New Features in DVD Studio Pro 4.1 Following are the new features in DVD Studio Pro 4.1. Support for PowerPC-Based and Intel-Based Macintosh Computers This version of DVD Studio Pro is designed to run natively on both PowerPC-based and Intel-based Macintosh computers. HD DVD-Video Specification Version 1.0 Compliance This version of DVD Studio Pro complies with version 1.0 of the HD DVD-Video specification. Important: This document includes updated information regarding compliance with the 1.0 version of the HD DVD-Video specification. See the Late-Breaking News document, available from the DVD Studio Pro 4.1 Help menu, for additional information about changes to DVD Studio Pro required for 1.0 specification compliance. Support for Authoring DVDs With HD Video In addition to authoring standard definition (SD) DVDs, DVD Studio Pro 4.1 adds support for authoring DVDs containing high definition (HD) video that conform to the 1.0 version of the HD DVD standard. This makes it possible for you to author DVDs using a variety of HD video sources that can be burned to either red laser or blue laser drives and played by the latest version of Apple DVD Player. See “About Standard and High Definition DVDs” on page 4 for more information.

Previous Information About New Features in DVD Studio Pro 4.0 Following is information about new features included with the DVD Studio Pro 4.0 release. Support for External Video and Audio Monitors You can now connect external video and audio monitors that can be used when simulating your project. When you author a DVD, it can be important to see the video and hear the audio with devices that closely match those that the viewer is expected to use. Being able to do this while simulating your project allows you to verify the video and audio prior to building your project and burning a test DVD. In particular: Â You see the true color based on YUV values instead of a computer monitor’s RGB values. Â You see the actual pixel aspect ratios. To display SD resolution 4:3 or 16:9 video on a computer monitor requires the pixels to be scaled, which can create or hide issues in the video. Â By connecting a suitable AC-3 or DTS decoder, you can hear surround sound audio. The video monitor uses your system’s second monitor connection (if available). For example, you could connect an NTSC or PAL monitor to the S-Video output of a PowerBook G4 computer. Note: When connected to an NTSC or PAL monitor, this video output provides only an approximation of what the video will look like when burned to a disc and played on a DVD player. Due to rendering, rescaling, and interlacing issues, you should not rely on this output as a true representation of the video quality, especially with SD projects. The audio monitor, which can include a suitable AC-3 or DTS decoder, can be connected to the computer’s optical digital audio output (also known as an S/PDIF output) or to the computer’s FireWire or USB port. Video Title Set (VTS) Editor Added DVD Studio Pro 4 now includes a VTS Editor that allows you to view and control the VTS structure of your project. Using the VTS Editor, you are now 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 minimal pauses due to the player having to move between elements in different parts of the disc. Important: The order of elements in the Outline tab no longer affects the file structure when building your project. Additionally, DVD Studio Pro 4 will now automatically create additional VTS blocks as needed to support menus with a variety of video and audio assets. For example, if you have a main menu that uses an AC-3 audio asset and a second menu that uses an AIFF audio asset, each menu is automatically placed in its own VTS.

Improved General Purpose Register Memory (GPRM) Usage When creating scripts, you may find that you could use an additional GPRM or two. DVD Studio Pro provides access to eight 16-bit GPRM registers, but you don’t always need the full 16-bits of a register. DVD Studio Pro 4 allows you to increase the number of GPRM registers by partitioning one or more of them into smaller sizes. For example, you could choose to partition GPRM 1 into four 4-bit registers. This makes it possible to greatly increase the usable number of GRPMs available when creating your scripts. Improved Motion Integration DVD Studio Pro 4 can now support specialized markers added to your Motion projects. These markers can define the loop point when creating a motion menu and the transition switch point when creating Alpha Transitions. See the Motion User Manual, in the Motion Help menu, for more information. AC-3 Encoding Added to Compressor Compressor now includes the ability to encode Dolby Digital AC-3 audio files. You can encode uncompressed audio assets containing from 1 to 5.1 channels using the Compressor batch and preset capabilities. See the Compressor User Manual, in the Compressor Help menu, for more information. Compressor Includes Distributed Encoding DVD Studio Pro 4 includes an enhanced version of Compressor that supports distributed encoding. Distributed encoding allows you to spread the encoding workload among several computers, which can greatly speed up the process. See the Compressor User Manual, in the Compressor Help menu, for more information. Support for Additional Digital Theatre Systems (DTS) Audio Formats You can now use DTS ES audio that has up to 6.1 channels, as well as audio that uses a 96 kHz sample rate and a 24-bit sample size. Important: All DTS audio imported into DVD Studio Pro must use the compacted file format, with a “.cpt” file extension. Dual-Layer Break Points Can Be Set in DVD-ROM Area In those dual-layer projects that have more DVD-ROM content than DVD-Video content, you can now set the break point within the ROM content. Menu Loop Point Feature Improved You are now able to use the menu loop point feature with any motion menu, even those with drop zones, text items, and buttons with video assets. Additionally, you can now use a script to jump to a menu’s loop point. When configuring the Jump command, an option has been added to the Script Inspector that allows you to jump directly to a menu’s loop point rather than the start point.

About Standard and High Definition DVDs Standard definition (SD) DVDs provided most viewers with their first digital video experience. The great video quality, interactive menus, and surround sound audio found on current DVDs set a high standard for viewer expectations. Meanwhile, the establishment of high definition (HD) video format standards and the increasing availability of HD broadcasts have led to more and more viewers having HD video monitors, and even higher expectations for DVDs. These expectations, along with the development of improved compression technologies and a blue laser technology that greatly increases a disc’s storage capacity, have led to the ability of recording HD video onto a DVD.

