With Knovio, take your existing PowerPoint slides and quickly and easily add your own video to synchronize with the slide content. You can then share this new presentation out to your intended audience by email or social media.
You don’t need any special software to use Knovio. From a standard web browser you simply upload your existing PowerPoint files. You will need a webcam and microphone to record your video and audio which is already installed on most laptop computers.
