Movie Maker Does Not Play Or Convert iPhone Mov Files

When you drag or import you video into the program then try to play the video it only converts the audio and the video is not displayed.

You are missing a codec

In my version of Movie maker 2012 (build 6.4.3522.0110) there is no way to enable codecs automatically as there was in a previous versions.

Fix

Download the latest K-lite codec pack (basic will do) : https://www.codecguide.com/download_kl.htm

Your MOV video will import fine now.
