The EDIUS 5 Video Editing Software from Grass Valley is an NLE editing software suite designed for broadcast professionals. It will allow you to convert different HD and SD resolutions, aspect ratios and frame rates in realtime.
An array of filters, keyers and transitions lets you refine and enhance video projects without the need for rendering. The software directly supports OHCI FireWire, as well as Grass Valley's range of realtime editing hardware cards such as the ACEDVio, and HDSTORM for accelerated realtime editing and analog connectivity.
