I have edited HD 1080p footage from my Nex5 camera and want to render it via a vegas pre-set to play from USB on my Bravia TV - the USB video player supports
AVC/AVCHD/DivX/MPEG4
What export setting would give me the best quality?
Assuming you are in the US, Sony AVC Type, AVCHD 1920x1080-60i template would be my assumption, but I do not have that TV. Make sure you have a fast USB device so that it keeps up with the bitrate.
NEX 5 is great, very good stills and video quality, superbly built, tiny form - the only caveat is the poor user interface...
lots of functions are hard to change without navigating endless menus...
