Starting footage: Original night footage I shot myself on my phone headlights/neon strong highlights, vertical 9:16. No stock, no sample footage What I asked the agent to do: In invideo Editor (Ultra mode), I asked the agent to research the viral Hail Mary effect, read the construction steps from a reference tutorial (leaving out the color work).... then build the whole effect as a custom shader on my clip via the timeline agent with exposed controls: highlight threshold, softness, trail length, trail taper strength, and mix. I finished with the duplicate clip + Screen blend layer. What I refined myself: I lowered the highlight threshold so only the brightest lights trail, extended trail length + taper, re-angled the trail direction to follow the camera move, and pulled the mix down to ~40% for a cleaner finish all directly on the editable timeline in invideo Editor.
