  • Page 10: Step 2 - Set Up To Color Bars

    This important step ensures that what you see in DV Rack at the shoot is what you get later in production. While you’re at the shoot, we recommend setting up to Color Bars whenever lighting around your computer changes significantly.

    DV Rack’s two Zebras are useful for making these kinds of creative adjustments as you shoot.
  • Page 29: Framing Your Shot

    NOTE: By default, DV Rack sets the Zebra 1 threshold to highlight areas that are at 100% brightness or higher. In some cases, video brightness can reach up to 110% but in most circumstances, a 100% setting is sufficient. Using Zebra to identify light areas: Click the Menu button.

    Dark values are displayed on the left side of the scope, and white values are displayed on the right. This is similar to the way graphics software like Adobe® PhotoShop® represents brightness. If there’s a peak on the left side of the scope, that means the video is mostly dark.

  • Page 36: The Spectra 60

    The DV Rack Spectra 60 enables you to digitally monitor and evaluate your video with pixel-accurate chroma and luminance samples. It is different than traditional analog analysis tools as it allows you to monitor any pixel in an image whereas traditional scopes provide only scanline or full screen information.

    Also, because the clipboard can only hold one object at a time, if you copy other items from DV Rack or any other application onto the clipboard before pasting the still into an application, the still will be overwritten.

    You may not see the flash while you record but DV Rack will catch it and display it as a video clipping alert in your DVR. You set the allowable luma level, sample area and event duration thresholds and video Clip Alerts tell you when your video quality exceeds all three threshold settings.

  • Page 43: Improving Clip And Scene Continuity

    Even if you just break for lunch, important aspects of your clips can change. Avoid continuity problems by using the DV Rack split screen feature. Using the Clip List to Check Video Continuity Sometimes an instant full-screen cut between two pre-recorded scenes is a better way to compare framing or catch continuity problems.
  • Page 44: Maintaining Consistent Color And Brightness Using A Green Screen

    This saves time in the edit suite by allowing you to use the same keyer settings for all clips. Another valuable application for DV Rack when shooting chroma key is to use the Spectra 60 to detect background color spill onto your foreground subject. Spill is the subtle color tinting on your subject from light bouncing off the floor back onto the subject.
  • Page 45: Videography Basics

    In these short recaps, we hope to give you enough essentials to understand how you can use some of the DV Rack components to improve your video and audio quality. For example, we believe that you can do a better job of using Zebra to adjust exposure and lighting if you have some idea of how Zebra patterns work.

    In this case, you should carefully review the shot in the DV Rack digital recorder (using the freeze, zoom and Spectra 60 func- tions if necessary) to ensure that the camera's automatic white balance function correctly tracked the changing scene.
  • Page 48: Audio Clipping

    “pop” may not clip at all but will still become an undesirable artifact in your audio signal. This is why DV Rack also has a pop detector designed to identify sudden surges in sound that don't clip but are likely to result in unpleasant, and possibly, unusable audio.
  • Page 49: Achieving Good Technical And Aesthetic Framing

    As you can imagine, this is a hit or miss process. Most professionals prefer to monitor and adjust their audio levels manually except in certain circumstances where this is not possible. DV Rack takes a great deal of the complexity and risk out of recording audio in manual mode.
  • Page 50: Technical Framing

    Framing your tal- ent too tightly can give your audience an unwanted sense of apprehension or claustrophobia. The Rule of Thirds Use the DV Rack framing Grid to help you keep your shots well framed. See The Settings Menu to learn how to turn on the Grid.
  • Page 51: Keeping Your Shot In Frame While Shooting

    Happily, you won’t need to take a felt pen to your computer screen. DV Rack has a Grid feature which superimposes lines on your picture to help you frame while shooting. See Using the Field Monitor Grid to frame your shot.
  • Page 52 “crisp” instead of washed out. This is one of the big advantages of DV Rack. Tools like the Waveform Monitor, Spectra 60 and SureShot let you maxi- mize your signal to fill the available dynamic range. This can only be done at the time you are shooting because the expanded dynamic range must be captured on location by adjusting your camera, lights and scene composition.
