dvd burning problems Susan 6/11/2007 3:07:02 AM when i get the dvd to burn (at times that doesn't work either) to play on a reg. dvd player the sound with get out of sync with the pictures and it seem to get worst as the movie plays. I have tried using other durning programs (I have Vista) but half will not work or they do the same thing.

The problem you're describing is fairly common even in professional grade authoring software. It may start playing in sync, then the audio gets a frame or two ahead of the video and if a long enough video near the end can be a second or more out of sync. This is sometimes called progressively deteriorating sync. What is the source audio's file type and bitrate? For home brew creation of DVDs the ideal bitrate for audio is 48,000Hz in AC-3 stereo or 5-1 format. Whatever DVD burning software you're using it should set to this common default. Playback problems can happen if the audio stream is compressed at a different rate or whatever application you're using does a poor job of transcoding making the audio file compliant. Some DVD players are what can be at fault too. They literally decode the audio stream slightly ahead of the video and the player gets stuck playing a game of catch up it can't win thus the problem gets more noticeable the longer the video plays. Some DVD players have a option to skip frames if it detects it is getting out of sync. Usually this is not as annoying as audio obviously being out of sync and is mostly transparent. You may be able to help overcome this by reducing the bitrate that your encode the video stream at. I know a lot of professionals that make the amateurish mistake of thinking more is better and end up using the maximum bitrate possible without actually getting any gain in video quality. All that does is waste space on the DVD and sets up DVD players to stumble, this time by skipping, stalling, causing audio pops, and some sync problems. If you can change the video bitrate try dropping down to 6,000 Mbps. If your DVD burning software supports it try experimeting between different constant bitrates and a variable bitrate. You only need a higher bitrate during fast action scenes. Other times the DVD player is loafing along and video can be encoded much lower during more dull moments and can drop to as low as 4,000 Mbps, sometimes way less. This is all taken care of behind the scenes, you simply have to set it, and forget it, assuming that option is available to set parameters. Since most home video is of less than stellar quality to begin with and shot with consumer grade cameras you're not really giving up anything in using a lower biterate, in fact you can improve performance of playback by dropping back the encoding bitrate.

RE: dvd burning problems Sendmealist 6/11/2007 3:01:06 PM - Suggest lower your "Burn to Dvd" speed to minimum and make sure your harddrive is completely defaged and chkdsk'ed before burning as best burns are co-lated with contiguous hard drive space, even with ntfs.
