Choose one picture or an overview
Capture a frame saves an instant you select. Create contact sheet produces one image containing several thumbnails distributed across the recording. The first keeps the frame’s resolution; the second helps catalog and review recordings without playing every file in full. Neither operation creates an animation or includes sound inside the exported picture. For a representative thumbnail, watch the video first and avoid a blurred instant or transition. For an overview, remember that sampling can miss brief actions, even when the resulting grid looks complete and is easy to read.
Enter the capture time and format
Enter a timestamp within the video’s duration, using seconds or minutes and seconds. You do not need to pause the player manually at exactly that instant: the tool locates the corresponding frame. Entering the exact end adjusts the request to the last available frame because no picture exists after it. PNG, JPG and WebP are available when the browser can export them. PNG preserves exported pixels without another lossy compression step, but it does not remove defects already present in the source video. Check both the downloaded picture’s dimensions and its detail.
Define the thumbnail grid
A contact sheet supports four to twenty-four pictures and two to four columns. The tool divides the recording into equal-duration intervals and captures each interval’s midpoint. It does not automatically detect scenes, people or important moments. Each thumbnail fits a 320 by 180 pixel cell and retains its aspect ratio with bars when necessary. A timestamp below identifies its position in the recording. Portrait footage can leave empty space at the sides of the thumbnail; this lets the full frame remain visible instead of cropping it to fill a landscape cell.

Check dimensions and timestamps
Six pictures in three columns produce two rows and a PNG measuring 1008 by 448 pixels, including margins and labels. In an approximately six-second recording, the captures fall around 0.5, 1.5, 2.5, 3.5, 4.5 and 5.5 seconds. When actual duration includes a fraction, those timestamps vary slightly. Adding pictures samples more instants while keeping individual thumbnail size fixed, so the overall sheet grows. Check that labels remain readable at the size where you intend to share or insert the overview, especially if a receiving application automatically reduces large images.
Review what each picture reveals
Before sharing a capture or contact sheet, enlarge it and inspect every cell. It may reveal notifications, names, documents or people you did not notice during playback. The sheet does not hide those details or replace a content review. If a capture fails near a scene change, try another timestamp; for an unsupported file, inspect its properties and browser capabilities first. Saving happens when you select Download. Keep the original video and record which source file belongs to the sheet so its timestamps retain a clear reference when you return to the material later.
A sheet with six recognizable instants
Download sample-video.mp4 and open Create contact sheet. Enter 6 pictures and select 3 columns. Process, inspect the grid and download the PNG. Visible colors and frame numbers help show that the pictures came from different positions in the recording. Next, open Capture a frame with the same video, enter 2.5 seconds and select PNG to save an independent full-resolution picture. Keep both results available for comparison.

The sheet measures 1008 by 448 pixels and has two rows. The independent capture keeps the sample video’s 480 by 270 pixels.
Read timestamps from left to right and top to bottom. Inspect the saved image outside the browser and check that the individual capture corresponds to the requested instant. For your own footage containing very brief scenes, increase sampling or choose captures manually; a uniform sheet does not guarantee coverage of every action.
