I was referring to the flash player in general and wasn't suggesting the flash container itself requires significantly more resources on the client side. (Also, flash is a container format; 264 is a compression format, so not completely sure what your question is.) Even so, when Adobe/Apple rolled out their 'compromise' last year, there was the usual hang-wringing about battery life browser performance; although to my mind it's not clear how a custom rolled app that plays flash video from a specific site (eg. Hulu) would *necessarily* realise significant performance gains. (At just 5MB the whole binary itself weighs in on the low side of a typical app, and not likely the app porter is going to improve its performance.) But then I haven't built an app such as that, myself yet. stay tuned, forest mars -- mnn.org http://mnn.org
Re: [videoblogging] Brief history of video compression
Video compression (especially proprietary) is a bottleneck with online video. Just the opposite ... video compression is a boon to online video. If there were no video compression there would not be any online video. Very very true. Improved video compression has helped spread web vide the last 10 years. My more specific point is simple this: video codecs have gotten better...but the fight between the proprietary standards is hampering online video from further spreading. The idea of people editing video like they edit a text document is still a long ways away. Why? Because every platform uses different standards. Its difficult for a PC and mac to trade video files without a lot of conversion nonsense. Flash is pretty universal for playback but useless for editing. Open Source community cant really build good video editors without stealing compression technology. I cant play Flash videos on my iPhone bcause Apple doesnt want to pay Adobe for the rights for the codec playback. These are problems.

While there has been much rampant speculation, and Apple has said/implied different things at different times, I'm inclined to believe them when they indicate the client-side cpu requirements, which is one of the things that makes flash so appealing, were a decisive factor. Not that it can be reduced to a single deal-breaker and not that Apple doesn't have plenty of other examples of taking their toys and going home when they can't get what they want (ZFS comes to mind.) cheers, forest mars -- mnn: you're what's on! http://mnn.org [Non-text portions of this message have been removed]

Re: [videoblogging] Brief history of video compression
This article is awesome to me. Back in the early 90s, I was helping my dad's publishing shop produce multimedia CD-ROMs. Breaking the 320x240 vidoe size barrier was a dream for me, until one day I realized that pixel-doubling in Macromedia Director didn't make the video look too bad, and it was immersive to boot! To help Jay explain the bottleneck, if we look at production in the lens of video media literacy, the digital divide would look like this: [image: 4244864841_363a04f890_o_d.jpg] I've used this chart in my classes... it's from Knowledge of Digital Video Manipulation Techniques and its Effect on the Preceived Credibility of Television News by Arie Stavchansky (2006).

[videoblogging] Brief history of video compression
Nothing groundbreaking here if you're familiar with video compression, but cool to see it all in one place. http://arstechnica.com/gadgets/guides/2009/12/from-cinepak-to-h265-a-survey-of-video-compression.ars For people still new to what video compression is, it's a cool article.
