Audio Sync

Did you know, recording in 16-bit audio is suggested not only for its improved quality, but also because it will save you the hassle of rendering a 12-bit audio project to DVD. I did not know this, but now I do. Knowing this before today may've saved me numerous DVD-Rs, but alas I did not know this then and so those discs are lost forever. Had I only the foresight to look into the differences between 12 and 16-bit audio, hours of burning time might not have been aflame in vain (aFIV)! A mere four bits of audio, transferred from medium to medium, so very important. It seems almost metaphoric...metaeuphoric, even.

The issue with non-16-bit audio files seems to be that they do not export keeping video and audio in sync. Depending on the length of the film, the audio jumps ahead of the video and slowly increases that lead up to a couple seconds. This means that on a standard length motion picture (1.5 - 2.0 hours), you can watch about half of the movie before this is too annoying to continue. This is however, not a problem when just putting a movie on for ambiance. The quality of the audio isn't noticably inferior (at least to my ears). When you look at the television though, the noise will not sync up with the video. This is important to understand.

The remedy hear (misspelled for pun) seems to be converting the audio to 16-bit prior to burning. This is what I will be looking into before attempting to render another 12-bit movie to DVD again. If you know how to do this already, you should leave it in the comments. You could be helpful. You could be full of help.
