Videodisc Device Setup ═══ Ultimotion Workshop/2 Beta provides videodisc support for Pioneer laserdisc models LD-V4200, LD-V4300D, LD-V4400, and LD-V8000. The 4300D supports both the American (NTSC) and European (PAL) TV standards for storing analog video signals. Default communications settings for the players are: 8 data bits, no parity, 1 stop bit with a baud rate of 4800. The first communications port is also selected by default. These settings can be changed using the multimedia setup application if they do not match the current settings of the actual videodisc device. It is highly recommended that communication speeds at or above 4800 bps be utilized to ensure reliable and optimized performance. Baud rates of 4800 and 9600 are supported for videodisc devices. Verify that the default settings on your videodisc hardware match the settings on the Videodisc page of Multimedia Setup. To set up videodisc devices and other video sources for recording, you need to make physical connections between the video device output jacks for analog audio and video signals and the input jacks of the audio and video capture adapters installed in your system. The Pioneer LD-V8000 has a computer controllable interface and supports frame-stepped recording of video files. To set up the 8000 for frame-stepped recording, a control cable must connect the videodisc device to the asynchronous communications port of the computer. To verify the installation of the videodisc device, select the Videodisc Player object in the Multimedia folder. ═══ Ultimotion Workshop/2 Beta ═══ ═══ 1.4. Videodisc Formats ═══ A videodisc has one of two formats: CAV or CLV. Frame-stepped recording can be performed using either disc type as input. With CLV discs, some videodisc players do not show an image and therefore do not enable frame-stepped recording. This is not the case with the Pioneer 8000, which can do frame-stepped recording using either format. CAV (constant angular velocity) is the interactive format of videodiscs, which allows freeze frame and slow motion. The CAV videodisc can be addressed by chapter or by frame. A CAV videodisc can contain up to 30 minutes of video on each side of the disc. One disc holds up to 54,000 frames. With a CAV format videodisc, the angular velocity of the disc is always the same (1800 RPM), no matter what track is being read, which is similar to the way a phonograph record is played. CLV (constant linear velocity) is the format for extended-play videodiscs. The CLV videodisc can be addressed by chapter or by time. A CLV videodisc can contain up to 60 minutes of video on each side of the disc. With a CLV format videodisc, the linear velocity of the disc is constant under the laser head; thus the disc spins slower when the outside tracks are read. Note: The number of chapters on CAV and CLV discs varies, depending on the manufacturer of the disc. ═══ Ultimotion Workshop/2 Beta ═══ ═══ 1.5. Camcorder and Equipment Setup ═══ It is a simple matter to hook up a camcorder or other video source to the computer so that the video signal can be processed by the video capture adapter. Merely connect the Video Out jack of the camcorder to the input jack of the video capture adapter, using either an RCA type cable or an S-VHS cable, depending on your adapter. To determine the cable type your adapter requires, see Video Capture Adapter Table. Unlike the videodisc device, most camcorders and VCRs cannot be controlled by MMPM/2 by means of a connection to the asynchronous communications port. You might want to consider using a tripod to position the camcorder, rather than propping it on the computer. In addition to holding the camera steady, a tripod lets you adjust the angle of the camera more precisely. You also might want to invest in a directional microphone or a small microphone worn by your subject, rather than relying on the microphone of the camcorder. The camcorder microphone is far enough away from the subject for it to pick up other previously unnoticed noises in the room as well, such as air-conditioning fan noise, and the like. ═══ Ultimotion Workshop/2 Beta ═══ ═══ 1.6. Before You Install ═══ Before you begin installation of Ultimotion Workshop/2 Beta, look at the README file on the Ultimotion Workshop/2 Beta diskette. This file contains last-minute information that is required to use this product. To install Ultimotion Workshop/2 Beta, you must have already installed OS/2* 2.1 and Multimedia Presentation Manager/2 (MMPM/2). If you have just installed MMPM/2, you must shut down and restart your computer before installing Ultimotion Workshop/2 Beta. ═══ Ultimotion Workshop/2 Beta ═══ ═══ 1.7. Ultimotion Workshop/2 Beta Installation ═══ Complete the following steps to install Ultimotion Workshop/2 Beta: 1. Start your system. 2. Insert the Ultimotion Workshop/2 Beta diskette into the diskette drive. 3. Using the OS/2 command prompt, make the diskette drive the current drive.

