Clip Resolution
Ordinarily, the resolution of a clip is entirely dependent on the resolution that was selected when that
media was shot, or rendered out of a compositing, VFX, or 3D application. Once a piece of media has
been created, the native resolution of that media cannot be changed, and to maintain the ideal amount
of sharpness for that clip, you need to make sure that whatever transforms you apply to resize a clip
zoom into that clip no more than 10-20% over its native resolution (if even that), otherwise the image
will visibly soften.
However, DaVinci Resolve provides advanced Super Scale image processing in the Clip Attributes of
every video and image clip, that make it possible to resize clips beyond their native resolution while
maintaining the perceptible sharpness of a clip that’s still within it’s native resolution. This is an illusion,
but it’s a convincing one.
The DaVinci Resolve Sizing Pipeline
This section discusses the various sizing controls that are available in DaVinci Resolve, and how they
work together.
“Super Scale” High Quality Upscaling (Studio Version Only)
For instances when you need higher-quality upscaling than the standard Resize Filters allow, you can
now enable one of three “Super Scale” options in the Video panel of the Clip Attributes window for
one or more selected clips. Unlike using one of the numerous scaling options in the Edit, Fusion, or
Color pages, Super Scale actually increases the source resolution of the clip being processed, which
means that clip will have more pixels than it did before and will be more processor-intensive to work
with than before, unless you optimize the clip (which bakes in the Super Scale effect into the optimized
media) or cache the clip in some way.
Super Scale options in the Video panel of the Clip Attributes
The Super Scale drop-down menu provides three options of 2x, 3x, and 4x, as well as Sharpness and
Noise Reduction options to tune the quality of the scaled result. Note that all of the Super Scale
parameters are in fixed increments; you cannot apply Super Scale in variable amounts. Selecting one
of these options enables DaVinci Resolve to use advanced algorithms to improve the appearance of
image detail when enlarging clips by a significant amount, such as when editing SD archival media into
a UHD timeline, or when you find it necessary to enlarge a clip past its native resolution in order to
create a closeup.
You may find that, depending on the source media you’re working with, setting Sharpness to Medium
yields a relatively subtle result that can be hard to notice, but setting Sharpness to high should be
immediately more preferable, while also sharpening grain and noise in the image to an undesirable
extent at the default settings. However, while raising Noise Reduction will ameliorate this effect, it will
also diminish the gains you obtained by raising Sharpness. In these cases, it’s worth experimenting
with keeping Sharpness at Low or Medium so that Super Scale sharpens all aspects of a clip, but then
using the Noise Reduction tools of the Color page (with their additional ability to be fine-tuned) to
diminish the unwanted noise.
