Contact Sheet Maker

About

Contact Sheet Maker turns the video you are watching in Chrome into a clean, timestamped image grid.

Click the toolbar icon on a page with a video, choose how many seconds to wait between frames, and generate. The extension samples the video, creates one or more contact sheets, downloads the images, and restores playback afterward.

Use it to review videos faster, archive visual notes, or give an AI assistant a compact image summary of a clip.

Features:

One simple control: sample every N seconds.
Live estimate for frame count and number of sheets.
Aspect-aware layouts for landscape and portrait videos.
Automatic multi-sheet downloads for longer videos.
Timestamp labels on every frame.
Local browser processing with no accounts, analytics, or uploads.
Known limits:

DRM or protected video may not be capturable.
Live streams and non-seekable media may not provide a full timeline.
Some embedded iframe videos may be limited by Chrome or site restrictions.
If direct frame capture is blocked, visible-tab fallback may include on-page overlays.
