Video Files

I have a question regarding inserting/playing videos onto my Prezi.

When I save a video onto my computer at home, then insert it onto my presentation, will the video still be able to play when I present it on the computer at school? Taking into account the fact that the video isnot saved as a file onto the computer at school.

So I am wondering whether or not the video will only play in the Prezi when I present it at home, rather than when I also play it on the school's computer.

I don't want to show my Prezi at school, only to find out that the video won't play and I'll have to copy & paste a link instead.

I hope I worded my question good enough!

Thank you,
