Runway's Gen-4 works best from a reference image: the image carries identity, and the prompt describes motion, camera and light. These 15 prompts cover establishing shots, product motion and character continuity, with what to check in each result. On 8frame, Runway is available as Gen-4 Turbo image-to-video (8 credits a second, 2 to 10 seconds, so 16 to 80 credits a clip) and Act Two for transferring a performance from a driving video (8 credits a second of reference, 3 to 30 seconds).
Correction, 2026-09-30: the first version of this page said Runway is not on the 8frame canvas; Gen-4 Turbo image-to-video and Act Two are. It also presented the prompts as tested with observed results, and stated output lengths, 4K output, native audio and editing limits for Runway that we cannot source. The prompts and the formula stay; the rest is gone.
TL;DR
- Formula: reference anchor + subject action + camera move + lens and light + pacing.
- On 8frame: Gen-4 Turbo image-to-video, 40 credits for 5 seconds, 80 for 10; Act Two 8 credits per second of the driving video.
- One start image per clip. For shots with two characters, or a character and a product, compose one start frame first.
- No audio setting on this route. Add sound in the edit, or pick a model with audio for shots that need it.
The prompt formula
Five parts, in order: Reference anchor + Subject action + Camera move + Lens and lighting + Pacing.
Lead with what the reference fixes (character, product or location), so the text describes motion around it rather than re-describing the subject. Name the camera move (dolly in, orbit, aerial descent, tracking); "cinematic camera" is not a move. Give lens character, light direction and colour temperature. Close with pacing. Length and shape are node settings, not prompt text. The prompts keep their sound cues for routes that generate audio; on 8frame's Gen-4 Turbo they are ignored.
Establishing shots
1. Aerial descent over a coastal town
Reference: wide daytime plate of a Mediterranean coastal town. Slow aerial descent toward the rooftops, camera rotating clockwise as it drops. Magic-hour light, long shadows from chimneys, orange-pink horizon. Anamorphic scope, deep focus. Slow, deliberate speed. Ambient wind gaining faint street noise.
What to check: That the rooftops stay the town in your reference as the camera drops, and the rotation keeps one direction.
2. Dolly-in on a lighthouse at dusk
Reference: rocky promontory with a lighthouse. Slow dolly in from extreme wide to wide, lighthouse centered throughout, waves breaking below. Soft fog reducing distant contrast, warm amber beacon against blue-hour sky. Scope ratio, no subjects. Wind and distant surf.
What to check: Rock geometry holding through the push and the beacon keeping a clean glow against the sky.
3. Interior reveal, slow pan
Reference: a grand library reading room, empty. Camera pans slowly left to right across the room from a fixed position, revealing tall shelves and shafts of dust-lit window light. Cool ambient shadow, warm directional sun beams. Deep focus, symmetrical framing. Quiet room tone with faint page rustle.
What to check: Shelf detail across the whole pan. Use the full 10 seconds only if the move needs it; every second is billed.
4. Wide desert at midday
Reference: vast salt flat with a distant mountain ridge. Static tripod frame, telephoto compression, heat shimmer above the white surface, a lone figure walking away in the far distance. Bleached, glaring light. Faint wind trace only.
What to check: The lone figure staying one figure and the shimmer reading as heat, not noise.
5. Tracking push through a rain alley
Reference: narrow rain-slicked alley at night, neon signage. Steady tracking push forward, Steadicam feel with slight sway, wet cobblestones reflecting neon in the puddles, steam rising from a grate ahead. Anamorphic, deep focus, blue and pink neon. Rain, distant traffic, off-camera footsteps.
What to check: Reflections that match the neon above, and a sway that feels like a Steadicam rather than a shake.
Product motion
6. Hero rotation on a pedestal
Reference: front-label product shot, clean background. Product on a matte pedestal, camera orbits 180 degrees around it at eye level, single soft key from upper left. Shallow depth of field, dark seamless backdrop, subtle rim light. Slow orbit. Low studio hum.
