I heard animated gifs can be even larger than movies because each new gif frame loads an entirely new image whereas video codecs will only change pixels in a frame that are different from the previous frame’s pixels. It’s probably more complicated than that but some gifs can reduced to a 48:1 ratio …

Is there any file format to replace animated gifs?
