The only video embedding option is Youtube. But the video is shown on the menti presentation with a gray border (design issue) as well as with "other recommended videos" after the video clip has ended (unprofessional and unnecessary content).

Furthermore, sometimes space can start/pause the video other times not, but instead one or two clicks with the mouse are needed (messy UX design and unprofessional to have to show a cursor).

Having video slides with Youtube embedding "cleaned up" to a more professional look with easier control would be much appreciated.
