- QuickTime MPEG Extension Version 1.0.1
-
- Introduction
-
- The QuickTime MPEG extension works directly with QuickTime
- to provide complete playback and control of MPEG movies.
- After you've installed the extension, each time you open an
- MPEG movie, QuickTime will automatically open the MPEG movie
- into a QuickTime movie containing a single MPEG track. This
- one MPEG track references both the video and audio streams
- of the original MPEG movie.
-
- Note: This version of the QuickTime MPEG extension enables
- playback of MPEG-1 files. You cannot use the QuickTime MPEG
- extension to convert QuickTime movies into MPEG files.
-
- System requirements
-
- To install and use the QuickTime MPEG extension, you must
- have the following:
-
- * A Power Macintosh computer * QuickTime 2.5 or later
- (available at http://quicktime.apple.com/sw/ ) *
- Approximately 2.5 megabytes (MB) of free memory per MPEG
- bitstream (for optimal playback)
-
-
- Installing the software
-
- The QuickTime MPEG Installer places the QuickTime MPEG
- extension in your System Folder. It also installs the
- MoviePlayer application in a new QuickTime folder on your
- local hard disk. The MoviePlayer application can be used to
- play QuickTime content as well as MPEG files. The Installer
- also installs Thread Manager 2.1.5. This version of the
- Thread Manager is required to use the QuickTime MPEG
- Extension.
-
- To install the software, follow these steps:
-
- 1. Double-click the Installer icon to open it. 2. Read the
- message that appears, then click Continue. 3. In the window
- that appears, read the software license agreement, then
- click Agree. 4. In the dialog box that appears, make sure
- Easy Install is selected in the pop-up menu. Then click
- Install. Note that by installing the software, you accept
- the terms of the license agreement. 5. When the installation
- is complete, click Restart.

- What's new in QuickTime MPEG v.1.0.1?
-
- * The QuickTime MPEG extension has been enhanced to fully
- support the MPEG media produced by Hitachi's MP-EG1A digital
- camera. Using this software, it is now possible to open and
- play MPEG layer-I audio-only files (filenames that often end
- with ".MPA"). Additionally, when opening these MPEG audio
- files, QuickTime will now automatically search for
- still-image files that having the same name but ending with
- either a ".JPG", a ".JPA", or a ".GIF" suffix. QuickTime
- will automatically combine the still image file and
- associated audio file into a single movie. This behavior
- greatly simplifies working with files created by the Hitachi
- camera when it is in "audio-annotated still-image" mode.
-
- * The QuickTime MPEG extension has been enhanced to support
- MPEG-1 still image files on VideoCD discs. Using this
- software, QuickTime can now open these VideoCD image files.
-
- * Previously, it was not always possible to access all the
- MPEG files on a VideoCD if that disc contained more than 32
- MPEG files. With this version of the software, this
- limitation has been fixed.
-
- Using the software
-
- * Playback performance depends on your model of computer. A
- Power Macintosh 7100/80Mhz/601 will achieve approximately
- 10-12 frames per second (fps) playback at a window size of
- 320 x 240, while a Power Macintosh 8500/120MHz/604 will
- achieve approximately 24 fps at a window size of 320 x 240.
-
- * For best performance, make sure your sound output is set
- to 44.1 kHz, 16-bit stereo and your video monitor is set to
- 256 or thousands of colors (thousands of colors will usually
- produce the best combination of image quality and playback
- performance). Turn virtual memory and RAM Doubler off.
-
- * Some MPEG files are encoded at 15 or at 7.5 fps instead of
- the normal 30 or 24. If your file appears to be playing much
- too fast, rename the file ".m15" and/or ".m75" and see if
- either of those speeds looks correct. For example, rename
- the file "movie.mpg" to "movie.m15" or "movie.m75."
-
- * After you've installed the QuickTime MPEG extension, you
- can use the QuickTime Plug-In v1.1 (available at
- http://quicktime.apple.com/sw/ ) to view MPEG movies within
- your Web browser application (such as Netscape Navigator).
-
- * At larger window sizes, QuickTime utilizes a performance
- optimization called "black-lining". With black-lining, only
- every other image line is drawn to the screen. Utilizing
- this technique, significant playback performance
- improvements can be achieved on some systems.
-
- In some situations, it may be preferrable to disable
- black-lining. This can be achieved by turning "High-Quality"
- playback mode using the following steps:
-
- 1) Using the MoviePlayer application, choose the Get Info
- item from the Movie menu.
-
- 2) Choose the "MPEG Track" menu item from the leftmost
- pop-up menu in the "Get Info" window.
-
- 3) Choose the "High Quality" menu item from the rightmost
- pop-up menu.
-
- 4) Click on the check box item to select High-Quality mode.
-
- 5) Close the "Get Info" window.
-
- 6) Black-lining should now be disabled.
-
- Note: If you save this modified movie, it will automatically
- use High-Quality playback mode the next time it is opened.
-
- * The QuickTime MPEG extension currently supports layer-I
- and layer-II audio streams.
-
- * To play a .DAT file from a CDi or a Video CD, you must
- open the file from within MoviePlayer by choosing Open from
- the File menu. Dragging and dropping the file onto your
- hard drive or onto the MoviePlayer icon will result in an
- error. Double-clicking the file will also result in an
- error.
-
- * You can find the latest versions of the QuickTime MPEG
- extension and other QuickTime software at the QuickTime
- (WWW) Software site, located at:
- http://quicktime.apple.com/sw/
-
- Known problems
-
- * The QuickTime MPEG Extension is not currently compatible
- with other QuickTime MPEG playback solutions. If you have an
- Apple or third-party MPEG hardware playback card installed
- in your computer and you wish to continue to use it, you
- should remove the QuickTime MPEG Extension from your
- Extensions folder to use your card.
-
- * Some non-Apple CD drivers may have problems reading CDi
- and Video CD discs. Apple is working with third-party
- CD-ROM vendors to solve this problem.
-
- * CDi and Video CDs with dual audio tracks encoded in the
- separate stereo channels may play one track out of each
- speaker. We are working to fix this problem in a future
- release. Please use the MoviePlayer Get Info (Command-I)
- option to access the MPEG track. Choose Volume, and adjust
- the pan control all the way to the left or the right.
-
- * ClarisWorks' Text Preview extension (installed by
- ClarisWorks 3.0 and 4.0) interferes with the MPEG file
- preview. When you open an MPEG file, the Open dialog box
- displays text symbols rather than a movie clip in the
- preview window.
-
- * The Apple Video Player application does not currently play
- the sound in an MPEG movie.
-
- * The MPEG version of Activision's "Return To Zork"CD-ROM
- title is not currently compatible with the QuickTime MPEG
- extension.
-
- * The Performa 6205CD may hang or freeze when playing long
- CDi or Video CD MPEG movies. We are working to solve this
- problem.
-
- * Some third-party audio boards may interfere with
- audio/video synchronization. If you are having
- synchronization problems and are not using the internal
- sound output, changing to the internal sound device should
- fix the problem.
-
- * Video CDs with audio tracks are encoded in such a way that
- the Audio CD Access extension prevents you from seeing the
- MPEG movies. Remove the Audio CD Access extension, restart
- your computer, and you should be able to see the MPEG movies
- on such a disc.
