Waveform

The Waveform scope provides a view of the luminance in the video signal. The vertical axis corresponds to luminance while the horizontal axis matches the horizontal axis of the video source.

Controls

Mode

The Mode dropdown allows you to choose the method ScopeBox uses to render your scope. Each mode offers you different information:

Weighted mode looks more like a traditional raster scope and expresses the number of pixels at a given value by varying the brightness.

Mono displays every data point at full intensity, which can be useful in ensuring complete legality. With weighted views it is possible to miss a small pixel region that is out of range.

Colorize replaces the traditional monochrome tone in a scope with the actual color that it represents. For example, if someone is wearing a bright red shirt, there will be a bright red streak where the scope renders those pixels.

Zoom Blacks

Often colorists want to get a detailed look at the darkest parts of a signal. The "Zoom Blacks" slider magnifies just the lower values of the signal.

Filter

The Filter dropdown allows you to select between the two commonly found filter types found on hardware waveform monitors - Luma and Chroma. Luma is the default, causing the waveform to display only the luminance (Y) channel of your video. Chroma will display only the chrominance (C) channel of your video.

Instantaneous Envelopes

Instantaneous Envelopes help ensure that you don't miss any data within your waveform monitor, even when it's just a single pixel. Checking the box will cause two bounding lines to be added to your trace, one showing the maximum values for your waveform, and one showing the minimum values for each vertical line.

Peak Envelopes

Peak envelopes show the maximum and minimum values for your waveform over time. This allows you to look away from your scopes, and still know whether you exceeded a target threshold. The reset button will clear the peak values.

Scale

There are five different Scale options available for measuring your waveform. These are IRE (the traditional scale for a waveform monitor), 8 bit, 10 bit and mV (millivolt). The 8 bit and 10 bit options allow you to measure your waveform according to the actual sample values in the signal. Millivolt allows you to compare against the signal shown by a traditional hardware waveform monitor or oscilloscope. ST2084 is the Dolby PQ Standard scale.
