Turn footage into one useful overview
A contact sheet arranges sampled video pictures in a grid. Use it to review a scene, compare takes, locate a moment or share a visual outline. It is a sampling aid rather than automatic scene detection. This tool exports a thumbnail sheet without inventing descriptions of the action.
Choose count or time interval
Select a compatible local video and set the start and exclusive end. Count sampling distributes N requests across that range. For a 12-second range and six pictures, the requested times are 0, 2, 4, 6, 8 and 10 seconds. Interval sampling gives a regular cadence. Neither mode promises exact source-frame indexes; a brief event can fall between samples.
Layout, timestamps and format
Choose 1–8 columns and a thumbnail width of 80–640 pixels. Pictures retain decoded source proportions. Optional timestamps appear in a label strip below each tile, leaving the subject unobscured. The sheet uses a white background and consistent gutters. JPG creates a convenient review file; PNG avoids additional lossy image compression. Check small text at actual size.
Limits and local processing
A job can request up to 120 pictures, subject to a 16-megapixel sheet and 8192-pixel side limit. Tall footage or a large grid may reach these limits first: use smaller thumbnails, fewer pictures or more columns. Rendering runs sequentially and can be cancelled; it does not retain a full-resolution gallery for every tile. Selected video is decoded locally without upload. Use the frame extractor to keep full-size stills.
