A contact sheet samples frames from across a video and lays them out as one grid image, usually with timestamps. It is how you see the shape of a recording at a glance — for reviewing footage, cataloguing an archive, documenting a shoot, or giving someone a preview of a long video without making them watch it.

Grid size and sampling

The grid controls both detail and legibility. A 4×4 sheet of sixteen large thumbnails works for a short clip where you want to see what is in each shot; a 6×8 sheet of forty-eight small ones works for a long recording where you want structure rather than detail. Even sampling across the full duration is the sensible default and is what makes the sheet a fair summary. Do not go so dense that individual thumbnails become unreadable — a sheet nobody can read is worse than a shorter video.

Timestamps make it useful

Without timestamps a contact sheet is a mood board; with them it is an index. Being able to point at a thumbnail and know it is at 14:22 turns the sheet into a navigation aid for editors, reviewers and archivists — someone can scan the grid, find the moment they want and jump straight to it. That is the whole reason contact sheets survived from film contact printing into video work, and it is why they are still standard in media archives.

Questions, answered

What is a contact sheet used for?

Reviewing and cataloguing footage. It shows the whole video as one image so you can find scenes, judge coverage, or give someone a preview without making them scrub through the file.

How many thumbnails should the grid have?

Around sixteen for a short clip where detail matters, up to forty-eight or so for a long recording where you want overall structure. Past that, thumbnails become too small to read.

Are timestamps included?

Yes, and they are what make the sheet genuinely useful — each thumbnail can be traced back to its exact point in the video.

JPG or PNG for the sheet?

JPG for sharing and emailing, since the file is much smaller. PNG when the sheet includes fine text or will be printed and you want the timestamps perfectly crisp.

Can I choose which moments are sampled?

You can set the range and the grid, and frames are sampled evenly across it. Narrowing the range concentrates the sampling on the section you care about.
