Two Lanes of AI Editing: Mechanical Cleanup and Narrative Assembly

9 October 2026 · RenderBob team

AI editing tools split into cleanup that follows story decisions and assembly that proposes them. A third question, local or cloud processing, now cuts across both.

Trade coverage of AI editing often lumps the tools together. Two lanes serve different moments in an edit, and a third question cuts across both: where the processing runs.

Mechanical cleanup

CineD described the AutoCut plugin for Premiere Pro and DaVinci Resolve as the cleanup that happens after the story decisions. Silence removal, take selection, captions, and profanity bleeping, with padding so a cut keeps a little air, and J-cuts or L-cuts to smooth the join. It supports recent Premiere versions and Resolve 18.6 and 19, including Resolve's free edition. On talking-head and interview footage, a module like that can reduce a multi-hour recording to a watchable assembly. The decisions are objective: a pause, a filler word, the cleanest take.

Narrative assembly

Story judgement lives here: what leads, what follows, what gets cut for pace. The rough-cut tools covered in the suggestive-editing piece work in this lane, as do speaker-aware multicam cutters. One Resolve-focused guide describes a podcast tool that reads speaker diarisation and cuts between camera angles according to who is talking, a job Resolve's native multicam tools leave to the editor. The vendor says it turns hours of multicam cutting into minutes. Test that claim on your own material.

Where the processing runs

Footage is often confidential, and uploading hours of rushes is a real objection. NodeCut, a rough-cut plugin for Premiere and Resolve, positions itself as fully local. It runs Whisper large-v3 for word-level timestamps, scores each angle for motion, faces, emotion, and sharpness, and assembles the cut on the user's GPU. Its maker claims about 25 minutes to rough-cut a five-hour, three-camera wedding on an RTX 3090, with nothing uploaded. Those are vendor figures. The design choice is the point: offline processing removes the confidentiality objection.

Which lane to trust

Use cleanup liberally. Its errors are easy to spot and undo. Use narrative assembly as a proposal, then apply your own judgement. Keep processing local when the footage is sensitive or the connection is poor. Use a cloud service when speed or model quality is worth the exposure.

Check the handoff

Confirm that the tool exports an open interchange format, and that markers, metadata, and bin structure survive the trip. Resolve's Cut page is often recommended for a fast review of an imported assembly, because it suits quick refinement better than the full Edit page. Ask what decision the tool is making. If the decision is objective, automate it on the machine that already holds the footage. If it is the story, treat the output as a suggestion. RenderBob is built for that split on generative shots: the project stays with the studio, local when the machine can carry the preview, cloud when the shot needs a heavier model.
