Just create a quicktime object in your html mate, and then configure the source parameter to match the filename of your video.
Something like this:
Code:
<OBJECT CLASSID="clsid:02BF25D5-8C17-4B23-BC80-D3488ABDDC6B" WIDTH="480"HEIGHT="272" CODEBASE="http://www.apple.com/qtactivex/qtplugin.cab">
<PARAM name="SRC" VALUE="videos/MyVideo.MP4">
<PARAM name="AUTOPLAY" VALUE="true">
<PARAM name="CONTROLLER" VALUE="true">
<EMBED SRC="videos/MyVideo.MP4" WIDTH="480" HEIGHT="272" AUTOPLAY="true" CONTROLLER="true" PLUGINSPAGE="http://www.apple.com/quicktime/download/"></EMBED>
</OBJECT>
You'll need to provide information on how to download quicktime etc if the visitor doesn't have it, but this is the quickest way of providing Mp4 vids via html.
Flash video is much nicer (most people have the Flash player and its a highly compressed format), but that will obviously involve some recoding on your part.
