Night lights that need a streak
Live plate. Auto Detect on the lamp. Anamorphic preset, then Size and Streak.
DaVinci Resolve Studio OFX
Anamorphic streak, ghosts, bloom. Auto-detect the practical, or place it by hand.
Drag the split. Left is the plate. Right is Flare Sauce on a selling setting, Anamorphic look.
Presets are a start, never locked. Tweak streak, ghosts, chroma, bloom and dirt after you pick one.
Auto Detect locks onto the hottest source and Hold stops it hopping between lights. Preview Detect tints qualifying pixels red in the viewer, never on the render. Turn Auto off and drag the target.
Low follows whichever light is brightest. High sticks unless something much hotter appears.
Threshold is visible. Red means it will count as a source.
Screen is the photographic default. Add is hotter. Mix pulls it off the plate.
Night practicals first. Then CG that still looks optically clean.
Live plate. Auto Detect on the lamp. Anamorphic preset, then Size and Streak.
Last node after the grade. Screen blend so highlights do not clip twice.
