SVCD to a burnable DVD mpeg-2

[dqtus]

Ok I have like a bunch of SVCDs and I want convert them into DVD-video. I have 2 ways to convert SVCD to DVD mpeg-2. The first way i like to do is use isobuster to rip the mpeg-2 file from the svcd and then load it into the tmpgenc wizard and convert. However, recently I have been getting a lot of crashes in the program. I use XP so it gives me that had to close thing or whatever. It either occurs in the beginning like 2-3 seconds into the encode or at some point in the video or occurs and the encode keeps going and finishes.

If this happens and the video doesnt finish encoding I would resort to loading the mpeg-2 file into dvd2avi and then come out with a d2v and a mpa file. I load those into tmpgenc and encode it and sometimes it will work. At other times it says d2v cannot be loaded or not supported. Basically I want something uniform. I don't want to put my system through all these trial and errors and there isn't any guide that seems to work just right. Does anyone have any suggestions or can give me a guide that will always work. Thanks

Try SVCD2DVD it works great.

You may not need to reencode the SVCD video since it is already in mpeg-2 format. You simply demux the mp2 audio stream, convert it from 44100 to 48000, and remux the altered audio stream with the original video stream. This will give you a MPEG-2 file with a DVD compliant audio stream. Even though the 480x480 resolution of the video stream is not a standard DVD resolution, I think most modern DVD players can handle it. This method has worked well for me, and it requires very little effort and time.

If your player does give you problems, you can always use DVD-Patcher to modify the MPEG-2 header so that the player thinks it is actually at 720x480 resolution.

Hope this helps,

ohhhh ok!

Wow this seems so much easier. I'm going to try it now then. I know how to demux in tmpegenc and I believe there should be a tab for remux as well in the mpeg tools right?

Ok I just remuxed the video with the new audio and tried to load it into tmpgenc dvd author but I got this error

*The video GOP is too long.

Hmmm what should I do?

Also the file is only like 443mb while another mpeg-2 SVCD video that I encoded into mpeg-2 DVD video is 1.4gb. This sort of concerns me because of the difference in file size. Will I experience a great quality loss?

Exactly. I should point out that certain DVD authoring programs, such as DVD Workshop, will try to convert the 480x480 video stream to 720x480, or may reject the video completely. If you have one of these programs, patching the MPEG-2 header to 720x480 using DVD-Patcher will usually remove the authoring program's desire to convert the video.

Good luck!

ah ok,

so dvd patcher changes my file or does it output a new file? Also should I patch the whole file or just first header. I'm using it now, but it's my 1st time with it. Also I'm assuming the options for bitrate like 3.5, 8, and 15 would increase the file size and make it equivalent or so to the other dvd mpeg-2 file I encoded with tmpgenc right

If everthing works right when remuxing the video stream and updated audio stream, the final file size will be the same as the size of the original file. The error message you are listing leads me to believe there is a problem with the original video file (bad frames ???). Unfortunately, my knowledge is rather limited, and I'm not exactly sure how you would go about tracking down and fixing the problem.

Hopefully someone else will be able to provide some guidance.

ok yea I got it to work

So since it's the same file size then I could fit heca SVCDs into 1 DVD then right? But then there will probably be a quality loss too if that's the case huh? Or will the quality just be like my SVCDs except a lot of them on 1 DVD

Glad you got it to work. Since you didn't actually reencode the video, there should be no quality loss from the original SVCD quality. From what I understand, if you had reencoded the video like you were initially trying to do, you would have automatically experienced some quality loss (unless you are applying filters to remove graininess, sharpen colour, etc.). Whether or not that quality loss would be noticeable, is another question.

Part of the reason I like this method is due to the fact that you can fit quite a few SVCDs on one DVD without losing any of the quality of the original videos (plus its really quick when compared to the time required to reencode the video). Provided that the quality of the original SVCD video is good to start out with, the quality of the video when played back from the DVD will be just as good. I have been very happy with the results. However, if your DVD player will allow, I recommend that you do a test burn with a rewriteable disk to ensure that you are also happy with the quality.

cool im burning one on a dvd-rw now

And just 1 last question, since i loaded it fine in tmpgenc dvd author and I created vob files etc and am burning it as a dvd-video, this is a playable dvd on just about any dvd player right and not just a svcd-dvd because i heard svcd-dvd doesnt play in all players.

Crap...I had to look up SVCD-DVD in the glossary, as I have never actually heard the term before. Turns out that the disk you end up with after following the procedure I gave you is indeed an SVCD-DVD. The reason why it is not considered a true DVD is because of the 480x480 resolution. And, as you already know, not all players can play SVCD-DVDs. The three players I have tried my SVCD-DVDs in have all worked flawlessly, so I had no reason to question my methods. From what I could gather in the forums on this site and at Doom-9, patching the header to 720x480 with DVD-Patcher often clears up incompatibility issues.

Sorry if I lead you down the wrong path. Hopefully the disk will work in your machine, and it will not have been a waste of time.

ah ok, so the dvd patcher should make it a normal dvd then? I actually have a machine that doesnt play svcds whatsoever and I tried the dvd I made on it and it showed video!

However there are some problems though. I think this is with dvd patcher. I didnt preview the patched video and now that I did it seems to come out weird. My DVD is set to 352x480 (NTSC) resolution and my original SVCD was set to 480x576 (pal). So when I did the conversion it seems like the video got zoomed in and the video/audio are out of sync. When I change it to NTSC 720x480 it basically sort of zooms out and I see like this green box to the left of the video to fill in the empty video. Very weird. Maybe I should try svcd2dvd then? Is there a guide for that program? Unless you know of a way to fix this problem with dvdpatcher.

The remux video is fine though except it's sort of a square due to the resolution of an SVCD.
