Spigot AV Read Me

Spigot™ AV Read Me These notes contain information about the Spigot AV 1.1 software for SpigotPro™ AV and SpigotPower™ AV that was not available when the manual included with your card was printed. Please read the manuals and these notes before you start to work with your SpigotPower AV or SpigotPro AV. In this document, all mentions of Spigot AV are referring to both SpigotPro AV and SpigotPower AV products. This version of the software is recommended for use with the Quadra™ 840AV, and the Quadra and Centris™ 660AV only. No other AV Macintosh computers are supported by version 1.1 of the Spigot AV software. Use of this software on unsupported AV Macintosh® computers is at your own risk. The Spigot AV 1.1 software requires QuickTime 2.0 and the Apple Multimedia Tuner 2.0.1. These are included with the Spigot AV software disks. We recommend that users of System 7.5 install the System 7.5 Update 1.0. We recommend that users of System 7.1.1 (which is shipped on the Quadra 840AV and the Quadra and Centris 660AV) install System Update 3.0. Both updates contain AV enhancements and corrections for Quadra and Centris AV computers. Capturing Video Dropping Frames It is important to set your data rate to a throughput supported by your scratch disk. If the data rate is set too high, your captured clips will show dropped frames, torn or discolored frames, and audio stuttering on playback. To correct this, lower your quality setting or data rate until a captured clip plays smoothly. The following items will also reduce the likelyhood of dropping frames: 1. Turn off EtherTalk, by switching to LocalTalk in the Network control panel. 2. Turn off AppleTalk in the Chooser. 3. When using System 7.5, turn off the Menubar clock in the Date & Time control panel 4. Removing hierarchical file menu extensions, such as Now Menus and Apple Menu Options 5. Removing any extensions that are not necessary for capturing and playing back video. Cropping Most video applications let you crop video as you capture it. If you crop video on an AV Macintosh with a Spigot AV product installed, however, the AV Macintosh computer will process your capture through the built-in video digitizer, rather than through the Spigot AV software. Since the Spigot AV software enhances the video capture capability of the built-in video digitizer in an AV Macintosh computer, your frame rate will be noticeably lower when the built-in digitizer is used. Capture Sizes Spigot AV lets you capture video at full- or quarter-screen NTSC (640 x 480 and 320 x 240) and PAL (768 x 576 and 384 x 288) sizes. If you select an unsupported size, your AV Macintosh -1- computer will process your capture through the built-in video digitizer, rather than through Spigot AV, and your frame rate will be noticeably lower. Capturing to RAM You can capture video to your computer’s RAM, then save it to your hard disk for permanent storage. While this may let you capture…
