IPhone slow motion video

I would like to import slow motion video files made with my IPhone SE. They come with an AAE file but the information does not seem to come through.

Please understand that FotoMagico is not a video editing software and has only limited capabilities for manipulating video. If you need to change the playback speed of your video please use a 3rd party video editing software (e.g. iMovie by Apple) to slow it down and then export a new video file that contains this slow motion effect. Use this new video in FotoMagico then.
