They say a picture paints a thousand words. Screencasts, which are videos of your computer screen and often used in tutorials, are a useful way to illustrate a point or program. ScreenFlow is a very polished screencasting application, which records just about anything and gives you a huge amount of editing options afterwards.
ScreenFlow will record everything from your iSight camera to microphone audio or speaker audio enabling you to add crystal clear commentaries to your screencasts. ScreenFlow even monitors keystrokes and mouse movements, which is pretty clever. The app also has an excellent zoom function which allows you to add a touch of class and professionalism to your screencasts.
Recording quality is excellent, and thanks to a high frame-rate (which you can set), your videos look as if everything was actually happening on your screen. What's also surprising is that ScreenFlow is very lightweight for what is effectively a video editor, consuming relatively few CPU and RAM resources. Exporting is possible in all major formats and YouTube fans can now share their productions instantly.
The program has one glaring drawback however and that's that you can't add text, subtitles or simple text annotations to your beautifully produced screencasts. It's also a bit on the pricey side but if you're looking to produce professional looking screencasts, it's probably worth it.
ScreenFlow is an excellent screencasting application that just lacks text insertion support to make it a truly excellent application.