What to check: The label through the orbit. Labels are the first thing to drift on a moving product.
7. Liquid pour, slow motion
Reference: the product bottle and a glass. Liquid pours from the bottle into the glass, camera static in tight medium, backlit so the stream glows. Slow motion at 40%, high shutter clarity, cool key with warm rim. Shallow focus on the stream. Pour sound, glass ambience.
What to check: The stream's shape and glow. On 8frame this route starts from one image, so frame the bottle and glass together in the start frame.
8. Unboxing hands, tabletop
Reference: full product packaging. Hands lift the product from an open box on a white desk, tilt it up to camera to show the label, then set it down. Medium shot, static frame slightly below desk height, soft window light. Natural, unhurried pace. Paper and cardboard sound.
What to check: Hands and the box lid through the lift, and the label when it faces camera.
9. Product on a moving surface
Reference: the product. Product sits on a slowly rotating turntable, camera locked in three-quarter view, light sweeping across the surface as it turns to reveal texture and finish. Controlled specular highlights, dark studio surround. Steady rotation. Minimal ambient.
What to check: That the finish reveals itself as the light sweeps, and the product doesn't change shape as it turns.
10. Macro texture pull
Reference: close product detail. Extreme macro on the product surface, camera pulls back slowly from macro to full product, revealing the object in context. Shallow-to-deep focus shift as it pulls, soft top light. Deliberate pull speed. Quiet.
What to check: Focus moving from macro to full product without the object changing on the way.
Character continuity
11. Reference-locked character walking
Reference: full-body portrait of the character. The same character walks toward camera down a sunlit city street, slow tracking pull matching her pace, wardrobe and face exactly as the reference. Golden-hour backlight, shallow depth of field, warm haze. Natural walk speed. Street ambience, footsteps.
What to check: Face and wardrobe against your reference for the whole walk.
12. Close-up performance with Act-Two
Reference: character portrait, plus a driving performance video of the actor delivering the line. Close-up on the character's face as she speaks, subtle head tilt and blink inherited from the driving clip. Practical warm key, cool fill, shallow focus on the eyes. Real-time. Room tone, quiet.
What to check: Lip and eye movement against the driving clip. This one uses Runway Act Two, not Gen-4 Turbo image-to-video.
13. Two-shot continuity across a cut
Reference: the character portrait. Shot A: medium shot, she sits at a cafe table and looks up. Shot B: close-up, she smiles and speaks. Same character, wardrobe, and cafe across both shots. Handheld, warm window light from camera left. Natural pace. Cafe ambience.
What to check: Generate the two shots as two clips from the same reference, then compare face, wardrobe and set across the cut.
14. Over-the-shoulder dialogue frame
Reference: two character portraits. Over-the-shoulder from behind character A onto character B across a table, B in sharp focus speaking, A's shoulder soft in foreground. Static frame, restaurant practical lighting, warm tungsten. Shallow depth of field. Low restaurant ambience.
What to check: Two characters need two references. Compose both into one start frame first (for example with Nano Banana, up to 10 references), then animate it.
15. Character interacting with a product
Reference: character portrait plus product front-label shot. She picks the product up from a counter, turns it toward camera, and reads the label. Handheld medium shot, soft morning kitchen light. Natural, authentic pacing. Kitchen ambience.
What to check: The label when she turns the product toward camera. Put the character and the product in one start frame first; set 9:16 on the node.
Common mistakes
Over-describing the subject. The reference carries identity. Describe motion, camera and light; let the image do the rest.
No named camera move. Name it, and for orbits give the arc in degrees.
Several references for one clip. Gen-4 Turbo image-to-video starts from one image. Build a single start frame that already contains everything that must appear.
Prompting expressions in text. For dialogue and expression, drive the performance with Act Two and a real clip instead.
Paying for long clips you'll trim. Every second is billed at 8 credits. Generate the length you'll use.
