To view the grid, click the down arrow next to the Overlays button ( ) and choose Grid. Set the grid spacing using the Horizontal grid divisions and Vertical grid divisions settings on the Video tab in the Preferences dialog. Isolating color channels The Video Preview window allows you to select a specific channel to be isolated and whether the channel should be displayed in grayscale only. To display a channel, click the down arrow next to the Overlays button ( ) and choose a color channel. Note: Use the Alpha as Grayscale setting to isolate the Alpha channel mask and display it in grayscale. Monitoring video with scopes Video scopes are only available in the full version of Vegas software. From the View menu, choose Video Scopes to toggle the display of the Video Scopes window. Broadcast video uses a narrower range of color than the RGB you see on your computer. When you broadcast a project that contains out-of-range colors, you can introduce image problems or even noise into the audio stream. Use the scopes to analyze the your video and adjust accordingly with the Brightness and Contrast, Broadcast Colors, Color Corrector, Color Corrector (Secondary), and Levels plug-ins before rendering. Choose a setting from the drop-down list to choose which scope you want to display. Choose settingDisplay video scopes settings Update scopes while playing

260 PREVIEWING AND ANALYZING VIDEOCHP. 15 Note: If your video hardware will add a 7.5 IRE setup, click the Settings button () and select the 7. 5 I R E S e t u p check box in the Video Scopes Settings dialog. Black will be displayed as 7.5 in the waveform monitor. If your video hardware does not add a 7.5 setup, clear the check box, and black will be displayed as 0. Displaying chrominance using the vectorscope monitor The vectorscope monitor in the Video Scopes window allows you to monitor the chrominance (color content) of your video signal. The monitor plots hue and saturation on a color wheel. The vectorscope displays targets for broadcast-legal saturations of red (R), magenta (Mg), blue (B), cyan (Cy), green (G), and yellow (Yl). Individual colors in your video signal are displayed as dots in the vectorscope. A dots distance from the center of the scope represents its saturation, and the angle of the line from the dot to the center of the scope represents its hue. For example, if an image has a blue cast, the distribution of dots in the vectorscope will be concentrated toward the blue portion of the color wheel. If the image includes out-of-range blue values, vectorscope display will extend beyond the blue target. You can use the vectorscope to calibrate color between scenes. Without calibration, you may see noticeable color differences between scenes from multicamera shoots. 1.From the View menu, choose Video Scopes to toggle the display of the Video Scopes window. 2.Choose Vectorscope from the drop-down list. 3.Position the cursor in the frame you want to analyze. If the Update Scopes While Playing button ( ) is selected, you can monitor your video during playback. 4.The vectorscope monitor displays the chrominance of the video signal: FrameVectorscope display of frame

Use the histogram before rendering your project to find and correct out-of-range values that could cause problems on the destination playback device. The bar graph plots the number of pixels that exist for each color intensity. For example, when using the Blue setting, the vertical axis represents the number of pixels, and the horizontal axis represents the RGB color range from 0,0,0 to 0,0,255. To get acquainted with the histogram, use an external monitor to preview your video and watch the video output and histogram as you use plug-ins to modify the colors. 1.From the View menu, choose Video Scopes to toggle the display of the Video Scopes window. 2.Choose Histogram from the drop-down list. 3.Choose a histogram type from the menu: Luminance: charts the luminance or brightness of colors in your video. Red: charts the red tones in your video. Green: charts the green tones in your video. Blue: charts the blue tones in your video. Alpha: charts the alpha channel (transparency) in your video. Luminance/R/G/B: stacks luminance and RGB charts. 4.Position the cursor in the frame you want to analyze. If the Update Scopes While Playing button ( ) is selected, you can monitor your video during playback. 5.Use the histogram to evaluate the colors in your video. The Mean value indicates the average intensity of all pixels in the graph, and the Standard Deviation value indicates the average percentage by which pixels in the graph vary from the Mean value.

