KVCD settings for QuEnc v0.53?
Howdy,
Can anyone clue me in on how to use the KVCD notch matrix in QuEnc? I just downloaded v0.53, and it worked great for a short sample MPEG2 for standard SVCD (but it was 50 MB). I've read in threads here that I should just check the "use KVCD notch matrix" under "Advanced Options," but that option does not appear in v0.53. Is there a special version I need to download from somewhere? Something goin' on :?: -abs |
As far as im aware they removed the KVCD 'notch' matrix from version 0.53 which to me was a silly move as this was quite a good encoder until they did that. :?
Your better of Downloading Vmesquita's FreeEnc which is based on the same Libvacodec as QuEnc. |
Hi absinthe,
KVCD Notch matrix was removed from QuEnc because of some problems with trellis. As Zyphon already pointed, you can use my encoder "FreeEnc" which also uses the same library, libavcodec. :D |
Thanks, guys :D
I just gave QuEnc a shot on a KVCD sample and results were real good. By the time you read this, I'll be encoding with FreeEnc! ... -abs |

Did a 90-sec sample of a TV show from AVI in two passes. Quality was okay, but I didn't apply any filters at all. I wasn't sure where to set the bitrates, so I used 1500/2500.
All in all, I'm just amazed that there's a free encoder that actually works :D So, as I understand it, by default: 1 - It's an MPEG2 encoder only and 2 - It uses the 'K' notch matrix only (I assume that I was correct in clicking "Go" a second time to do the second pass ... it doesn't do it automatically?). Might try a whole 90-minute movie tonight with some script filters and see how it comes out .... 8) -abs |

Is there a good size prediction method ... I'd like to try a whole movie. -abs |
That's the good part :)
No need for file prediction. You just run Karl's Calcumatic and open your D2V file in it. Choose your target media, video and sound options. Click on the Calculate button and Calcumatic will give you an average bitrate figure. Use it in FreeENC and look how close your encoded movie gets to the needed file size if you run a 2-pass encoding ;-) Besides it's very fast! Cheers |

So now I know :o. Cool! Wish I had know earlier though. I just took a stab in the dark and plugged 2500 in for max and I think 1300 or so for average. I wasn't worried about going over because my movie was only 1 hour long. In fact the MPEG2 only came out to 411 MB. So it took quite a while to do 2 passes. Started about 9:45 p.m. and finished around 4 or 5 a.m. I used 352 x 576 PAL and just a few filters (Blockbuster x2, BlindPP, Convolution3D, Undot, TemporalSoften, and DCTFilter). Maybe the filters slowed things down a bit. bbMPEG muxed without a hitch, and VCDEasy didn't even hiccup on it! I'm watching it right now and I have to say it looks darn good! (especially if you consider my source material was crap 8)). My hat's off to the author! (Wonder if this thing does good on DVD material .... ?) -abs |
Hi absinthe,
Yeah! We need to congratulate VMesquita for giving us FreeEnc! :ole: Thanks VM :D :ole: Now, we are conducting experiments with it for KVCD/KDVD. For now, I must say that it is one of the best out there for KDVD. In terms of KVCD I think we'll need to tweak it a lot untill it gives as good results as tmpgenc does. But I'm sure we'll get there. BTW, don't expect lots of speed even on low resolutions when using those filters you mentioned. For instance conv3D can be a pain in the *** when talking about performance ;-). Cheers m8 |
FreeEnc forum is now open :)
Now we can forget about QuEnc (as it no longer supports our advanced matrix), and focus on the advanced features of FreeEnc ;) The new forum is here: http://www.kvcd.net/forum/viewforum.php?f=85 -kwag |
