There is also Shutter Encoder at www.shutterencoder.com which isn't as popular as handbrake, but it's highly praise. Remember, mp4 is an older less complex format that works well across any machine, even older ones. Therefore, the file is usually a lot bigger.

Btw, always play around with the setting to get the perfect file size to quality ratio that you need. Every program is different.
