10. Going deeper: Lenses, Find frames & Find moments

Three tools take a finished analysis further. All run from an open report.

Lenses

A lens re-examines a video through a specialized point of view — for example, a software-demo lens or a film/cinematography lens — instead of the general report. Use a lens when the standard report is too general for what you're studying.

How to run one:

Open a report. In the lenses area, pick a suggested lens (or browse all).
Clicking a lens opens the Configure step so you can confirm the cost first. It then runs as a new lens on that video, billed like a re-analysis (each pass re-processes the video — see Chapter 6).
Completed lenses appear in a Lenses section below the main analysis. Each lens — and each depth you run it at — is its own card, so a Standard and a Deep run of the same lens both show separately.

Once you've run more than one lens, Compare lenses lays them side by side so you can see how different viewpoints read the same video, and Download PDF saves that comparison as one document.

Find frames

Find frames pulls out the exact still frames (images) where something happens — every screen of an app being demoed, each time a product appears, or every scene change.

How to use it:

Open a report and choose Find frames.
Describe what you're looking for — for example, "every distinct screen of the app being demoed."
The AI proposes the matching points. For an uploaded video, Contentine then extracts the actual frames in your browser into a gallery you can download individually, export as a set (ZIP), or lay out as a contact sheet. For a YouTube-URL video, it gives you the timestamps and links to those points rather than extracting the images.

Find moments

Find moments is the companion to Find frames, but instead of single images it finds time ranges — the clips where something is said or shown — and lets you download each clip. Use it when you want the moment itself, not just a frame: every time a feature is mentioned, each product shot, the exact segment where a topic comes up.

How to use it:

Open a report and switch to Find moments.
Choose Match in — this tells the search where to look:
Audio + visual — spoken words, sounds, and what's on screen.
Audio only — spoken words and distinct sounds.
Visual only — on-screen text, graphics, and action.
Describe what you want — for example, "every time pricing is discussed" or "each shot of the product on a table."
Contentine searches the analysis your video already has (its transcript and scene descriptions) rather than re-watching the video, so results come back in seconds and cost about a cent — and it still works even after the temporary upload copy has expired.
Each result is a card for one range. Preview plays just that slice of your file (nothing is re-uploaded — the preview reads your local copy), and you can nudge the Start and End a second at a time before you export.

Downloading clips: For an uploaded video, each card has a Download button that cuts that clip on your device and saves it as an MP4 — nothing is uploaded to do this. Tick several cards and use Download selected to get them all as one ZIP. Because the clip begins at the nearest keyframe, it may start a moment (up to a second or two) before your chosen start — a short, expected lead-in. For a YouTube-URL video, Contentine gives you deep links and an in-page preview of each range rather than cutting a file.

Videos with no sound. If your file has no audio track, Find moments searches on-screen (visual) only — the Audio options are turned off and a note says so. This is deliberate: with no audio there is nothing to match spoken words against, and it keeps results honest.

Both tools are billed like a re-analysis and run in the same mode the video was analyzed in — Quick Mode if it was analyzed in Quick Mode, or My Keys with the same Gemini key. Searching the saved analysis (the usual path) is billed at the cheaper text rate.

A couple of practical notes:

Cutting or previewing clips uses private in-browser file storage. Incognito / Private windows block that storage, so the search and previews still work but Download is disabled — open the site in a normal window to save clips. The app tells you when this is the case.
If you reopen a report later on the same computer, your on-device copy (kept up to 48 hours) lets frames and clips keep working without re-selecting the file. On a different computer, or after that window, just re-select the same file when asked — it's verified against a fingerprint so you can't accidentally pick the wrong video.
