Understanding dual layer and dual side discsAdobe Encore DVD supports creating projects for dual-layer discs and dual-side discs. These discs, however, cannot be burned by a conventional DVD burner. To create a dual-layer disc, you first must write your project to two separate DLT tapes (Digital Linear Tape), one tape for each layer of the disc. See Build Options. For dual-side discs, you must create two seperate projects and write each one to its own DLT. Then you must take the DLTs to a replication facility to actually create the DVD. See Replicating DVDs. You can also create a dual-side, dual-layer disc. In this case, you would build two projects, each producing 2 tapes. The first two tapes would represent the two layers of the first project. The other two tapes would represent the two layers of the second project. One very important consideration for creating dual-layer discs is determining where, during playback, the DVD player will switch from the first layer to the second. This transition is called a layer break, and, if improperly placed, can make the layer break appear jerky. Adobe Encore DVD will automatically set a smooth layer break if it finds a spot between timelines or menus that corresponds closely to the end of the disc layer. If there isn't a spot that satisfies these requirements, then the program asks you to choose a chapter point within a specified, appropriate range. |
