I need to email a fragment of a video that I extracted with DVDShrink from a movie. What's the best format for emailing that fragment? How can convert it to that format with Nero 7, if possible?

Dell XPS 400: Pentium D, Dual Core Technology

DVDShrink 3.2

just a little more info on which email program you use will help on which AVI format will send via email.

For starters

If your using GMail

How do I send a movie file "clip" via Picasa?To send a movie file via Picasa you will need to use your default email client or Gmail. Follow these steps before sending a movie file via your e-mail client:

1. Open Picasa.
2. Click "Tools".
3. Click "Options."
4. Click the "E-Mail" tab.
5. Set the "When sending movies:" option to "Full Movie."
6. Click "OK."

Please note that even small movie files tend to be very large in file size and both the Picasa Mail and Gmail services limit each message to a maximum of 10 MB. Also, it may take a very long time to send the email. We would recommend against sending movie files to people using dial up Internet connections because it may take hours for them to download the file

Browse for the video files you want to use and highlight them before you click the Open button.

Why not use a file sharing service. There are some free ones, try Zshare. As for the format I would recommend an ISO file.
