SpeedGrade provides various tools, like the following, to analyze your image:
- RGB Parade
- Luma Waveform
These tools are now grouped together and available from the Analysis Tools panel.
To display the Analysis Tools panel, use the keyboard shortcut A, or click the arrow on the upper-left Monitor panel. You can adjust the size of the Analysis Tools panel using the drag handles.
Use the context menu to choose which video scope you want to view.
Histogram shows RGB values. The minimum Luma values per channel are displayed as numerical feedback at the bottom. Maximum values are displayed at the top. Two horizontal lines indicate the output range. The default range is set to CIN code values (95 - 685).
The Vectorscope displays the video’s chrominance information in a a circular chart. Saturation is measured from the center of the chart outward.
Vectorscopes work in YUV and HLS (Hue, Lightness, Saturation) modes. The YUV Vectorscope uses the more familiar YUV color space including color targets to display the pixel distribution in your images more intuitively. The YUV vectorscope is the default option.
RGB Parade scope displays separate waveforms for the red, green, and blue components of an image. The waveforms are displayed side by side, making it easy to compare the relative levels of reds, greens, and blues in an image, and make adjustments as required. The RGB Parade scope also makes it easy to spot color casts in your image.
The Luma Waveform scope displays a representation of the luminance of your images, similar to how it is displayed in Premiere Pro.
High luma levels appear as spikes on the waveform, and low luma levels appear as dips. This scope lets you quickly identify highlights and shadows in your image, helping you achieve precise black-and-white balancing.

Use channel views to check specific color channels. For example, you can use it to check for compression artifacts or noise in the RGB channels.
To see a channel on the Monitor, follow these steps:
- Select the Timeline tab, and then select View.
- Select a channel from the Channel View menu under Display Options.
For example, if your image includes an alpha channel, select Alpha Channel to view on the Monitor. To switch back to normal view, select the channel view as Normal View.
