After doing some 75 - 100 KVCD projects with DVD2SVCD I'm following Dialhots advise to switch to manual procedure for Avi conversion projects.

After reading some threads about manual procedures for avi's can someone confirm if I understand this correctly/ If this still is the "correct" way to do it:

1. Use Virtual Dub to separate audio from video (save as .wav and avi)
2. Convert Wav to mp2 with HeadAC3he or BeSweet (I use HeadAC3HE)
3. Make a script in notepad (.avs file)
4. TMPGenc-> load KVCD template, Feed .avs file to TMPGenc as videosource - use ES Video only.
5 Multiplex with BBMpeg or TMPGenc (simple multiplex).

I've always used "trial and error" for CQ prediction, usually it takes me 2 encodes, sometimes 3. I can live with that. Will try CQ-matic later......

Looking forward to hearing your reply....

OK, I have separated audio from video (DIVX3 Low motion, 592x336) and I have a synched .srt file for the subs......

The .avi is in a 23.975 non standard frame rate.
How do I proceed keeping audio synched with video and getting the subs in my endresult ? (SKVCD - MPEG2 - CVD res).

Does this look OK ?

Code:
Avisource("D:\WorkDirectoryMovie\ExorsistVideoNoAudio.avi",true) 
BlindPP(cpu=4) 
Blockbuster(method="noise",detail_min=1,detail_max=3,variance=0.1,seed=1) 
Convolution3D(1, 6, 12, 6, 8, 2.8, 0) 
GripCrop(352,480,overscan=1, source_anamorphic=false) 
GripSize(resizer="LanczosResize") 
Undot() 
TemporalSoften(2,7,7,3,2) 
DCTFilter(1,1,1,1,1,1,0.5,0) 
GripBorders()
TextSub("D:\WorkDirectoryMovie\Subtitle.srt") 
AssumeFPS(23.976)
Specific questions: Is it correct to load the "NoAudio" avi and is "true" correct command to use in this case ?

How do you check position of subs with this "manual KVCD procedure" (D2S user -> still learning manual proc.... ).

The best for this is to feed tmpgenc with the video and the audio and let it encode both together. The result on the audio part is less efficient as when you use an external audio encoder, but you are sure that all will be in synch.

Yes it is. Just use "AssumeFPS(23.976,true)" to ask avisynth to keep audio in synch (that's the meaning of the ",true").

the "true" say to avisynth to decode both audio and video. If you do not have audio in the avi, setting "true" or "false" is the same.
But as I told you above, in your particular case you have to give to tmpgenc (and avisynth) an avi with audio.
Then you will need to put "true" at the end of avisource.

Do you remember the ".style" file ?

Ok.....I'm using the .avi with audio now and ",true" in the sourceline.

Also added ",true" to the AssumeFPS line........

Regarding the subs,......sure I remember the .style file. I use it all the time

I only wonder how previewing the settings of the style file works in the manual procedure, but I think I figured it out.......I'm using the preview function in TMPG. Although the window size is completely wrong of this preview window, It's more or less useful..........

OK, restarting again.............Oh, Oh......TMPGenc says this encode is going to take 32 hours (!!!) is that normal ?. I set the audio to resampling to 44.1 and 112 Kbps..........OK wait until tomorrow to see the result then.....hope filesize is OK.....

Regards...

You can also load the avs into virtualdub. Or play the avs in wmp

DO NTO RESAMPLE with tmpgenc. The audio encoder is quite slow and resampling if the most time eater operation. Can't you do kvcd with 48khz audio ?

You predicted the size with CQMatic without the audio before to put back the audio and launch the encoding ? It would be correct so.

.........I restarted encoding........This time without resampling to 44.1 Khz.......

It's worse than before ! Now it takes 52 hours according to TMPGenc.....

(I even rebooted my PC and have nothing else but Internet Explorer running.....)..

Any ideas ?

.....think it has may have something to do with the audio in the avi file. It's in "divx / wma" format.

Maybe TMPG doesn't like .wma audio ?

You probably right. I guess for DMA it needs to use a directshow procedure and that is always longer than the codec. I never did wma myself.
