Special Effects/Starglow
The Starglow operator adds a glowing star effect to the brightest parts of a frame. It makes highlights sparkle and shine, giving the impression of light reflecting or shimmering. This can be used to bring extra emphasis to bright spots, add a cinematic glow, or make reflections more eye-catching.
Options
- Luminance threshold - Sets the luminance level required for areas to glow.
- Softness - Controls how far the glow spreads around bright areas. Higher values create a softer glow.
- Boost - Adjusts the intensity of the glow.
- Opacity - Controls the transparency of the starglow layer. Range: 0–100. At 0, only the glowing areas are visible; at 100, the glow blends fully with the frame.
Length
- Streak length - Sets the maximum length of all starglow streaks.
- Up length - Sets the length of the upper streak.
- Down length - Sets the length of the bottom streak.
- Left Length - Sets the length of the left streak.
- Right length - Sets the length of the right streak.
- Up left length - Sets the length of the upper left streak.
- Up right length - Sets the length of the upper right streak.
- Down left length - Sets the length of the bottom left streak.
- Down right length - Sets the length of the bottom right streak.
Tip
This operator often requires some experimentation with its settings to achieve the desired effect.
