S_FilmEffect Provides a physically accurate model of film exposure and processing to make your video footage look like it was shot on film. 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 effects submenu. Inputs: Source:  The current layer.   The clip to be processed.

Parameters:

Neg Film:   Popup menu,  Default: Kodak_5245.
Selects the negative film stock.

None:  Ignore any effect of negative film. This is not normally useful unless you also select None for the print film to disable both.

Kodak_5245:  Eastman EXR 50D, low speed, daylight balanced, very fine grain.

Kodak_5246:  Kodak VISION 250D, higher contrast, medium speed, daylight balanced, fine grain.

Kodak_5248:  Eastman EXR 100T, medium speed, tungsten light balanced, very fine grain.

Kodak_5274:  Kodak VISION 200T, medium speed, tungsten light balanced, fine grain.

Kodak_2395:  Kodak VISION Color Teleprint Film, low contrast.

Kodak_5386:  Eastman EXR Color Print Film (discontinued by Kodak, replaced by 2383).

Blur Input:   Default: 0,  Range: 0 or greater.
The input is smoothed by this amount. This can be used to remove video noise or compression artifacts before processing.

Scale CC:   Default: 1,  Range: 0 to 5.
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:   Default: 2.2,  Range: 0.1 to 10.
The intended viewing gamma of the output.

Neg Exposure:   Default: 0,  Range: any.
Adjusts the simulated exposure of the negative film, in stops. Increase for over-exposed and brighter.

Print Exposure:   Default: 0,  Range: any.
Adjusts the simulated exposure of the print film, in stops. Increase for over-exposed and darker.

Print Lights Red:   Default: 25,  Range: 0 to 50.
Adjusts the red exposure of the print film, in printer light points. 1 light point is 1/12 stop. Increase to over-expose red and give a more cyan result.

Print Lights Green:   Default: 25,  Range: 0 to 50.
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 to 50.
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.

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.)

Offset Darks:   Default: 0,  Range: -8 to 2.
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.)

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: 20,  Range: 0 or greater.
The width of the blur used by the glow and/or soft focus.

Glow Width Red:   Default: 1,  Range: 0 or greater.
The relative glow width for the red channel.

Glow Width Green:   Default: 1,  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 Amp:   Default: 1,  Range: 0 or greater.
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 to 2.
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 to 2.
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: 0 or greater.
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 Stutter 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 Stutter at 1:  holds the grain in a 3:2 pulldown pattern with the first pulldown frame at 1.

3:2 Stutter at 2:  holds the grain in a 3:2 pulldown pattern with the first pulldown frame at 2.

3:2 Stutter at 3:  holds the grain in a 3:2 pulldown pattern with the first pulldown frame at 3.

3:2 Stutter at 4:  holds the grain in a 3:2 pulldown pattern with the first pulldown frame at 4.

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.

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.

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.

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.
