Smart cut rules ​

  • Category: Middleware

What it is ​

Does a talking rough cut (silence, retakes and so on) from word-level subtitles, and outputs the kept segments and sentence-level subtitles.

This node grew out of the related Lab tools: wires in a blueprint replace the step-by-step clicks in the Lab, which makes it easy to reuse and to hand to an agent.

Notes ​

  • Before writing back to the editing app, make sure LmBox is connected to the matching app (DaVinci Resolve / Premiere / After Effects and so on).
  • Always connect the kept segments when importing the video, or the whole clip may be imported.

Agents / MCP ​

For agents or developers (optional)
  • Once LmBox's open MCP is connected, the full ports and settings can be read from the catalog. This page is written for people, not around machine fields.
