Method 2 Convert PowerPoint to YouTube video online
In previous post, we have introduced Online-Convert.com, which offers the service to convert PowerPoint to video. Here is another site with the similar function. Authorstream.com is a platform for sharing PowerPoint presentations online. After you have uploaded your presentation to Authorstream website, the presentation will be converted into a MPEG4 video (*.mp4). An email notification will be sent to you as soon as your PowerPoint video is ready for downloading from the Web. Then you can upload converted PowerPoint to YouTube.
However, this conversion process may take some time, and there is limitation on the file quantity and size for free users. As method 1, the output video could only show the plain content without effects.
Method 3 Use PowerPoint to YouTube converter
To sum up, if your PowerPoint slides only contain text and image, it is enough to convert PowerPoint to YouTube free with Windows Movie Maker or a web-based service. If your PowerPoint file is rich with animations, transitions, inserted files and video clips, a professional PowerPoint to YouTube Converter is better.
