Finishing Your DVD Project

The final touches and test your DVD
Before you burn a disc, you want to make sure that you’ve programmed all the finishing touches. Then you want to preview it in the Simulator Mode. To get to the Simulator Mode, just hit the Simulator key and you’ll get a facsimile of the interface. Use this mode to check everything from button links, jumps, start-up action and markers. DVD@ccess links will not work in Simulator mode. Once you've checked everything, you are ready to build and burn your project.

You can change the Simulator settings in the Preferences area. This will allow you to change such features as the default language, region code, resolution, and display mode.

Note that the simulator does not process "Pause after VOBU" setting on markers set on full-motion video clips. Also, because the simulator is previewing content that is not muliplexed, it sometimes will stutter. This is a problem with a preview, not your assets.

Final programming reminders:
The First Play Action:
The First Play action determines what occurs when someone puts in disc in their player. This could be a short video introduction, the FBI warning, or it could just automatically go to your first screen. Either way, you must set a First Play action in your project.

To set a First Play Action:
1. In the Outline view, click on the Disc icon.

2. A Disc Inspector dialogue box comes up.

3. Choose an item from the Inspector’s First Start pop-up menu.


Programming the Remote Control buttons
There are several keys on the remote control that you should should set so that the user can navigate around your disc using these buttons on the remote control.

To assign any asset to these remote control buttons, click on Disc icon in the outline view. Go to the Inspector, and select an asset from the pop-up menu for each button.

TITLE (this is often called main or top menu on remote controls). This should navigate to your main menu.

MENU (this usually returns users to the menu they just came from)

RETURN (where do people return to when they hit this key? This should be programmed to go to the main menu or the menu that the user just came from).

AUDIO (this button on the remote is meant to switch through alternate audio tracks). You can change it so that it goes to a specific menu that allows users to choose alternate audio tracks, though that probably will confuse a lot of users.

ANGLE (this button on the remote is meant to switch through alternate video tracks). You can change it so that it goes to a specific track, though that probably will confuse a lot of users.

SUBTITLE
(this button on the remote is meant to switch through alternate subtitle tracks). You can change it so that it goes to a specific menu that allows users to choose alternate subtitle tracks, though that may confuse a lot of users.

Programming Track and Slideshow remote buttons
Tracks and Slideshows have their own Remote Control area, located at the bottom of the Inspector window. These will default to disc settings if you do not change them.

The menu button should always bring users back to the menu they came from.




Disabling Remote Control
You can disable the users ability to control the remote control buttons. You would want to do this when the user has to watch a track, such as a copyright warning.

1. Click on the Track.

2. In the Inspector, click on the User Operations tab.

3. Check off the operations that you don't want the users to have control over with their remote.


Region Codes and Protecting Content
DVD discs are easy to copy unless you use a protection code, which will encrypt the data so that users can not copy it from a DVD to their hard drive or VHS tape. You can also set up region code so that the DVDs can only be read in certain players in certain parts of the world so that people can't pirate certain DVDs in other parts of the world.

To set the disc's region codes:

1. In the Outline view, click the disc icon to bring up the Inspector.

2. Click the Region/Copyright tab in the Disc Inspector to display the disc's region code settings.

3. Click a Region Code check box to select or deselect that region. By default, all regions are selected, which means that your DVD disc will play on any player anywhere in the world (as long as that player understands your broadcast sign, either NTSC or PAL).


Content Scrambling System (CSS) and Macrovision Analog Protection:
CSS and Macrovision Analog Protection System both allow you to scramble your data so that people can't pirate your disc. Both only work through the replication process. You can't protect the DVD-ROMs that we are burning in the classroom. However, if you're planning to replicate, you should turn on the CSS and Macrovision analog copy protection. The replicator will usually charge you a fee for this so you should talk to them about the cost before sending off the DLT tape.

To enable CSS protection:
1. In the Outline view, select the disc to display the Inspector window.

2. Click the Region/Copyright tab in the Disc Inspector.

3. Click the Copyright Management check box at the bottom.

4. Select No Copy Permitted from the Copy Generation pop-up menu.

5. Click the Format for CSS check box.

To enable Macrovision copy protection:

1. Bring up the Disc Inspector by clicking on the Disc icon in the Outline view.

2. Go to the Region/copyright tab in the Disc Inspector.

3. Click the Copy Management check box in the Disc Inspector.

4. From the Copy Generation Pop-up menu, choose No Copy Permitted.

5. From the Macrovision pop-up menu, choose a Macrovision APS type. Type 3 is recommended for NTSC video, and will add a four line colorstripe to any video that someone tries to tape from the disc.

Debugging:
You can use the debugging feature to watch what's going on with your project as you Simulate it. It will also tell you about any mistakes in linking that occur.

1. Choose Window>Log

The debugging window shows the following information:

  • last item played
  • current item playing
  • current track
  • value of each variable used in a script
  • log of each action

When you're in Simulator mode, you can also see a log of what's going on by clicking on the Info button.

 

 

 

 

 

 

VTS Editor
The VTS Editor allows you to verify and control the VTS (Video Title Set) structure of your project. Using the VTS Editor, you are able to manually assign elements to VTS blocks. This makes it possible for you to optimize the final DVD's layout so that when it's played there are minimum pauses due to the player having to move between elements in different parts of the disc.

About VTS Blocks

The contents of a video DVD are contained in one ore more VTS blocks. In DVDSP, each track and slideshow must reside in its own VTS. Additionally, each VTS has a structure to support one or more menus and one ore more scripts. Also, all DVDs have a video manager that knows the VTS structure of the disc.

All menus in a VTS must have the same video and audio settings, including formats, aspect ratios, resolution, and in the case of audio, sample size. Each VTS is limited to a maximum of 1 GB worth of menus.

DVD Play back and VTS Blocks

When you play a DVD and a jump occurs between assets, there is a slight pause as the DVD player's laser locates where to jump to on the disc.

If the track is in a different VTS clock than the menu, the laser must first jump to the video manager files and from there on to the track's VTS.

If the track is in the same VTS block as the menu, the laser is able to go directly to the track.

You can improve your disc's playback performance by keeping related elements together whenever possible. For example, you should place the scripts used with a specific track in the same VTS as the track.

Since menus often link to multiple tracks or slideshows, you will not be able to keep them together with everything they can jump to. However, you can minimize the time a DVD player spends jumping from the menu to the video manager files by keep the menus in the first VTS, which is physically located close to the video manager files.

Using the VTS Editor

The VTS Editor is located in the Outline tab. To view the VTS Editor, click on the Alternate View button. Drag the partition toward the tab's center.

You can move elements from one VTS to another by dragging. Remember that a VTS can only have one track or one slideshow but it can have multiple menus and scripts.

Jacket Pictures
Jacket picture is a special still DVD image displayed on a TV screen. It displays the title of a DVD along with a still image of the video content. This jacket picture also appears when you select the stop button on your DVD player in the middle of video playback.

Jack pictures are not required. Some DVD players cannot read them.

Once you import and set your Jacket Picture, DVDSP will generate the three different sizes that it uses and the folder that holds the Jacket Picture and put this on your multiplexed DVD.


To add a Jacket Picture:

1. Import Graphic
2. Choose the Jacket Picture graphic that you want to set from the Asset pop-up menu in the Disc Inspector Advanced Features tab.
