Common video formats or file extensions supported by PCs, Macs and the Internet include FLV, AVI, MP4, and MOV. All file types are compressed with a certain number of "bytes," or size of your file, depending on your extension. Email attached videos must be heavily compressed, as generic email accounts have a file attachment limit.
Step
Go to nchsoftware.com (see Resources). Scroll down and to the right until you find "Download Prism..." for your Mac or PC. Click the appropriate "Download Prism..." button.
Step
Open the "dmg" file. This will install "Prism" for you. Find and open the "Prism" icon.
Step
Either drag your video into the converter or click on "Add File(s)" in the upper left-hand corner. Find your video file and click "OK" or "Choose." Now your video will be in queue to convert.
Step
Scroll down to "Output Format" in the lower left-hand corner. Click on the pop-up tab to its right and choose your preferred output. Since we are converting for email, click on the ".mp4" extension. This will create a smaller file than the other options.

Attach the video to an email.
