Tip: make your MP4 web exports stream

Users who export in web-sized MP4 h.264/AAC, primarily from Sony Vegas, create MP4 files that are not streamable via Flash (Flash has had MP4 decoding support for over a year now, but it requires the format to be tweaked, to be “streaming”). Vegas has no such option in their two h.264 encoders it carries. This means that if your MP4 is not streamable, it will have to completely download to the user’s browser cache before it can start playing back. And that can take a long time, aggravating your viewers…

A user over at HV20.com found a freeware utility that will allow users to load their stock MP4 files in it, and make them streamable in an instant. You just chuck your mp4 files in there, and off you go. You can then use them in conjunction to a Flash player application that supports h.264, to stream and playback on your web site (in case you don’t want to use Vimeo/YouTube for some reason).
