Title: Transcript-driven editing across synchronized multi-track video (Slides + Speaker)

Summary

Descript excels at transcript-driven editing, but currently assumes a single “truth” track.

Adding multi-track sync-aware editing (with optional tolerance-based correction) would significantly expand its usefulness for real-world recording scenarios without requiring users to fall back to external tools or destructive workflows.

Problem

A common workflow—especially with Zoom/Webinar recordings—is to have multiple synchronized tracks:

* Speaker video (with primary audio)

* Slides video (screen share)

* Sometimes gallery or secondary views

In Descript, transcript-driven editing works very well—but only for the track that the transcript is attached to (typically the speaker/audio track).

When using a sequence with multiple tracks:

* Script edits (deleting words/sentences) correctly cut the speaker track

* Secondary tracks (e.g., slides) do not receive the same cuts

* Result: tracks fall out of sync (slides lag behind speaker)

This makes it difficult to use Descript’s core strength (script-based editing) for common webinar/lecture workflows where multiple synchronized tracks must stay aligned.

----

Feature suggestion: Enable transcript-driven ripple edits across grouped synchronized tracks.

Proposed behavior: When editing a transcript:

* Allow users to “link” or “group” multiple tracks (e.g., Speaker + Slides)

* Apply script-based cuts to all linked tracks, not just the transcript source

Optional (advanced / ideal): After each edit:

* Check synchronization between tracks (e.g., via audio correlation or known offsets)

* If drift exceeds a threshold (e.g., 200–300 ms), prompt:

“Secondary track appears out of sync by X ms. Adjust?”

* Offer options:

* Shift track to match

* Keep as-is

This would unlock a very common use case:

* Lectures

* Webinars

* Oral histories

* Technical presentations

Users could:

* Edit via transcript (fast, intuitive)

* Maintain sync across slides and speaker

* Avoid flattening and extra steps

In short:

Bring Descript’s transcript-first editing model to multi-track workflows.
