Is there a program that will show the encoded Y'CbCr values?

[Owe]

Hello VideoHelp!

I need help finding a program that will allow me to something I at first thought would be very simple. I want to be able see what the encoded luma and chroma values of an area of a frame is. The movies are from a Canon EOS 550D / T2i camera and are MPEG-4 AVC encoded QuickTime files. You can rename them MP4 and they will still play BTW.

I've been trying out Color a bit but I can not get it to show show encoded values, and I can't find any reference as to how the displayed values are derived so it's no use.
I have found two programs that will seem to show encoded values, YUVTools and CodecVisa, but I can not get it to work with the cameras files. I've tried converting them to .MP4 and.h264 using YAMB but to no avail. I've also searched around the net a bit but I've been unable to find any discussions about extracting raw values so I don't know what to do next. I thought this would be a common desire, but it seems not.

What I want is very basic; you select a frame, put the cursor over a pixel/select corodinates and its encoded value is displayed. Displaying luma and chroma channels separetly and giving averages for several pixels is a bonus but not neccessary. Crude is fine, text based is fine, just anything that will show me encoded values and you don't have to be a programmer to operate.

DP Review has some sample clips if you need them.

Can anyone give me out here? I feel like I'm completly stuck.

Normally, one would use a Waveform Monitor to view luminance and a RGB parade or Vectorscope to view chroma. These are included in typical editors (Final Cut Pro, Preemiere Pro, Vegas Pro).

h264visa works for Canon 7d , I don't see why it won't work for T2i.

Extract to raw elementary stream with yamb, as it doesn't work with mov container

EDIT: is codecvisa a new program ? it looks exactly like the old h264visa ?

I downloaded bus.mov from that website, and it works fine in h264visa