The Ultimotion Workshop/2 Beta Installation window appears. 6. Make sure the Source Drive and Path fields contain the appropriate drive and directory specifications for your installation. 7. In the Target drive field, select the drive on which you installed MMPM/2. All features will be installed in the MMOS2 directory. 8. Initially, none of the Ultimotion Workshop/2 Beta features are selected for installation. In the Features field, select the features you want to install by clicking on their names using mouse button 1. For example, you will want to select the feature that supports your video capture adapter. And if you have a videodisc machine and want to play and record from videodisc, select Videodisc. If you change your mind about a feature selection, you can deselect it by clicking on its name again. To see all of the features, use the  key or the mouse to scroll through the list. Notice that the Features to Install field shows the current number of features selected. 9. Select Install and follow the instructions in the subsequent windows to complete the installation. During installation, you can have your CONFIG.SYS file automatically updated. If you choose not to have the file updated for you, the installation program creates a file called CONFIGCH.NEW and places it in the \MMOS2 directory of the target drive. Use this file as a reference for modifying your existing CONFIG.SYS file. You must update the CONFIG.SYS file of your computer before you can use Ultimotion Workshop/2 Beta. 10. To activate the Ultimotion Workshop/2 Beta support after installation, you must shut down your computer and then restart it. Make sure the installation program has completed, and remove any diskettes from the diskette drive. Do the following to shut down your computer: a. Move the mouse pointer to an empty area on the OS/2 desktop. b. Press mouse button 2. c. Click on the Shutdown choice. Warning: Always use the Shutdown procedure before turning off your computer or restarting it. You can lose information if you turn off your computer without using Shutdown. Restart your computer. The folder on your desktop now includes the Ultimotion Workshop/2 Beta features you selected. ═══ MINSTALL Program ═══ ═══ 2. Using the Digital Video Recorder ═══ The Ultimotion Workshop/2 Beta Recorder converts your desktop into a video workshop. The following sections describe how you can use the recorder to: o Record in real time from an analog video source, such as a camcorder, videodisc, or videotape device. o Record from a frame-steppable source to produce high-quality motion video. o Open a monitor window to preview the video source. o Use PM dials to adjust color, tint, contrast and brightness. o Specify a size and position on the source for the capture. o Set frame rate values. o Set quality values for audio and video. o Convert a video file to another compression format o Cut, copy, and paste video files. o Capture a bit map from a video source. Note: Converting a video file to another compression format is not supported in this Beta. ═══ Ultimotion Workshop/2 Beta ═══ ═══ 2.1. Recording Methods ═══ The Ultimotion Workshop/2 Beta recorder supports real-time recording and frame-stepped recording. Real-time recording is the most commonly used recording method, because it can be done using the signal of a camcorder or a VCR, with no source preparation requirement. Ultimotion Workshop/2 Beta supports the simultaneous capture of audio and video, with the interleaving of the audio and video done in real time. Real-time recording is supported for a wide range of videodisc and videotape devices as input-from the high-end frame-steppable, computer-controllable device to the low-end device with no computer interface. Frame-stepped recording requires input from a videodisc device that has frame-stepping capability and a computer-controlled interface. An example of such a device is the Pioneer** LaserDisc Model LD-V8000, and other input device types will be added in the future. Because frame-stepped recording is done frame-by-frame from the source to the target, more time is used to record and compress the video data, resulting in a high-quality movie file. ═══ 2.2. Video File Format ═══ The Ultimotion Workshop/2 Beta Recorder supports recording in the AVI file format. The Audio/Video Interleaved (AVI) file format is the standard file format used to support software motion video. AVI files can contain multiple streams (tracks) of data (for example, a video and an audio stream). The streams can be interleaved to improve access times during playback. The present implementation is limited to a single video stream and a single, optional, audio stream. ═══ 2.3. Default Recorder View ═══ The Ultimotion Workshop/2 Beta Recorder provides a default view and an input/output view. The default view is intended for a simple recording, playback, or editing operation; for example recording using the analog signal from a VCR or camcorder and your video capture adapter. ═══ Ultimotion