How do i compress test AFTER avisynth filtering?

[Stigma]

A simple question, one im sure has been asked before, but i was unable to find it with extensive searching:

How can i get a compress test something so i get a value that is correct for the video AFTER avisynth filtering? The normal Gknot compres test is useless, because after i de-noise and re-sharpen the compression number has completely changed.

Again i apoogize if someone has asked this before.

You do it manually. This may or may not work, but it will give you the main points, as this is from memory.

Assuming DivX 5: Edit the .avs the way you want it.
Remove the comment "#" in front of the SelectEvery command. (5% of the content, by default.)
Save the .avs file.
Open the .avs in Virtual Dub.
Set video to Fast Recompress.
Set Video Compression to DivX 5 (or DivX 5 Pro, if you have that installed instead). Don't close the compression window!
Click on the Configure button.
Now that the DivX5 configuration GUI is open, set to 2 pass encoding, first pass
Set the bitrate to 10000, which is the maximum.
Set the logfile name so that it ends with _AAAxBBB.log, where AAAxBBB is the resolution of your .avs resizing.
Set all other DivX 5 parameters you want, such as B-frames, GMC, etc.
Close the DivX5 configuration window.
Close the compression window.
Save as .avi
Wait for first pass to complete.
Exit Virtual Dub, return to Gknot.
Press "Load" button at bottom of Gknot window.
Select log file you named in the DivX configuration window.

DVX also makes the comp test with the script in the script editor, works with any source type supported by AviSynth
