I need to record me using an iPad while I am drawing on it (with Penultimate). I usually use ScreenFlow to record onscreen actions on my desktop Mac, so I need a way to display iPad on my Mac. Is there a way to do screen sharing? Or, I suppose I could do a screen capture right from my iPad. Any suggestions? Thanks,

UPDATE: One solution for 10.7.3 and iPad 3 is Reflection + ScreenFlow, no cords:

Tricky one, but you can rig up a solution - I'm not sure about the final quality though.

First, you need to allow your iPad to use AirPlay Mirroring with your iMac as the target device.

To do this, you need to use a program like AirServer ($15 for a single user license) or Reflector ($15 again, but has a trial at least) or AirMac (Free, but not as fully featured) or AirPlayer (Similarly beta). Mountain Lion will have this feature built in, potentially.

When this installed, check you can get it to work - so ensure the iPad and iMac are on the same wireless network, and turn on Airplay Mirroring, pointing it at the correct host:

enter image description here

You should get a window displaying the contents on your Mac. Note, than even if you are using the top of the line iMac, the resolution of the iPad will still be too large to view without scaling, so expect some downscaling, either by the airplay protocol or the receiving app anyway, simply to ensure it fits on your screen. Given a choice, a neat halving to get the original 1024x768 resolution should suffice. The method of doing this will be different depending on which app you end up using.

Once you have a window running with out iPad screen in it, you can capture it with Quicktime. I note that you already use ScreenFlow (which I missed at first), so you can do this your own way, but for everyone else you can do it with build in tools like Quicktime. I am going to assume you are on Lion. Open up Quicktime Player, and go File > New Screen Recording Hit the big red recording button, and you get the message Click to record the full screen. Drag to record part of the screen Drag a neat square over your Airplay receiving window, adjusting as required to get a neat fit, then hit the record button in the middle, and do your stuff.

CAVEAT: Lots of things can affect quality using this method. Your wireless network may be slow, resulting in dropped frames or lag when recording. Your computer may be slow, or busy, resulting in dropped frames etc etc etc. Quicktime (if you use it) is already by definition recording a compressed video, not raw, and it's using an image source on your screen that is already displaying a video that has been compressed down from Retina resolution to something saner for desktop use. This method works, but the resulting video quality can vary wildly depending on your setup. You can mitigate to an extent with thoughtful configuration of your network and so on, or by using more expensive screen capture solutions that record raw etc, that but is up to you to decide how much quality you need. As it stands, the test video I put up was more than sufficient to be perfectly pleasant on YouTube.

Now, time to own up, I cannot get it to work with the free versions on offer, but I have in the past, so I'm throwing the solution up anyway, in case it's just me being stupid.

I have used the trial version (limited to 10 minutes) of Reflector though, and created the following video as an example, proving it can be done, but you may need to cough up for paid software to do so:

thanks, lets see what I could do with Air(s)... Can you do it with a VGA2USB adapter? –  janeh May 3 '12 at 15:15
    
Nice solution @stuffe. janeh, yes a VGA > USB converter should work. See my amended answer. –  jaberg May 3 '12 at 15:27
    
    
I amended my answer also, I got it working and have posted a video on YouTube. –  stuffe May 3 '12 at 15:33
    
^ do you have a link to the video? :p –  janeh May 3 '12 at 15:56

On an iPad 2 or iPad (3rd Generation) almost every video signal can be mirrored out via the dock port and an appropriate cable/adaptor — VGA, or HDMI. That video signal can be input into a capture device, be that a computer or a dedicated device.

I've linked to the Apple versions of the video out adaptors, but there are also third-party versions available, often at a lower cost.

Apple sells a composite video out cable that fits into the iPad dock but, unfortunately, video mirroring doesn't support composite output. If you want to use a composite capture device for the Mac, for example, the Elgato Video Capture , you'll need to use the Digital Video (HDMI) adaptor and an external device to convert that signal to composite video. You can also do the same from a VGA output using a different converter. Again, these products are linked for reference only, I'm not endorsing hardware or source.

If you can live with lower resolution, Steven Sande outlined a budget solution for getting analog video into a Mac in TUAW's iPad 2 video mirroring to Mac, the cheap and dirty way

Personally I would use a hardware solution or the AirServer workflow and avoid the security and functionality risks inherent to a jailbreak, but that's a personal preference. If you do decide to go the jailbreak route, be certain to educate yourself as to the risks as well as the benefits and make your choice accordingly.

If you've jailbroken your iPad (which you'll be able to do within a few weeks), there is Display Recorder ($1.99).

Another way to do it, is explained in this MacMost podcast. But it involves a huge setup (including a HDMI cable and extra software on your Mac), so I would wait for the jailbreak :)

I haven't jailbroken it, I won't be trying it just yet - I am not a hardware person, and I'm afraid to completely mess it up! –  janeh May 3 '12 at 15:16
