You’ll want to adjust the size so it’s 4:3 with square pixels since a 720×486 image will look stretched on computer screens, but beyond that it’s up to you and dependent on how fast your viewers’ internet connection is.
With H264 nowadays, you can easily get away with 512×384 and it will stream on most decent speed internet connections. You can even get away with 640×480, although that will likely bog down on anything below a cable modem.
We typically stick with 512×384 or 480×360 or 432×324. You also need to consider the web player you’ll be using…meaning Flash, Quicktime etc. If you use Flash, you’ll get better results keeping your sizes as multiples of 16 or at the very least 8.
