wrong mp3 conversion

[arnoo]

hi

got a big problem since few days
I've an ac3 files :
AC3(6Ch) 48kHz ] [PTS 0:00:52] [Delay -8 ms] [@4] [448 kb/s]
Length : 1h26

When i try to convert in mp3, using headAc3He, besweet....,
I obtain always a 30min mp3 with 70M!!!!

If i try to convert in ogg or wave, no problem, good length .
But in mp3, always the same problem
I've tried to use vbr in old routine, always 30min length

This mp3, when i play it with WMP, indicate a bitrate of ~400kb/s....


Thanks for all your idea
and sorry for my really bad english....

(I've took this example, but same problems with ALL ac3/mp3 conversion)

[DSPguru]

according to BeSweet's logfile, the track length is correct (1:26:28), and avg bitrate is correct (127kbps)
i believe this isn't a problem with your encoded track, it's just wrong information supplied by wmp.
try to playback the mp3 on winamp, and you'll see the proper info.

[arnoo]

but when i play it, it's really 30min sound
and it's really the first 30min of my track
So....

[arnoo]

yeeeeeeeeeeeeeeeeeeees
i'm a big shit.............
You're right
it was wrong information with WMP
Winamp understand my mp3 and I!!
But before, i ve got right information, good lenght and good bitrate
So, what's the matter with wmp?

May I change my command line to improve my mp3 (even if it sounds good)

Thanks for your good idea

Thanks for your good idea for faster two-pass use :
d:\Video\DVD\DVD-RIP\RIPDIVX4\Besweet0.9\BeSweet.exe -core( -input d:\Divx\Rip\poucet.ac3 -output d:\Divx\Rip\piste1.mp3 -logfile D:\Video\DVD\DVD-RIP\RIPDIVX4\Besweet0.9\BeSweet.log ) -azid( -s surround -c normal -g max -L 1 ) -ota( -d -8 ) -lame( --alt-preset 128 )

for fastest transcoding, use one-pass :
d:\Video\DVD\DVD-RIP\RIPDIVX4\Besweet0.9\BeSweet.exe -core( -input d:\Divx\Rip\poucet.ac3 -output d:\Divx\Rip\piste1.mp3 -logfile D:\Video\DVD\DVD-RIP\RIPDIVX4\Besweet0.9\BeSweet.log ) -azid( -s surround -c normal -L 1 ) -ota( -d -8 -G max ) -lame( --alt-preset 128 --scale 1 )

as for the dynamic-range-compression rate - have it your way. i prefer light compression...

Ok DG
I will try the both
Thanks for your really great forum and for the best divx site in the universe

And for really kickass quality you can use this parameters for lame: --nspsytune --vbr-mtrh -V1 -mj -h -b96 --lowpass 19.5 --athtype 3 --ns-sfb21 2 -Z --scale 0.98 -X0

It will give you an average bitrate of about 175kbits/s (vbr)sometimes more sometimes less. (source is http://www.r3mix.net/

i've post my question in 3 differents forums.
You're the only one who really understand this very little little little problem....
with a fast reply!!
That's why I said this forum is the best for divx...

So, for the parameters, I just have to change the --alt preset with (--nspsytune....) and that's all?????
I will have this with besweet:

d:\Video\DVD\DVD-RIP\RIPDIVX4\Besweet0.9\BeSweet.exe -core( -input d:\Divx\Rip\poucet.ac3 -output d:\Divx\Rip\piste1.mp3 -logfile D:\Video\DVD\DVD-RIP\RIPDIVX4\Besweet0.9\BeSweet.log ) -azid( -s surround -c normal -g max -L 1 ) -ota( -d -8 ) -lame(--nspsytune --vbr-mtrh -V1 -mj -h -b96 --lowpass 19.5 --athtype 3 --ns-sfb21 2 -Z --scale 0.98 -X0 ) :confused: :confused:

Thanks a lot
