View Full Version : 42min video becomes 51 mins; NTSC > PAL?; don't need to 'burn'

Sorry in advance, but I can't find the answer to my problem of 'stretched files' using DVD2SVCD. (Searched with keywords 'stretched', 'files too long', etc.)

Started ripping a month or so ago and have had some success at the beginning, but since then, I've been trying and reading and failing.

I'm ripping Japanese NTSC DVD's -- they are 42 minute documentaries, in Japanese (only) with Japanese (only) subtitles.

Since then the final video file has become 50 odd minutes long, the sound/speech being dragged out and bass -- woman now sounds like man. It's happening at some intermediate stage before TMPGenc, 'cos when you play them (the audio and vid, too I think), they're too long.

Successfully converted two such that I could put them on CD's to give to students to play on their computers (as mpg files I guess). I.e. I'm not 'burning' them to play on stand-alones (maybe I'll try that later if I could just get the basics working again, consistently).
Using the orange smiley software DVD2SVCD. I think the trouble may have started when the free TMPGenc software started saying 'time up'. (I'll buy it if -- I'll buy anything -- if I know it'll work.) Meantime I downloaded it for another trial just until I can get the whole damn thing working.

--------------
Q1. Is there a list of files that one should end up with in the folder that I could see somewhere? A screenshot would be great.
--------------

I'm sure that once upon a time in TMPGenc there was a separate audio source file and video source file, whereas now there's just a video source, and also I notice that the Stream Type is "ES (Video only)" instead of what I think it used to be, namely "System (Video+Audio)"

-------------
Q2. Since I'm only wanting to play these on computer (at the moment), maybe I should stop selecting NTSC to PAL. Do you think?
--------------

I should say that instead of wasting 8hrs each time I try to do it again, I've been using Japanese NTSC karaoke DVD's and just doing one song to see if that works, and again, a 4 min song is stretched to 5mins, and the woman sounds like a man.

-------------
Q3. Any magicians out there?

Thank you very much for your patience.

Johnfused:

Try a search with "corruputed audio", or of something of that nature. When all else fails, read the guides and FAQ's. The information you need is in there somewhere. You may have answered one of your own questions if the curruption and TMPEG's messsage arrived simultaneously.

Good luck......ammck55

Thank you ammck55

I've had a go now at searching corrupted audio, but that route has not brought me out into sunny pastures shall we say.

In fact it's not just the audio. One of the mpv files I've just viewed is 51 minutes long (according to WMP). It should only be 42 minutes. Is there any way I can crush it down to the correct length?

I have indeed read the guides and FAQ's -- and not 'when all else fails'. Oh, well, must go to bed it's 1:15 a.m. "I sink, therefore 1 a.m."

With the video everything is clear (for me:D ). You have NTSC source with 29.976 fps (and the video is more than 42:30) which has about 76500 frames. Every frame is encoded and the speed is slowed down to 25 fps (PAL). Then 76500/25/60 = 51 min. Why the audio is not converted I don't know. You can try to encode the movie directly in TMPG, selecting PAL template and System(Video+Audio). I see you are using DVD2SVCD. Then it is better to post the problem to DVD2SVCD BASIC TOPICS forum and don't forget to post there the log file DVD2SVCD produce.

Greetings,

I'm glad the extra info about video lit your bulb!
You've certainly inspired me to have yet another go in a few minutes, once I've bulldozed a coupla gig free.
Since it appears to be a framerate thing, which are you suggesting has cocked up:
1. me (think a Tom Jones hit) making the wrong settings.
2. the DVD2SVCD software bundle
3. the registry
4. Windows
5. the Russians

Can I ask you a coupla repeats:
1. I can't find a list (screenshot would be best) of the files produced at the end of the whole process, so I can EASILY make a comparison with my attempts (yes, I should have done this myself at the start but life was so much easier then, it's harder than that now).
2. Is buying TMPGenc gonna make any difference? ('Cos on the one hand I don't care what I spend as long as it works, and on the other I've had enough of buying willy-nilly huge drawerfuls of software and pretty boxes that's junk. In fact I'll buy a whole bloody computer just to do this stuff if I knew I wouldn't be spending my life fixing the damn thing.)
3. since I only want to play the files on computer, there's no point me converting from NTSC, right, so I'll have a bash at NOT converting to see if it makes any differencio.

Blessings on you sport. I shall have another bash.

Hi-

If I'm not mistaken, the NTSC to PAL setting for DVD2SVCD assumes a 23.976fps NTSC source. That is, it assumes you have a film source which you have either Force Filmed with DVD2AVI or IVTC'd in the .avs.

If your source is true interlace material, then it won't work. DVD2SVCD uses the AssumeFPS(25) command and takes the same number of frames and (in your case), slows them down to 25fps (as Abond said), and turns the woman's voice into a man sounding voice as a side effect. If you are able to bring the frame rate down to 23.976, then when converting to PAL at 25fps, it actually speeds it up by about 4%. In that case, the slightly higher pitch of the woman's voice may or may not be noticeable.

So, the question becomes, what kind of source do you actually have? If it is true NTSC interlaced material, then I'd say keep it at 29.97fps and deinterlace it, since it's going to be played on a computer. But if it is a film source, I'd say Force Film or IVTC it (which will result in much better quality for the same file size), and convert to PAL or not, up to you.

Did any of that make any sense?:)
