Removes temporal flickering from the Source
clip using a Matte clip to specify the area where the average
brightness should remain constant. To use this effect, select a
Source frame that has the desired brightness within the Matte, and hit
the Set Hold Level button. When other frames are processed, their
brightness will be scaled so the average brightness within the Matte
is equal to the Hold Level. You can keyframe different Hold Level
values over time to account for desirable brightness changes.
In the Sapphire Time effects submenu.
Source: The current layer. The clip to remove flicker from.
Matte: Defaults to None. This clip specifies which Source areas to measure the
flicker from. If this input is not provided, the Alpha of the
Source input is used as the Matte instead. It can be inverted with
the Invert Matte parameter.
- Hold Level: Default: 0.5, Range: 0.01 to 2.
The requested average output brightness for the
area within the Matte.
- Set Hold Level: Push-button.
Pressing this button has a side effect of setting
the Hold Level parameter to the average Source brightness within the Matte at
the current frame. It causes the output to equal the Source at this frame.
This button retains no value itself, and is turned back off immediately
after being pushed. On FCP, this pushbutton could not implemented so you need to
adjust the Hold Level manually.
- Matte Use:
Popup menu, Default: Alpha.
Determines how the Matte input channels are used to make
a monochrome matte.
- Luma: the luminance of the RGB channels is used.
- Alpha: only the Alpha channel is used.
- Invert Matte: Check-box, Default: off.
If on, inverts the Matte input so the effect is applied
to areas where the Matte is black instead of white. This has no effect
unless the Matte input is provided.
Popup menu, Default: Normal.
Determines the method used for dealing with
- All Opaque: Use this option to render slightly faster when
the input image is fully opaque with no transparency (alpha=1).
- Normal: Process opacity normally.
- As Premult: Process as if the image is already in
premultiplied form (colors have been scaled by opacity). This option
also renders slightly faster than Normal mode, but the results will
also be in premultiplied form, which is sometimes less correct.
