Use the Video Tuneup Plus effect to correct exposure problems in clips. For example, if a scene is underexposed and objects aren’t clearly defined, you can adjust the overall contrast as well as the center point of contrast to bring objects out of the shadows. You can also adjust an image’s brightness, saturation, and hue while viewing results with on-screen scopes.

Steps to use Video Tuneup Plus
- Apply the Video Tuneup Plus effect to a scene in your video editor.
- To see how gamma adjustments affect the picture, either open a video scope that is built into your non-linear editor, or to view a scope in the preview, select one of the following scopes from the Video Scopes drop-down list in the Video Tuneup Plus settings.
- Vector — Shows saturation and color levels.
- Waveform — Shows luminance levels, from black or shadow levels at the bottom to white or highlight levels at the top.
- Histogram — Shows the spread and quantity of pixels, from black or shadow levels toward the left side to white or highlight levels toward the right side. This scope also separates red, green, and blue channels and shows the combination luminance of all three channels which is represented by white.
- All Three — Displays the three available video scopes while reducing your video picture to one quarter of the preview for easy viewing.
- In the Video Tuneup Plus settings, increase or decrease Contrast to adjust the overall luminance level around the contrast center. For the most impactful image, try and maximize the use of the entire luminance spectrum.
- Adjust the Contrast Center to move the center point of contrast and balance the luminance signal in the middle of the waveform. As you adjust the contrast center into negative values, highlights react more intensely than shadows when you adjust the contrast. Conversely, as you adjust the contrast center into positive values, shadows react more intensely than highlights when you adjust the contrast.
Tip: You may need to adjust the Contrast and Contrast Center several times to achieve the desired balance.
- Adjust the following settings as needed.
- Brightness — Change the entire luminance spectrum without affecting the shape of the luminance curve.
- Saturation — Set the strength or intensity of the color. A greater value increases the amount of color enhancement.
- Hue — Shift the colors in the image around the color spectrum.
