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.
How do you convert PowerPoint presentation to WebM?
You may be dazzled by a huge range of PowerPoint-to-WebM choices. To make it simple, here we are to introduce two most frequently used methods of converting PowerPoint to WebM video.
Method 1 Using third-party PowerPoint to video conversion software
PowerPoint to Video Pro is a standalone software program that enables you to capture all the sounds and frames from your PowerPoint presentation and save to any video format like AVI, WMV, MPEG, flv, MP4, WebM, VOB, 3GP, 3G2, MOV or DV.
To save PPT to WebM video with the magic software, perform these 5 steps:
Step 1 Launch the software to add PowerPoint files
Once the Best PowerPoint to Video is installed on your computer, run it and click Add to import a PowerPoint file for conversion.
Step 2 Specify a directory for the output WebM video
By default, the output style is set to WebM at the first use of the software. Set an output folder for the video file to be generated.
Step 3 Make advanced settings in the Profile interface
Click the Settings button next to the Profile field to enter the Profile field. Make advanced settings for audio and video parameters there. Then click OK to save the current settings.
Step 4 Customize for the output video
Click Customize to make custom settings for the output WebM file. Set any tab of Timing, Music, Audio, Slide and Conversion as necessary.
Step 5 Start converting PowerPoint to WebM video
Click the Start button to start converting the presentation to WebM video. Leave the final task to PowerPoint to Video Converter Pro and get yourself a cup of coffee.

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).
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.
