Very long to convert

[bambam]

I try to convert a divx file to a svcd
this if the original file info :
***************
File : 689 MB (689 MB), duration: 1:16:03, type: AVI, 1 audio stream(s), quality: 47 %

Video : 618 MB, 1136 Kbps, 23.976 fps, 512*384 (4:3), DIV3 = DivX v3 MPEG-4 (Low-Motion), Supported

Audio : 71 MB, 131 Kbps, 48000 Hz, 2 channels, 0x55 = Lame MP3, Supported
***************

When i try to converting, it took about 33 hours and it was just around 29% of the conversion. It normally take me around 6-8 hours to convert this kind of file. Does anyone have an ideo why it was so long ?

What program are you using to convert it?
What bitrate are you attempting to use?
Have you applied any filters to the output?
Is it multiple pass encoding?
What other things are you doing on the computer at the same time?

>What program are you using to convert it?
TMPGEnc

>What bitrate are you attempting to use?
750 kbits/sec

>Have you applied any filters to the output?
I don't know what it is, so if the software don't put any i don't think so

>Is it multiple pass encoding?
What is multiple pass encoding ?

>What other things are you doing on the computer at the same time?
I was not home so almost nothing (the same thing as when i convert others movies in 6-8 hours


Do you have any clue ?

TMPGEnc isn't the fastest anyhow, but there's just too many factors involved, to make a reasonable guess.
Here are some of the things involved in how much time it's going to take:
CPU Speed.
Amount of free physical RAM.
Source size/bitrate.
Product size/bitrate.
All the settings in TMPGEnc.
Anti-virus scanner active.
Operating system.
Source drive/partition.
Destination drive/partition.

Give us some more details.

750 kbits/sec

Abort. It will look like s***t anyway. You need at least twice as high bit rate, preferably thrice as high for a good SVCD.
That said, 33hrs for 22 min encoding seems extremely slow for anything above Amiga... Did you use the std SVCD template/Wizard?
Setting the motion search precision to Highest might explain this kind of encoding times, but even so...

750 kbits/sec was the value proposed to my bu TMPGEnc
so your telling me that i should put around the double ?

I have a P3 1Ghz
400mb of ram
Source size/bitrate : 1136 Kbps
Product size/bitrate.: 750 kbits/sec
All the settings in TMPGEnc. : by default
Anti-virus scanner active. : norton yes
Operating system. : windows xp
Source drive/partition. : 3 Gb free space
Destination drive/partition. : same one 3 Gb free space

You should do 2 things:

1) read up on GUIDES regarding TMPGENc and it's usage
2) use a bitrate calculator to determine your bitrate

For anything that you will be encoding in MPEG2 format, I do not recommend going any lower than 2400 kbits. MPEG1 standard is 1150. Maybe if you need a bitrate as low as was stated in a previous post, you might want to look into encoding VCD instead of SVCD/DVD.

Turn off Norton while doing your conversions. This should free up a ton of RAM for the program(s) to use.
SVCD output on an .avi that's as big as yours (689 meg) will result in an mpeg about 2.5 gig in size (depending on bitrate).
Using TMPGEnc, this is definitely going to take some time, even with a very poor quality setting of 750kbps.
Here's what I would do:
1.) Split the file into 2 equal parts.
2.) Using the Bitrate Calculator, Open TMPGEnc, and set the bitrate to 2520 CBR. Set the Motion Search to Normal, or HQ (slow).
3.) As your original is 23.976fps, encode the mpeg at the same fps. I hope your DVD player can play at that speed, otherwise you're going to have to convert it to 29.97 SVCD standard (see the guides).
4.) You should end up with about a 780 meg mpeg in SVCD standard for each half, ready to burn.

Ok i try to extract the sound with virtualdub in a wav file. Then encode the mpg file with the avi for video and wav for audio track. It seem to go faster (approx time 8 hours) which is much more normal. So i hope it will work
Thank you very much for your advice
I appreciate
