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.

Count the number of horizontal divisions from one high point to the next (i.e. peak to peak) of your oscillating signal. Next, you’ll multiply the number of horizontal divisions by the time/division to find the signal’s period. You can calculate the signal’s frequency with this equation: frequency=1/period.

The “Time/Div.” wheel determines, how long the electronic beam that draws the curve takes for moving from the left to the right edge of a division. The wheel controls the “time scale”. A “division” is one square on the screen of the oscilloscope.

The YC Waveform displays luminance information as a green waveform. Bright objects produce a waveform pattern (bright green areas) near the top of the graph; darker objects produce a waveform toward the bottom.

Your scope should confirm your intuition with clusters of green dots peaking at higher levels than red or blue. To balance your highlights, simply navigate to the Curves Panel in Lumetri and adjust the top point of the green curve to bring the peaking greens into balance with the reds and blues.

Luma shows the levels of brightness from an input source. RGB Parade will monitor the level of Red, Green and Blue from an input source. The Luma or Luminance Waveform is a great way to visualize the dynamic range of your image, allowing you to protect exposure of both your highlights and shadow detail.

To open the Lumetri Scopes panel, you can go to Window > Lumetri Scopes, or you can choose the color workspace (either by selecting the color tab or by going to Window > Workspaces > Color), which will open the Lumetri Color panel and the Lumetri Scopes panel.

Learn to Use Your Scopes! – Easy Colour Correction

• The colour correction and grading process is a strange but exciting combination of technical adjustments and artistic expression.
• In DaVinci Resolve, the waveform scope sets up the full range of luma information in your image from left to right of the frame against a 0 – 1023 vertical scale.

Adjust color (hue and saturation) settings so that male or female hispanic skin is about 30 – 35% saturated and located directly on the skin tone line, or no more than 2° above it. Again, in this example, hue and saturation are just about perfect.

RGB Overlay: Combines waveforms for the red, green, and blue color components in one display. Red: Shows only the red color channel.

The RGB Parade is essentially three separate waveforms for each of your red, green and blue channels. Like the RGB histogram found on many DSLRs. All three waveforms should be identical. The vectorscope ignores brightness completely and only looks at the colour of your shot.

You can access the RGB Parade in Premiere Pro by clicking on the small spanner icon in the monitor window or by clicking the panel menu at the top right hand side of the panel (the icon that looks like a series of lines with a small downwards facing arrow to the left of them).

Lumetri scopes are one of the most important features in Adobe Premiere Pro. Lumetri is that color correcting feature found in Premiere Pro. At the same time, Lumetri Scopes are several graphic meters that assist in color correction.
