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 :wink: )? |

@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? |
Good morning Audioslave :)
I'm using MEncoder dev-CVS-040430-00:00-3.3.1 (C) 2000-2004 MPlayer Team -kwag |
Thanks again! :D

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

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 ;-) |

704/352 = 2. But 720/352 is not even :!: Isn't resizing a bitch :lol: -kwag |

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 |

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

Hi all :D .
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 ( :x ), 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 :lol: ) Thanx in advance |

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: Code:
SCALE, CROP, unsharp=l3x3:0.6,hqdn3d=3:6:2,unsharp=l3x3:-0.7:c3x3:-1.5,noise=2th, EXPAND Code:
vhq 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.

No problems with your audio?
