Katto: AI Video Clipper for Long Videos into Shorts
What is Katto
Katto is an AI video clipper that turns long videos into captioned vertical shorts. A YouTube or Twitch link, an uploaded file, or footage from Vimeo, Rumble, Zoom and Dailymotion goes in; scored 9:16 clips come out. It replaces the manual pass of finding strong moments, cutting them, reframing vertically and captioning them, returning a ranked shortlist instead of an empty timeline. It is built for creators who publish clips regularly — podcasters, streamers, sports and interview channels — and for developers or AI agents using its REST API or MCP server.
How does Katto work
A job starts when a video link or an uploaded MP4, MOV, WebM or MKV file of up to 90 minutes is submitted. Katto transcribes the footage, locates the moments worth keeping and scores each across hook, flow, value and trend. Miru then cuts and reframes the selected clips shot by shot and burns in word-timed captions. Ranked clips land in a dashboard editor for adjusting transcript, layout, caption style, hooks and B-roll, with unlimited re-renders. Each clip publishes to a connected platform, downloads as MP4 with SRT, or is fetched through the API. Billing counts the video, so a 90-minute episode uses the same monthly slot as a 10-minute one.
Benefits of Katto
Katto is judged on how clips are chosen, how the frame is handled and what the pricing costs. Selection returns a ranked list rather than a raw cut, each clip scored 0–100 on hook, flow, value and trend with a stated rationale. Reframing runs shot by shot and handles multi-speaker dialogue, gaming layouts and sports footage, not just a talking head. Pricing counts videos, so a 90-minute episode costs the same slot as a 10-minute one. Clipping, captioning and publishing to seven platforms sit in one tool, and the REST API, CLI and hosted MCP server are available on every plan, free included.

Core Features of Katto
Virality scoring
Each moment scores 0–100 across hook, flow, value and trend, with clips ranked and a rationale for the ranking.
Miru AI reframe
Reframing is decided shot by shot for 9:16, 4:5 or 1:1, following speakers, faces and action across multi-face, split-screen, gaming and no-speech modes.
Prompt-first selection
Clip selection follows a stated intent, topic, hook or audience angle instead of generic moment detection.
Text-based editing
Edits happen on the transcript: deleting or reordering text moves the cuts, and an editor exposes trim, reframe, caption, style and export controls.
Captions and dubbing
Captions cover 99 languages with word-level timing in 41; Creator adds dubbing in 19 languages at 20 clips a month.
Export and publishing
Clips publish to seven platforms in one click or on a calendar, in 9:16, 1:1, 4:5 and 16:9, with SRT caption export.
API, MCP server and CLI
A REST API with OpenAPI 3.1, signed webhooks and idempotency keys, a hosted MCP server with 16 tools, and an npm CLI share the plan's video quota.
Use Cases of Katto
- Podcasters: captioned clips per episode, with dubbing for a second audience.
- Streamers: reframe gameplay where the action sets the crop.
- Sports channels: hold the subject through fast shot changes.
- Interview producers: split-screen framing follows each speaker.
- Social media managers: publish one clip to seven platforms or schedule it.
- Developers: submit jobs through the REST API with webhooks and idempotency keys.
- Agent users: connect the hosted MCP server so an assistant clips as a tool call.
- Content teams: keep clips consistent with shared brand kits and caption presets.
