Make sure to choose one of the video formats that is supported by d!nk and PowerPoint: .asf, .avi, .mp4, .mpg, .mpeg, .swf, .wmv and .3gp.
Handy to know: Since .mov files (Quicktime videos from Apple) are not compatible with Microsoft PowerPoint, you can still upload your video by converting the .mov file into an .mp4 by using a conversion tool like Handbrake.
When creating the .dink file, the plugin will convert the video files to the compatible tablets format.
It could be that you need to download the latest version of QuickTime-player, to be able to insert your video in PowerPoint. You will then receive this pop-up:
Not supported video functions by d!nk are: 'Automatically - Play full screen' and 'Hide when not playing'.
