16:9 cinematic demo: J-Cut / L-Cut (Visual Setup).
Technique: A visual setup for split editing supplies a held listener and a source shot with enough handles for sound to arrive before picture.
Scene: A repair apprentice listens outside a room where a mentor tests a small bell mechanism.
Start: A: eye-height medium of the apprentice beside a closed workshop door.
Motion: Capture B for at least eight source seconds, with the strike at source 2 s. Picture A uses its source 0–4 s at output 0–4; B uses source 3–7 s at output 4–8. Begin B audio source 2–7 s at output 3–8, so the strike is heard one second before the ringing aftermath appears. Retain clean handles; there is no second strike. If audio is absent, this remains only a visual setup, not a completed J-cut.
End: The mentor steadies the now quiet bell with the striker held clear.
Camera: 50 mm rectilinear prime; fixed focal length within this plate, f/4, shutter 1/48s, ISO 400, 24fps.
Light: A broad 5600 K window at camera left supplies the key; a white floor returns weak fill. Keep the opposite wall dark and retain texture in pale surfaces. Lock exposure and white balance rather than letting the effect drive automatic corrections.
Color: Muted blue corridor and warm brass interior. Muted blue-grey shadows, warm-neutral midtones and ivory highlights; moderate saturation, gently lifted deepest blacks and a smooth highlight shoulder. Preserve differences between cloth, skin and hard surfaces instead of smoothing them into a single material.
Duration: 8s. Mode: multi_shot.
