DVD Studio Pro: April 2009 Archives

When is it sufficient to use the Dual Layer Breakpoint in DVD Studio Pro?  First let's refresh what a Dual Layer Breakpoint is.  We know that normal DVDs hold 4.7 GB of storage or approximately a 2 hour movie.  But what if you have 3-4 hours of movie time to burn on a disk?  Do you choose to burn 2 regular DVDs or do you choose to switch to a Dual Layer DVD?  Comparative in cost, Dual Layer Disks have really come down in price and aren't much more than normal disks.  So it's really a matter of preference of how you want to deliver your product.  You can put 3-4 hours of movie time on a 4.7 GB disk if you encode it at a lower bit rate, but it gives you a much lower quality output.

So let's assume we're burning dual layer disks.  If you don't set a breakpoint in DVD Studio Pro, the application will set the breakpoint automatically.  Sometimes it will break at an inopportune point in the movie, say for example, during a huge action scene like a car chase, the breakpoint will leave a "hiccup" in the video.  So this is why we want to set a dual layer breakpoint.

Breakpoints need to be placed so that the first layer is mostly filled.  You also will want to find a place in your movie where a breakpoint will not be noticed.   Often a chapter marker makes a good breaking point such as, where you might have a "fade to black".

There are 2 ways to set the breakpoint.  We can set the breakpoint in the Inspector, under the Disc/Volume tab.  Select Dual, next to Layer Options.  Or most likely you will be setting your breakpoint directly off of a marker.
