Film-to-tape transfer, color correction and other production activitiesīecause each person’s eyes see the world differently, scopes are useful for objectively evaluating a shot.Diagnosing and troubleshooting video equipment.“Lining up” multi-camera setups (to ensure the same shot under the same conditions will produce the same results).Practically speaking, waveform and vectorscope monitoring is commonly used in a video environment for the purposes of: A vectorscope maps a video’s color information onto a circular chart. In simplified terms, a waveform monitor displays the brightness (or “luminance”) of a shot over time, while vectorscopes are used to measure the color information in a video image, such as hue and saturation. An electrocardiogram (EKG) waveform Video scopes for live productionīased on oscilloscope technology came two very useful scopes for video: the waveform monitor and the vectorscope. Oscilloscopes are used in the sciences, medicine, engineering, automotive and telecommunications industries.įor example, I’ve you’ve ever been to a hospital or medical clinic for an electrocardiogram–the process of recording the electrical activity of the heart over a period of time using electrodes placed on the skin–you’ve actually experienced a special type of oscilloscope firsthand. The observed waveform can be analyzed for properties like: amplitude, frequency, rise time, time interval, distortion etc. The resulting plot is what is known as a waveform – the shape and form of a signal in the shape of a wave. Modern video scopes are based on the original oscilloscope, defined as a type of electronic test instrument that allows observation of constantly varying signal voltages, usually as a two-dimensional plot of one or more signals over a function of time.
#Scopebox not reliable portable
But for those who aren’t – video scopes are powerful tools for perfecting your video productions in both live and post-production settings, especially when combined with portable capture devices, such as Epiphan’s AV.io family of versatile and easy to use video grabbers. If your line of work involves monitoring and/or editing video images, you’re already likely familiar with the concept of a scope.
