How to Find the Best Webinar Clips Without Rewatching the Whole Recording

The problem and who this is for

Webinars usually contain good teaching moments, but finding them by hand is miserable once the recording gets long. This workflow is for course creators, B2B marketers, coaches, consultants, webinar producers, and editors. The goal is to get to a short briefing that identifies the five best educational clip candidates and explains why each one is worth cutting with the fewest steps possible.

Prerequisites

Access to NotebookLM
A source file or capture workflow that matches the article
A place to save the final output, such as a Google Doc, notes app, spreadsheet, or editor brief
An editing or publishing workflow for your final short-form asset

How to capture or gather the source material

Export the webinar transcript from your webinar platform, meeting tool, or transcription software. Save it as TXT, DOCX, Google Doc, or PDF.
Export the slide deck to PDF if the webinar used slides. The slide deck adds context and helps the model understand where each section begins and ends.
If the webinar included Q and A, keep that section in the transcript but label it clearly. Some of the best clips often come from audience questions.
Add simple section headers if the transcript is one long wall of text. A few headers such as intro, case study, demo, or Q and A go a long way.

Step-by-step workflow

Upload the transcript and slide PDF into NotebookLM as separate sources.
Ask NotebookLM for the five strongest educational micro-clips, not the five most comprehensive summaries. A short clip should make one clear point quickly.
Tell NotebookLM to favor sections with clean openings, a concrete takeaway, and minimal dependence on the surrounding session.
Ask for a briefing output that lists the clip angle, cited source location, likely audience, and why the clip could work as a standalone asset.
Review the cited transcript passages and matching slides. Then cut only the clips that still feel clear when separated from the full webinar.

Tool-specific instructions

Primary tool: NotebookLM

NotebookLM is the best match because you can combine the transcript and slides in one grounded workspace and ask for clip ideas tied back to source citations.
Use the slide deck as context, not as the main source of truth. The transcript should still drive the actual clip selection.
A webinar clip usually works best when it teaches one thing well. Ask NotebookLM to reject sections that need too much context or setup.

Alternative: Claude

Claude is a good fallback if you already have a shortlist of source passages and want a cleaner editorial briefing for your team.
Drop the chosen excerpts plus the relevant slide text into a project, then ask Claude to rank them by clarity, novelty, and standalone value.

Alternative: Gemini

Gemini works well if your source material already lives in Google Drive and you want a fast file-based review workflow.
It is useful for pairing the transcript with supporting screenshots from the slide deck or speaker notes.

Quality checks

Each selected clip teaches one point cleanly.
At least some clips work even if the viewer never saw the slide deck.
The briefing uses cited source passages instead of general summaries.
The final five clips cover different subtopics or levels of depth.

Common failure modes and fixes

The chosen clips rely too heavily on slide visuals: Either pair them with the relevant slide in the asset package or reject them in favor of transcript-led moments.
The webinar has a slow opening: Tell NotebookLM to ignore the intro and begin selection after the first substantive teaching segment.
Q and A dominates the shortlist: Ask for a balanced mix of prepared teaching sections and audience-question clips.
The session is too broad: Split the transcript into sections first and run the workflow topic by topic.
