Altering "size" of video

I have noticed that the prezi videos are super large, often 1.5 - 4 GB. Is there a means to alter the quality to reduce the size?

Hi @Helen_Alcock-Towse, could you tell me if you are recording videos with the desktop application or on the browser version of Prezi Video?

I would like to know if there is a way to reduce the size as well. I just recording an hour long video and it was 9 GB!!! What the heck. I have the application downloaded on my computer.

Hi @Marsha_McGuire, could you tell me which mode did you choose when you were saving the video after recording? You should have several export options at the end of the video recording with the app.
