No for the moment....
I use Mplex or bbMpeg for muxing. -Maurus |
The weird thing is that I'm not getting underflows while muxing with mplex
|
With Mplex the error is under-runs, not owerflows (that is in MEncoder).
I get a lot of overflows in MEncoder and not usually over-runs in MPlex. -Maurus |

I get a lot of overflows with this settings:
Code:
480x576, vrc_maxrate=2500:keyint=15:vrc_buf_size=917 Code:
yuvcsp,scale=480:432::0:9,crop=448:432:16:0,hqdn3d,sab=.5:.5:1,noise=2th,expand=480:576:16:72 -Maurus |

Drop "sab" from the filter chain. 2 movies (~4 hours without adaptive filtering) on one DVD is just fine with the "notch" matrix ;) -kwag |
Thanx a lot for your clear answer Kwag. Just a few questions:
Quote:
I read somewhere that vratetol lower values would make bitrate more "stable" (even vratetol=0 would be like constant bitrate), I still have to test some values. Quote:
If I find the time I'll do some tests just tweaking vqblur and vratetol, and see its effects... and post in another thread, since this is all OT. Sorry. Well, please tell me what do you think about this. Cheers |
Thanks Kwag
So my parameters should be something like that? Code:
vf=yuvcsp,scale=688:414:0:0:60,crop=718:576:-1:-1,hqdn3d,noise=3th,expand=704:576:-1:-1:1 |

Ok, thanks again.
And just to be sure, my command line Code:
2240 |
That's it :)
|
My resolution is 704x480 I'm using pullup and softskip to convert from 29,97 to 23,976.
Keaping the fps at 29,97 gives the same error with audio not being sync after a while :P . I've encoded this DVD about 7 times now :? Would lowering the resolution help? I'm doing skvcd so vbv=917 -Koekies Edit: and max bitrate is 2200 |

-kwag |
but that's dvd will would your standalone still be able to play it?
Because one of my dvd players isn't even able to play back my skvcds made with mencoder :? And they're both philips :P Should I lower ther resolution? Or would that lower the quality? -Koekies |

The more I work with it, the more in love mencoder :lol:
Just finished a full encode of "Back to the Future", and I'm :rotf: with the quality :D Take a look: http://www.kvcd.net/bttf.mpg.cut.45.mpg ( ~10MB MPEG-2 pulled down, 37 seconds @704x480 (2 blocks overscan), clip has audio) I encoded for KDVD and my complete muxed size is 1,683,362KB I still have to encode part 2 and part 3, because my goal is to put the trilogy on one DVD-R. But I'm right on target, and they all should look like that sample :) Again, no underrun errors, with the current settings. Here are some screenshots of the film: http://www.digitalfaq.com/archives/i.../2004/06/8.png http://www.digitalfaq.com/archives/i.../2004/06/9.png http://www.digitalfaq.com/archives/i...2004/06/10.png And here's a close up from another scene, for some details: http://www.digitalfaq.com/archives/i...2004/06/11.png -kwag |
Karl those screenshots look awesome I hope you pull off getting them all to one DVD as I want to do the same with my Trilogy box set.
The mpeg I downloaded look excellent quality wise also. Nice work Karl. :) |
Thanks Zyphon,
Yes, all three movies should fit "tightly" on one DVD :D I haven't had time to encode the other two movies, but I'll probably do that in the weekend. I'm still fooling aroung with shape adaptive blur settings, so the ones I used are not final. But so far, I'm very pleased with the results. :) -kwag |

FYI, Marty's anti-rad jacket on the second snap is supposed to be yellow. A plain, uniform, bright, yellow tint. Not this undefined grainy green-yellowish things you can see on mencoder output :puke: Same (but less visible) for the color of the terrorists' pickup on third snaphot. I'm currently DL the sample... stay tuned ! Edit: Okay, let's go for a quick comment ! Grainy, grainy, grainy. :puke: :puke: :puke: Look at Marty's face when he closes the DeLorean's door (sec 6). Look at his jacket when he is driving and his arm just after (sec 16 to 18 ), look at the terrorist faces also. In one words : ANYTHING is like if a sand strom passed in front of the camera while they were shooting. Note: I only speak about the bad things. "forgetting" the good ones (for instance there is absolutly no mosquitoes despite the resolution and target size and only few pixelated part). But personally I can't really stand watching a whole movie like this. The only idea that comes in mind watching that is "this video need a GOOD denoiser" :!: |

