Automatically cache Fusion Effects in User Mode: If you’ve created effects for a
clip in the Fusion page and you find that your workstation does not have adequate
performance to play that clip in real time, you can force these categories of effects to
be automatically included in the Sequence Cache and cached when you’re using the
User Mode of caching.
Working Folders
Two fields let you specify to which folders cache and gallery files are written.
Cache files location: All render cache files that you create are saved in the directory
path specified by this field. This path defaults to a hidden “CacheClip” directory
that’s created at the location of the first Media Storage Volume you specify in the
DaVinci Resolve Preferences window.
Gallery stills location: By default, all stills you save are saved in the DPX format, and
are placed in the directory path specified by this field. This path defaults to a hidden
.gallery” directory that’s created at the location of the first Media Storage Volume you
specify in the DaVinci Resolve Preferences window.
NOTE: If the volume you’ve selected to use for the cache becomes
unavailable, DaVinci Resolve will warn you with a dialog.
Frame Interpolation
These settings determine the default state for all retiming and speed change effects, including
when clips are in mixed frame rate timelines.
Retime Process: This drop-down menu lets you choose a default method of processing
clips that don’t match the project frame rate in mixed frame rate timelines and clips with
speed effects (fast forward or slow motion) applied to them, throughout the project.
Since each clip in every timeline defaults to “Project Settings,” changing this setting
will change the way most mixed frame rate and speed effected clips will be processed,
except for those with custom settings selected. There are three options:
Nearest: The most processor efficient and least sophisticated method of processing;
frames are either dropped for fast motion, or duplicated for slow motion.
Frame Blend: Also processor efficient, but can produce smoother results; adjacent
duplicated frames are dissolved together to smooth out slow or fast motion effects.
This option can provide better results when Optical Flow displays unwanted artifacts.
Optical Flow: The most processor intensive, but highest quality method of speed
effect processing. Using motion estimation, new frames are generated from the
original source frames to create slow or fast motion effects. The result can be
exceptionally smooth when motion in a clip is linear. However, two moving elements
crossing in different directions or unpredictable camera movement can cause
unwanted artifacts.
Motion estimation mode: When using mixed frame rate clips in a timeline that has
Optical Flow retiming enabled, when using Optical Flow to process speed change
effects, or when using Image Stabilization or Temporal Noise Reduction controls
in the Color page, the Motion Estimation drop-down of the Master Settings (in the
Project Settings window) lets you choose options that control the trade-off between
speed and quality.
