  FILM EFFECTS
 

G Film Plus RT

G Film Plus RT is a special version of G Film Plus, but with the frame rate processing (the conversion to 24p etc.) removed. Final Cut Pro will not allow any kind of real time rendering on any plugin that looks at anything other than the “current” frame. This plugin, is, however, still very complex and not much real time performance can be achieved, even on a fast G5, but some is better than none at all. This filter is therefore also useful for when you have used a camera that already shoots 24p or other progressive frame rate.
Because this filter has so many controls, we will discuss it’s operation in it’s component parts:
Master Control
Chroma Blur Controls
Black and White Diffusion Controls
Temperature Controls
Saturation Controls
Tint Controls
Bleach Bypass Controls
Curve Controls
Grain Controls
Scratch Controls
Flicker Controls
Hair Controls
Dirt Controls
Weave Settings
Cropping Controls

 

Master Control
Master Control allows you to adjust the amount of the Film Effect added to the image. Master Control does not work by blending the raw and processed images together, but instead calculates a new Film Effect to create the percentage you've asked for. This allows the Master Control to add more of the effect you've just created (percentage > 100%) as well as less, although pushing it too far up towards 200% can, in some circumstances produce results that look to double back on themselves, especially if you've set your levels to an extreme position.

Notes
Master Effect Amount 0% to 200%
Adjusts all the settings of this filter together to add to or reduce the amount of the overall effect applied to the video.
Master Brightness
-1 to 1
Adjusts the brightness of the image to adjust the filter settings for the particular clip you are using. This is a gross control of brightness - finer controls are available in the Curves section below.
 
   
 
 
   
 

Chroma Blur Controls
The chroma blur effect is new in V2.5 and is useful for creating old and faded Film Effects, or the subtle colour blending you get in movies such as Sky Captain.

Control

Post Sharpen 0% to 100% Adjusts the amount of sharpening of the chroma that is applied after the chroma has been blurred.



Black and White Diffusion Controls
Diffusion is often added in camera with “Pro Mist” filters or silk stockings over the lens. This is the digital version of that effect, with controls that effect both the diffusion of highlights and shadows.

Control

Allows you to change the blending mode for effect. The default for white diffusion is “screen”.


Temperature Controls
These controls allow you to change the overall hue of an image, or to warm or cool shadows or highlights. You can also achieve similar effects in the Curves controls, but the temperature controls also allow you to leak the warmth or coolness into areas surrounding the shadows or highlights with the light pollution controls.

Control
Settings
Notes
Temperature On on
off
Turns the temperature effect on or off.
Cold / Warm Hue -100% to 100% Adjusts the hue of the entire image.
Cold / Warm Light -100% to 100% Negative values make highlights cooler, positive values make highlights warmer.
Cold / Warm Dark -100% to 100% Negative values make shadows cooler, positive values make shadows warmer.
Light Limit 0 to 254 Limits the effect to brighter and brighter regions of the image as the control is increased.
Dark Limit 0 to 254 Limits the effect to darker and darker regions of the image as the control is increased.
Light Light Pollution 0% to 100%
Allows the effect of warmer or cooler on the bright regions of the image to leak over into surrounding areas of the image.
Dark Light Pollution 0% to 100% Allows the effect of warmer or cooler on the dark regions of the image to leak over into surrounding areas of the image.


Saturation Controls
Changing the overall saturation or amount of colour in an image is a powerful tool to create a Film Effect. Sometimes, it is nice to not saturate or de-saturate the whole image, but base the amount of colour in an image on the brightness of the areas being
affected. By selecting Also De-Saturate? this becomes possible and the rest of the controls are activated. The De-Saturation Amount now controls the dark areas of the image and their saturation while the Saturation Amount controls the bright areas of the image. By selecting Invert Saturation the Saturation Amount now controls dark areas, and De-Saturation Amount the bright areas.

Control
Settings
Notes
Saturation On on
off
Turns the saturation effect on or off.
Saturation Amount -1 to 4 A value of -1 is totally de-saturated.
A value of 0 leaves the image unchanged
A value of 1 is an increase in saturation
A value of 4 is very saturated
Also Desaturate on
off
Normally, the Saturation effect applies to the entire image. With this control turned on, either dark or light areas on the image can be set to a different saturation or desaturation to the rest of the image.
De-Saturation Amount -4 to 1 A value of 1 is totally de-saturated.
A value of 0 leaves the image unchanged
A value of -1 is an increase in saturation
A value of -4 is very saturated
Invert Saturation on
off
Swaps over the effects of Saturation and De-Saturation Amounts so that they effect different tones in the image.


Tint Controls
Often coloured filters are used in camera to tint the image. This is the digital version of that effect. Gradient filters can be useful as you can set them to tint the sky, say, while leaving the rest of the image un-tinted.



