S_FilmEffectProvides a physically accurate model of film exposure and processing to make your video footage look like it was shot on particular film stocks. It can remove field artifacts, perform color correction for specific film types, add film grain, and apply glow or soft focus effects. The color correction and grain can be selectively disabled using the Scale CC and Grain Amp parameters.In the Sapphire Stylize category.

-
Scale CC:
Default:
1,
Range:
0 or greater.
Scales the amount of color correction performed due to the film types, gamma values, and exposure values. Set to 0 to disable color correction. If you increase this above 1.0 it exaggerates the color correction, which normally increases the contrast.
-
Input Gamma:
Default:
2.2,
Range:
0.1 to 10.
The gamma that your original clip was shot for. For video this is normally 2.2; for synthetic computer graphics it may be less.
-
Output Gamma:

-
Print Lights Green:
Default:
25,
Range:
0 or greater.
Adjusts the green exposure of the print film, in printer light points. 1 light point is 1/12 stop. Increase to over-expose green and give a more magenta result.
-
Print Lights Blue:
Default:
25,
Range:
0 or greater.
Adjusts the blue exposure of the print film, in printer light points. 1 light point is 1/12 stop. Increase to over-expose blue and give a more yellow result.
-
Offset Darks:
Default:
0,
Range:
any.
Adds this gray value to the darker regions of the final result after the other color correction, glow, and grain are applied. This can be negative to increase contrast. (This parameter is not affected by Scale CC.)
-
Scale Brights:
Default:
1,
Range:
0 or greater.
Scales the bright areas of the final result after the other color correction, glow, and grain are applied. (This parameter is not affected by Scale CC.)
Glow Parameters:
-
Glow Brightness:
Default:
0,
Range:
0 or greater.
If positive, the image is combined with a blurred version of itself to give a glowing look. Increase for a brighter glow.
-
Glow Soft Focus:
Default:
0,
Range:
0 to 1.
If positive, the image is mixed with a blurred version of itself to give a soft focus look. The effect of this parameter is similar to Glow Brightness, but this does not brighten the overall result. Increase this to mix in more of the blurred version and less of the original. If this is 1 and Glow Brightness is 0 you will get only the blurred version.
-
Glow Width:
Default:
0.5,
Range:
any.
The width of the blur used by the glow and/or soft focus.
-

