iShowU is designed to record screen actions on your computer and it does so with a number of easy-to-set options and a robust back-end that helps you customize resolution, file size and output type. The result is a powerful, effective screen capture tool that's perfect for gaming and tutorial videos, alike.
When you first open iShowU, you'll be prompted to give control of your computer to the software. It's unnerving at first, but it only needs to access things like mouse animations to show them onscreen during video recording. By having access to mouse data, it can make files smaller. The interface of the app is a bit jumbled, but everything you need is on one screen. You can choose the video type, size, encoding, and other factors like frame rate, audio levels, input devices, etc. It's a fantastically diverse set of options that allows you to create some solid files, with presets for things like Blip.TV, Vimeo, YouTube, and even World of Warcraft. The entire process takes only a couple of seconds to set up, and it is very "share" friendly, recording in smaller file sizes.
If you need a basic video creator for screen capture on your Mac, consider iShowU. The app is free to try and costs $20 to upgrade if you continue to use it after the trial expires, and while not the most attractive or even the most powerful screen capture tool for Mac, it does offer one of the biggest bangs for its buck out there. It's a solid, well-made tool and one that you'll enjoy using quite a bit.
Editors' note: This is a review of the trial version of iShowU for Mac 1.92.7.
iShowU has specified capture size - the user can easily specify the size of the video to be captured, using an intuitive 'see through' video preview. Just drag the corners around to specify the size, and hit enter. Fixed or follow mouse modes - Sometimes you'll want the capture rectangle (think of it as a movie camera that tracks your mouse) to follow the mouse, and other times, you'll want to capture just one area of the screen. iShowU can do both. User defined audio/video quality - While internet connections are getting faster, it's still going to take a while to transfer a 5GB movie to your Mum. iShowU compresses audio using AAC, and video using whatever method you think it appropriate (it defaults to H264). In addition, you can specify the quality of the video to your liking. Custom frame rates - When there's not much going on (i.e: you're not moving the mouse, just speaking) iShowU will capture at a lesser frame rate. When you start moving the mouse around (and the capture rectangle follow it) then it'll use a faster frame rate so that the motion looks smooth. Saves on bandwidth too. Simple - iShowU is designed specifically to be easy to use. If you don't want to customize anything, it'll work straight out of the tin. All you have to do is hit 'Record' and you'll have a nice little video on your desktop in no time.
