i have encoded several divx movies using tmpgenc but the latest
one encodes without sound . i have not changed any settings.
i beleive tmpgenc is not the best for sound
any help appreciated

i had that problem before..do you kinow what sound the divx has?
mp3, ogg, ac3 or something else?

ac3 i presume , 48hz. all other divx movies i've had have been 44.1hz. also the filesize is 700mb but in the tmpgenc settings the movie is 263 minutes long . how can this be

i think you should extract the ac3 from the
movie with an other tool....i think virtual dub does the job

and then decode the video only with tmpgenc

Yeah, definitely do not use TMPG for audio.

TMPGenc does NOT have problems with WAV or MP3 audio, it just cannot handle VBR MP3 or AC3 audio now common in DivX files.

As suggested, use VirtualDUB to extract the AC3 audio and convert to WAV using BeSweet. Then use that as Audio Source in TMPGenc.

If your making DVDR's or SVCD's from the AVI then just leave it at 48khz, thats never a problem. But VCD's must have 44.1khz audio

Hey, thanks for the tip on using Virtualdub and then Besweet.

I am trying to take a Star Trek: TNG Episode that was encoded in Divx with AC-3 audio and convert it to SVCD to burn. I tried using Nero but wasn't sure how it was going to turn out. It was converting but I never let it finish thinking there might be something better out there to use (and it was taking forever). And also, I'm thinking it won't have audio when it converts it since the file is using the AC3 audio?

Anyway, I'm by no means an expert and making SVCD's and converting AVI's/MPG's but when I opened up Virtualdub, it gave me an option to output the AC3 audio directly to .WAV. Is there any problem with using it? I noticed when I played the .wav file there was some slight pops occasionally but I think these were there on the original file. If there isn't, I guess you can skip the step of using Besweet?

If you set Audio to Direct stream copy (the default, when you go to Save WAV, you not actually converting it to a WAV but its just demuxing out the audio and the file should be named audio.AC3 not audio.WAV. It still needs conversion to a true WAV file with BeSweet.

If you check out the Tutorila Section, and follow the AVI to SVCD guide, you dont have to worrry about anything, it does all the conversions for you automatically.

Ah cool, yes I finally figured that out last night. So is this another program you are referring to? (AVI to SVCD?) If so, I'll go check it out. I'll go look at the FAQ you mentioned.

Okay, I sucessfully converted everything last night and made a good SVCD of the original AVI (that had AC3 Audio in it).

Here are the steps I used - Could you please look at them and see if there is any way to do it quicker or more efficiently? :

1) Opened original AVI file in VirtualDub and saved the Audio out to wav (which was actually the AC3 version). I then renamed the file from .wav to .ac3.

2) Opened the wav file (named sound.ac3 now) in Besweet and converted it to 2-channel (Stereo) Audio (which made it go from 65 megs to 512 megs - interesting - non-compressed?).

3) Opened TMPGenc and told it to make a 'Film SVCD - 23fps' - chose the original AVI file as the 'Video source' and the converted (512mb) wav file (soundnew.wav) as the 'Audio source'. I then let all of this convert - which took 6 1/2 hours on my slow Pentium II-400mhz.

4) Once converted to a single SVCD-compliant MPG, I opened Nero and laid out a SVCD with this new MPG and then burned it. Is it necessary to burn on slower speeds (10x or 4x) to get a better quality SVCD? I burned it on 10x but only because I was burning onto CD-RW.

Also, my only other question is, in TMPGenc when encoding the new SVCD mpg, it asked about a 'Constant bitrate' for a 74-min CDR and I chose the 'Auto setting' which made it around 1920 or so. I then chose the 80-min CDR and clicked the 'Auto setting' and it increased the bitrate and also the filesize to the full size of the 80-min cd (780 megs or so? - the 74-min was around 720 megs I believe).

Realizing a 80-min is 700mb, there must be some overhead in this file - but my question is: Does the bitrate have a direct effect on the quality of the resulting mpg file? The only quality problem I noticed is maybe two times throughout the 45min feature where the actors arms looked like they were in 1/2 speed or slow motion. Other than this, nothing else quality-wise seemed noticable. Is possibly 23fps not enough? Do I need to go to 29fps? I believe 23fps is what the original AVI file showed when I checked it's fps.

Thanks,

Dabos

the bitrate is the quality more or less, if the source movie is good. HOw higher the bitrate how more data is used for the image and the better the quality would be.



i believe this is hardly used.
You should try PAL (25fps) or NTSC (23,97fps)

First of all there is no such thing as a Film 23.976fps SVCD, TMPGEnc will automatically run Pulldown after encoding to convert it to 29.97fps.

As for VCD's or SVCD's, an 80min CD will actually hold 800meg, not 700meg as printed on them, thats quoted for Mode 1 data.

If you followed this quide, all you need to do is load the AVI in, set it up (first time only) give an output folder and hit go. It does all the audio conversions automatically, allows inclusion of Chapters, opening pics, etc and you end up with a Cue/Bin file ready to burn or an MPEG file ready to burn. It also uses CCE to do the encoding and is substantially quicker than TMPGEnc.

I have used tmpenc for converting divx-films to DVD and when the movie containd mp3 tmpgenc makes no problem but when the audio is ac3 it convert without problem but the output has no sound. So i searched for a solution, and i found en litlle prog. called avi2mpg that can decompres your movie to a file with pcm sound. When using this output in Tmpgenc it works, i even used the same file for the video and audio input. So i don't extracted the audio. The prog i used is actualli called avi2vcd Version 1.3.10 but it contains a avi audio decompresser. I searced the net but didn"t find it. I found this last year. When someone wants it let me know.
I was frustrated when converting the same movie 4 times and found out 4 times that there was no sound, so if i could help....

TMPGenc cant handle AC3 audio, thats the problem. Then a again, all you want TMPGEnc to do is encode the video, then you manually extract the AC3 audio out of the divx and author them both in TMPGEnc DVD Author ready to burn to DVD. Why would you use "avi2vcd Version 1.3.10" if your coverting to DVD?
