Zella
Freemium
Zella is an on-device screen recorder and video editor for Mac and iPhone. It records screen or camera footage, then supports AI-assisted polishing, captions, background removal, reframing, and export without an account or cloud upload.
Zellaとは？
Zella is an on-device screen recorder and video editor for Mac and iPhone. It captures screen or camera footage and provides tools for cutting, polishing, captioning, reframing, adding effects, and exporting finished videos. The iPhone app is a full touch editor, not only a viewer, and projects can be transferred to Mac as .zella packages.
The app is built around local processing: recording, editing, captions, background removal, voice polish, and export run on the device, including in airplane mode. No account is required and footage is not uploaded. Optional network-dependent functions include the AI Assistant, when used with a personal API key, and stock-footage retrieval for some Auto B-Roll workflows.
Zella Free is available indefinitely and includes unlimited recording, the full editor, AI features, and watermark-free exports up to two minutes at 1080p. Pro is a one-time purchase covering Mac and iPhone that removes the export length limit and adds higher-resolution, alpha-channel, frame-rate, bitrate, batch-aspect, template, and advanced editing options.
Zellaでできること
Auto-Polish and Make it Viral
Auto-Polish can cut silences and filler words, add captions and emphasis zooms, clean voice audio, and duck music. Make it Viral adds a broader one-tap pass with pacing, transitions, sound effects, music, and word-pop captions.
Captions, callouts, and background removal
Generate captions on-device, apply caption presets and callouts, remove backgrounds without a green screen, and add a webcam bubble or one of 40 built-in scenes.
AI-assisted editing and Auto B-Roll
The AI Assistant accepts typed editing instructions, while Auto B-Roll can create cutaways. The iPhone app supports a keyless on-device B-Roll mode; optional stock footage can be fetched from Pexels or Pixabay.
Reframing, effects, and audio tools
Reframe edits to 9:16, 1:1, or 16:9 with face tracking, and use colour looks, transitions, sound effects, voice changers, LUT import, intensity controls, and music that ducks under speech.
Pro export and advanced controls
Pro adds unlimited export length, 4K output and 8K on Mac, transparent-background export, 60 fps, custom bitrate, multi-aspect export queuing, saved templates, keyframes with Bezier curves, luma scopes, masks, speed ramps, and Beat Sync.
利用シーン
“Screen tutorials and walkthroughs”
Capture a Mac window, region, or full screen, remove pauses, add captions and punch-ins, then export a concise explanation for sharing or instruction.
“Short-form social clips”
Use face-aware reframing for vertical, square, or widescreen output and apply caption, pacing, transition, and sound treatments for Reels, Shorts, or similar platform formats.
“Phone-first field recording”
Record and edit directly on iPhone when away from a desk. The local workflow supports airplane-mode editing, and a project can later be exported to Mac for larger-screen finishing.
“Transparent product and motion assets”
Remove a subject from its background and, with Pro, export an alpha-channel file for placing the isolated clip over another layer in a separate editor or composition.
“Long-form lessons and client deliverables”
Use Pro when a recording exceeds the Free export limit or requires 4K, 8K on Mac, 60 fps, a custom bitrate, or multiple aspect-ratio outputs from one edit.
よくある質問
Is Zella free to use?
Yes. Zella Free is available forever rather than as a trial. It includes unlimited recording, the complete editor and AI features, and watermark-free exports up to two minutes at up to 1080p. New installs also provide seven days of the complete Pro feature set without a card or account.
Does Zella upload recordings to the cloud?
No. Recording, editing, captions, background removal, voice polish, and export run on the Mac or iPhone, and the app can work in airplane mode. The AI Assistant and some stock-footage workflows can use the network when enabled; the Assistant sends the typed prompt using the user's own API key, not the video.
Can a project move between iPhone and Mac?
Yes. Export the project package from iPhone and open it on Mac. Clips, cuts, captions, titles, callouts, and effects are carried across in the `.zella` project package.
What does the one-time Pro purchase add?
Pro removes the two-minute export cap and adds 4K export, 8K export on Mac, transparent-background export, 60 fps, custom bitrate, a multi-aspect export queue, saved templates, and the advanced depth toolset. One purchase unlocks the Mac and iPhone versions together.
What formats and aspect ratios can Zella export?
The editor can export MP4, MOV, GIF, and M4A, and can reframe projects to 9:16, 1:1, or 16:9 with face tracking. Free exports are limited to two minutes and 1080p; Pro adds higher-resolution and other output controls.
