View Full Version : Is XviD Dead?

Edit:
I just found in my old notes that my recipe was for BRatio = 1.65 and BOffset = -0.25 (XViD defaults 1.5 and 1 respectively).
But don't quote me on that......
I haven't actually compared them for quality yet, but I ran a couple of quick encodes just to see what he effect would be. It certainly causes the encoder to spread the bits around differently, although in this case it also caused the encoder to miss the target bitrate (500kbps) by a bit more.

That you blocked Mick because he misspelled your name was the only plausible conclusion I could come to, as well.
Congratulations, mr. davidHORSE.
Another troll for my ignore list.

Trolling is so 90's. The only trolls left are the ones who accuse others of trolling.

Such as yourself, hullo_hullo.
Yes, some low-IQ people decide to harass me because of something THEY THINK that happened, and then I have no right to complain, otherwise I am the one to be called "troll". Your logic is amazing. The logic of the emotional manipulators. The truth is, the only trolls left are the ones who claim to be "rational".

I am a bit surprised to see the big difference in quantization which you got for the 2 settings. Maybe it's source specific. Are you positive that you used the same matrix?

Positive. I'm a bit short of time now, but I'll try again with a different source tomorrow and post the result.
Edit: Whoops, my bad. Thinking about it, I may have used BOffset = -2.5 instead of -0.25, being an idiot. I'll try again tomorrow. :)

Obviously I did have a stupid yesterday, here's the same test again with the same source.
I wouldn't even attempt to pick a quality winner at this stage as the source quality isn't all that high to begin with. I'll probably try again later with a much higher quality source. I can see frames are encoded differently, but at the moment they're mostly only a little different rather than better or worse as such.
