Hello
While there are certainly other ways of exporting a movie directly from a powerpoint project, here is a simple workaround that I have found effective.
Clients often bring me all types of media presentations that they wish to incorporate into standard-def projects for DVD output. Now that there are so many proprietary slideshow apps (including and besides powerpoint) it gets to be a time consuming hassle.
To save time, I use a laptop to play the presentation, using the dual monitor function to allow for video output from the laptop which I feed to the capture card; creating a new video file. Most laptops only provide S-Video output of video signals, so an adapter may be needed if you do not have a multibridge.
Of course, I would not recommend this practice for programs you intend to broadcast, but I have found that it is a great workaround to avoid frustration when working with new media in SD projects, such as DVD’s for corporate use….
I hope this helps
