Used Cucusoft to convert a 1hr 36min Xvid to SVCD.
Outputfilesizes:
Video - 625 MB m2v
Audio - 152 MB MPA
When using Tmpgenc Exp. to join audio and video, the audio went out of synch. Tried to use VideoReDo to fix it, but since i have a slow computer, 466mhz..(buhuhu), all processing power is used up, so when editing the video or audio there, it was not possible to hear if the audio was in synch..
Please, I'm pretty fresh at this, so all help will be appriciated!
When posting to forums before, asnwers has been few, so REPLY, pleeze..
I am an old C64 - 6502-coder who was caught phreaking in early 90's. Sold my equpment, and didn't have computers as a hobby before 2004. I saw the birth of filesharing, and I am really impressed how everything evolved.. Into video&audio.

If you have TMPGEnc, why use cucusoft?

I have the 5 in 1 package, but the outputsize of the file is like 1600MB! Why this enormous difference?
Cucusoft do use like 20 hrs to convert 700 MB Xvid into SVCD, but if the movie is under 1hr and 40mins, Cucusoft converts the file so it fits into ONE CD, while Nero and ceveral otherMPEG2-encoders gives you allways an output file whitch is much larger, in fact, twice the size!
If you read this, please tell me why...
I'm really a retro guy, and havent done this stuff for more than a couple of weeks, but I learn quick..
Please, reply...

Bitrate. Higher bitrate= bigger file.
Find a good TMPGEnc guide here: http://members.dodo.net.au/~jimmalenko/AVI2DVD.htm
It applies to dvd, but the same basic principles apply to (S)VCD too.
CCE, Mainconcept, or Canopus could do the same thing in about 3 hours. Even Nerovision express would take 4 or 5, but you'd get a nice menu with it, and Nero will split it over 2 or 3 disks.
A 700meg AVI doesn't say much. 1:36 long movie, if you want a decent quality video from that, it should probably span 2 disks at least, maybe even 3 for very high quality.
See if you can find a good guide for TMPGEnc AVI to SVCD. I know that SVCD2DVD (also does AVI to SVCD) can do it easily, using TMPGEnc to encode, and you can tell it to use 2 or 3 disks for best quality.

Thanx for reply.. Well, the TMPGEnc has some problems with the Xvid. I used a program(don't remember the name) to find what type of codec was used in the Xvid, but most of my Mpgeencoders say :unknown codec. When I look at MR-frog's SVCD-works(chickenshit.dk), he has managed to put films like Alien VS predator, Saw and the Grudge into one SVCD. I know the average bitrate for SVCD. (Highest-2420, lowest-1980, average-2390) but can you reduce it further? When the picture is black, and there is only audio in a part of the film, couldn't the lowest bitrate be as low as 224 kbps?(only audio?) The film was in a strange format (540*308, or something) and when it is in 4:3, there is large black areas over and under the picture. Does I need a bitrate as high as 2420?
Anyway, tell me what codecpack I should install for my 466 Mhz computer to get TMPGEnc to work properly.. I would be grateful...

Codec packs usually mess up more than they fix.
Get GSpot. Open each AVI you have, find out what codecs they need for audio and video, then download and install ONLY those.
Usually Divx, Xvid, 3vix, and maybe a couple more are all that's needed.
If you want multiple movies on one CDR, take a look at KVCD templates for TMPGEnc. Done right, you can probably get 4 hours per disk, at a reasonable quality (at least as good as SVCD in most cases).
Beware these may not play in your standalone, you'll have to test. Simply lowering bitrate to audio only during black sequences is nice in theory, but you still need some video bitrate to maintain the stream.
This is why VBR is used in 99% of cases. The bitrate will drop to minimum automatically, in scenes that don't require it.
Having black boxes is normal. If they aren't there, an odd aspect film will either appear stretched or squished.

OK, dude. I've downloaded the GSpot, and deleted all codecs I could uninstall. But when I ran GSpot, I was told ther was 174 codecs, or something! how do I get rip of those?
So I downloaded xvid codec and MPEG2 codec, and tested TMPGEnc. It was SLOOOOOW! So I tried out MainConcept, and it ran a lot faster.
I splitted the Xvid into four equal-sized files. That won't be a problem? I just did it b-coz converting takes all CPU-power, and I don't have time to wait forever to test out the convertion.
Can I join the converted MPEG2(SVCD)-files later, and will it stay in synch where I join it?
Thanx many times for replying....

Tmpgenc can be slow, but it depends on your settings.
Mainconcept is much faster at it's default settings.
If you want good output, you should have left the video together, and encode it as one movie, not 4 bits. Joining after can be done, but you could end up with all sorts of problems, audio sync, overlapped frames, whatever. It depends on how you want to author it. Cuttermaran will join your chunks, and it's free, but you'll have to Demux them first. There are other programs, but they cost.
If you're going to get impatient about encoding times, then you should get a much faster computer, or learn some patience. This hobby is NOT for hyperactive people. It takes time to do it right.
