You can share your movies with friends and family by emailing them directly from Windows Movie Maker in Windows XP. You can send an email message with a low-resolution or high-resolution version of your movie attached.
In the Movie Tasks pane, under Finish Movie, click Send in e‑mail.
The Save Movie Wizard will open and Movie Maker will automatically create a low-resolution version of your movie that can be attached to an email.
On the Ready to Send By e‑mail page, click Next.
The Save Movie Wizard will create a blank email for you with the movie attached. If you want to preview the movie before you send it, you can double-click the attachment and the movie will open in a new window.
When you're ready, click Send. Recipients of your email message can watch the movie by double-clicking the attachment.
In Movie Maker, click the Tools menu, and then click Options.
In the Options dialog box, click the Advanced tab.
Under e‑mail, click the up arrow to increase the maximum attachment size, and then click OK.