264 PREVIEWING AND ANALYZING VIDEOCHP. 15 Adjusting video scope settings Click the Settings button ( ) in the Video Scopes window to set your display options. These options adjust the display of data in the Video Scopes window and have no effect on your data. 7. 5 I R E s e t u p If your video hardware will add a 7.5 IRE setup, you can configure the Video Scopes window so the display will be consistent with an external scope connected to a device that adds 7.5 IRE setup. NTSC video in the United States adds 7.5 IRE setup to convert black to 7.5 IRE. Consumer video hardware typically does not add 7.5 IRE setup, and most professional hardware allows you to turn 7.5 IRE setup on or off. PAL video and NTSC video in Japan do not add setup. Refer to your video hardware documentation to determine whether your hardware adds 7.5 IRE setup. 1.Click the Settings button ( ) in the Video Scopes window. 2.Select the 7. 5 I R E Setup check box in the Video Scopes Settings dialog. Black will be displayed as 7.5 in the waveform monitor. If your video hardware does not add 7.5 setup, clear the check box. Studio RGB display RGB values on your computer can range from 0 to 255. Studio RGB values range from 16 to 235. If you want to limit the display of the Video Scopes window to studio RGB standards, perform the following steps: 1.Click the Settings button ( ) in the Video Scopes window. 2.Select the Studio RGB (16 to 235) check box in the Video Scopes Settings dialog. Whether you need to use the Studio RGB (16 to 235) setting depends on the DV codec you will use to render your video before printing to tape. Suggested settings follow. Refer to the codecs documentation to determine whether the Studio RGB (16 to 235) check box should be selected. If the Use Microsoft DV codec check box is selected on the General tab of the Preferences dialog, the Microsoft DV codec will be used. If the Ignore third-party DV codecs check box is selected and the Use Microsoft DV codec check box is cleared on the General tab of the Preferences dialog, the Sony Pictures Digital DV codec will be used. You can render using a third-party DV codec by choosing a specific codec from the Video format drop-down list on the Video tab of the Custom Template dialog.

266 PREVIEWING AND ANALYZING VIDEOCHP. 15 Using an external monitor You can feed video directly from the timeline to a television monitor. With this feature, you can make your final editing decisions on a broadcast monitor (which differs significantly from a computer monitor) before printing the project to tape. To use an external monitor, you must have: OHCI-compliant IEEE-1394 DV card DV camcorder or DV-to-analog converter box While configuring your computer for DV external monitor previewing is not difficult, the setup may require some troubleshooting. The Vegas forum is a good resource for peer-to-peer system troubleshooting: http://mediasoftware.sonypictures.com/forums Setting up an external monitor The diagram below shows the preferred setup for sending video from the timeline to an external television monitor. The video conforms to DV format and feeds through the 1394 card to the DV device (camcorder or DV-to- analog media converter). The DV device sends analog output to the television monitor. Note: The DV device must support pass-through in order to use an external monitor. Some PAL camcorders do not support this feature. Previewing audio External monitor previewing differs in one respect from printing to tape from the timeline: no audio is sent through the 1394 card. As shown in the illustration above, the audio is routed to the sound card and then on to the mixer (if present) and speakers. This allows you to mix your audio on better speakers than are typically found in television monitors. Before printing to tape, you may wish to preview the audio through the television monitor speakers to ensure a good TV mix. You can use the print-to-tape feature to send the full video and audio to the external monitor. Follow the steps for printing to tape from the timeline (pg. 284) but do not set the camcorder to record. Both the video and audio are sent through the 1394 card to the external monitor.

CHP. 15PREVIEWING AND ANALYZING VIDEO 267 Optimizing preview quality Keep in mind that complex effects and/or transitions may not play back in real time from the timeline. What effects can and cannot be played back depends on the speed of your computer. You may want to prerender more complex portions of a project. For more information, see Prerendering video on page 255. Note: The compression settings used to create the prerendered video must be identical to your captured files for timeline playback to work. Configuring an external monitor 1.Connect your camera to the IEEE-1394 card and turn it on in VTR mode. 2.Run Vegas software. 3.From the Options menu, choose Preferences. 4.Click the Video Device tab. 5.Select your device from the Device list (e.g., OHCI Compliant IEEE-1394/DV). The output is directed to the camcorder through the IEEE-1394 card. You can preview this output on the camcorder’s LCD screen or connect the camera to a television monitor to preview the output there. Once you have verified that the external monitor settings are working correctly, you can use it to preview your project. Verifying the external monitor configuration 1.Click the Preview on External Monitor button ( ) on the Video Preview window. 2.Open a properly formatted AVI (e.g., a DV AVI) file in the Trimmer window. 3.Click the Play button ( ) in the Trimmer window to test the output. This can be a complex hardware issue. You can find more detailed information at the Sony Pictures Digital Media Software and Services Web site (http://www.sony.com/mediasoftware).
