The quick answer? MP4. But, wait. There's more...
In this video, I talk about the importance of optimizing your screencasts and videos for the web. This is especially important if you're self-hosting your videos either on your own server or on a service like Amazon's Web Services.
Non-optimized video can cause loss of viewers, and even loss of sales if you're using video for marketing purposes. If, because of un-optimized formats and settings, your video ends up stopping / starting, and otherwise stuttering in those annoying ways they occasionally do, then you can bet your viewer will just click-off and go somewhere else.
I mean, think about it: wouldn't you?
"Why not just use YouTube?"
Well, in fact, services like YouTube, Viddler, Vimeo, and so on, do in fact do a good job at transcoding your video in such a way that they're optimized for web delivery. But, there are some very good reasons for self-hosting. Not the least of which is accommodating custom actions (as I'll demonstrate in the video above). Also, security for some videos that you don't want to make public is another reason you might want to self-host your video.
The good news is that optimizing video and screencasts for the web isn't tough. There's even free software I'll show you that will help you make video for the web sufficiently optimized. Check out the video above.
