Video contact sheet with grid and timecodes

About this video contact sheet with grid and timecodes

Create a local PNG video contact sheet with 2–6 rows and columns, optional file information and per-frame time labels; input under 1 GB Processes streaming audio and video buffers directly in the browser using HTML5 Media and Web Audio APIs with zero server uploads.

Audio and video decoding pipeline

The execution engine processes input tokens and applies transformations in the browser sandbox. Specifically, The video stays on this device. HTMLVideoElement seeks to duration × index / tile count. Canvas draws the decoded frames in row order with 16-pixel gutters, a time label in each bottom-right corner and an optional 96-pixel information header. PNG contains the composed image without audio.