Workshop/2 Beta ═══ ═══ 2.4. Input/Output Recorder View ═══ The input/output view is for more complex recording and editing operations. For example, you might be recording from videodisc input to a hard disk file output. The input/output view lets you mark an area on the input slider to indicate the portion of the videodisc input you want to record, and then record and play back the output. The input/output view also allows you to use input and output files in an editing operation. For example, you can copy all or part of an input file to a location or a marked area in the output file. ═══ Ultimotion Workshop/2 Beta ═══ ═══ 2.5. Device Selections Window ═══ The input/out view is displayed after you select an input device from the Device Selections window. Choose Device selection on the Options menu to make your device selections. When the input/output device is displayed, selection of None as the input device causes the default view to be displayed. Note that Digital Video 2 is selected as the output device. This is the default output recording device. Selecting Digital Video Player as the input device enables you to load an AVI file as input for recording and editing purposes. You can use the File menu choice to load an AVI file as output and copy the entire input file or only a portion of it into a location in the output file. You also can select devices for the recorder by using drag and drop techniques. For example, you can pick up a movie file and drop it on the recorder in the input or output area. If you make no device selections, the default view of the recorder is displayed. ═══ Ultimotion Workshop/2 Beta ═══ ═══ 2.6. Time Formats ═══ When you load a file or a videodisc, values for the beginning and end of the file are shown on the media position slider in the current time format. The box to the right of the media position slider shows the current position in the file. When you mark an area of input or output for editing or recording, the beginning and end marks are shown in the current time format. A time format helps you measure distance within a file from one position to another. The Ultimotion Workshop/2 Beta Recorder supports two formats: HH:MM:SS:FF and frames. The HH:MM:SS:FF time format measures file length in hours, minutes, seconds, and a frames-per-second count. The frames time format measures file length using a consecutive frame count. The HH:MM:SS:FF time format is useful for determining the number of frames per second you are actually capturing. If you are not capturing the desired frame rate per second, you can experiment by adjusting video and audio quality settings to attempt to boost the frame rate. ═══ Ultimotion Workshop/2 Beta ═══ ═══ 2.7. Changing the Time Format ═══ The time format can be changed at any time with no effect on the data. To select a time format for the movie file you are recording: 1. Select Options. 2. Select Input Time Format or Output Time Format. 3. Select one of the time formats available to you: o HH:MM:SS:FF o Frames ═══ Ultimotion Workshop/2 Beta ═══ ═══ 2.8.

Related Topics o Marking Methods ═══ Frame-Stepped Recording ═══ ═══ 2.9.11. Recording the Movie ═══ After you have set up your devices for recording, opened a monitor window, made your video adjustments, and set start and stop positions, you are are ready to capture the marked videodisc segment as a new file. (By default, the output device is already set up to record a new file.) Press to record. The capture is done in a two-pass operation: 1. While the external device plays, audio is recorded in real time, until the end mark is reached or the Stop button is pressed. 2. The external device is then repositioned to the starting position and video is recorded and compressed frame by frame, with each frame being interleaved with audio after it is compressed. The status line indicates when recording and compression are taking place. As an alternative to setting an end mark, you can press the Stop button when the desired position in the videodisc source is reached. Pressing the Stop button ends the the first pass (audio recording) and starts the second pass (video recording). Video capture starts at the beginning mark and continues up to the position where Stop was pressed. There is no need to press the Stop button if you set an end mark, or if you want recording to continue to the end of the source medium. To save the recording as an AVI movie file: 1. Select File. 2. Select Save as. 3. Select the Movies directory. 4. Type the AVI filename in the Save as filename field. The file should have an AVI extension so it can be associated with the Digital Video player. 5. Select OK. Wait until the hard disk stops before closing the recorder. The blinking of the hard disk light indicates that interleaving of the audio and video is taking place. If you close the recorder too soon, you can corrupt the AVI file. ═══ Frame-Stepped Recording ═══ ═══ 2.9.12. Playing the Movie Clip ═══ To play the new movie clip: 1. Open the Movies folder. 2.

