How to use it
- Choose a supported short SDR video or generate the synthetic example.
- Choose the number of frames, columns and optional short title.
- Create the contact sheet, inspect the frame labels and download the checked PNG.
Example: 12 frames in three columns form four rows. A requested position between video frames is labelled with the timestamp of the actual decoded frame.
Details & limits
Video up to 50 MiB / 60 seconds, SDR, one video track, maximum 1,920 px per side / 2.07 MP. 6–16 frames in 2–4 columns, each fitting 320 × 180 px. PNG up to 12 MiB. Codec support depends on the browser; audio is not processed.
Is the PNG a complete summary of every scene in the video?
No. Uniformly spaced frames can miss brief events. Use the frame extractor for a particular moment. The PNG is reopened and compared pixel by pixel before download; this verifies the saved image, not the completeness of its content.
