Putting video clips on my blog was a bit harder than I expected. I first tried converting the .MOV files the camera writes into .avi files using ffmegX and posting them using <embed> tag code. The files showed up great on my Mac but not at all on a Windows computer.
Flash format files, .flv, are the easiest cross-platform way to post video clips. Flash does require that the site supply a Flash player. There are many Flash players available. I tried OS FLV and it worked nicely.
