My encoding speed. Good or bad?

[Toejam]

I am endcoding with XMPEG at about 16 fps.
I am using the DivX 4.12 codec and MP3 sound at 128 kbps
I left the default options (1pass, 1000kbps, best quality)

I have an Athlon XP 1600 (1.4GHz) w/ 512 MB DDR RAM

Is 16 fps normal, or shouldn't I be getting faster?

[Zarni]

I would say that it can be about normal for me ( running a 1600+ on 256DDR), but it proablby has alot to do with the filter you are using, you could try and use the bressenham filter, that noramly gets me to over 20fps, but I mainly use 2pass mode ( I really should do 1pass more to test the quailty/filesize)

I have had it over 30 though with a bit messing around and only bringing the quality down a little bit.

I'll be damned if I can get a decent aduiio level out of Xmpeg though, and has anyone noticed ANY difference with the postprocessing slider ?! seems to do nothing for me.

Later..

It was a 400 x 320 rip, by the way, in case that matters. Is the bressenham filter in Global options?

Yes, I've also noticed the audio is a bit too quiet. Can't do anything about that?

Kind of lame that there is a luminance option, but not a volume option, since the two are analogous with video and audio.

[xzquala]

the post processing slider just sets the default level of post processing in an avi. it is strongly encouraged by me to either set it to 0, or the lowest, whatever its called. post processing is for playback, not druing compression, so it won't affect compression speeds. it basically smoothes the video, so you don't see compression artifacts and the like. EVIL, I don't like smoothing, I like my detail.

as for the sound, you can easily do the sound normalizing in gknot. you can easily do everything in gknot. just use gknot, you will even have better quality audio since it uses the best audio tools out there.

BOO to toe-ey!

should be getting a bit higher than 16fps... though it depends on what idct your using.

[Toejam]

What does IDCT mean?

[Master PooBaa]

maybe i spelt it wrong. its them things u use to encode.
u know
dvd2ave mmxsse
amd x87
amd 3dnow
etcetc

[Toejam]

Vids look great, so oh well.

Something about my processor eh? Well, I bought the Palomino brand AMD Athlon XP, so I figured it would be top quality. Oh well.

iDCT = Inverse Discrete Cosine Transform

MPEG uses DCT to translate spatial information (the images we see) into frequency information (compressed). To bring back the spatial info from the MPEG stream you need to apply an Inverse Discrete Cosine Transform.

BTW which iDCT is faster for you? Im using Miha's Fast Integer one but that is because it has the word "fast" in it...:-P

I don't truly know the difference, is there any place explaining that? or do any1 know?

Thx

[Master PooBaa]

i just use the default DVD2AVI MMX one
it seems to be faster than all the others, even the AMD optimised ones.

actually ive gone off xmpeg... kept crashing. im trying gordian knot now. made a great movie, but it had no sound LOL
maybe i should READ the instructions hehehe

[Master PooBaa]

P.S. has anyone worked out how to do full sized movies on flask xmpeg 4.2a? i.e. input file size over 4gb? (yes im using ntfs)

[Zarni]

p.s. well PooBaa, I tried it,
couldn't get it to work,
couldn't be bothered to find out why,
rip everything to 3.5GB files that way just about everything works out to 2 vobs, no real problem.
One of the reasons I gave up is that windvd didn't like playing 4GB vobs either and as everything automaticaly pics up the second vob why worry :)
