Audio Delay in Menus

videomaniac wrote on 9/27/2005, 4:43 PM

Using SA 2.0, I have a .wav file as background media. When Previewing there is no delay when the menu comes up, the music begins immediately. After burning, there is a 3 second delay ONLY in the menu pages before the background media plays. Everything else on the project is fine. The .wav files do not need recompression according the the Optimize DVD panel.

Thanks in advance.

you testing it on a set top DVD player? Some players have a delay no matter what.

Sony DVD player. Does that mean everyone who plays this on a home DVD player will experience the delay? That does not sound reasonable for a high-end authoring program. Or...maybe SA isn't high-end...

The studio versions of the product are not high end, they are basically stripped down versions of the Pro level. Still, there shouldn't be a delay between the audio and video on a menu, assuming that you did everything correctly.

One thing that's important is to make sure that your audio and video clips are the same length. Also make sure you are running with the latest updates for the relase you are at.

Have you only tested on a single player? What happens when you playback on your computer or a different player?

is the audio 5.1? I've always seen audio start delayed in 5.1 on any player. It's normally something to do with the durround sound system.

>>...audio start delayed in 5.1 on any player...

I remember reading some white paper documentation on AC3 audio, and the long and short of it is to be sure to leave a small (nothing. silence) buffer at the beginning and end of the audio track. Without this, you stand a good chance of either a delay in starting menu audio or II have also seem the last .5 (one-half second) seconds chopped off. Then, you can take thaty same DVD to a different player and it can behave slightly differently...and this was all without DVD-A. It was with another DVD authoring package; not a cheap one.

I leave anywhere from 15 to 23 frames of silence at the head and tail of my audio and have never had to worry about it again.
