Problems Converting PAL SVCD to NTSC SVCD Audio Out Of Sync

[hiflyact]

Hello Everyone,

I am hoping someone can give me some insight as to how to fix this problem I am having. I have a video source it's in a PAL 25fps with 44100hz audio. It's a large file in 2 parts, not that it matters. Both parts play fine in Media player. I want to convert it to 29.97fps SVCD NTSC. Since my DVD player won't play SVCD I have to use the VCD header trick otherwise I get the green blocks all over the screen.

Since my DVD player only plays a certain kind of RW disc I only have 650MB per CD to work with, so I used AVI-MPEG-WMV Splitter software to cut the 2 part video into 4 sections so I would have 4 cds. All 4 of these parts play perfectly in Media Player.

Here's where it gets weird: I can't open the mpeg directly into TMPGEnc Plus, I get some error about it being unsupported. So I frameserve it using VirtualDub with mpeg 2 support. I set the video stream to direct stream cop and the audio to direct stream copy as well. I made sure that the frame rate box under the video section was set to no change. I frameserve it to TMPGEnc Plus as set that to SVCD NTSC 29.97fps.

The first part of the video (part 1 of 4) comes out perfect when I do the VCD header trick and play it my DVD player, everything is in sync. Part 2 of 4 using the same exact methods above comes out with the audio out of sync. Part 3 of 4 seems to be in sync with the video and I'm sure that 4 of 4 will be out of audio sync too.

Can anyone tell me why this is happening or how to fix it? I even tried frameserving the video as the whole part (part 1 of 2) as I have it without cutting it. Then when I add the VCD header trick and split it so I can burn it onto my RW disc, the same thing happens. I just can't get the whole thing to come out perfectly in sync. It's driving me nuts. If anyone can help me, I would appreciate it, thank you very much.

Here's where it gets weird: I can't open the mpeg directly into TMPGEnc Plus, I get some error about it being unsupported.

Try this:

If you get an error message when opening like file unsupported or can not open or is not supported
or you get an empty(black) video preview window
or the video look wierd in the video preview window like green or purple or pink
Try first to change the directshow codec reader priority settings in TMPGEnc under Option->Environmental settings->VFAPI plug-in and right click on the DirectShow Multimedia File Reader and increase the priority to 1 or 2 or to the top of plugin-list and try open the video.
If that does not help be sure that you have installed DivX or XviD or MPG2 or DV Codecs, read here how to identify what codecs you need.

What I meant by getting an error in TMPGEnc is when I try to open the PAL format video part that I have. When I'm frameserving it from Vdub to TMPGEnc, the preview window looks perfect, no errors or funky colors, etc.

Under the environment settings tab, I don't see an MPEG 2 codec listed. I installed a trial copy of PowerDVD but even then it didn't put the codec in there. If the codec wasn't there, then it wouldn't convert anything, right? I'm getting video files that are perfect and others are out of sync.

[Tommyknocker]

Have you separated the video from the audio, and then put them back together once you have encoded the video to the proper format?

[hiflyact]

No, I haven't done that. I didn't think I needed to. Would I need to use Vdub to that? I can't open the PAL format directly into TMPGEnc. I can however open it in the Mpeg tools section.

[Tommyknocker]

Yes, you can save audio as a wave file only. You can also load any MPEG file in Virtual Dun MPEG-2 mod.

[hiflyact]

Okay, I stripped the audio off and saved in wav format (uncompressed). What do I need to do now? Frameserve the video file to tmpgenc and then load the wav file for the audio source? I'm not an expert at this. I appreciate all your help so far. Is there a guide or link you could point me to on where to go from here? Thank you

[Tommyknocker]

Exactly. The link to the guide is the red tect that reads "save audio as a wave file" in my previous post, but you have the gist of it.

[hiflyact]

Okay, let me see if I got this right. I read your link, but it doesn't say anything about the video unless it's in avi format which it isn't. I got the wav file that will be my audio source in the SVCD NTSC template in tmpgenc. The video source in the template will be the vdr dummy file that I will be frameserving from vdub. Is that all I need? Anything I'm missing or boxes I need to check in tmpgenc regarding framerate, etc. Thank you sir

[Tommyknocker]

You are only changing your audio source for now. Make no new changes other than that for now.

[hiflyact]

Okay, so forget fserving the video into tmpgenc. I just open the wav file in a NTSC svcd template under audio and leave the video blank? and then encode the audio? I think you've lost me or I'm getting confused.

[hiflyact]

If it's any help, I finally got the MPEG2 codec to install so now that is in the environmental settings. I can now open mpeg2 files in tempgenc. Where do I go from here in converting this pal to ntsc? Thank you

[Tommyknocker]

Select Load. Select the NTCS DVD template. Select Start.

[hiflyact]

Unfortunately just loading the pal format svcd into tmpgenc and choosing the ntsc svcd and selecting start still leaves the audio out of sync. I even tried it with and withouth checking the "do not framerate convert" box. I got the same result, audio out of sync. Am I doing something wrong?

[Tommyknocker]

But have you laoded the separate audio source yet?

[hiflyact]

Yes, I loaded the audio source (the wav file from vdub that I stripped off). For the video source I loaded the mpg file. I am assuming that the wav file will override the audio that is with the video. Doing this, I still get out of sync problems. I checked and unchecked the do not framerate convert box, both ways I have problems still.