Control
Settings
Notes
Tint On on

Turns the Tint effect on or off.
Tint Color A Color Picker This is the primary color used to tint the image.
Tint Color B Color Picker This is the secondary color used to tint the image.
Tint Amount 0% to 100% Adjusts the overall amount of the tint effect.
Mode Normal

Screen
Overlay
Lighten
Darken
Add
Selects the blending mode used to apply the tint effect to the image.
Tint Blending on
off
Blend the tint with the underlying image based on the image’s tonal values - can be used to make the effect more subtle.
Tint Blending Invert on
off
Blend the tint based on lighter or darker values in the underlying image.
Tint Gradient on
off
Turns the tint effect into a gradient filter.
Tint Gradient Direction -360 degrees to 360 degrees Adjust the angle of the tint gradient.
Tint Gradient Amount 0% to 100% Adjusts how strongly the tint is made into a gradient.
Tint Gamma -1 to 1 Adjust the mid-point of the gradient.



Bleach Bypass Controls
Bleach Bypass simulates the missing a stage of film processing that creates the effect of a black and white copy of the image being superimposed on top of the colour. This effect is often enhanced by using the Saturation controls (see above) to remove some of the colour from the image.


Control
Settings
Notes
Bleach Bypass On on
off
Turns the Bleach Bypass effect on or off.
Use Unprocessed on
off
Allows you to choose whether the effect works on image data before the other sections of the filter have had a chance to modify it or not. The setting of this control can produce widely different results. If you are not getting the effect you are expecting, try changing this setting.
Bleach Effect Amount 0% to 100% Increasing this will add in more and more bleach bypass effect. This can make the image dark, so carefully apply some Over Exposure below.
Over Exposure
0% to 100%
Adds in some over exposure to the image to help create the overall Bleach Bypass effect.
Bleach Sharpness 0% to 100% Bleach Bypass effects are often quite “gritty” in the way they look. By increasing the sharpness of the effect, a grittier effect can be achieved.


Curve Controls
Curve controls are the most important controls (other than the frame rate) to create a good Film Effect. And the most important individual controls are the White Curve Master and Black Curve Master. These allow you to create the classic "S" shaped curve that film is famous for. To do this, move the Black Curve Master to the left (negative values) and the White Curve Master to the right (positive values). The Red, Green and Blue controls allow the curve to be adjusted as offsets from the master curve we've just created with the Black Curve Master and White Curve Master controls. Moving both colour curve controls to the left (negative values) will reduce the effect of that colour throughout the tonal range, and moving both colour curve controls to the right (positive values) will enhance the effect of that colour throughout the tonal range. The White Curve (R, G or B) always controls the bright end of the tonal range and the Black Curve (R, G or B) the dark end. Because curves can be complex to visualize, Show Curves can be selected, which will superimpose over the image a graph which shows the shape of the Master Curve, and the offsets for Red, Green and Blue. The rest of the controls function as standard levels type controls used in image processing. The curves used in this section as special Catmul-Rom curves that have been chosen for their ease of use and way that they adjust video images. Because of the power of the curves section to change the tonal values of the image, it can either be applied first or last in sequence. Dither is a random dot pattern that helps to break up banding artifacts, and can be applied normally, or Strongly, which produces a subtle grain to the image.

Notes
Curves Bypass On on
off
Turns the Curves effect on or off.
Apply Curves First on
off
Allows you to choose whether the curves effect works on image data first or last in sequence. This can produce very different results depending on what you are doing.
Show Curves on
off
This is a diagnostic tool so that you can see what your colour curves are doing visually. It does not change the final render - only the preview.
Dither? on
off
Dither can help break up any posterisation that can occur with use of strong levels or curves by slightly increasing the noise in the image.
Strong Dither? on
off
If you are using Dither, then this will make the effect stronger.
White Level 0 to 255 Adjusts the overall white level of the image. Reducing this will make more of the brighter parts of the image brighter and brighter.
Black Level 0 to 255 Adjusts the overall black level of the image. Increasing this will make more of the darker parts of the image darker and darker.
By reducing the White Level and increasing the Black Level you will increase the contrast of the image.
Gamma -1 to 1 Adjusts the gamma of the image, which is how light or dark the mid-tones of the image are. A value of 0 is no adjustment. Increasing the gamma will brighten mid-tones, while decreasing it will darken mid-tones.
White Output 0 to 255 Controls the brightness of the brightest areas of the image. Lowering this control will make the brightest highlights darker
Black Output 0 to 255 Controls the brightness of the darkest areas of the image. Increasing this control will make the darkest shadows brighter.
White Curve Master -100 to 100 Adjusts the shape of the S curve in the bright areas of the image.
Black Curve Master -100 to 100 Adjusts the shape of the S curve in the dark areas of the image.
White Curve R -100 to 100 Adjusts the shape of the S curve in the bright regions for the red channel.
Black Curve R -100 to 100 Adjusts the shape of the S curve in the dark regions for the red channel.
White Curve G -100 to 100 Adjusts the shape of the S curve in the bright regions for the green channel.
Black Curve G -100 to 100 Adjusts the shape of the S curve in the dark regions for the green channel.
White Curve B -100 to 100 Adjusts the shape of the S curve in the bright regions for the blue channel.
Black Curve B -100 to 100 Adjusts the shape of the S curve in the dark regions for the blue channel.
