Whammy is a lightweight JavaScript encoder for generating WebM video directly in the browser. It exploits the relationship between WebP image frames and the VP8 codec used by WebM. Developers can add canvas elements, canvas contexts, or encoded image data as individual video frames. Frame rate can be defined globally, while individual frame durations can also be specified.

jsgif is a pure JavaScript library for encoding still or animated GIF files from HTML5 graphics. It is a JavaScript port of the GIFEncoder portion of the earlier as3gif project. Developers can feed the encoder an HTML canvas context or raw image-data-style pixel arrays. Animated output can be configured with custom frame delays and repeat counts. Encoded data can be converted to Base64 for inline display, transferred to a server, or saved directly as a GIF file. The implementation includes GIF encoding, LZW compression, NeuQuant color quantization, and helper utilities needed to generate GIFs entirely on the client side.
