Re: benefits of constant bit rate versus variable?

You could say that a VBR encode with an average bitrate of 4Mbps and a peak of 8mbps will be equal in quality to a CBR encode of 8mbps. However the VBR file will be more efficient.
You could also say that if you did a VBR encode with an average bitrate of 2mbps and a peak of 4mbps that it will be of higher quality than a CBR encode at 3.9mbps.

Both VBR encodes will usually result in smaller file size.

CBR has the potential to waste bits
VBR makes a better use of bits

Apart from the datarate the only things that make it 'better' are the source and the encoding application and CODEC.
