If Preserve RGB is selected, the color values are not converted in this step. Instead, the numerical RGB color values
are preserved and are re-interpreted to be in the color space of the simulated device. One use of this simulation is to
see how a movie will look when played back on a device other than the one for which it was intended or a device that
does not perform color management.
Note: Preserve RGB is also used when simulating the combination of a capture film stock and a print film stock.
3. Colors are converted from simulated playback device's color space to your monitor's color space
converted from the presentation device color space to the color space of your computer monitor using the monitor
profile.
When you create an output simulation preset, you can choose a profile to use for each of these steps.
Even if you're using a preset output simulation, you can choose the Custom option in the View > Simulate Output
menu after selecting the preset to see a representation of which color conversions and reinterpretations are occurring
for that simulation type.
Output simulation applies only to a specific viewer (Composition, Layer, or Footage panel) and works only for
previews. Color conversions for output simulation are performed when values are sent to the display. Actual color
numbers in the project are not changed.
As with all color space conversions, simulating output decreases performance somewhat, so you may not want to
simulate output when performing tasks that require real-time interaction.
Note: Merely applying the correct profiles can't compensate for different color gamuts for different devices. For example,
common LCD monitors do not have the gamut necessary to fully simulate HDTV output.
You can press Shift+/ (on the numeric keypad) to turn display color management on or off. Turning display color
management off also turns output simulation off. Simulation settings (including No Output Simulation) are remem-
bered.

Simulate output for previews
1 Activate a Composition, Layer, or Footage panel.
Choose View > Simulate Output, and choose an output type to simulate.

Note: Output simulation relies on display color management, which is on by default. If display color management is off,
choose View > Use Display Color Management.
Display color management is on, but no conversion is performed to simulate an output type.
