- It is possible to convert a video into a pure CSS animation, where each pixel of the video is represented by an animated CSS element.
- This technique involves downscaling the video, extracting the pixel data, and generating a massive CSS animation with keyframes for each pixel.
- The process can be optimized by skipping keyframes where the pixel color hasn't changed, but this introduces some visual artifacts.
- An alternative approach uses CSS box-shadows to represent the video pixels, which is simpler and more performant, especially on Chrome browsers.
- Browser support and performance varies greatly, with Safari handling much larger CSS animations than Chrome before crashing.
- The final CSS-based video animation can be further converted into an animated GIF using a library like GIF.js.
- The motivation behind this project seems to be more about the technical challenge and novelty rather than practical application.
- The author emphasizes the importance of style over substance, suggesting this approach could be used for startup landing pages to send a message, even if it crashes most browsers.
- The author hints at the possibility of creating a new file format called ".vibcss" to standardize this CSS-based video approach.
- Overall, the document showcases an innovative, if impractical, technique to push the boundaries of what is possible with CSS animations.