I think you haven't seen the original VOBs :!: They are worse :!: I'll post a screenshot, so you can compare, and then maybe you'll see the difference ;) -kwag |
Here's your answer Phil ;)
Original Anamorphic VOB: Edit: Talk about a BAD quality DVD :? http://www.digitalfaq.com/archives/i...2004/06/12.png 4:3 Letterboxed KDVD: http://www.digitalfaq.com/archives/i.../2004/06/9.png Edit: I think mencoder filters are doing a pretty damn good job :) Second comparison: VOB: http://www.digitalfaq.com/archives/i...2004/06/13.png KDVD: http://www.digitalfaq.com/archives/i...2004/06/11.png -kwag |
Whoaow. You definitely need the THX-labelized PAL release then :-).
This source is AWFULL :-D Okay, mencoder did "what it could" on that, I have to admit. Just to know : how many underflows error message for the whole movie ? And time to encode ? |

The next code was not my final mux. That's the mux I did with an MP2 audio I had already encoded at 44.1Khz. The sample you download has 44.1 audio, My final mux was with AC3 audio. :) Code:
Scanning video stream for a sequence header and pulldown type ... -kwag |
@kwag
Well, I don't know how you do it but I'm still getting underflows! :cry: I'm using the setting you posted a few pages earlier... BTW Where can I download the MEncoder version you're using? |
Quote:
There is only ONE denoiser implemented in mencoder and it's easy to understand that you can't fix all situation with so few. It's like if avisynth script were limited to Deen or Convolution3D. Mencoder misses also a good temporal only filter. |
Quote:
The encoded sample looks MUCH better :!: Quote:
-kwag |
Yes Kwag, the images you post are impressive.
They're from KDVD, aren't they?. I see you use maxrate=5000, what's your maximum bitrate for this KDVD?. I ask because I tested your command-line, with a DVD source and for SKVCD output, and yes, the filter chain really clean nice the film, but with a maxrate=2500 I get peak of 4014 in BitrateViewer :( . I posted here, in this same thread some questions I have about your mencoder parameters, but I'm afraid you missed that post. What's going wrong?, is it the source?, is it that I encode at 704x576 (used noise=2th)?. How, do you think, can I control those too high bitrate peaks?. Thanx for your help. |

Didn't you just said you encoded for SKVCD output :?: Quote:

Note : I find your script lost a LOT of details in the bald skrull of the guy on the left (don't remember his name) on the third snap. Marty's face is correctly denoised but this is done with too much sacrifice. Quote:
But with avisynth... |

I'm not done with the filter chain yet ;) -kwag |

I'm pretty sure the difference will be minimal, and the encoding time to achieve at least the same, will be much longer. It's a fact that mencoder's internal filters are much faster than AviSynth. So for me, I'm very pleased with those results, just as they are :!: Can they be improved :?: Of course :!: Is it worth it :?: Of course :!: But there will be a price to pay, which usually turns out to be "time". -kwag |
Quote:
You admitted yourself that the new line dropped the speed by two ! This added to the 2pass encoding I'm sure you have now an encoding time longer than tmpgenc ! I already have this with a coding line issued from packshot and it doesn't use sab :!: Encoding time under mencoder : 6h per pass Encoding time under tmpgenc : 10h :!: With all your filters you gave a long kiss goodbye to the speed benifit and you know it. You can do the test on BTFF by yourself. Reinstalling tmpgenc does not take so long ;-) |
Is the MA avisynth script and mencoder really that slow?
Is the quality better than with tmpgenc? If it's only a bit slower you could just use that because waiting 12 hours for an encode or 14 isn't that big a deal :P |

Quote:
But in this case, the question to know if tmpgenc will be faster or not is not even needed to be asked :-P Quote:

What I mean is I'm encoding mpeg2, 25 fps, 704x576 res, with maxrate=2500 and avg=1230. Quote:
So, just nothing to do about it, isn't it?. It's sad not having to do nothing to sort it out. Even more, when all my previous tests (3 DVD sources, 2 AVI sources and a home made film: my older son) went OK without a problem. And suddenly, in my last 3 DVD sources, this :!: . :( I hope you find a way for PAL users... |
I asked if the quality is better because tmpgenc is faster and it would be a waste of time encoding it in mencoder then wouldn't it
unless the quality is better. |

For the speed, my experiences have already proved that. For the quality, only a direct comparison can give the answer. |
