## What it is
canvid is a tiny dependency-free JavaScript library for playing relatively short videos on HTML canvas elements using image sprites instead of HTML5 video or animated GIFs. It offers playback controls like pause, reverse, and looping, but does not support audio.

## Use cases
- play short video clips on canvas without HTML5 video
- autoplay video on iOS where HTML5 video was restricted
- replace heavy animated GIFs with smaller JPG sprite videos
- add pause and reverse playback controls to canvas animations
- chain multiple video clips with onEnd callbacks

## When to choose
- you need lightweight, dependency-free silent video playback on canvas
- animated GIFs are too large or low quality for your short clips
- you need programmatic playback control (pause, reverse, loops)

## When to avoid
- you need audio in your video playback
- you need long videos - sprite image size limits frame count
- you can use modern HTML5 video with autoplay support

## Facets
- artifact type: library
- maturity: maintenance
- function: video-processing, animation, ui-components
- domain: web-development, frontend, media
- platform: browser
- tags: canvas, video-playback, sprite-images, gif-alternative, no-audio, dependency-free, javascript
