SHIP TO EVERY PLATFORM
Cut it once. Every platform gets the version it wants.
Re-cropping the same video for TikTok, then the feed, then YouTube is the single most wasteful hour in a creator week. Vision face detection keeps you in frame when the ratio changes, platform presets are already the right pixels, and the export renders on hardware you own with nobody else in the queue in front of you.
Zella for Mac is coming to the Mac App Store, and Zella for iPhone is coming to the App Store. One Pro purchase covers both. See the mobile app →
WHAT CHANGES FOR YOU
- 01
Stop re-editing for each platform
Face-detection auto-track keeps you centred when the aspect ratio changes, so a 9:16 crop does not take the top of your head off. One edit becomes every ratio the brief asked for.
- 02
No render queue in front of you
Export runs on your own hardware. Nothing is uploaded first, nothing waits behind another customer, and a deadline at 2am is not somebody else’s capacity problem.
- 03
The right pixels without looking them up
TikTok, Reels and Shorts at 1080x1920, YouTube at 1920x1080, Instagram at 1080x1350, and GIF with your captions and zooms baked in. Free exports are watermark-free at up to 1080p, permanently.
ON BOTH PLATFORMS
What it does on each device.
On Mac
Export MP4, MOV, GIF or M4A at 1080p free and 4K with Pro, plus 8K on the Mac alone. Pro adds ProRes 4444 with alpha, 60 fps, a custom bitrate and the multi-aspect queue, which renders 9:16, 1:1 and 16:9 from one edit in a single action instead of three separate exports. Versioned snapshots and autosave recovery sit under all of it.
Get it at launch →On iPhone
Make Vertical reframes to 9:16 around your face in one tap, and export runs on the phone itself with TikTok / Reels / Shorts / YouTube / Instagram presets. Pro adds 4K, 60 fps, a custom bitrate and transparent-background export (HEVC with alpha), plus the multi-aspect queue. Or hand the project to the Mac as a .zella file and finish on the big screen.
Everything the mobile app does →
Same project either way. Hand it across as a .zella file and the clips, cuts,
captions, titles, callouts and effects come with it.

WHEN THIS MEETS A PAID CEILING
This is the pillar Pro genuinely exists for. Free exports run up to 2 minutes at up to 1080p, watermark-free and forever. Pro lifts the length cap and adds 4K (8K on the Mac), transparent-background export, 60 fps, a custom bitrate and the multi-aspect queue.
Everything else is free forever: the complete editor, all the AI, unlimited recording, and watermark-free export up to 2 minutes at up to 1080p. 1080p is free permanently, and a free export is never stamped. Pro is $89 once and covers Mac and iPhone on a single purchase, and every new install runs the full Pro set for its first 7 days with no card and nothing to cancel. See pricing →
