Note:
Attempts to produce vivid colors in an image at the expense of color accuracy. This rendering intent is suitable for images, such as
graphic logos, in which bright saturated colors are more important than the exact relationship between colors.
Compares the extreme highlight of the source color space to the extreme highlight of the destination color space and shifts
all colors accordingly. Out-of-gamut colors are shifted to the closest reproducible color in the destination color space. This rendering intent
preserves more of the original colors in an image than Perceptual. This rendering intent is used by default throughout After Effects.
Leaves colors that fall inside the destination gamut unchanged. Out-of-gamut colors are clipped. No scaling of colors to
the destination white point is performed. This intent aims to maintain color accuracy at the expense of preserving relationships between colors.
Use the Scene-ref. Profile Compensation control to determine whether each instance of the Color Profile Converter effect compensates for scene-
referred profiles:
Compensates for scene-referred profiles.
Doesn’t compensate for scene-referred profiles.
Uses the setting indicated by the project’s Compensate For Scene-referred Profiles option.
For an explanation of scene-referred profiles, see System gamma, device gamma, and the difference between scene and viewing environment.
If you open an After Effects 7 project that uses DPX Scene and DPX Theater color profiles in the Color Profile Converter effect, After
Effects CS5 does not automatically update these profiles to the new equivalent profiles (Kodak 5218/7218 Printing Density and Kodak 2383
Theater Preview). Instead, the profiles are listed as Embedded. You can convert your project by manually assigning the new profiles in After
Effects CS5. However, if the same profiles were assigned to the footage or selected in Proof Colors in After Effects 7, they are automatically
updated to the new profiles in After Effects CS5. (Proof Colors has been replaced by Output Simulation.)
On his fnord website , Brendan Bolles explains how to use the Color Profile Converter effect and film color profiles to adjust colors and perform
tone mapping to make an HDR image appear as if it were shot on motion picture film.
Grow Bounds effect
The Grow Bounds effect increases the layer size for the effect that directly follows it. This effect is most useful with layers that have Collapse
Transformations / Continuously Rasterize enabled, because they render using a buffer that’s the size of the composition. For example, if you apply
Drop Shadow to a text layer that’s partially out of the composition frame, the shadow is clipped because only the portion of the text that’s in the
composition frame casts a shadow. Applying the Grow Bounds effect before the Drop Shadow effect prevents the shadow from being cut off. The
number of pixels you specify increases the height and width of the layer buffer.
You should not need to use this effect when working with effects that work with 32-bpc color, because these effects have been updated to
automatically compensate for layer size.
This effect works with 8-bpc, 16-bpc, and 32-bpc color.
