Would it be possible for any of you put up a mirror somewhere. I haven't been able to download the binaries for more than a day. Very frustrating!

Introducing editing functions into meGUi would hugely add to the complexity (as you need to maintain sync with the audio) and is completely unessecary as there are other tools that do the job. |

Maybe those apps have improved but compared to the application I use to cut I found those apps much of a pain last time I've tried.

Fixed quant XviD encoding
Is it possible in MeGui to do a fixed quant XviD encode using a quantizer that isn't a whole number?
It seems to work fine from command line but I'm not having a lot of success in MeGui. |

and what would 2.5 result in? 50% 2 and 50% 3? Don't tell me there's 2.5 quantizer I'm unaware off (and for that matter the XviD status window)

I just recently started to play with advanced codec settings so I'm pretty much clueless. I made however a quick XviD test, there appear to be a file size/quality difference:
Code:
q4 = 2.89 MB q3.5 = 3.75 MB q3 = 4.13 MB q2.5 = 6.28 MB q2 = 6.76 MB

Yes, XviD dithers the quants, 50% q2 and 50% q3.
lavc allows a qscale=2.5, and really does it (rounds to the nearest integer quant, but tweaks RD and trellis to get a quality point halfway between qscale=2 and qscale=3). stax: Notice how your q2.5 is nowhere near halfway between q2 and q3. That's because the q3 half of the frames are lower quality, but most of the details missed there just have to be encoded in the next q2 frame. So overall you don't save many bits, and just lose a little compression efficiency. Last edited by akupenguin; 27th December 2005 at 13:44. |

AutoGK uses this approach when you choose 'Target Quality' mode. 75% quality equals quant 2.67, 67% equals quant 2.99 and so forth... It's really nice to do 1-pass encodes when your hardware isn't exactly state-of-the-art and file size isn't an issue.
I've been doing 2.67 quant encodes through VDubMod for a while and I just thought I'd ask since MeGUI looks really good to me... :-) |

well, it's no problem changing those up/down boxes. I don't see the sense of 1 pass encoding *at all* but it's no problem to make the change.

I use always single pass quality mode. Regarding multipass vs quality mode I started a thread recently. While there were great answers and help I'm still much interested in other peoples opinion on the topic, it can be found here:

how do you calculate the proper q amount (based on input resolution?)? |
