Okay, so we can now submit video previews of our apps on the App Store. According to Apple we should do so with an iOS8 device and OSX 10.10. The problem is you have to have all the different devices (4", 4.7", 5.5" and iPad).

Is there an alternative to this?

I am thinking of capturing a video of the simulator. The problem is the device screen is bigger than my FullHD monitor when shown in 100% resolution. Any solution that can capture a video right from the simulator in full resolution?

Edit: Since a lot of people are answering questions I'm not asking let me say: - Recording one device size and scaling it is not what I'm asking; - How to record any app preview is not what I'm asking; - How you do your previews is not what I'm asking;

What I am asking is can you record a video from the simulator in 100% resolution if it doesn't fit on the screen?

For Xcode 8.2 or later

You can take videos and screenshots of Simulator using the xcrun Xcode command-line utility.

Run your app on the simulator.

Open Terminal.app

Run the command

To take a screenshot, xcrun simctl io booted screenshot

To take a video, xcrun simctl io booted recordVideo <filename>.<file extension> .

For example: xcrun simctl io booted recordVideo appvideo.mov

Press cntrl + c to stop recording the video.

The default location for the created file is the current directory.

You can use QuickTime Player to record the screen.

Open QuickTime Player

Select File from the menu

Select New Screen recording

Now from the Screen Recording window, click on record button.

It will provide you with an option to record the entire screen or a selective portion of your screen.

You will have to make a selection of your simulator so that only the simulator portion will be recorded.

Apple recommends doing so on an actual device and has a guide on how to do this using QuickTime and iMovie on iOS and OS X: https://developer.apple.com/app-store/app-previews/imovie/Creating-App-Previews-with-iMovie.pdf

Summary:

Capture Screen Recordings with QuickTime Player

Connect your iOS device to your Mac using a Lightning cable.

Open QuickTime Player.

Choose File > New Movie Recording.

In the window that appears, select your iOS device as the Camera and Microphone input source.

Create an App Preview with iMovie

Import Screen Recordings

Next you import the screen recording files that you captured with QuickTime Player into iMovie. In iMovie:

Choose File > Import Media.

In the window that appears, select the screen recording files.

Create an App Preview Project

To start a new app preview project, choose File > New App Preview. A timeline appears where you can add and arrange clips to create your preview.
