Hi Darcy and welcome to Heroes,

If you are unable to import or convert a video, please close PowerPoint and install the following codec packs: 

K-Lite Codec Pack Full (accept all default installation options):

Media Player Codec Pack (deselect toolbar options during installation):

Then, restart your machine.  If you still have the issues, then it's likely that the video was converted using a proprietary codec that Articulate cannot use.  Thus, you may need to reconvert the video using a different program (like Articulate Video Encoder).
