The Basics
How do I add a video to my blog or web page?
You'll need to edit the HTML of your blog entry or page—this should be relatively straightforward. In Blogger, for example, just click the "Edit HTML" tab.
Next, go to the video that you want, and look for the 'Embed' box in the "About This Video" section. Copying the HTML code that's there into your website will create an embedded player; the video will play within your site when the user clicks on the 'Play' button.
You can resize the player by editing the object width="425" and height="350" fields at both the beginning and end of the embedded player code. Make sure that the sizes you choose have the same ratio as the default numbers, so that the video doesn't get stretched—just multiply the width by 0.8235 to get the height.