Range:
0 or greater.
The relative glow width for the green channel.
-
Glow Width Blue:
Default:
1,
Range:
0 or greater.
The relative glow width for the blue channel.
Grain Parameters:
-
Grain Amp:
Default:
1,
Range:
0 to 25.
Scales the amplitude of the film grain that is added to the result. Set this to 0 to disable all grain.
-
Grain Amp Red:
Default:
0.9,
Range:
0 or greater.
Scales the red grain amplitude.
-
Grain Amp Green:
Default:
1,
Range:
0 or greater.
Scales the green grain amplitude.
-
Grain Amp Blue:
Default:
1.6,
Range:
0 or greater.
Scales the blue grain amplitude. Note that grain is added and subtracted from the image, so for example, increasing Grain Amp Blue will amplify both the blue and yellow speckles.
-
Grain Amp Darks:
Default:
0.2,
Range:
0 or greater.
The relative amount of grain applied to the darkest regions of the image, per channel. This defaults to less than 1.0 because dark areas usually have less grain than midtones.
-
Grain Amp Brights:
Default:
0,
Range:
0 or greater.
The relative amount of grain applied to the brightest regions of the image, per channel. This defaults to zero because bright areas usually have less grain than midtones. Note that highly saturated colors can be affected by both Grain Amp Darks and Grain Amp Brights because they are dark in some color channels and bright in others.
-
Midtone Pos Red:
Default:
0.5,
Range:
0 to 1.
The position of the midtones in the red channel that will normally receive the maximum amount of grain. The red grain amplitude is interpolated from Grain Amp Darks at black, up to 1.0 at this midtone position, then down to Grain Amp Brights at white. This whole curve is then scaled by the Grain Amp Red parameter.
-
Midtone Pos Green:
Default:
0.5,
Range:
0 to 1.
The position of the midtones in the green channel that will normally receive the maximum amount of grain. The green grain amplitude is interpolated from Grain Amp Darks at black, up to 1.0 at this midtone position, then down to Grain Amp Brights at white. This whole curve is then scaled by the Grain Amp Green parameter.
-
Midtone Pos Blue:
Default:
0.5,
Range:
0 to 1.
The position of the midtones in the blue channel that will normally receive the maximum amount of grain. The blue grain amplitude is interpolated from Grain Amp Darks at black, up to 1.0 at this midtone position, then down to Grain Amp Brights at white. This whole curve is then scaled by the Grain Amp Blue parameter.
-
Grain Blur:
Default:
0,
Range:
any.
The grain is smoothed by this amount. Increase for coarser grain.
-
Grain Blur Red:
Default:
1,
Range:
0 or greater.
The relative blur amount for the red grain.
-
Grain Blur Green:
Default:
0.9,
Range:
0 or greater.
The relative blur amount for the green grain.
-
Grain Blur Blue:
Default:
1.2,
Range:
0 or greater.
The relative blur amount for the blue grain.
-
Grain Mono:
Check-box, Default:
off.
When enabled, the same grain pattern is used for the red, green, and blue channels. To make truly monochrome grain you should also set Grain Amp Red/Green/Blue equal to each other, make sure Midtone Pos Red/Green/Blue are equal, and if GrainBlur is positive also set Grain Blur Red/Green/Blue equal
-
Grain Hold:
Popup menu, Default: Frame
.
Indicates how often a new grain pattern should be generated. You will probably only notice a difference between these options if Grain Blur is positive to make the grain size larger than one pixel.
-
Field:
holds the grain pattern for one field.
- Frame: holds the grain pattern for one frame (2 fields).
- 3:2 Pulldown at 0: holds the grain in a 3:2 pulldown pattern with the first pulldown frame at 0. These options are appropriate if your clip was created at 24 fps but is now in 30 fps pulldown form. They will not make sense if your clip is 24P. A 3:2 pulldown pattern repeats every 5 frames, so if frame 1:00:23 is the first frame with field artifacts after three normal frames, then you should specify 3 as the first pulldown frame.
- 3:2 Pulldown at 1: holds the grain in a 3:2 pulldown pattern with the first pulldown frame at 1.
- 3:2 Pulldown at 2: holds the grain in a 3:2 pulldown pattern with the first pulldown frame at 2.
- 3:2 Pulldown at 3: holds the grain in a 3:2 pulldown pattern with the first pulldown frame at 3.
- 3:2 Pulldown at 4: holds the grain in a 3:2 pulldown pattern with the first pulldown frame at 4.
- Frame: holds the grain pattern for one frame (2 fields).
-
Field:
holds the grain pattern for one field.
-
Grain Seed:
Default:
0.123,
Range:
0 or greater.
Initializes the random number generator for the grain generation. The actual seed value is not significant, but different seeds give different grain patterns and the same value should give a repeatable pattern.
Vignette Parameters:
-
Vignette Darkness:
Default:
0,
Range:
0 to 1.
Vignetting is darkening of the image towards the corners and sides of the image. This parameter controls how much the outer corners of the screen should be darkened (vignetted). 0 gives no vignetting, 1 gives maximum darkening.
-
Vignette Radius:
Default:
1,
Range:
0 or greater.
Distance from the center to apply the vignette.
-
Vignette Edge Softness:
Default:
0.5,
Range:
0 or greater.
The width of the vignette's soft edge. Larger values give softer, less visible edges.
-
Vignette Rel Height:
Default:
0.75,
Range:
0.1 or greater.
Controls the aspect ratio of the vignette ellipse. This should normally be set to the aspect ratio of the image, e.g. .75 for NTSC.
Other Parameters:
-
Fields:
Popup menu, Default: As Is
.
Allows removing field artifacts from the input clip. This is useful if you want the clip to look like it was shot on frames instead of fields. You can show a single field, merge the two together, or simulate a 3:2 pulldown stutter pattern. This parameter requires AVX2 for all its options to work. It is not included on non-DS AVX1 hosts because alternate field access is not supported. On DS, you need to process on frames instead of fields for this to work, and the 3:2 stutter options are not available.
-
As Is:
leaves the fields unchanged.
- Keep Lower Only: shows the lower field only, removes the upper field.
- Keep Upper Only: shows the upper field only, removes the lower field.
- Merge Fields: blends both fields together to remove interlacing artifacts.
- 3:2 Stutter at 0: Simulates a temporal stutter effect as if the clip had been transferred from 24P to NSTC video using 3:2 pulldown, with the first pulldown frame at 0. If you are using this option with non-zero Grain Blur, you may want to also set Grain Hold to the corresponding value.
- 3:2 Stutter at 1: Simulates a 3:2 pulldown effect with the first pulldown frame at 1.
- 3:2 Stutter at 2: Simulates a 3:2 pulldown effect with the first pulldown frame at 2.
- 3:2 Stutter at 3: Simulates a 3:2 pulldown effect with the first pulldown frame at 3.
- 3:2 Stutter at 4: Simulates a 3:2 pulldown effect with the first pulldown frame at 4.
- Keep Lower Only: shows the lower field only, removes the upper field.
-
As Is:
leaves the fields unchanged.
-
Field Dominance:
Popup menu, Default: Lower First
.
Specifies which field should come first in time when simulating 3:2 pulldown patterns. This is only used if a 3:2 stutter option is selected in the Fields and/or the Grain Hold options.
-
Lower First:
the lower field is first in time.
- Upper First: the upper field is first in time.
- Upper First: the upper field is first in time.
-
Lower First:
the lower field is first in time.
-
Mask Use:
Popup menu, Default: Luma
.
Determines how the Mask input channels are used to make a monochrome mask.
-
Luma:
the luminance of the RGB channels is used.
- Alpha: only the Alpha channel is used, or if there is no valid Alpha channel the Red channel is used.
- Alpha: only the Alpha channel is used, or if there is no valid Alpha channel the Red channel is used.
-
Luma:
the luminance of the RGB channels is used.
-
Blur Mask:
Default:
0.05,
Range:
any.
Blurs the Mask input by this amount before using. This can provide a smoother transition between the masked and unmasked areas. It has no effect unless the Mask input is provided.
-
Invert Mask:
Check-box, Default:
off.
If on, inverts the mask input so the effect is applied to areas where the Mask is black instead of white. This has no effect unless the Mask input is provided.
