I think this is a front-and-center topic for Freeway users, not necessarily off-topic for the main list. That said, here’s the difference between these formats:
QuickTime is a container format, and can contain any number of different media types. It provides common controller commands and mediates between the browser and the medium through a plug-in. The most common content format found within a QuickTime wrapper these days is MPEG4, which is simply an ISO-standardized flavor of the original QuickTime media format. HTML5 video is based on MPEG4, which is to say QuickTime. All modern browsers (except for FireFox, for reasons of patent-mongering, rather than any technical reason) can play QuickTime MP4 content directly – without any plug-in – in an HTML5 page within a video tag.
Now if you were to ask any random number of people whether they had QuickTime installed on their computer, very few would probably raise their hands. Ask the same group how many had iTunes installed (or better, just ask if they own an Apple iPod) and quite a lot more would raise them. That latter group would probably have to be told numerous times that this meant they had QuickTime installed before the truth would sink in. iPod and iTunes are the camel under the tent flap for QuickTime, and at this point, with something north of 90% of the technological world owning an iPod, QuickTime has never seen such universal installation rates. (Not that long ago, the same could be said about Flash, but owing to the immense popularity of those same iPods and iPhones and iPads, in pure numbers of Internet-capable devices – not just computers any more – that percentage is steadily dropping.)
In comparison, FLV is a media format, and it does not have its own container format. There are no browser plug-ins for playing it back. Instead, you have to wrap an FLV inside a SWF player to create the container. This reliance on SWF – requiring in turn the Flash plug-in – means that along with Flash, the FLV video format is going to become ghettoized as more and more “post-PC” devices are made and sold. (The dirty little secret here – FLV is, for all intents and purposes, MPEG4 video.)
So to sum up, QuickTime is the more universal choice, more people can play it back than you (or they) would expect, and using QuickTime makes it a simpler step forward to make HTML5 pages. Using Flash and FLV restricts the number of people who can view your work, and is backward-thinking rather than forward-thinking.

Could someone help me with the difference between a Flash file and a Quicktime file of the same video for embedding into a Freeway page? Which one plays better? (I originally posted this in the Freeway Talk by mistake)
