Is there a way I can capture my iPhone screen as a video?

Short of using a video camera, no.

Many youtube videos for demonstrating iPhone applications are made with a screen grabber application (such as iShowU, ScreenFlow, or Snapz Pro) and the simulator. Be aware that the speed of response in the simulator can be dramatically different than a device - so it's possible to get effects (and miss) with the simulator you'll never see on a device. In particular, default animations can flash by in the simulator, where they just look quick on a device.

using ScreenCaptureView class we can capture the iphone screen as video.The source code is available here.The recorded video is saved in a NSUrl,outputURL.Use that NSUrl in a method like below to play the recorded video,

    -(void)playvideo
{

  MPMoviePlayerController *player = [[MPMoviePlayerController alloc] initWithContentURL:outputURL ];
       [player.view setFrame:CGRectMake(0,0,320,480)];

[player setMovieControlMode:MPMovieControlModeHidden];   

[player setScalingMode:MPMovieScalingModeAspectFit];

 [player setBackgroundColor:[UIColor blackColor]];

 [player setFullscreen:YES animated:YES];

[player play];

[self addSubview:player.view];

}

call this method before releasing NSUrl in completeRecordingSession method ..it will replay what you did in the iphone screen as a video.

www.iphonevideorecorder.com. There's a free trial I think, but after that you'd need to buy it. And you need to jailbreak your iphone.

I've continued to research this item myself, and it does appear to remain beyond us at this point.

I even tried buying a Apple Composite AV Cable, but it doesn't capture screen, just video playing like YouTube, etc.

So I decided to go with the iShowU path and that has worked out well so far.

Thanks Guys!

For a nice looking screencast, have a look at SimFinger. You will still need a screen recoder such as Snapz Pro.

I dont believe this is possible. Your best bet is to get something like iShowU and capture from the simulator.
