Visualization of Bitrate distribution in VirtualDub

[senze]

I can't find the option in Virtual Dub to show me the bitrate distribution of my video file.

If there isn't any, so is there a good tool for free which lets me analyse the bitrate distribution?

I imagine this:
x axis: Frame n
y axis: framesize of Frame n in kbytes

You can try bitrate viewer , but I don't think it will show you framesize of each frame

FFDShow's OSD can show coded frame size along with bunch of other information, you can print it out on .csv for excel, spreadsheet etc...
