I want you to try something. Because the DCT precision in this CODEC is only 8 bits, change ALL values on the INTER portion (right side) of the matrix to "16" (the standard values for MPEG inter values).
So now the "KVCD Notch Matrix" will work only on the INTRA part.
Your encoding speed will now be lower (more frequencies are now being encoded), but the quality and MAX bitrate should be higher.
Tell me your results
Did anyone try this??

Thank You.

Yep. I did.
Result is larger file size, for the same quality.
BTW, that post was before we changed the encoding mode.
