Hi Duron,
Thank you for contacting Microsoft Community and we will be glad to assist you with your concern. As per the issue description you're unable to insert video in PowerPoint 2010.
This issue might have occurred because currently the Windows operating system does not have a 64-bit video codec for the three QuickTime media formats.
Refer to the knowledge based article which discusses about the similar issue and check if it helps:
