25fps PAL to SVCD??

[illini19]

Thanks ADAM!!!!

I think that just about covers it. I'll be trying all methods above and post results later.

Appreciate the comments!

Adam,

I see what you meant about my way of converting from PAL to NTSC. The movie does speed up just a split of a second once in a while that's only noticeable during slow scenes, hardly noticeable during action scenes. But video and audio are insync, which is good.

I tried your correct way to get 23.976fps (w/ 3:2 pulldown) .m2v for video file, then save the wav and use BeSweet to convert from 25 to 23.976. But when I multiplex them together the audio is faster than the video. For mpg-2 there are only 2 options under multiplex: program and SVCD, no DVD, since I'm making it into DVD which one should I select? I used program to multiplex is that causing the video and audio out of sync? Do I need to run pulldown with audio as well? How to do that?

I also tried doing both video and audio at 29.976fps then multiplex, still the audio is faster than the video. What did I do wrong?

[adam]

You would use mpeg2 program stream, but honestly I wouldn't use TMPGenc for multiplexing at all. If anything, I would try bbmpeg. For DVD I always import the video and audio separately and let the authoring program do the multiplexing, but different authoring programs accept different things, and some do require a program stream.

No, you don't run pulldown on the audio. It should sync up on its own.

There have been alot of these PAL->NTSC conversion threads popping up lately and my advice in all of them has seemed to lead to sync problems, and I don't know why. Like I said, it has always worked for me, and that is how real PAL-NTSC conversions are done, but maybe its best if people just cut their losses. If the slight skipping isn't much of an issue, than I suppose just stick with what works.

[grimlock_007]

twen, i had the exact same problem, encoding went fine until i multiplexed them together then the audio was faster than the video,...by about 15-20 minutes. If you figure it out, let me know, cause i did it according to what adam had posted, and it still won't work.

[illini19]

ADAM your method worked like a champ!!!!

Not to post an entire guide but a short synopsis of what I did is:

FOR MULTIPLE SVCD's PAL (480x576) to NTSC DVD

-Took .cue/.bin to make MPG's
-Used TMPG to join clips together to make one MPG
-Loaded in DVD2AVI and "save project as" (couldn't load mpg in TMPG for some reason)
-Loaded .dv2 into TMPG and unlocked
-Encoded as video only at 352x480, pulldown, 23.976 fps, do not frame rate conversion checked
-Took WAV file and loaded into BeSweet and converted from PAL to NTSC and to .mp2
-Loaded .m2v and .mp2 into Maestro and authored DVD.

Like I said it worked perfectly.

I might write a more detailed guide but I thought I would let you all double check to make sure everything is OK.

Thanks again ADAM and ALL for input.

I'm glad it worked illini19, and your results kinda confirm my suspicion that all of these sync problems people are having are more result of the source rather than the methods used. Things like xvid and divx are just trickier to maintain sync when converting to mpeg1/2 in general, and especially when doing framerate conversions. The wide variety of audio formats that these formats use also complicates things.

[illini19]

Adam, it took me a bit to get the audio right in BeSweet. Just had to make sure all the settings were correct. Once I got that though, BeSweet and Maestro had no problems. The audio and video times were correct and in sync.

No problems after that.

Your right though, it all depends on the source.

OK, time now to play with something else and learn a new conversion.

[wmosner]

Adam,

Also tried your method and it worked perfectly to convert PAL SVCD to NTSC DVD. I had to run it thru DVD2AVI first because TMPGEnc would not accept the mpg from the BIN file. After that I followed your directions and everything ended up in sync.

Thanks, Bill

[illini19]

wmosner, I had the same problem with TMPG not accepting the MPG from the bin/cue from SVCD so I ran it through DVD2AVI (thanks twen) and loaded the d2v file in TMPG fine.

I wonder why TMPG has problems with loading MPG's from bins/cue files. Someone suggested loaded the MPEG2 file for TMPG, which I did but it would still not load.

No biggie, method still worked fine using DVD2AVI.

I wonder why TMPG has problems with loading MPG's from bins/cue files.

I believe the AVSEQ01.MPG file found in a BIN/CUE SVCD contains a RIFF header which TMPG does not like. I use VCDEASY v1.1.5 http://www.vcdeasy.org/ to convert to a "true" MPG file. In VCDEASY go to the TOOLS, MPEG TOOLS and do the Cdxa2mpeg conversion.

Another very good tool is the AVICODEC. The name doesn't do the program justice as you think it is only for AVI codecs. From the web site:

"Gives multiple information on multiple movies, particularly the video & audio codecs, if they are supported by the system (usign VFW or Directshow), and where to download them if not installed.

Movie types recognized : AVI, ASF & WMV, Real (.rm, .rmvb), Ogg (.ogg, .ogm), Mpeg-(S)VCD-DVD (.mpg, .vob)"

I should point out that the problem your having with the audio could be due to BeSweet. i've noticed that if you first convert the input to WAV, and then perform the frame rate conversion, and then convert back to MP2/AC3, you get better results. The one click MP2 to MP2/AC3, with the change in framerate seems to produce unreliable results. Take it one step at a time, converting it to WAV if it's not already, convert the framerate, and then convert to your final output format.

If your audio is only slightly out of sync at the end of the movie (say by a few seconds), then your problem is due to corruption in the source file. If it's off by minutes, then your framerate converted file is probably to blame. Make sure your multiplexing the converted file, and not the original audio.

I always convert to WAV from the MPG from the SVCD. The MP2 always ends up all screwy if I go with MP2-->MP2. I either use Vdub or TMPG to extract the WAV and then in BeSweet check PAL-->NTSC conversion and covert to MP2 or AC3. Works everytime.

I use VCDEASY v1.1.5 http://www.vcdeasy.org/ to convert to a "true" MPG file. In VCDEASY go to the TOOLS, MPEG TOOLS and do the Cdxa2mpeg conversion.

Interesting, I have always used VCDgear and did the bin/cue-->mpeg conversion. That MPG never loads in TMPG. That is why I used DVD2AVI and get the dv2 and mpa file. But I will try VCDeasy and see what happens next time. Just hope it will load in TMPG.

Thanks for the suggestion.

Even this can cause problems. Convert your WAV to NTSC/PAL (set WAV as your output type, not MP2/AC3). The output WAV can then be converted to MP2/AC3 in a seperate step.

You never answered. How far out of sync is your audio at the end? A few seconds, or a few minutes? Does it's length in minutes match your video stream?

[illini19]

You may have misunderstood my last post. I output the WAV from the original source and then convert in BeSweet with the conversion method I listed above. I always go from the WAV ---> MP2/AC3. Sorry to have mislead you.

How far out of sync is your audio at the end? A few seconds, or a few minutes? Does it's length in minutes match your video stream?

Audio is in Sync evertime. I have done say 10 of these conversions and it matches up everytime when I insert in Maestro.

Hope that helps.

[DJRumpy]

I have no idea where I got the impression you were having sync issues.

Please disregard...

[radiojef]

Illini19, i did exaclty what you said to do on your post from May 23, 200 14:51 and the video is fine, but the audio comes out screwy. I used besweet and followed your instructions but the mp2 has a few seconds worth of good sound and then it goes silent for the rest of the film. Have you ever experienced this problem before?

Is there another Audio encoder you wold suggest using?
Anyone?

[illini19]

radiojef, make sure you have all the settings correct in Besweet. If one of the options say MONO then the audio well in fact sound like hell.

I had the same problems a couple of times until I checked all settings and made sure they all had the desired output I was looking for.

Also, you can try doing the WAV---AC3 if you want. File size is not that much bigger. I have had excellent results using that function as well.

Also, look at my post from May 27, 2003 at 22:37. That is what I have done more than once and works every time.

Let me know how it turns out or if I can help in any way.

FOR MULTIPLE SVCD's PAL (480x576) to NTSC DVD

-Took .cue/.bin to make MPG's

Illini19, do you mean that you started with Actual PAL SVCD's and you took the .bin files from them and encoded them into Mpgs? What program did you use to encode the .bin/.cue into Mpgs?

[illini19]

Yes, I started with actual PAL SVCD's.

You can use, VCDGear but I prefer ISOBuster. Both do a good job, I just prefer ISObuster. Both programs can be found on this site. They will convert the bin/cue into MPG or you could just pull the SVCD MPG (AVSEQ01.MPG) out and copy to your disk when using ISObuster.

[DJRumpy]

Make sure that if you use VCDGear, that you turn off the 'Split MPEG' option, otherwise you'll end up with 50 odd tiny mpegs

[grimlock_007]

OK, I've still been having problems converting pal to ntsc, this time with another source. So I know that the source can't be the problem, it has to be the way I'm converting. I start up TMPGenc, load the SVCD NTSCFilm Template, load the .avi file, correct the aspect ratio and click do not frame rate convert, unlock the template and do video only, so it just encodes the video down to 23.976. I do the same thing to the audio by extracting the audio to a wav file and converting it to mp2 and slowing down the frame rate to 23.976. When all thats done I multiplex them to gether and the video is 15 minutes to 30 minutes extra than the original source file, but the audio is the same. Say I have a movie that is 1hr 30 mins. long, After the encoding is done the movie is 2 hrs. long.

I find it hard to believe that nobody knows why TMPGenc is adding like half an hour to the file, cause I know it isn't supposed to slow it down that much, according to adam the file should increase by 4%, which is about 4-5 minutes, not half an hour. Am I to believe that nobody else has had this problem?? Somebody has to know what I'm doing wrong. If anyone has any ideas at all, please please please help!!!

[DJRumpy]

Go back to basics. Verify your source file's framerate.

This thread is getting too long. What type of file is your source (mpeg/avi). You could do the whole thing with three lines in AVISynth:

AVISource("c:\folder\youfile.avi")
BilinearResize(480,480)
AssumeFPS(23.976,True)

Of course you may need to tweak the Resize command if your letterboxing needs to be changed. This file can be dropped into whatever encoder you like to use like TMPGenc. The output will be NTSC, and the audio will already be sync'd. Don't use any of the TMPGenc framerate options if you do it this way.

[grimlock_007]

Well I finally got it working anyway using TMPGenc just encoding it as NTSCFilm and doing the inverse telecine. Works perfect. It may not be the way everyone else does it, but i figure if it works, go with it. And yeah, this thread is too long.
