video contact sheet
Takes a video (up to 24 MB) and returns one JPEG with columns × rows frames taken at evenly spaced times across the running time, each tile labelled with its timestamp, and the list of those times. Tile width, grid size and JPEG quality are selectable. Useful for a quick visual overview, for choosing a thumbnail, or as a single image to hand to a vision model instead of a whole video. Runs locally with ffmpeg; nothing leaves this machine. Fixed price per call.