Preparation for Recording Live Video ═══ Following are some guidelines for equipment you might want to use and planning you might want to do before you record a live movie using a camcorder and the Digital Video Recorder. Topics include: o Setting up the camcorder o Adjusting the lighting o Planning the video production ═══ 2.12.1. Lighting ═══ Bright overhead light in a room can cast unwanted shadows. Fluorescent lighting can make everything look pale and washed out. Too much light or too little light on the subject can be equally problematic. Use of portable, low-wattage lights with reflectors can compensate for lighting problems. Place the lights outside the range of the camera and position them so that they are angled neither too high or too low on the subject. In addition, make sure the lights do not shine directly into the subject's eyes. Not only can this cause the subject some discomfort, it also can cause light to be reflected from the eyes. You can "white balance" your camera for the lights you are using by aiming the camera at a white piece of paper that is positioned where your subject will be, and pressing the white balance button. ═══ 2.12.2. Planning the Video Production ═══ A little bit of planning can often make the difference between a home video and a quality video production. A useful planning tool for video production is the storyboard concept, which uses a series of frames to describe the major audio and video elements that comprise a video production. The storyboard can be used at various levels during the video production. For example, a storyboard can provide a high-level overview of the entire video production. A storyboard also can provide a detailed description of a scene, where each frame of the storyboard represents a change that takes place during the scene-such as the entrance of a new character or a change in the camera angle. Another video production tool is the script. A script defines the message you want your video to communicate. Avoid lengthy dialog and be sure your script includes enough stage direction to help your subjects convey the message you want. ═══ 3. Using the AVI File Utility ═══ The AVI File Utility is a PM application that allows you to: o View information within the AVI file such as header information, chunk, index, RIFF format, and general statistics associated with the file. o Merge an audio file with an AVI file o Split the AVI file into an audio file and an AVI file (without sound) o Change the interleave ratio of audio and video frames o Change the skew between the audio and video o Add or remove 'Junk' chunks, 'rec' chunks, and an index from the AVI file The main window of the AVI File Utility consists of a static entry field for status messages, a Multi-Line Entry (MLE) for viewing AVI file information, and Merge, Split, Interleave, Skew, and Cancel push buttons.

Menu Choices ═══ This section describes the menu choices available from the AVI File Utility. The Help Menu is not implemented for the Ultimotion Workshop/2 Beta. ═══ AVI File Utility ═══ ═══ 3.2.1. File Menu ═══ The File menu contains options which control the input and output of AVI and audio files. You can select from the following menu choices. Open... Opens the AVI file specified in the file selection window. When you select a file, the program generates a new set of display information for the file and updates the main window. Save Saves the file with its current file name. Save As... Saves the current file with a name you type. The file can be a new file, or an existing file whose name, path, or driver letter you want to change. This allows you to create a new AVI file name, instead of overwriting the existing file. Open Audio File... Opens the audio file specified in the file selection window. You can load an audio file to merge with an AVI file. Save Audio File... Saves an audio file that was split from an AVI file. ═══ Ultimotion Workshop/2 Beta ═══ ═══ 3.2.2. Edit Menu ═══ The Edit menu contains actions associated with modifying the AVI file in memory. These actions modify the current AVI file and update the main window with the characteristics of the new AVI file. You can select from the following menu choices. Merge Audio with Video Merges an AVI file and an audio file that were previously loaded. Split Audio from Video Removes the audio track and stores it as a separate file in memory, if the current AVI file in memory has an audio track. You can then save this file as a separate audio file. Change Interleave Ratio Allows you to select a interleave ratio to use for the current AVI file. This interleave ratio is the ratio of video to audio frames. Change Audio Chunk Skew Allows you to select a new skew value for the current AVI file. The skew value is the number of frames that the audio stream leads the video stream in the AVI file. Having the audio stream lead the video stream allows the audio buffers to stay full as the movie is played. Options Allows you to apply one or more of the following options: 'Junk' Chunks Adds padding (filler) to the records within the AVI file so that all the records are multiples of 2KB. Use this padding (known as a 'Junk' chunk) for easier reading of the AVI file. 