Sound breaks up on burned DVD -AC-3 Encoder - MAGIX Community Forums Archive

Subject:Sound breaks up on burned DVD Posted by: shprena Date:1/8/2007 6:05:43 AM I created a photo slide show in the latest version of Vegas 7. I rendered the video files as MPEG-2 (DVD-NTSC) and audio as AC-3. When I brought everything into the DVD Architect, the preview played flawlessly. Then I prepared and burned the files on DVD (R-) and in some parts the sound does not play right (it interrupts for a second or two in a couple of places). I wasted many DVDs thinking that was just a bad DVD but the issue persists - in the same spot every time. I think the problem is with DVD Architect because, as I said, the MPEG and AC-3 files play flawlessly before I burn them on a DVD. Is this a common issue? Does anyone know how to fix it?
Subject:RE: Sound breaks up on burned DVD Reply by: ScottW Date:1/8/2007 7:25:22 AM It's not a common issue and I would be more likely to suspect an issue with your player possibly related to bitrate or a bitrate spike. One thing I've noticed that people have a tendency to do is use the highest bitrate possible thinking that this gets the best quality and while it may, the downside is that high bitrates create the most problems. If you encoded your video at 8,000kbps, lower it down to 6,000 - likewise, if your AC3 is at a high rate, lower it as well down to say 192. Quality media can also play an important role here. I get excellent results with Taiyo Yuden media and generally very low error rates. You might also try the Nero speed test tool and see what the error rate on your DVD is like. High error rates can result in problems like this as well. --Scott
