But comparing one raw frame to an encoded frame won't tell you the whole story because a lot of H264's magic juice comes with moving images.
It depends on what your station broadcasts at, you are probably broadcasting at 10-15mb/s mpeg4 720p. I would say that a 10mb/s 720p x264 encoded video would be noticeably better quality if its coming from a raw source. Heck if you are coming from a clean source I bet you could get away with a smaller bitrate, play with the constant quality setting on handbrake until you find something that is acceptable for you.

It sure has been fun testing all these encoders this weekend and learning as much as I can about this, I shoot for two stations and one is cable only and that's who this project is for so there are also limitations on what rate the cable and satellite companies transmit stations signals at and of course internal compression applied in their editing software to save space as well and those values I don't know, I haven't asked yet.
It's also good to remember that I am not using a pro-encoder yet trying to achieve broadcast grade results in small file sizes so that could be why none of the other converters I've tried have come even close.
Handbrake in high profile mode at least on my monitor here at home seems to be showing me quality as good as the original file and nearly half the file size, good results in video containing fast motion as well.
Still have to use Vegas to capture and make the original file though but so far so good, the idea of being able to have handbrake automatically convert everything in one folder and dump in into another folder for ftp'ing is nice but that's out of my league right now.
