will cs3 work with the canon h.264 stuff? afaik, it won't smart render avchd, i think that you need cs4 for that.
nero is basically a bunch of programs that are all put together under one roof, so you can do all kinds of stuff with it... the editing software is very rudimentary, it has a horrible interface, as compared to cs3.
but the nero encoding software is xlnt, i'd rate it better than cs4, which uses the mainconcept h.264 encoder... although the latter is very good in its own right... it's the kind of a situation where you could throw some more bitrate at the mainconcept encoder, and you'd have a hard time telling the results from the nero encoder.
it would be interesting to see if nero can smart render this 5d footage, it's a lot less complex than avchd, canon jacked the bitrate way up to increase the picture quality.
if you are editing on a pc, be aware of the quicktime gamma problem: http://www.dvinfo.net …icktime-h264-problem.html
