Apple Store App Preview Video Resolution

Question

I am trying to make a video for App Preview in Apple App Store. I created video using QuickTime Player, making a screencast of simulator. After doing this i imported this video to iMovie and performed some changes. I now want to export this video for App Store, but iMovie doesn't offer the resolution of 640x1136 for shared video as a file.

I exported in highest resolution and imported in QuickTime Player again. QuickTime Player has option to export video for iPhone 5, iPAd 2 etc. So i tried that, but the resolution stays the same only file format has changed.

How can i create 640x1136 resolution video that is created in iMovie or are there some alternatives?

SOLUTION:

Thanks, i ended with camtasia. I exported HD imovie video file to camtasia and cropped the video to desired resolution. Export worked!

Answer 1

If your original video is the wrong dimensions for the app store - here is a trick using just iMovie and Quicktime to get the right dimensions.

1. Use QuickTime to record a short clip from the size of the device you need
2. Use iMovie and insert that clip into a new "App Preview" project
3. Add your actual video after the short clip

Now, any clips that you export will be in the right dimensions.

If you need to hide your short clip, you can shorten it to 0.1 seconds. Put a title over it and delete the text. Now your video starts with 0.1 seconds of a black screen.

NOTE: @Spoek's comment below is worth noting - adding an image of the right dimensions works too and creates a freeze frame. @SpaceMonkeys comment below as well - you can delete the image after adding it.
