Kamua

Adapting a horizontal video for TikTok or Instagram Reels means cropping it, reformatting it and making sure the subject stays in frame — tedious work done manually. Kamua automates this with AI-powered smart cropping.

Kamua is a browser-based tool for reformatting and repurposing videos for social media. The main feature is AutoCrop: the AI analyzes the video and, when you convert it from landscape to portrait or square, automatically follows the main subject to keep it in frame, without you having to intervene on every frame. AutoCut identifies the highlights and cuts less interesting parts, speeding up the creation of short clips from a long video. Kamua also generates automatic captions that adapt to the new format. The platform supports output formats for all major social platforms — TikTok, Instagram Reels and Stories, YouTube Shorts, Snapchat, Pinterest — and shows a real-time preview of how the video will look on each platform before rendering. The browser-based approach eliminates the need to download software or move files between devices. It's particularly useful for those who need to repurpose existing content across different platforms without having to re-edit everything from scratch.

For creators, social media managers and marketers who produce video content and need to reformat it for multiple social platforms without wasting time on repetitive manual editing.

Kamua offers a free plan with a limited number of monthly renders and access to basic features. Paid plans increase available render volume, export resolution and advanced AI features; exact terms should be verified on the site, as the structure may vary. It's a relatively accessible tool for those managing moderate video reformatting volumes.
