Video overview
Create a timestamped video contact sheet in your browser
A video contact sheet places multiple extracted frames into one chronological grid, making it easier to scan visible changes and locate moments before opening individual full-size JPEGs.
Contact sheet anatomy
Several moments, one chronological view
Diagram of the contact-sheet structure. It illustrates chronology and timestamp placement rather than pretending to be a generated demo result.
Useful for
Scan first, open individual frames second
- Scan a clip quickly before opening individual frames.
- Locate scene, layout, or UI changes in chronological order.
- Carry a compact visual overview into a broader evidence or AI workflow.
- Use the Full Evidence archive when you need the complete one-frame-per-second source trail.
How it is built
The overview stays tied to the local extraction workflow
- Choose a local video up to the current 180-second / 32 MiB production envelope.
- FrameDigest uses the browser's native decoder and canvas locally.
- Full Evidence preserves one frame per second, while the compact handoff separately scans visible changes at higher frequency.
- Timestamp labels keep contact-sheet tiles tied to the source timeline.
Limits
What a contact sheet is not
- A contact sheet is a visual overview, not a substitute for the original video.
- It does not represent spoken content while transcription is deferred.
- Selected media is processed locally for visual extraction and ZIP generation rather than uploaded to FrameDigest application servers.
FAQ
Contact-sheet questions
What is a video contact sheet?
It is a chronological grid of video frames that lets you scan multiple moments at once instead of opening each JPEG separately.
Where does FrameDigest include contact sheets?
Chronological contact sheets are part of Full Evidence, while compact visual sheets are used for automatic coverage in the AI Handoff.
Do contact sheets include timestamps?
Yes. FrameDigest keeps visual evidence tied to source time so the overview remains chronologically useful.
Does creating the contact sheet upload my video?
No. The selected source is decoded and processed locally in the browser.
