Hi everyone. I'm a refugee from the Sony forums, with very little activity since early 2012. Until upgrading to Vegas 19 recently, my last version was VP-12 and my last update to DVDA was 6. These, of course, go back to before the acquisition by Magix and the continuation of Vegas Pro along with the abandonment of DVDA.
As it would happen, I've been tasked with creating a followup to a DVD project that I created in late 2011. I still have a functional DVDA-6, and have been creating test burns as I refresh my memory on the techniques used last time around, particularly for the scene selection menus and a somewhat complicated playlist that threaded segments of two separate programs together as if there were a single long video that repeatedly intercut between the two. I've been successful in duplicating that for this follow-up, but there's a new feature to be included in this one: a commentary track.
I've looked at the manual, some forum posts and Youtube videos that reference alternate audio tracks and it seems easy enough to do, but I'm having a problem. I am trying to use a single video file that is to have a standard dialog track and a commentary track. I was using the same technique that was successful in my playlist example -- importing the mpeg file multiple times into the root of the project, which allows it to be referenced in different ways in the project, yet only being written to the disk one time. Very cool! But it's not working that way when I try to assign a different audio (ac3) to replace the dialog track with a commentary track.
Let me explain with some sample numbers. Let's say that I have an mpg2 that's a little under1GB in size and the dialog AC3 file is about 40MB. (keeping my test files smallish so that I can burn to a 4.7GB DVD-RW) There's a little overhead for a very basic menu, so DVDA reports a project size of approximately 1.1GB. Here's the rub: if I go to one iteration of the mpg2 file in the root and change the replace the dialog AC3 with the commentary AC3, which is also about 40MB, the project size immediately almost doubles to 2.1GB. This makes it look like it's no longer writing only one copy of the mpg2 file to disc, it looks like the AC3 is somehow 'bound' to a separate iteration of the mpg2 and is going to take up much more than just the 40MB size of the replacement AC3 file.
Isn't it possible to add a commentary track without doubling the size of the video file that it's supposed to be played with? This seems like a huge disk-space penalty to pay for wanting an alternate audio track.
I realize that there aren't many people doing DVDs, but sure hope someone is able to give me some ideas how to resolve this!
Thanks for any comments & suggestions...
