The Case for Color Correction…And How A Tektronix Waveform Monitor Can Help


Many of the technical adjustments that are made to improve video quality in the post-production phase are things most people don’t notice – if they’re done right. Take color correction, for example. In a short video demonstration, hosted by Terence Curren, colorist and veteran of the film and television industry, we see how a number of production-created problems can be easily repaired in post-production with color correction. With the use of a split screen to show the before-and-after imagery, Curren shows in vivid detail the impact these changes make on the final product.

For example, when shooting in a poorly lit space or with a camera that hasn’t been properly balanced, you might end up with a scene where the talent appears too dark, bright objects appear too bright, and other distortions. Or you might need to make adjustments for two-camera shots to allow cutting back and forth between cameras without the jarring effects created by mismatched camera set-ups. Color correction also helps fine-tune color balance when a single scene moves from indoor lighting to sunlight, which casts a decidedly blue light.

Tektronix waveform monitors – or scopes as they are called in the industry – play a critical role in the color correction process. As analytical tools, scopes provide precise information that guides the colorist in fixing color correction problems, while also providing a fixed, objective reference to ensure consistency. Waveform monitors also help colorists verify that the luma and chroma signals fall within technical limits supported by broadcaster and cable service providers.
