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.
