Hello,

I have burned a DVD for my first documentary film. I used Premiere Pro to edit and Encore to Burn it.

A few people who have bought copies of my film told me that when they play back the DVD in their DVD players the audio level goes up and down drastically all by itself.

I played it on my DVD player at home and I am experiencing the same thing. What is odd is this is happening at different parts of the DVD every time I play it over. For example the first time the level would moving up and down drastically within the first 30 seconds of the DVD then when I played it again this morning it didn't happen until the last 5 min of the DVD which is a total of a 30 min video.

I then played it in my PC and Mac players and the level is fine. I also played the quicktime file and that has no audio issues.

I also analyzed the waveform audio and there is no major peaks or anything.

SO I came to the conclusion it does this in DVD players that have the Auto Dynamic Range option. Sometimes called Auto Gain. If Turn that off the level is fine.

But what's really weird is that I can play a feature film like Harry Potter on the same DVD player that has Auto Dynamic Range on and the volume doesn't change drastically.

So why is it that I have to shut the Auto Dynamic Range off on my DVD player for my DVD but not others?
 
There are 2 distinct items:

1. Natural dynamic range of the material, like classical music, or those special effect producers love to turn up. Here, there is nothing you can do except if your player has a Dynamic Reduction button or Night Mode Listening. Some audio encoder (paragraph#2) may have a dynamic reduction button u can use.

2. This is most likely what's happening to you. The different chapters you have put together have different audio levels, what you should do is, during ENCODING, tell the audio encoder to NORMALIZE, say to 90% of max. This way all the chapters' audio will be adjusted to give you a standard audio level across board.

There is only one Chapter on my DVD. It's 1 chapter for the whole documentary. As I pointed out in my Original Post the audio level changes only happen on my Sony DVD Player that is hitched up to my Surround System. If I play the exact same DVD in my PC it doesn't have these audio changes. Plus I have a friend who played the exact same DVD I let her borrow and there is no audio level changes either. It's only happening on my Sony DVD player in my living room and a few others I have but not every DVD player does this. I even have the Premiere Pro Project I used to encode the DVD and there is no audio changes there either it's all normalized and the level sits around -6db throughout the film
