I’ve been using a free app called Video Monkey for a few years now. Video Monkey is a video encoding application for Mac OSX and it does an excellent job at transcoding media files. I usually use it as my final deliverable render, meaning it does the last encoding pass before I send the video off to a client or post online. It does a nice job of taking a few extra pounds off the data size of the video and keeps the integrity of the image quality fantastic. Oh, and did I mention it’s fast?
