By the way, you can actually achieve better (more efficient) encodes in post than the camera can achieve in real-time. I use proper h.264 encoding (very slow) to achieve the original file quality (24mbps) with bitrates as low as 3mbps!

Oh really!? So use AVC h.264 or AVC will no longer be a necessary codec aspect?

AVC is actually h.264... there's just software out there that does a far better job of encoding it than Vegas does I use StaxRip, which is simple to use, but you must go into the codec options and set it to max. efficiency to get the most out of it. Really stunning results.

Can you explain your work flow with this Mathew. Do you render out a video in your editing software if so what format ? Then do you re-render seperatly with StaxRip to get a smaller file size ?

I'll do a detailed guide on it soon, but basically I render out from Vegas an uncompressed avi file (it's not uncommon for them to be 100GB in 1080p, so make sure you have the space!), then I import that file into staxrip, and set the encoder to "placebo", up the audio bitrate a bit, and set the container to MP4. Takes ages to render, but it's worth it! I'll see if I have the time to do a quick guide and provide some samples to show how good it is.
