How to Convert PowerPoint to WebM video format?

What is WebM?
WebM is the new generation multimedia container format sponsored by Google to provide a royalty-free, high-quality open video compression format for use with HTML5 video. A WebM file consists of VP8 video and Vorbis audio streams, in a container based on a profile of Matroska. The purpose of the container is to hold the video and audio streams so they can be synched for playback. The container is comparable to a QuickTime or MPEG4 file.

Method 2 Creating WebM video from PowerPoint with Screen Recorder
A screen recorder like SnagIt can also record your presentation playing on a PC screen. It grabs your slideshow at about 10 frames per second when no video clip is embedded in the PowerPoint presentation. But if a full motion video is there, you have to take a more powerful capture app like Camtasia ($299 per copy).

Disadvantages:
1. Screen recorders require a frequent reopening of a PowerPoint presentation as they are deficient to process a pile of slides at once.

2. Adding music or narration for the output WebM slideshow is not allowed in a screen recorder as in PowerPoint to WebM Converter.

3. The lack of stability in screen recording may also cause a loss of animations, transitions or sound tracks in the output.

By comparison, it’s obvious that PowerPoint to Video Converter is superior – quick and capable of cloning every shine effect from the source PowerPoint presentation to the targeted WebM video.
