Another sound problem

I have just started using UVS 11. I made a movie using 5 clips. all went well until i put in on dvd, played it back and each clip had sound for the the first few mins then mute. i played with the program all night trying to figure out why. when i play the clips on Clips i have sound, when i play on Project and put on Audio View, the audio wave just stops, yet the clip has sound, there is nothing wrong with the clip. can someone help, its driving me made. ive set everything up to match the properties of the clip.

Is the sound the original sound that came with the video?

these are the file properties
avi
audio
bit rate 64
sample size 8bit
format ccitt u-law

i tried converting the file to something else and it worked. so if i have to convert it, why is that? now i have to try and convert it and keep the same video quality.

So these are MPEG-4 clips? That is a format that was developed for distribution and viewing, not editing. A lot of people have trouble with MPEG-4s. If you've found a work-around you may have to live with it.

For a video DVD, the only format you can use (no choice -- it is the international standard) is mpeg-2. So you have to convert your mpeg-4s to individual mpeg-2s. You can try doing this with VS -- I do it fairly regularly for video from a small mpeg-4 camera I have, and it always works, but others have reported problems. In that case, you can use another program, a freeware one called SUPER.

Make sure whether in VS or SUPER or whatever other program you use, that you convert to DVD-compatible mpeg-2, as you can have mpeg-2 whose properties don't meet the international DVD standards. In VS you choose Share > Create Video File > DVD and this will give you the right properties. Use LPCM or Dolby audio. Mpeg layer 2 audio is in the PAL DVD standard but not the NTSC one (though is usually works in NTSC players these days).

Then play back each of your new mpeg-2 files in a third party software player like PowerDVD or WinDVD or even Windows Media Player, to make sure you have audio all the way.

If you do, you can then burn the mpeg-2s to DVD: Share > Create Disc > DVD. Make sure you go to the middle of the three icons in the bottom left of the burning screen, and tick the box beside "Do not convert compliant mpeg files".

well it worked with the files converted to MPEG-4 but the audio on the second clip in the project went out of sync. so near yet you know what.
