T454 Week 11 - Spring 2006 Agenda:
Announcements/Observations
Review: Chapter Markers can only be placed on I frames (which occur every 15 frames, or at the beginning of a GOP) You can create chapter markers in FCP and export them to bring into DVDSP via Compressor. This is desirable because you can specify precisely where the makrer can go. (In FCP press the M key twice to set a Marker and bring up the Marker editor window.) To create a marker within DVDSP:
You can navigate from marker to marker by pressing control-left arrow and control-right arrow. Markers can be named with the Inspector You can move and delete markers easily. Try dragging them left or right. You can move a marker with timecode in the Inspector Cell markers are markers that a DVD remote will ignore. They can be used for scripting, and turning buttons off and on, and to define in and out points for mixed angles Create these by selecting your marker in the track editor. Then in the Inspector, deselect all three "type" checkboxes. Stories work like playlists. They are a collection of chapter markers. By creating a story, you can navigate through any series of chapters you like in any order you choose. You can even repeat certain chapters. In-class story exercise In this exercise you will create a DVD with a single track that contains a story. The DVD will have a menu with two buttons. One will play the track "normally," the other will play the chapters out of order by using the story feature. Unless you have something better to use, try using the supplied countdown movie. It is short and will easily show the chapters playing in or out of sequence. Open the Countdown movie in either FCP and set chapter markers in between each number. Export via Compressor, bring it into DVDSP, and create a track out of it. Create a story that either skips numbers, counts backwards or does both. Make a menu with two buttons. One should play the track in order, the other will play your story Build your project and test it. When you are satisfied that it works, place it into your week 11 folder into a folder called "story." (It'll be called Video_TS) Menus You can create two types of menus in DVDSP
Layer menus are slower to respond than overlay menus, but allow you to use multi-layered Photoshop documents to create interesting pop-up tye "mouseover" effects. The major down side is that you can't use audio. You can use the "add layered menu" command or press Shift-command-Y Overlay (a.k.a. highlight) menus allow you to use images or movies as the background. An overlay image is used to define the buttons or areas that repond to user's selections. Overlay menus can have audio and video. In DVDSP using the "add menu" command creates a new overlay menu. (command-Y) They look slightly different in the outline view. Button Hotspots are the areas that define a button's activation area. At this point in time, button hotspots must be rectangular and should not overlap with other buttons. This imposes certain design constraints you should be aware of. You should name your buttons with the Inspector and also set targets for them. Functions:
Motion Menus: Looping & Timeout Actions Audio or Video files can be set to either loop or have a timeout function. Assigning timeouts If the viewer doesn’t do anything after a specified period of time, you can have your DVD do something (play the demo, start the movie etc) To do this, select the "At End" property in the Inspector and tell it what to do after it times out. Then put in a number of seconds before performing the action Setting Default Buttons Default buttons are the buttons that are already selected when entering a menu. By default it will be the first button, but you will probably want to change this. Setting the default button: Select a menu and in the Inspector, click on the menu tab. You'll see the Default Button” option. Set this to be the button you want activated when a user comes to your menu. (eg Play on a DVD menu). You can have no button selected by choosing “Not Set” from the Default Button Menu. Return Button - You can set what happens if someone presses the return button on the remote control Highlight condition When you activate a button from a menu, you will jump to a track, or perhaps play an audio or subtitle stream, etc. Conditions allow the menu to have the same button selected when the user comes back to it. In order to work every single button on a menu must have the conditions set for it. To do this: Select a button. Under “Selection Type” (under Selection Condition”) Select the type of item to look for (Track, Audio Stream, or Subtitle Stream) Button Navigation You can leave it to DVDSP to control how users navigate from one button to the next, or you can set it yourself (preferable). To ensure the best usability, check to make sure your button navigation functions intuitively. If buttons are in a row, users expect to be able to use the direction keys to navigate accross the row. Before you try to set the button navigation, name your buttons so you can easily determine what they do. There are several ways you can set button navigation in DVDSP:
Rulers & Guides Ruler units and guides can be set in the Preferences. Guides work like in Photoshop- you can drag them in from the edges. Dynamic guides work like those in Motion.
Review any Layer Menu Issues Place functioning layer menus into a "homework" folder Thursday------------------------------------------- Highlight Menus and Overlay images If you don't use an overlay image (grayscale PICT image) your highlight menu will look dorky & chunky. All you will be able to do is create rectangles that light up. DVD Studio Pro lets you use a simple overlay (one color)
or multicolor In Photoshop, you can make your overlay images with either a grayscale image or with chroma (color) mapping
Overlay images should be saved as single layers TIFs or PCTs. In DVDSP, you can use a Highlight Set, which is a group of colors used for the button's, normal selected and activated states. Since you can specify 4 colors per state- and there are three states- this gives you up potentially up to 12 different colors. Don’t forget to assign an action to your button. You can do this with the Inspector. Menus with Audio You can add audio by selecting the Menu tile, then choosing an audio file from the audio menu. It's best to deisgn your motion menu with the audio in mind with the video. An easy way to do this is to create or composite it in Final Cut Pro. This way your audio will match your video seamlessly. Creating multicolor highlights You need to turn off “Use Simple Overlay”. You can then
set the various Motion Menus To create motion menus: Since you need a video clip and an overlay image to make a motion menu, first think about & design your menu. You may want to design your menu in Photoshop, but composite it in After Effects, FCP or Motion. If you use Photoshop to design your menu, you can easily export an overlay image. You can also bring your Photoshop file into After Effects as a comp, and have it serve as a template to composite your video clips with. Remember, if you use AE, you'll need to render out a quicktime movie, and use FCP, Quicktime Pro, or Compressor to convert it into an MPEG-2 stream sized at 720 x 480. Also don't forget to consider your audio.
Motion menu transitions How could you approach a menu that fades up from black and then loops? Homework:
