MediaCalc has just been released on the App Store. I’m using this app for quite a while now and it’s really useful.
The developer’s simple description:
"MediaCalc is a tool to calculate the optimum datarate before encoding a video stream."
You can give it any numbers and MediaCalc will tell you exactly how big a stream will be after encoding. Really useful for shrinking DVDs to a MPEG-4 movie.
Also: MediaCalc is free. Free as in free beer.
Go get it!