'rec' Chunks Adds 'rec' chunks to the AVI file. This type of chunk surrounds the audio and video chunks of the current frame. Index Adds an index to the end of the AVI file. This index contains the offset and length of each individual chunk within the AVI file. ═══ Ultimotion Workshop/2 Beta ═══ ═══ 3.2.3. View Menu ═══ The View menu contains options that control the display of AVI file information as it is displayed in the main window. You can select from the following menu choices. Chunk ID and Length Displays information associated with each individual chunk in the file. This information consists of the ID, the length, and the offset of the chunk. Headers Displays information in the various headers of the AVI file. For example, the main AVI header and the AVI stream header. Index Displays information contained in an index chunk of an AVI file. The index chunk is an optional part at the end of an AVI file. It specifies the location of the data chunks within the file and is required to support seek and edit operations. Status Information Displays AVI file statistics such as frame rate and the average size of the frame. Packed Determines if all the information displayed is shown in a packed or unpacked form. The packed form squeezes the data as much as possible by removing a large part of the textual information. RIFF Format Displays only the RIFF format of the current AVI file. All previous selections are ignored. Decimal Makes numbers appear as decimals when displayed in the main window. hexadecimal Makes numbers appear as hexadecimals when displayed in the main window. ═══ Ultimotion Workshop/2 Beta ═══ ═══ 4. Glossary ═══ ═══ Glossary ═══ Select the starting letter of the glossary term you want to locate. ═══ A ═══ asymmetric video compression In multimedia applications, the use of a powerful computer to compress a video for mastering so that a less powerful (less expensive) system is needed to decompress it. Contrast with symmetric video compression. audio Pertaining to the portion of recorded information that can be heard. audio attributes Refers to the standard audio attributes: mute, volume, balance, treble and bass. audio segment A contiguous set of recorded data from an audio track. An audio segment might or might not be associated with a video segment. audio track (1) The audio (sound) portion of the program. (2) The physical location where the audio is placed beside the image. (A system with two audio tracks can have either stereo sound or two independent audio tracks.) AVI file format The Audio/Video Interleaved (AVI) file format is the standard file format used to support software motion video. AVI files can contain multiple streams (tracks) of data (for example, a video and an audio stream). The streams may be interleaved to improve access times during playback. The present implementation is limited to a single video stream and a single, optional, audio stream. ═══ B ═══ balance For audio, refers to the relative strength of the left and right channels. A balance level of 0 is left channel only. A balance level of 100 is right channel only. brightness Refers to the level of luminosity of the video signal. A brightness level of 0 produces a maximally white signal. A brightness level of 100 produces a maximally black signal. ═══ C ═══ camcorder A compact, hand-held video camera with integrated videotape recorder. capture To take a snapshot of motion video and retain it in memory. The video image may then be saved to a file or restored to the display. CAV See Constant Angular Velocity. chrominance (1) The signal which represents the color components of the video, such as hue and saturation. (2) See also luminance. chunk (1) The basic building block of a RIFF file. (2) A RIFF term for a formalized data area. There are different types of chunks, depending on the chunk ID. (3) See junk chunk or RIFF chunk. clip A section of recorded, filmed, or videotaped material. clipping The bounding of an area to limit the visible portion of video or graphics. CLV See Constant Linear Velocity. CODEC compressor/decompressor (CODEC) - An algorithm implemented either in hardware or software that can either compress or decompress a data object. For example, a CODEC can compress raw digital images into a smaller form so that they use less storage space. When used in the context of playing motion video, decompressors