Capture and Record Video from Apple iPad

The new iPad by Apple, a supersized version of the iPod/iPhone, is a tablet computer that features a 9.7″ display with multitouch touch screen technology, running at a resolution of 1024×768.

Recording the entire screen would come in very handy for development, troubleshooting, training videos, demos, podcasts, and even direct broadcasts from the iPad screen.

While a native software solution to iPad screen capture is either weak or nonexistent, there is an ideal and low-cost hardware capture solution that will allow you to capture the entire contents of the screen without slowing down or otherwise altering the functionality of the Apple iPad.

This solution consists of two things: the Apple iPad dock connector to VGA adapter (pictured below), available from the Apple store ($29) and the Epiphan Systems VGA2USB ($299).

The iPad to VGA dock connector currently allows you to add a VGA port to the Apple iPad and mirror the image on the iPad’s screen on the output. In the future, Apple will add support for applications to use this external output.

In order to record video from Apple’s iPad, we must begin by connecting the iPad to VGA adapter to the iPad, and connecting the Epiphan Systems VGA2USB to the VGA side of the adapter. A more detailed diagram is shown below:

The captured video from the iPad can be recorded on the computer using free software provided by Epiphan Systems, or any other video capture software that supports external devices, such as Adobe Premiere or VirtualDub.

Furthermore, the images and video from the iPad can also be broadcast using software such as Windows Media Encoder or QuickTime Broadcaster.

How to Take Screenshots on your iPhone or iPod Touch

As long as you have the 2.0 version of the iPhone firmware or above, the iPhone or iPod Touch does not need any special screen capture software in order to take instant screenshots of your screen. Here is how it works:

1. Hold the Home button down

2. Press the Sleep/Wake button

Your screen should now flash white. This means that the iPhone or iPod Touch has successfully captured your screen and saved it as a photo.

3. Your screenshots can be found by pressing the Photos icon.

On an iPhone, you’d have to then navigate to the Camera Roll folder.  On an iPod Touch, the screen captures are saved in the Saved Photos folder.

Apple iPhone Takes Screenshots Without User Consent

Security experts say they have found a hole in Apple iPhone which automatically takes a screenshot every time that you press the “Home” button, and that the images made can be retreived later. Of course, these screenshots are taken without the user’s consent and knowledge. This “feature” is not to be confused with the iPhone’s actual screenshot feature, which archives an image of the screen to the iPhone’s memory whenever you hold down the power/sleep button and push the Home button.

Apparently, the iPhone takes a screenshot every time you press the Home button in order to create the shirinking effect of the application window that was open when the button was pressed, bringing some insight into the way that the iPhone OS works. The iPhone is supposed to remove the screen capture file after the effect has been created. Nevertheless, the screenshots can be retrieved with special software that can analyze the memory of the iPhone for deleted files.

Jonathan Zdziarski, the security expert that discovered the flaw, said that this hole has been used by forensic experts to “gather evidence against criminals convicted of rape, murder or drug deals.”

While most people have nothing to worry about, this issue raises a privacy concern for those that do things on their iPhone that they wouldn’t want others to discover should the phone end up in the wrong person’s hands.

Screenshots, like the one above, are captured by the iPhone every time that the “Home” button is pressed by the user.
