Feels too long. After about a minute I got the point and skipped to the end. The site seems easy to use, so I don't think you need such detail. If users are having trouble learning how to use the product, consider splitting up the demos into multiple videos so I can watch short segments.

The script felt very wordy. The words and screencast should compliment each other, but they felt very duplicitous here. I'd cut out 30% of the voice over, allowing the video to get the point across. My favorite resource for learning how to be concise is "On Writing Well" by William Zinsser. Check it out.