reconstruct the original image from the compressed data. This is done at a high rate of speed to simulate motion. color See saturation. connection (1) The establishment of the flow of information from a connector on one device to a compatible connector on another device. A connection can be made that is dependent on a physical connection, for example the attachment of a speaker to an audio adapter with a speaker wire. A connection can also be be made that is completely internal to the PC, such as the connection between the waveaudio media device and the ampmix device. (2) See also connector. connector (1) A software representation of the physical way in which multimedia data moves from one device to another. A connector can have an external representation, such as a headphone jack on a CD-ROM player. A connector can also have an internal representation, such as the flow of digital information into an audio adapter. (2) See also connection. contrast The difference in brightness or color between a display image and the area in which it is displayed. A contrast level of 0 is minimum difference. A contrast level of 100 is maximum difference. Constant Angular Velocity (CAV) (1) Refers to both the format of data stored on a videodisc and the videodisc player rotational characteristics. CAV videodiscs contain 1 frame per track. This allows approximately 30 minutes of playing time per videodisc side. CAV videodisc players spin at a constant rotational speed (1800 rpm for NTSC or 1500 rpm for PAL) and play 1 frame per disc revolution. CAV players support frame accurate searches. (2) See also Constant Linear Velocity (CLV). Constant Linear Velocity (CLV) (1) Refers to both the format of data stored on a videodisc and the videodisc player rotational characteristics. CLV videodiscs contain 1 frame on the innermost track and gradually increase to 3 frames on the outermost track. This allows approximately 1 hour of playing time per videodisc side. CLV videodisc players vary the rotational speed from approximately 1800 at the inner tracks to 600 rpm at the outer tracks (for NTSC). Currently, few CLV players support frame accurate searches. They only support search or play to with in one second (30 frames for NTSC or 25 frames for PAL). (2) See also Constant Angular Velocity (CAV). contrast The difference in brightness or color between a display image and the area in which it is displayed. A contrast level of 0 is minimum difference. A contrast level of 100 is maximum difference. cut The procedure of instantly replacing a picture from one source with a picture from another.

Digital data may be stored in data files. ═══ E ═══ fps Frames per second. frame-accurate searching The capability of a videodisc player to search for and play specific frames on the videodisc by means of software or remote control. This capability is available on all CAV players but only a few CLV players. Searching by most CLV players is accurate only to within one second of a frame. frame number The number used to identify a frame. On videodisc, frames are numbered sequentially from 1 to 54,000 on each side and can be accessed individually; on videotape, the numbers are assigned by way of the SMPTE time code. frame rate The speed at which the frames are scanned-30 frames a second in NTSC video, 25 frames a second in PAL video, and 24 frames a second in most film. frames A complete television picture frame is composed of two scanned fields, one of the even lines and one of the odd lines. In the NTSC system, a frame has 525 horizontal lines and is scanned in 1/30th of a second. In the PAL system, a frame has 625 horizontal lines and is scanned in 1/25th of a second. freeze (1) Disables updates to all or part of the video buffer. The last video displayed remains visible.

(2) Also referred to as tint. ═══ I ═══ interlacing A characteristic of video image display that results in greater image clarity. In effect, the video image is traced across the screen twice. (The time delay between the two tracings makes this effect undesirable for normal computer-generated graphics.) Synonymous with interleaving. interleave To arrange parts of one sequence of things or events so that they alternate with parts of one or more other sequences of the same nature and so that each sequence retains its identity. interleaving (1) The simultaneous accessing of two or more bytes or streams of data from distinct storage units. (2) Synonym for interlacing. ═══ J ═══ junk chunk Represents padding, filler or outdated information. It contains no relevant data; it is a space filler of arbitrary size. ═══ L ═══ line audio The standard type of audio signal distributed between most components of an audio system. luminance (1) The signals which represent the brightness components of the video.
