Video NonLinear Editing (NLE)
In the land of NLE, just as Canopus Edius Broadcast NLE supports many inputs. DVCPRO® 50 / DVCPRO HD support DVCPRO P2 support VariCam® support XDCAM™ support http://www.canopus.com/products/nlesoftware.php
Will Vista Movie Maker (VMM) ever provide the same support, for free, for us poor people, who can't afford Professional NLE's, ideally without converting / transcoding just to get the video into movie maker?
Often many non profit community groups and community tv stations may be using secondhand professional video cameras with these formats, so there is a need for a freebie professional NLE.
Also MS can we have WideScreen 3:1 support in VMM for letterbox export into HD-DVD frame (1920x1080).
