@thecreativeone91 I thought that the HTML5 spec was going to have specific file and codec types specified. Was that dropped?

No. it just provides a way to present the video. It's up to the browser to support the codec. H.264 is the most common, but even then there are differnt types as it's a GOP codec there's I frames and P frames. where I frames are key frames and P frames are rendered by the computer as inbetween frames at the time of playback using a lot more cpu. All I frames take less cpu usage but are much bigger in size.
