U Tube.. uploading PowerPoint/Word/ Publisher - how do i do it?

Ive tried to upload a power point to U Tube but it says wrong format.. how can i change this to the correct format or how do i upload it as it is?

thanks

On Utube you can only upload video files. To show the information from PowerPoint Word and Publisher, create a video. Use Windows Movie Maker to do this, create a video by just adding photos. To take photos of your Word, PowerPoint files, screen shot them using the print screen button. Paste the screenshot into Paint, save it as a Jpeg and import it into Windows Movie Maker, you can create a new image for every slide in the PowerPoint. When finished save your Windows Movie maker project to a video suitablte for playing on your computer then upload it to Utube
