If you have any need for an iOS screen-recording app, and you don’t mind wasting $2, then go download Display Recorder right now. Don’t worry – I’ll wait.
Usually, if you want to record the goings on on your iPhone or iPad’s screen, you need to either mirror it via a cable to a recording device, point a camera at it or jailbreak the thing. Now there is a fourth, and Apple-approved, way. For now, at least.
Display Recorder is an app-store app which does what it says: record the screen. You start the app, press record and go on about your tasks. The app continues in the background, grabbing both video and sound.
It works great (although a bug in the current version means it won’t actually record video unless your region formats are set to US), and you can specify various audio codecs, video quality settings and even choose “direct access” or “screen capture” modes. Direct access tapes the whole thing, whereas screen capture appears to omit various transitions between screens and apps.
The only problem is that it is jerky. The results might be good for showing a friend something cool (via the built-in YouTube uploader) but for screencasts it doesn’t really cut it.
Then again, I’m capturing video from the huge screen on the iPad 3, so it may be better with smaller devices.
Anyhow, as this kind of thing seems counter to Apple’s App Store rules, it might be worth grabbing this quick if you have any need for it. You never know how long these things will last before Apple spoils the party.
