@kwag
So this command should be able to deal with hybrid material too I guess?
Could you please post your *.bat file (2 pass of course )?

@kwag
Thanks a lot, Maestro! I just came out of bed and saw your new discovery, helpful indeed.

BTW Which version of MEncoder do you use?

And thats the point why only a crop detection is very risky:

This will end up in a wrong AR! (headache! )

IF you go from 720 width to PAR 128/117 (no matter if overscan will be added) means in this case to a 352 width you have to crop the width by 8 before IF u use cropping as first command!

crop=704:460:0:6,scale=336:320,...........,expand= 352:480

Yes you're right
704/352 = 2. But 720/352 is not even

Isn't resizing a bitch

-kwag

yes, bitch is always "too large"!

Actually the correct line for "Back to the Future" is: vf=yuvcsp,pullup,softskip,crop=704:460:0:6,scale=3 36:336,hqdn3d,sab=.5:.5:1,noise=1th,expand=352:480

The original is 1.85:1

-kwag

Can pullup and softskip to be included in any script, no matter source type (DVD or AVI), or source fps (23.976, 29.976, 25), or telecined, or progressive?
When it must to be present in the script?

@Kwag: I already read that, but i don't understand it. I'm sorry. It is too technic for my english.

Hi all .
Hi Kwag. Already tested your MA mencoder filter chain. With a resolution 704x576, it slowed mencoder to 4-5 fps (you already advised it).
I wanted to compare it with mencoderAVS, but after upgrading my PC (a big 160 GB HDD) mencoderAVS is not working for me ( ), even avisynth is working OK. I still have to compare it (speed) with makeavis way... and with vmesquita filter chain (image quality).
But this filter chain would work more like hybridfupp than MA (in a way), since it just blurs some portions of the picture, am I wrong?.
Other thing I'm curious (sorry, it's OT): from your last posts in this thread, I can see you're using a different approach related to mencoder parameters
- using mbd=1 (vhq), we were using default mbd=0. I didn't compare them. Is it slower?. Does it improve quality (it's supposed to)?. It's even better with mbd=2, but sloooow.
- you dropped vqblur=0 (so you're using default 0.5). With vqblur=0 mencoder is supposed to raise quantizer immediately whenever it's needed; with vqblur=0.5 quantizers are averaged with previous values. Why do you want mencoder to do so?, in what way does it improve the stream?.
- you're using scplx_mask=0.01, very little mask is applied. scplx_mask is used with deblocking purpose. Does it mean that the filter chain is enough to avoid blocks?, does it make mencodings faster?.
- finally, you're using a lmin=0.01 value. I tested really low values earlier (0.1), not so low, and with them I got a planar Q curve, as when using vqscale. And it also made bitrate peaks raise a lot. What's your purpose when using this very low value?, don't you get a planar Q curve, and high bitrate peaks?.
Kwag, I make all this questions to learn from your experience. Sorry if I did too much questions, but I want to understand your way. And as I don't have much time now to test, I need you tell us the result of your way (even there's already a sample to see the result )
Thanx in advance

No you're not wrong Yes. Yes. To avoid the spikes that many people were seeing. I got better results with that low mask value. Remember, these are values I'm experimenting with, so take them with a grain of salt No. With the value I have set lmin and scplx_min, I'm getting better bitrate distribution. Nope. No crazy peaks at all, and bitrate within the MAX limits every time No problem

-kwag

Already tested your MA mencoder filter chain.

The quality is good, but it is very very slow in PCs < 1 GHz.

I look for another chain alternative with decent quality:

An removing It could be this? It is the last propose chain before the current MA.
I can optimize something this?

Thanks.

-Maurus

Same problem here: two slow. I've got an athlon xp 2400 and with this script i've got only 10 fps and with 2 pass it takes 8 or 9 hours. The quality is very good but I can't wait so long.

Is anyone getting buffer underflows in mencoder with these filters? I get alot of them and the audio isn't sync anymore after half an hour Reducing the noise to 1th has helped a bit with the buffer underflows in mencoder but the bitrate drops below 200

I allways (with this filter chain and with all filters chain than I try) get a lot of "buffer underflowin", but in the PC and in the player the KSVCD seems good.

-Maurus

No problems with your audio?
