Yep, Flash is good, or rather .flv. Flash enables internet users on different operating systems can view your videos through their web browser, via the widely available Adobe Flash Player and web browser plugin. So you can transfer your videos from your camcorder to computer, to save time you can use video converter to convert it to .flv.
Then you can make a .swf file, which is a flash video player to control the playback of the .flv files. Then you can embed the .swf file to your site. However if you don't know all these stuff, you can use this flash video player maker, which I think is an easy solution to convert videos to flash and add them to web pages.
