H264 Encode from QT7 vs Compressor

So - it seems that setting the bitrate inside the Quicktime dialog - rather than just the Data Rate input results in the Minit example encoding correctly. I've thrown a few QT's at it, and i'm getting fairly similar file sizes to my QT7 encodes setting a 150000mbit/s bit rate this way. Going to throw a few more tests at it, but I think i've got this part somewhat solved.

There's visually more compression in the smaller file size, which is why i'm looking to get the max quality possible out of these H264 MOV's.

The data rate of the final MOV out of Compressor is 20.39Mbit/s and the one from QT7 is 142.97Mbit/s

Here's the screenshots comparing the output:

Is there any way to tell compressor to be less aggressive in it's encoding? I'd really like to find an automated way to get match QT7's output if possible.

So, just for curiosity's sake, for the previous MOV I was working with I set the encoding to 142000 kilobits in Compressor with all the other settings being the sane and Compressor output something that's comparable file size wise to the QT7 Target. The output was 1.53GB and the bitrate was 121.99 even though I specified 142.0

So, let's say ok fine - I'll just set a 150Mbit/s bitrate for my HQ encodes out of Compressor. Maybe that'll work, but let's throw another totally different example at it and see how it handles this. The results are pretty nuts and don't make sense to me at all.

Here's some screenshots and explanations.

The next trailer I tried throwing at it is a game with all 1-bit graphics - all black and white. Using the same preset with a 142000kb/s bitrate, compressor output a completely garbled and compressed mess compared to using the 'automatic' setting. (screenshot below QT7 encode on left and Compressor on the right)

Transcoding this same video using the same Automatic preset I was using earlier resulted in this final MOV being LARGER than the one I was working with earlier, which is totally counter intuitive 😮

As a side note - There's situations where i'm required to specify a very specific data rate for certain deliverables, and I was hoping I could use Compressor to automate a bit of this work, but if specifying a number doesn't give me that exact bitrate, i'm not really sure if this is going to work 😀 Any advice or thoughts on things I could try would be apprecaited!
