What is the difference between a waveform and a vectorscope?
The vectorscope is used to measure the color information in a video image, while the waveform displays the brightness, or luminance, of a shot. In post, they are essential for color grading video footage.
What is an audio vectorscope?
The Audio Vectorscope instrument (VSC) is used to monitor the balance of stereo mixes and it displays the changing phase relationship between a selectable channel pair in real time.
What is the purpose of a vectorscope?
A vectorscope measures the chrominance (color components) of a video signal, including hue and saturation. A vectorscope maps a video’s color information onto a circular chart. The traditional waveform monitor is useful in measuring the brightness, or luminance component, of a video signal.
What is a waveform monitor used for?
A waveform monitor is a special type of oscilloscope used in television production applications. It is typically used to measure and display the level, or voltage, of a video signal with respect to time.
How do waveforms work?
A waveform describes a wave by graphing how an air molecule is displaced, over time. These waveforms are said to be periodic because the wave they represent can be repeated to produce a constant tone. The faster the wave repeats, the higher the pitch of the sound. Different waveforms have different harmonics.
How are vectorscope and waveform monitors used in video?
Two of the most useful video scopes are the vectorscope and the waveform monitor. The vectorscope is used to measure the color information in a video image, while the waveform displays the brightness, or luminance, of a shot. Because everyones eyes see differently, scopes are useful to provide a quantitive way to evaluate a shot.
When do you need a vectoscope and waveform?
On set, color scopes, like the vectoscope and waveform, are useful for calibrating multiple cameras – ensuring greater consistency between shots. In post, they are essential for color grading video footage.
How can i Zoom in on a waveform monitor?
WFM supports zooming the waveform monitors and vectorscope for a closer look at low saturation signals, or the luma elements of the waveform. The live picture can also be zoomed in or out, and panned with the mouse. To zoom, place the mouse over the picture or scope, and roll the mouse wheel.
Which is the best waveform monitor for video installation?
The Tektronix WFM2300 Portable Video Waveform Monitor provides an ideal solution for video installation and maintenance applications with an integrated high-brightness, low-power consumption LED backlit display in a convenient portable form factor.
