Sony Vegas CBR and VBR

I posted earlier about something that has helped me a ton and thought I'd share one more nugget (it's worth I'll leave to the community to decide).

Oftentimes VBR is the preferred method when rendering as it provides for a smaller file size and in theory should provide for a clean distribution of high bitrate and lower bitrate frames. However, there are times when certain video (for whatever reason) does not respond well to VBR. Example, when I render footage for one game in VBR I get some drastic bit rate bouncing that results in significant loss of quality from frame to frame.

So, the workaround I use for that specific game is to use CBR which keeps the quality consistent at the expense of a larger file size (a sacrifice I will make as quality reigns supreme). If you see loss of quality using either VBR or CBR you might consider checking the "two-pass" option in rendering. I'm no editing guru but essentially two pass is like grilling a steak well. It may take a little longer but there is zero chance you catch salmonela or undercooked food disease or something like that...

Hope this is helpful.
