User Manual

 Scaling: Lets you choose how clips that don’t match the current project resolution
are handled on a clip-by-clip basis. The default setting is “Project Settings,” so that all
mismatched clips use the same method of being automatically resized. However, you
can also choose an individual method of automatic scaling for any clip. The options
are Crop, Fit, Fill, and Stretch; for more information see the 2D Transforms section of
Chapter 133, “Sizing and Image Stabilization.”
 Resize Filter: For clips that are being resized in any way, this setting lets you choose
the filter method used to interpolate image pixels when resizing clips. Different settings
work better for different kinds of resizing. There are four options:
–
Sharper: Usually provides the best quality in projects using clips that must be scaled
up to fill a larger frame size, or scaled down to HD resolutions.
–
Smoother: May provide higher quality for projects using clips that must be scaled
down to fit an SD resolution frame size.
–
Bicubic: While the Sharper and Smoother options are slightly higher quality, Bicubic
is still an exceptionally good resizing filter and is less processor intensive than either
of those options.
–
Bilinear: A lower quality setting that is less processor intensive. Useful for previewing
your work on a low-performance computer before rendering, when you can switch to
one of the higher quality options.
Lens Correction
The Lens Correction group (only available in Resolve Studio) has two controls that let you
correct for lens distortion in the image, or add lens distortion of your own.
 Analyze: Automatically analyzes the frame in the Timeline at the position of the
playhead for edges that are being distorted by wide angle lens. Clicking the Analyze
button moves the Distortion slider to provide an automatic correction. If you’re
analyzing a particularly challenging clip, a progress bar will appear to let you know how
long this will take.
 Distortion: Dragging this slider to the right lets you manually apply a warp to the image
that lets you straighten the bent areas of the picture that can be caused by wide angle
lenses. If you clicked the Analyze button and the result was an overcorrection, then
dragging this slider to the left lets you back off of the automatic adjustment until the
image looks correct.
Onscreen Controls for Transform,
Crop, and Dynamic Zoom
You also have the option of transforming, cropping, or adding dynamic zoom effects to clips
using the Transform/Crop/Dynamic Zoom button at the bottom left of the Timeline Viewer.
These on-screen controls can also be selected by choosing an option from the View > Viewer
Overlay submenu; these commands are not mapped to keyboard shortcuts by default, but you
can make a manual mapping if there’s a mode you find yourself using regularly. The currently
selected overlay can be toggled on and off by pressing Shift-` (Tilde), or by choosing View >
Viewer Overlay > Toggle On/Off.
