Tool ID: video-contact-sheet-maker. Requested language: cu. Description language: en. Complete guide translation: no; untranslated sections use English.

## Overview (en)

The video contact sheet maker samples frames evenly from a chosen part of a video and tiles them into a single PNG grid. Set the start time, the sampling duration, 1 to 8 columns and rows, and a thumbnail width from 80 to 640 pixels. Thumbnails are separated by white 4-pixel padding, and timestamp labels are not embedded.

## Supported tasks (en)

Samples a selected interval into a tiled PNG. Longer source duration does not need to be processed if the interval is bounded. Timestamp labels are not embedded.

## Steps (en)

1. Choose a source file. If the tool accepts multiple files, arrange them in the order you want.
2. Adjust the basic settings, then open Advanced mode for export and fine-tuning options. Custom settings stay active when the panel is closed.
3. Run video contact sheet maker, review the output, then use the available copy or download controls.

## Questions (en)

### How are frames chosen for the video contact sheet?

The tool samples at a rate of columns times rows divided by the sampling duration. A 4 by 3 grid over 10 seconds takes 12 frames, about 1.2 per second, starting at your Start time.

### Can I make a contact sheet from only part of a long video?

Yes. Set Start to where sampling should begin and Sampling duration to the length of the section, up to 3600 seconds. Only that interval needs to be processed, not the whole file.

### Does the contact sheet show timestamps on each thumbnail?

No. Frames are tiled without text labels. You can work out a thumbnail's time from the start time plus its position in the grid multiplied by the sampling interval, which is the duration divided by the number of tiles.
