vfdct=3 (mmx) is the only one that works with the notch matrix.
And vfdct doesn't work with *bias negative values.

*bias negative values lower frame quantizers.
Reducing ibias decreases quality,...

It didn't improve, I was doing crap :?

But using vfdct=1:pbias=-256:ibias=144 I get similar size and quality to the notch matrix, without using the Notch matrix. :!:

And I could lower ibias...

I found a way to lower the quantizers on high-bitrates:

vfdct=1:ibias=-256:pbias=-256

you can replace vfdct=1 with 2 or 6, just not 3 (mmx) because it can't handle negative *bias values.

But...

libavcodec has gained MPEG-2 encoding only in the latest versions, it has been mainly used for MPEG-4 encoding.

What's strange is that if Michael is right, then there is no such thing as minrate in any DVD-compliant encoder. So how does CCE work? And TMPGEnc?

Could it be a muxing problem you had? :?

This is the main reason why I abandoned vrc_eq=avgTex and use only vrc_eq=tex. On bitrate peaks it overquantized.

It shouldn't happen with lmin=1.

But is it noticeable on TV? And how does lmin=2.49 + Notch compare to lmin=1 + your last matrices when watching on TV?

Difference is filesize:
