Andy Plesser posted this follow up interview with Kevin Towes from Adobe who goes into more detail about H.264 and the difference between high quality and high definition video. Towes describes container formats like .flv, .rm and .wmv as "end of the line" formats because that's all you can use them for since they are encoded to their proprietary formats. H.264 is more of a universal format that can delivered in both Quicktime and Flash formats which offers a greater ROI on your transcoding.How do you deliver a HD experience through broadband? 1080p demands 15 Mbps and the web can't sustain that level of streaming. Towes says that we need to develop a "Web HD Concept" that can emulate a HD viewing experience but not deliver a true HD signal. You could have widescreen video, a certain frame size with a variable bit rate to achieve high quality with H.264.
The fact is that H.264 video looks great, it's scalable, standards based and can easily be delivered in a variety of formats. It's been several years in the making to reach its current state of adoption and could be widespread throughout the online video ecosystem by the end of the year. From digital device, to digital television and Blu-Ray disc you'll start seeing it more and more.
Kevin Towes' interview continues as he describes that file size is based on frame size, frame rate and but rate and how it can be estimated.
