Lens Flare

Lens Flare · screenshot coming soon

​
What this node does

This node composites a synthetic lens flare over a COMFYTV_VIDEO clip: a central glow at a chosen position, optional horizontal anamorphic streak, and a chain of “ghost” reflections marching across the frame. It runs on a Torch backend as an fx-spec pass and passes the clip through untouched when intensity is 0. It has a ▶ Run. Input and output are both COMFYTV_VIDEO. To hand the result to native ComfyUI nodes, insert a Bridge — see the bridge note.

​
When to use it

  • Add a flare pointing back at the sun/practical light for a cinematic or sci-fi feel.
  • Sell a hero shot or lens-driven transition.
  • Fake a light source reaction the original footage lacked.

​
Parameters

​
pos_x / pos_y

Where the flare’s bright source sits, each 0.0 to 1.0 across the frame (default pos_x 0.75, pos_y 0.25 — upper-right). The ghost chain runs from this point through the frame center.

​
intensity

Overall brightness of the flare, 0.0 to 3.0 (default 0.8). 0 disables the effect entirely.

​
size

Size of the central glow, 0.05 to 1.0 (default 0.25) as a fraction of the frame.

​
streak

Strength of the horizontal anamorphic streak through the flare center, 0.0 to 1.0 (default 0.5). Turn to 0 for a round flare with no streak.

​
ghosts

Number of secondary ghost reflections along the flare axis, integer 0 to 8 (default 5). More ghosts = a busier lens-reflection chain; 0 gives just the glow and streak.

Tips

  • Place pos_x/pos_y right on the brightest light in the shot so the flare reads as motivated.
  • Lower streak and ghosts for a subtle glow; raise both for a stylized, obvious flare.
  • Keep intensity moderate over bright backgrounds so the flare doesn’t blow out the whole frame.
  • Chromatic Aberration — pairs well for a full lens-character pass.
  • Lens Distort — the geometric lens counterpart.
