I was given a large number of PowerPoints slides that are in a 3:4 ratio. I need to convert them to 16:9. so they can be embedded in a video.
Is there a way to place them on a black 16:9 background without distoring the original slide. The slides have already been batched to the correct size to fill the background by height.. now I need to automate placing them on or replacing the placing the background.
Any suggestions??

Thanks
