Cache

The Cache is used to save preview frames in memory, so they can later be displayed much faster than if they were rendered from scratch. Cache capacity can be set in the System tab of the Preferences.

Which frames are cached can be visualized by enabling Show Cache.

Cache Settings

Panel:

Sidebar ‣ Cache ‣ Cache Settings

In this panel, you can select the preview rendering stages at which strip images should be cached. These settings apply to all strips.

Cache

• Raw

  Cache raw images right after they’re read from the drive, for faster tweaking of strip parameters at the cost of memory usage.

  Pre-processed

  Cache strip images after applying cropping, scaling, saturation and so on, for faster tweaking of effects at the cost of memory usage.

  Composite

  Cache strip images after blending with lower channels and applying effects, for faster tweaking of stacked strips at the cost of memory usage.

  Final

  Cache the final rendered frame.
