Play / pause | Space |
| Step one frame | ← / → |
| Go to start / end | Home / End |
| Loop playback | Loop button in the transport |
Trim, cut and crop
Section titled “Trim, cut and crop”The timeline has lanes for ZOOM, CAMERA, WEBCAM, VIDEO and AUDIO.
- Drag the trim handles at either end of the timeline to set the start and end.
- To remove a middle section, move the playhead and press ⌘K (cut at the playhead). Select the unwanted clip or gap and press Delete.
- Press S for split mode. One click divides a zoom or camera block into two halves with identical settings.
- Press C for crop mode. Esc leaves split or crop mode.
⌘-click adds a clip to the selection, and ⌥-drag moves without snapping. ⌘-scroll zooms the timeline.
Rail pages
Section titled “Rail pages”A dot on a page means the feature is on. A page greys out when the recording has no data for it. For example, Keystrokes is unavailable if no keystrokes were recorded.
| Page | What it controls |
|---|---|
| Layout | Stage behind the recording: fill, padding, corners, shadow, border |
| Color | A look for the whole frame: presets, exposure, contrast, warmth, grain, vignette |
| 3D | Tilt the recording in perspective; add moves on the CAMERA lane, or scenes that span the whole recording |
| Zoom | Auto-zoom on clicks, and the zoom selected on the timeline |
| Mouse Pointer | Size, highlight, click effect (None, Ripple, Ring, Both), motion blur |
| Webcam | The camera bubble: corner, size (S/M/L), circle or square shape, opacity, feed crop |
| Keystrokes | Key overlay size and position (Left, Center, Right) |
| Captions | On-device speech-to-text, burned in as karaoke-style captions |
| Audio | Microphone and system audio gain, ducking, and the Master limiter (on by default) |
| Visualizer | Bars, a circle or a wave that move with the sound (unavailable when the video has no sound) |
| Annotation | The selected annotation, or the tool you’re about to draw with |
| Title | Presets, in/out animation, layout and hold time for a selected text annotation |
| Overview | Presets, and a summary of which features are on |
Add a zoom
Section titled “Add a zoom”Press Z to add a zoom clip at the playhead, or drag on the ZOOM lane. In the Zoom page, set Focus to Follow cursor or Manual, then adjust Scale, Ease in, Ease out and Pan.
Generate captions
Section titled “Generate captions”Open Captions and click Generate captions. You can pick the transcription language first, or leave it on auto. Style the captions with Size, Position, Outline, Highlight, Box and Font. Use Edit text to fix the wording.
Add a visualizer
Section titled “Add a visualizer”Open Visualizer and turn on Show Visualizer. Choose a style:
- Bars: rounded bars that rise with the sound
- Circle: spokes around a ring, with an optional picture from your library in the middle (Picture → Choose…)
- Wave: the sound’s wave as a glowing line, like an oscilloscope
Each style follows the frequencies in the sound, not just its volume. Mirror reflects Bars and Circle, Size and Position set how big it is and how far down the frame it sits, and Color offers White, Black, Yellow, Green, Blue and Pink, or the gradients Sunset, Ocean, Neon and Ice. The background comes from Layout, and the frame shape from the canvas settings. The audio editor’s Video button makes a 9:16 video with a visualizer and captions already set up.
Edit by text in Script mode
Section titled “Edit by text in Script mode”Click Script at the end of the toolbar to edit the recording as text. The transcript replaces the preview and timeline, and each word sits under the stretch of sound that speaks it. Click Transcribe the first time.
- Delete cuts the selected words out of the video, picture and sound together.
- Shift-Delete mutes them and keeps the picture running.
- Typing over a word corrects the text, and the captions with it, without touching the footage. A correction works within one clip at a time.
- Clean Up finds filler words and repeats, and removes or mutes them in one step.
- Export in the Script header copies the text or saves it as .txt, .srt or .vtt.
Every edit is one undo step. While Script mode is showing, only the transport works; click Script again to get the timeline and the other tools back. The audio editor has the same Script mode, with more detail.
Annotations and masks
Section titled “Annotations and masks”The drawing tools work the same way as in the image editor: Select V, Box B, Circle O, Arrow A, Line L, Text T, Draw D, Highlight H, Cutout F and Redact R. Three mask methods are available on video: Redact, Blur and Pixelate. Masks are recalculated on every frame.
To animate an annotation, move the playhead and press K to add or remove a keyframe. Press , and . to jump to the previous or next keyframe. Jumping is the only reliable way to land exactly on an existing keyframe and edit it.
Export
Section titled “Export”Click Export in the top bar. The formats on offer depend on whether looping is on:
| Looping off | Looping on |

| MP4 (H.264) | Animated WebP (Recommended) |

- Include audio: available for video formats.
The dialog shows the duration and an estimated file size before you export.
