SVCD to DVD problems

[zorinsmarket]

I've extracted 4 SVCD mpegs from 4 cues using ISObuster, I loaded them in Tmpgenc to join them together and was then gonna make a DVD out of them, but after the join I played back the vid, it plays fine for about the first 26mins, but then loses audio for awhile, then the audio comes back on, but is horribly out of sync, whats the deal with it. Is there a way to correct or fix the 4 SVCD files I have in order to put them on a DVD-R other then the route I'm going. Any expert know how on this would be greatly appreciated.

Peace,
Zorin

Is there an easier way to convert the 4 SVCD files I have to DVD other then the route I'm going. Any expert know how on this would be greatly appreciated

Wouldn't "Easier way to convert SVCD to DVD?" be a better title than "A little help needed".

The idea is to get the attention of someone who might know the answer.

How about telling me how to do that then, instead of writing an empty reply there genius.

Thanks for nothing,

Take your problem and write it out. Then say to yourself "What would be a good subject line?" It will probably contain some of the same words that are in your problem (but not so many).

If you need any more help on how to write a useful subject line just let me know.

Ulead movie factory 2 supposedly will let you do this. It will give you the choice of playing multiple film clips together as if they are 1 long clip. You can convert each svcd clip to the DVD format individually. Load them into Ulead movie factory 2.0 and choose a continuous play mode. The clips will then play without interruption as if they were one clip. There is a guide to doing this on this site. It is a guide to joining svcd clips, but it will work with DVD clips also. You can download a trial version of Ulead from the tools section on this site. Joining svcd clips are tricky and often result in sync problems. Good luck.

You will need to convert the audio from 44.1khz to 48 khz to make all happy. See this page for ideas:

Good luck - it can be done!

Thanks kitty and Laddydaddy, you have provide me with what I needed to know, plus I have the newest Ulead DVD MovieFactory too.

Thanks again

Well, I have had a TON of exp dealing with trying to join films, using ULEAD. And this is what I have got:

- First, ULEAD will alow you to continue your play with all 4 mpeg's There will be about a 3 seconds pause, not a biggy, right? Wrong, if I cam going to burn a movie on my DVD, I want it perfect. So, this option was not valid for me. I would not suggest it, although, it might work with your case.

- Second, I tried the same thing you tried, join all 4 films, NO GO, same problems, and this site did say it would be buggy. So, i read on, got better aoftware (demo, only let me do 29 seconds) and I dont want to buy that program, there has got to be another way.

- Third, I took all 4 films, slit them, sound, and video. I joined all video with tempgc, and that worked great. I did two at a time, so I would have 2 files now, and join the next 2. Well, the first two went pefrectly, i slit them, i joined them (sound to sound, vid to vid) and then joined the sound to the vid. Worked great! I was so happy. Then I went and tried to join the next two, and I cant open anything in tpemgc anymore. I cant even join em, I cant do anything. So, I think when i was slpitting and joining, and joining again, it got messed up with the way the movies are SUPPOSED to be layed out, although it played fine with DVD software, but not WM9. So, I am in the same boat, I need a way to make this work, if anyone has a clue, or maybe knows why my final plan did not pan out, please reply. This is importnat to me. I want this DVD!
Thanks to all who reply

I stayed up till midnight last night working on the Ulead project as per the guide and the vid cam out like junk, I using LORTT SVCD as my vid and followed the guide for SVCD to DVD-R, but when the vid started there was alot of pixelation the audio started in sync then about 22mins in to the vid the audio came out of sync, and also when the movie started half the movie was off the TV screen, what gives, I don't understand, there has to be a way to do this right.

Peace,

I suppose you are converting a version of a movie done in 4 SVCD's into a DVD version, right?

I have had the same problems and perhaps the reason is the same. You say audio get's out of sync (and video is pixelated) after 26 minutes. Is this where the first SVCD segment ends? (I suppose it is). If so, then the problem seems to be bad splitting made originally.

If the first segment doesn't have exactly the same length, (e.g. audio is shorter than video), then while first segment video has not yet finished, the second segment audio will jump in after joining.

Check that audio and video have exactly the same length. Video is best verified in frames. Load the MPG file into a program that tells you how many frames you have and divide this number by the framerate (e.g. 25 for PAL). Extract the audio into a WAV file and load it into VidtualDUB. It will give you an exact length for audio in File Information.

Another cause of the problem is that MPEG streams are not too good for splitting and joining. The reason is that too many frames are inter-related (talk about B and P frames) and unless you cut or join at GOP boundaries, you are bound to get into this kind of problems.

When creating SVCDs (or VCDs), strict adherence to the standards is neither enforced nor too important. I have made several fine SVCDs with all the frames forming a GOP (that is all frames are one after another without any GOP headers - nice splitting points). Such streams are a devil to correct afterwards.

What I would try to do (no success promised) is to re-convert the MPEG files into AVI (use VirtualDUB or FlaskMpeg or anything you like. Encode them using DivX (use CBR @ 10,000kbps - will give you a manageable file size and no quality loss) and make sure you select Index Frames every few frames (I would choose 5 frames for PAL). Leave sound uncompressed.

This will give you a highly editable file and you can use VirtualDUB to trim-out excess frames (if there are any). You can use VirtualDUB to join the segments together (open the first file and append the three next segments). Put down the lengths of each of the segment and use VirtualDUB to monitor playback at the join spots. You may have to fiddle a little bit with individual segments until you get it right.

While you do this, make sure virtualdub is "direct stream copying" both video and audio. You don't need to uncompress and recompress each time. This will make dubbing as fast as (almost) copying the files.

When everything is ok, write the joined segments into a new AVI file (again direct stream copy) and use Tmpgenc to encode into an MPEG-2 file.

Two words of caution:
DVD MPEG-2 must have audio sampled at 48kHz. Tmpgenc can do this (as can VirtualDUB). You will not get any audio sync problems doing this.
Also, GOP structure is important for DVD. Some DVD authoring programs (and some DVD players) will not play (at least correctly) MPEG-2 streams unless the GOP has a length of less than 18 frames. In Tmpgenc, in Settings, adjust GOP structure settings until you get a GOP structure of IBBPBBPBBPBBPBB or something like this (I prefer a GOP of 15 frames each).

There is a fine guide in VCDHelp.com on how to configure Tmpgenc for DVD compliant MPEG output.

Finally, the problem you are having is actually a conversion problem. A posting in the appropriate forum would spare you from unproductive comments.

Thanks for the help guild I'll will give it a go and let you know If I worked for me.