But I Thought DVDs Were Already High Definition? In addition to traditional 4:3 aspect ratio video, traditional DVDs support widescreen 16:9 video, which is often mistaken for being high definition. The 16:9 video used on current DVDs, however, is the same resolution as the 4:3 video, which is the same as the standard NTSC and PAL broadcast resolutions. The 16:9 video must be anamorphic, which makes it appear horizontally squashed when viewed on a 4:3 monitor. This leads to a logical next question—what constitutes high definition video? While most HD video formats use a 16:9 aspect ratio, what generally defines whether they are HD or not is the resolution. Video resolutions that result in more pixels per frame than are used in SD-based DVDs are considered high definition. There are two common HD vertical resolutions: 720 lines and 1080 lines (used for both NTSC and PAL). These compare to NTSC’s 480 lines and PAL’s 576 lines for SD video. As with SD-based DVDs, the scanning method used on HD-based DVDs can be interlaced, with a video frame containing one field with the odd lines and another field with the even lines, or progressive, where each frame is complete. Not all HD formats support progressive scanning, however. See “Supported Video Resolutions” on page 6 for details on supported SD and HD video formats, including frame rates and scanning methods.

About DVD Studio Pro 4 and HD Resolution DVDs In addition to supporting standard definition (SD) format video DVDs, DVD Studio Pro 4 now supports creating high definition (HD) format video DVDs. With the exception of support for HD video resolutions and the number of buttons on menus and button over video subtitles, HD projects in DVD Studio Pro 4 have the same limits as SD projects. There are two aspects to creating DVDs with HD content: what you can put into the DVD video zone and the DVD disc media. DVD Video Zone With HD Content While the contents of the DVD video zone for an HD-based DVD (HVDVD_TS) are similar to those of an SD-based DVD video zone (VIDEO_TS), there are some important differences: Â HD-based DVDs support a broad range of video resolutions, including most of those used in SD-based DVDs. See “Supported Video Resolutions” on page 6 for a complete list of supported resolutions. Â In addition to supporting SD MPEG-2 video encodes, HD-based DVDs support HD MPEG-2 and H.264 video encodes. These are discussed in “HD Video Assets” on page 7. Blue Laser Disc Media Due to the improved video resolution possible with HD video, the encoded video files for HD resolution DVDs can be larger than those used with SD resolution DVDs. For that reason, a media format based on a blue laser was designed specifically for DVD projects containing HD video. See the following table for a comparison of SD and HD disc sizes. Disc

In addition to blue laser based DVD media, an HD project’s DVD video zone can be written to DVD media based on the red lasers used by traditional DVDs. (The obvious limitation is that you will not be able to fit as much video data on the disc.) Important: SD-based DVD players are not able to play DVD projects containing HD content, whether they are on red or blue laser media.

Supported Video Resolutions All video resolutions supported by SD-based DVDs are also supported by HD-based DVDs. This means that an HD-based DVD can use an HD video resolution for the main feature, then use an SD video resolution for extras. The following list includes the SD and HD video resolutions supported by DVD Studio Pro 4. Note: MPEG-1 encoded video files are not supported in HD projects. NTSC Frame rates with an “i” indicate the interlaced scanning method; those with a “p” indicate the progressive scanning method. Resolution

Using 24 fps Video Formats Both SD and HD projects can use assets encoded at 24 fps (actually 23.98 fps), as long as they are encoded specifically with NTSC or PAL flags set. Video at 24 fps has two main advantages: It matches the film frame rate, and, in the case of NTSC, provides much smaller files due to having six fewer frames per second.

HD Video Assets There are a variety of sources for HD video assets to use in your HD projects, with the most common being DVCPRO HD and HDV camcorders.  With DVCPRO HD, once you have finished editing the video, the result will need to be encoded to the HD MPEG-2 or H.264 video format.  With HDV, which is already compliant MPEG-2 HD video, you can edit the video in Final Cut Pro 5 and import the result directly in your HD projects. DVD Studio Pro 4 supports HD video encoded using the HD MPEG-2 codec and the H.264 codec. Both of these formats are playable with the Apple DVD Player. You can use Compressor to encode video to either of these formats. When you import HD resolution QuickTime video, such as DVCPRO HD video, into DVD Studio Pro, it is HD MPEG-2 encoded using the embedded MPEG encoder. Using HDV Assets The HDV format uses MPEG-2 encoding to store HD video on a standard DV or Mini DV tape. There are two video resolutions supported by the HDV format:  1280 x 720 (720p) at 19 Mbps  1440 x 1080 (1080i) at 25 Mbps (which must be anamorphic 16:9) Imported HDV assets have the video and audio separated into elementary streams (the HDV format combines the video and audio into a single file), but are not otherwise processed or converted.

Using H.264 Assets You can use the H.264 for HD DVD presets included with Compressor to encode several supported HD and SD video resolutions for use in your HD projects. The H.264 encoder is twice as efficient as the standard MPEG-2 encoder. When compared to encoding with MPEG-2, this means that with the H.264 encoder: Â You can use a lower bit rate to get the same quality, resulting in smaller files. Â You can use the same bit rate and get better quality with the same file size. Important: DVD Studio Pro only supports H.264 assets encoded using the standard presets included with Compressor. Using DVCPRO HD and Uncompressed HD Assets Another source of HD assets for your HD projects is video encoded with the DVCPRO HD compression types or uncompressed video. DVCPRO HD video, like DVCPRO SD video, and uncompressed video cannot be used directly in your DVD Studio Pro projects. You can import them, however, and DVD Studio Pro will automatically encode them to compatible HD MPEG-2 assets using the embedded MPEG encoder. You can also encode them to HD MPEG-2 or H.264 using Compressor.
