Hello. What is the input and output format are you trying to convert ? Prism allows to resize(change the resolution) for the entire video. Please, go to File Settings(button on the main window) -> Video Output Options -> Resize Video Checkbox -> type the output resultion. Also it's possible to constrain aspect ratio of the video. As for the kbps. You can type any kbps value you like in the encoding settings for some formats like MP4 or MPG. Also, if the "default" quality preset is used the kbps value is hardcoded inside the application. It's possible the VideoPad's hardcoded value and Prism's hardcoded value are different. But it's really weird why do you get 480x480 output video. Please, share the encoding settings you try to apply to the input file.
