Well I had a hell weekend trying to get Vegas to work but I learned a lot.
One thing is always render in the highest quality codec you can. The sony AVC just sucks.. who cares if it is way faster if its ugly? it was only good for very quick preview quality renders where I just wanted to see the final project.
I recommend to render AT LEAST to the sony MXF 422 or main profile. These are very high quality and most encoders can read them.
I use handbrake which can see about anything.
I honestly just render straight to uncompressed AVI but it takes a lot longer for the destination hard drive to keep up so you will get a faster render with a more compressed codec but I like to switch the project over to 32 bit and render to something that can take advantage of that.. I got a few other codecs that I am going to play with.. anyone ever use cineform? I’ll look into after I figure stuff out.
Just returned my 460 and got a 560 so I am looking to see if that helps any with editing and rendering but I doubt it.
