"i think he means that even if you set the bitrate to maximum you won't reach the quality of the dvd source. " Yup, that's what I ment,.. The main thing that bugs me, is that u still got rinning&co with yout encodes, even if u set the codec to max quality or the file turns out to be undersized (if u aim for a 2 CD rip, which I normaly do). The thing is 3ivX produces a bigger file at max quality than xvid, but it also kills ringing, color/wall_movement,... Cu Selur Ps.: about the flaskmpeg thing: 1st I'm an admin of the flaskmpeg.info/baord (german) 2nd flask isn't so bad, atleast the newest version 3rd I used GordianKnot to create the avs file and Virtual Dub Mod for encoding,... 4th I'm also a mod at the doom9.de forum; so may be I'm not a total noob ;)

I did,.. :) And I just tested another movie and had to realise that not all the movement is gone, but it's a lot less visible than with xvid. Cu Selur

Has anybody already made a test with xvid at quant 1? Are we talking max bitrates or not?

I haven't used quant 1 for a pretty long time ... In the past, speak some months ago, I found quant 1 to be buggy sometimes, for no obvious reason. And since I saw no need for the resulting extreme bitrate, I didn't investigate since then. Are the quant1's bugfree now?

I just selected,. quality = 100%, so it could be that xvid will still use quant 2,.. will test taht tomorrow (when I get home) "Are the quant1's bugfree now?" Thought it just produced an unresonable amount of data,... Cu Selur

Hmm,.. I did also test mpeg & all features of, and there was still some ringing around the cable at Morpheus head (where Morpheus is 'questioned' by Agent Smith). Thx for the info about the different matrixes, totaly forgot them,.. (tested them a while back, but never at max quality) Cu Selur /edit: just did some test, and I really like the hvs-best-picture matrix it helped a bit, but the real quality boos came with doing a 1pass-quantizer=1 encode, earlier I did a 1pass-quality = 100% encode and so I had to realize that quality=100% isn't the same as quantizer=1 (which I thought), it matches quantizer=1) So the next question is? Is quantizer 1 buggy, and if not why isn't it used to prevend undersized files? If it is buggy, could someone plz fix it? edit/ /edit2: mfluder you are my man of the day, I finally found a way to produce the quality I like: hvs-best-picture + 1pass-quantizer=1 + bframes(3/150/100)+ chroma motion + qpel + dynamic hpel/qpel; at least for the scene where morpheus is questionend (matrix chapter 28), this really is how I like it,.. :D edit2/

@Selur IMO it's an overkill to use quant 1. You'll get much much bigger filesize which is not worth the quality improvement. Also, there is a problem of a CPU usage. It's much higher when decoding a file encoded with quant 1. And most important thing is that quant 1 is buggy with current builds due to TOOSMALL_LIMIT set to 1. This will be resolved when new API is finished by setting TOOSMALL_LIMIT to higher value for quant=1 and to 1 for quantizers higher than 1. I suggest that you use quant 2 and try to find a matrix that fits your needs. If you can't find one than try making one yourself. That way you'll also learn some things about quantization. mfluder
