One thing I was curious about is how the PNG would compare after running it through an optimizer since that would be a more fair comparison since the H.264 encoding does optimize. Even so, I bet the H.264 would fare well. I did an experiment with using single-frame H.264 instead of images on a site: I think it’s a viable technique but didn’t have time to flesh it out in full. If you have some kind of asset pipeline for a site it’s not really more work to encode and the HTML is now a video tag with no player controls so isn’t a ton of work client side either. Would love to explore that more at some point.
