GPU Acceleration
Processing
with the Graphics Processing Unit (GPU) is available for certain features
and is faster than processing with the Central Processing Unit (CPU).
Support for GPU acceleration
depends on the version of the NVIDIA graphic card that is installed
on your system. The following configurations are supported for GPU
acceleration.
| Configuration |
Feature available? |
| FX5600 |
Yes |
| FX5500 |
Yes (except Noise plugin 3.1) |
GPU acceleration is available
for the following features:
- 1D or 3D on calibration LUTs
- Animated or still repositions (including
rotations)
- Animated or still input primary grading
- Input and output primary grading with
RGB, hue and light saturation (LS) curves
- Secondary grading with RGB curves
- Secondary grading with hue curves
- Secondary black clip/reference and white
clip/reference in Linear mode
- Secondary key cleanup and shrink
- Imported mattes for secondaries
- Gamma and contrast adjustments to secondaries
in Linear mode
- Low, mid, and high adjustments to secondaries
- Input and render/output LUT
- Lustre Sparks plugins
- Blur mix
- Glow
- Noise plugin 3.1
- Printbleach
NoteA performance hit
can occur when using the Lustre Sparks plugins.
For more information
about these features, see:
GPU acceleration is also
available for certain secondary grading features with up to 12 layers
enabled. You can apply, and optionally animate, each of the following
secondary grading features and continue to use GPU acceleration:
- Primary grading inside and outside geometries,
including adjustments to overall brightness, contrast, hue, and
saturation
- Softness, Color, and Opacity slider values
for geometries, with Softer and Variable optionally enabled
- Key-in shapes based on hue, luminance,
and saturation, and refined by tolerance and softness range definition
- Key and geometry blurs
NoteA performance hit
can occur when using the geometry blur.
- Multiple point changes for geometries
For more information
about these features, see
Secondary Colour Grading.
When GPU acceleration
is enabled, the histogram, vectorscope, and waveform monitors do
not dynamically update. They retain the colour distribution of the
image before GPU was enabled.
The following parameters
cannot be accelerated by the GPU. These parameters are processed
by the CPU instead.
Lustre Sparks plugins:
- Add noise
- Blur
- Defocus
- Directional blur
- Field zoom
- Gold
- Noise plugin 2
- Noise plugin 3
- Silver
NoteIf GPU acceleration
is enabled and Lustre encounters a shot with features that cannot
be processed by the GPU, the CPU is used for the shot. The GPU button
remains enabled, but is greyed out until you navigate to the next
shot in the timeline that contains features available for GPU acceleration.
To enable GPU acceleration:
- Complete one of the following:
A GPU flag appears in
the upper-right section of the Player.
NoteGPU acceleration
only works in progressive scan mode. Before you render a project,
you need to switch the scan type to interlaced (located in the Setup
> Grade menu).
To disable GPU acceleration:
- Complete one of the following:
- Click GPU.
- Press Shift+Y.
GPU acceleration is disabled.
