help with frame rate issue :(

[warlock110]

i captured some TV using my TV tuner default program with the MJPG codec, everything is fine except that the frame rate is 29.967 instead of 29.970. and alot of problem starts from there.
Using TMPGenc i was able to encode the original 29.967 into SVCD, but it is extremely slow, so i decided to switch to DVD2SVCD with CCE.
well it didn't go too well as the final product didn't have any sound, they was unable to make any sound track with the abnormal frame rate.
So i was being a smart a$$, i went to virtual dub and under frame rate, i changed it to 29.970. The AVI that virtual dub produce was exelent, I didn't notice any sound sync at all, and DVD2SVCD took it in without any problem, but for some strange reason, the audio track that they extracted is way short, only around 10 min, and the movie is completely silence after 10 min. Now i'm stuck, any ideas to help a newb out?

Well, assuming that your capture is an AVI with the video and audio in one file, I would use AviSynth. If you've never used AviSynth, simply download and install it, then open Notepad and type this:

AVISource("the_name_of_your_file.avi")
AssumeFPS(23.976,true)

Of course, change the_name_of_your_file to whatever the actual name of your file is. Save this text file in the same directory where your AVI file resides (or otherwise specify the full path to it in the AVISource line). When you save this text file, name it whatever you like, but make sure you save it with an ".avs" extension. To do so, you will need to make a change in the drop-down box at the bottom of the "Save As" dialogue. Change it from "Text Documents (*.txt)" to "All Files." Otherwise, Windows will give the file a ".txt" extension and it won't work.

Now, open VirtualDub and load the text file you saved (not your video). You can drag and drop it if you like. You'll now see your video at 23.976 fps with the audio kept in sync. Just make sure "Direct Stream Copy" is selected under both Audio and Video in VDub, and select "Save as AVI" from the File menu.

That's it!

Of course, you can do a million more things with your AVISynth script, but that ought to serve your immediate purpose.
