I am getting almost the same problem. My video plays fine on the computer, but when I try to view it on my ipad 2, no go. Just a black box.

Admins, please help.

in fact it is here but just the playing bar, it seems to be a sound not a video. It is also very big regarding the rest of the prezi.

try to mouse over it to see it and shift + drag around to select it (in order to delete it).

you may convert it to flv.

@ Aram

please open your own topic because this is not the same problem :)
It is possible that your video's resolution is too high for the iPad to show. Open your prezi on your computer and replace the video with a max 720p version.

please provide the edit URL of your prezi for a prezi team's member to check
