The short story:
- Set the Screencast folder location
- Setup a RealTimeSync to a 'Screencast backup' folder
- Run the RealTimeSync on startup
- When you want the source video file, navigate into the backup folder, find the Screencast you want and look for a package.zip. Inside here is the webm file you can copy out and play with VLC or some other player.
You could also use a video converter to convert the webm file to an mp4 or some other format that you could embed into PowerPoint etc.
Muxing webm and ogg (update):
You can use Hybrid to do this... just use passthrough for video, custom for audio, select the ogg, and ensure output container is mkv or webm. Screenshots below:
