What it does
- Live 9:16 preview with captions at the bottom of the frame.
- Timeline for captions, images and three audio tracks.
- Images fit the frame over a blurred copy, so nothing is cropped.
- Trim, split, fade and mix audio, with undo and redo.
- Quick half-size draft export, or a full 1080×1920 export.
How to install
- Mac: open the downloaded .dmg and drag KathaCut to Applications. The first time, right-click the app and choose Open, then Open again. macOS shows a warning because the app is not signed with an Apple developer certificate.
- Windows: run the installer. If SmartScreen says it protected your PC, click More info, then Run anyway. The warning appears because the installer is not code-signed.
- In the app, choose File, then New Project, pick a folder, and pick your narration audio. To continue earlier work, choose Open Project.
Good to know
- The Mac build is for Apple silicon only. Intel Macs are not supported yet.
- Each project is a normal folder holding your audio, captions (.srt), image list and exported video. Back it up like any folder.
- Add your own images, or use ones you have the right to use. KathaCut does not supply any.
Privacy
KathaCut works offline. It has no accounts, analytics or ads, and your audio, images and videos stay in the project folder you choose.
