GIF-style video

Animated GIFs can be 5-20x larger than the equivalent MP4 video. However, MP4 videos can be configured to look and feel like GIFs by including the autoplay loop muted playsinline attributes on the <video> tag. In addition, to prevent layout shifts, make sure to set the width and height attributes. For instructions on converting GIFs to MP4, see Create MPEG Videos.
