Editorial Guidance

Hook first 3 s. Faces, action, or striking motion graphics before any dialogue‑driven cuts.
No text cards or subtitles—they’ll likely fall under UI chrome.
Avoid fade‑ups from black; landing autoplay starts immediately.
Loop‑friendly end. Use cross‑dissolve or hold‑frame that can restart invisibly.

Background Trailer tips

Atmospheric motion – slow‑motion, drone drifts, dolly pushes, or gently moving portraits; avoid abrupt handheld shakes.
Single focal theme – pick one character, location, or motif rather than jump‑cut story beats.
Readable in silence – convey genre through colour palette, lighting, costume and action; assume zero audio.
Front‑loaded spectacle – first frame should feel like a poster come alive: bold subject, cinematic lighting.
Logo sting (optional) – a kinetic title appear/disappear in the last 3 s can brand the loop, but keep < 8 % screen height.
Light for legibility – favour mid/high‑key exposure so UI text contrasts over darker zones.
Mask the loop – end on motion that naturally resets (lens flare, water ripple, whip‑pan) to hide the seam.
No burnt‑in captions – laurels, quotes and age ratings must be supplied as separate overlays, not embedded.
VFX passes welcome – parallax layers, particle glints or subtle light leaks add premium sheen. Use cross‑dissolve or hold‑frame that can restart invisibly.

Background Trailer Conversion Success Tips

Title (anonymised)	Visual Hook Used	Outcome
Thriller “Project X”	Snap‑zoom on protagonist’s fearful eyes + flash‑cut logo	+18 % play‑starts vs. story‑cut trailer
Nature Doc Series	2‑s sweeping drone vista with soaring bird silhouette	+14 % click‑through on mobile
Indie Rom‑Com	Pastel‑graded slow‑motion meet‑cute, looping seamlessly	+11 % viewer dwell time before scroll
Music Biopic	Kinetic typography synced to drum hit (no audio)	+9 % trailer completion, +7 % play‑starts
Festival Drama	Award laurel overlay in final 3 s, subtle shimmer	+5 % play‑starts among new visitors

Key Insight : Visual hooks that communicate genre + emotion within 2 s consistently outperform dialogue‑led edits. The more a background trailer feels like a living poster, the higher the conversion.
