The most likely explanation is that you have rendered the movie at a higher resolution than your computer can play back with the QuickTime compressor (codec) with which the movie was rendered. Keep in mind that full-motion video at broadcast resolution can not be played back by most computers unless it was rendered with a QuickTime compressor designed for computer play back. Please see the "QuickTime Addendum" chapter of the documentation which discusses these issues in detail.

Yes. We strive to ensure backward compatibility with content created with older versions of QuickTime. In fact, movies created with QuickTime 1 still play today in QuickTime 7.

You can Re-encode Mpeg2 movies to quicktime for FinalCut Pro using Cleaner5.0.2 using the following settings. There is no de-interlacing, so you don't lose anything. The files increase in size 10 fold, so make sure you have enough HD space. This procedure gives you quicktime movies suitable for use with final cut. image > image size constrain to 720*480, display size normal, do not deinterlace, field dominance-SHIFT DOWN Some have had good results with their decoder cards.

Try downloading the movie to your computer and watching it locally. Sometimes choppiness occurs when we can't stream it to you quickly enough (because your connection is slow or our servers are overloaded). If you're watching an MPEG-4 that we derived from an original MPEG-2, we first reduce its size to 320 x 240 - a quarter of the resolution of NTSC video. We then translate it at 350 kbps, which is really borderline for that resolution.

VLC Media Player is the most versatile player we've found for playing the wide variety of movies found in the Archive. And, it's free! We also recommend MPlayer. MPEG2 (DVD) freeware VLC, shareware player from http://www.elecard.com, or for-pay quicktime6 plugin: http://www.apple.com/quicktime/products/mpeg2playback/ ; MPEG2 (DVD) freeware VLC ( http://www.videolan.org/ ) the for-pay quicktime6 add-on (see http://www.apple.com/quicktime/products/mpeg2playback/ ).

Use a freeware flash player available from here http://www.martijndevisser.com/blog/article/flv-player-updated

I am currently investigating this. It does work on most systems, but there are cases where it doesn't. If you have more detailled info about the cause or when this happens, please tell me.

Unfortunately not. In order to watch movies available on the Peoples Archive website, QuickTime is essential. You can download it here directly from Apple.

Not really. The reason is that only a couple of compression codecs support alpha channels which are needed to produce the effect that you see. These codecs use "lossless" compression techniques which maintain much higher image quality, but are not as efficient as lossy compression schemes like JPEG.

There are a number of reasons why this could be, but there is an easy solution to part of the problem. You can view the movies outside of the CD applications, go to the movies folder on the CD and load the movies directly into Movie Player. There is also an old-movies folder that contains Quicktime movies from the previous version of the book. In the meantime, check to see you have the latest Active X drivers and your graphics card drivers are up to date.

Every rectangular image can be saved as a QuickTime VR panorama as soon as it is wide enough with respect to its height. You simply save it and choose QuickTime .mov (or HTML QuickTime) format in the "Save as" box. But to create a perfect looking QuickTime panorama, follow these instructions: First, use a "Photo Stitching" project to stitch the photos. Choose the "Auto-Crop" and the "360? Wrapping" if appropriate.

PanaVue ImageAssembler is specialized in stitching. While it can create QuickTime VR panoramas ready for publishing on the web, it cannot edit those QuickTime movies to add features on them. long as a project and its images lie in the same directory, there is no problem moving them around. When you open up an existing project, PanaVue ImageAssembler looks to see if the images are located where they are supposed to be (according to the project).

A If you don't already have the QuickTime plug-in (a "plug-in" is a piece of software), you can download it, free of charge, from Apple Computer. It takes just a few minutes to download it onto your hard disk and install it. From then on, it will open automatically whenever you access QuickTime movies wherever you are on the Web. QuickTime software is available for Windows OS and for Macintosh OS. Click the "Get Quicktime" buttom above.

Yes, if your computer has the right stuff. The computer operating system or playback software must support regional codes and be licensed to descramble copy-protected movies. If the computer has TV video out, it must support Macrovision in order to play copy-protected movies. You may also need software that can read the MicroUDF file system format used by DVDs.

Basically I haven't been able to find an MPEG editor/converter that does what I need it to do and that I can afford. If someone knows of a good one, please let me know. Quicktime has it's downsides, that's for sure. But it probably annoys the copywrite owners much less that I'm distributing small clips instead of giant ones- so I guess that's good.

For both Gold Medal Math and Roller Typing you need at least 16 MB of RAM. GeoCycle USA requires a minimum of 32 MB. The more RAM you have the better the programs will run. To check how much RAM you have for your Macintosh, go to the upper left of the screen where the apple icon is and select About This Computer. See how much Built in Memory there is.

DWW videos come in high quality media files. Using a PC that meets the minimum requirements, you should be able to playback all movies full screen. If you do not routinely defragment your hard drive, you may experience performance problems resulting in choppy playback. It is always good practice routinely to defragment your hard drive. Be sure to use an AntiVirus program and only install programs from reputable suppliers.
