Quality Control
Lastly, it’s important to keep in mind that, for all the creative possibilities that DaVinci Resolve
affords, it’s still important that the final deliverables that you give to your client has appropriate
signal levels relative to their requirements. In particular, programs destined for broadcast have
specific outer boundaries of luma and chroma that you must not exceed, or you’ll risk having a
show rejected for QC (quality control) violations.
However, even if you’re not delivering a show for broadcast, it’s important to be aware of the
mathematical limitations of a digital video signal to make sure you’re not clipping or crushing
image detail through overzealous adjustments that you may, in fact, want to preserve.
For example, if you take a look at the next two images, you can see the perils of overzealous
adjustments when compared to a clip that, while graded creatively, has been adjusted with
respect to the mathematical boundaries of image data.

Here, too, DaVinci Resolve provides tools designed to help you exercise control over the
fine-tuning of the image. A Video Scopes window provides the standard Waveform, Parade,
Vectorscope, and Histograms that are used to analyze your image data. These scopes let you
see the boundaries of what’s possible, and make it easy to spot subtle problems, and compare
the characteristics of one image to another.
