8O I never had a peak of over ~8,500, when using KVCD's Q matrix :!:
Is that at 704x576 :?:
Maybe that's why, because at 704x480, I never reach the MAX (for DVD) which is ~9,000Kbps (9,800?, don't...

No, haven't tried that yet :lol:
What I'm going to try in a little while, is encoding one of my Panasonic DMR-E80 captures, to see how it looks :cool:

Because every sample I've done (posted), looks far worse when done with TMPEG, at the same file size :!: :!:

I'm trying to find a way to encode with 9 bits precision, but that's probably impossible at this moment :)

I'll answer that.
*** NO ***
The CBR bitrate value controls the size of the VBV buffer size.
Leave the values that I posted on the procedure to make KVCDs or KDVDs.

Edit: Correction. You can...

It has to 8O
For example, start with all values set to 2.
If file is too large, change them ALL to 3. Etc, etc.
The higher the numbers, the lower the file size.
Works for me :!:

Good news, and new finding :D

The problem with the matrix, and ffvfw, has been solved :!:

This will fix the VBV buffer size to 112, as shown in...

When using lower resolutions, like 352x480(576) or 480x480(576), you won't get peaks of ~8,000.
They will be arounf half (~4,000).
You might want to use the notch matrix at these resolutions, and...

Hi Inc,

Remember that almost every one of those matrixes (high frequencies), will be truncated by ffvfw :!:
The MAX value for ffvfw is 63, so most of those matrixes will be useless with ffvfw.

You can drop the file size, either by lowering the MIN Q value, or by lowering the Bitrate in CBR, as you have done.
As a matter of fact, I'm looking at that just right now, and it seems that the...

High frequency details. Only on fast motion scenes, you'll see (maybe?) some macroblocks, because of bitrate choke.
You'll have to do some short clip tests by yourself, with and without the matrix,...
