Sometimes shots in a video edit just don’t match. They could be too bright, too dark, or the wrong color entirely. Blender’s Video Sequence Editor (or VSE) can be used to balance and fix differing colors and brightness levels between shots. Using Blender’s Scopes tools you can efficiently discover what is wrong and how to fix it. In this series of tutorials we will use Adjustment Layer effect strips to create multiple color corrections that are easily reusable.
We will look at 2 typical post-production problems: 1. In the first lesson of the tutorial we will learn to read the Waveform, Vectorscope and Histogram using a simple gradient. Then we will explore their function with a more complicated image. We’ll look at the differences between "Color Correction" and "Color Grading". 2. For the second lesson we work with mismatched shots of a human face, that has been lit very differently. Blender’s Adjustment Strips allow us to add strip modifiers like Hue Correct and Color Balance while we watch the scopes for accurate feedback. 3. Finally, we’ll load up some exterior shots that were filmed at different times of day. Using The VSE waveform scope we will check the image for clipping or loss of data in the black or white region and try to match the brightness and contrast of the other shots. Then we will use the Vectorscope to look for color bias or incorrect tint and adjust appropriately.
