Often, a video will say more and better than text and pictures.  E-Bay allows you to add videos to your listings and store pages.

Remember, that if you add video to your listings, you may limit your audence to broadband users only.  That is still OK because most heavy Internet users are using broadband anyway.

You can capture video footage with a web-cam.  You will likely get much better footage from a DV camcorder.

Edit your video to get it to say just what you want.  You can use Movie Maker on Windows XP or iMovie on the Mac.  I am an advanced video professional, so I use Apple Final-Cut Pro quite often, but still use iMovie for really quick videos.  You may have other software you like.

When you are done, save your video into a file inteneded for use on the Internet.  Don't save in 768x480 full quality mode!  Save in 160x240 or web quality.  You could use MPEG-4 H264 (MP4 files) for the best quality, but just saving to a .mov file would be really better.  Don't assume the viewer will be using Windows!  (Don't use WMV files because they don't work on a Mac.)  (I will use .mov files for this example because they are old enough that every system knows about them.)

eBay does NOT store video on its servers.  You need a server to store your video and make it public for your listings.  You can use a service like YouTube.com to store and share your videos - But, those services often take the viewer away from the listing to view the video on some other page.  This is one of the problems with using a Flash Player to view videos.  Once you have done that, you simply cut and paste some HTML code generated for you into your listings.  Make sure you are in HTML mode in the on-screen text editor.

If you have your own server, save the file like you would any HTML file. 
Then add this text to your listing:

<embed
 style="background-color:black;"
 src="http://yourserver.com/yourvideo.mov"
 type="video/mov"
 width="320"
 height="260"
 pluginspage="http://www.apple.com/itunes/download/"
 autoplay="true"
 loop="false"
 controller="true">
 </embed>



There are other players for video, but this will use Apple Quicktime already installed on most systems.
