What is a video contact sheet (storyboard grid)?

A video contact sheet is a single image displaying a grid of evenly-spaced thumbnail frames captured across a video, accompanied by timestamps and file metadata.

How do I generate a video contact sheet?

Upload your video, select grid layout (e.g. 3x3, 4x4, or 5x5 frames), choose background color and timestamp overlay options, and click 'Generate Contact Sheet'.

Why are contact sheets useful for video editors and archivists?

Contact sheets provide an instant visual summary of long recordings, movies, or rushes without opening video editing software.

Can I display technical metadata (resolution, duration, codec) in the header?

Yes. The generated sheet includes a clean header showing filename, file size, dimensions, duration, and frame rate.

What image formats can I export the contact sheet in?

Download as high-resolution PNG or JPG image.

Is the video analyzed locally on my device?

Yes. All frame capture and grid compositing execute 100% client-side in browser memory.
