Motion Types

Camera Movement

MovementPrompt KeywordEffect
Push in / Dolly forward"slow dolly forward", "camera pushes in"Increasing intimacy/focus
Pull out / Dolly back"camera pulls back", "slow zoom out"Reveal, context
Pan left/right"camera pans slowly to the right"Scanning, following
Tilt up/down"camera tilts upward"Revealing height
Orbit"camera orbits around the subject"3D exploration
Crane up"camera rises upward"Grand reveal

Subject Motion

TypePrompt Examples
Natural elements"water rippling", "clouds drifting", "leaves rustling in breeze"
Hair/clothing"hair blowing gently in wind", "dress fabric flowing"
Atmospheric"fog slowly rolling", "dust particles floating in light beams"
Character"person slowly turns to camera", "subtle breathing motion"
Mechanical"gears turning", "clock hands moving"
Liquid"coffee steam rising", "paint dripping", "water pouring"

Prompting Best Practices

The Golden Rule: Subtle > Dramatic

AI video models produce better results with gentle, subtle motion than dramatic action. Requesting too much movement causes distortion and artifacts.

Copy & paste โ€” that's it
โŒ "person running and jumping over obstacles while the camera spins"
โœ… "person slowly walking forward, gentle breeze, camera follows alongside"

โŒ "explosion with debris flying everywhere"
โœ… "candle flame flickering gently, warm ambient light shifting"

โŒ "fast zoom into the eyes with dramatic camera shake"
โœ… "slow dolly forward toward the subject, subtle focus shift"

Prompt Structure

Copy & paste โ€” that's it
[Camera movement] + [Subject motion] + [Atmospheric effects] + [Mood/pace]

Examples by Scenario

Copy & paste โ€” that's it
# Landscape animation
belt app run falai/wan-2-5-i2v --input '{
  "prompt": "gentle camera pan right, water reflecting moving clouds, trees swaying slightly in breeze, warm golden light, peaceful and slow",
  "image": "landscape.png"
}'

# Portrait animation
belt app run falai/wan-2-5-i2v --input '{
  "prompt": "subtle breathing motion, slight head turn, natural eye blink, hair moving gently, soft ambient lighting shifts",
  "image": "portrait.png"
}'

# Product shot animation
belt app run bytedance/seedance-2-0 --input '{
  "prompt": "slow 360 degree orbit around the product, gentle spotlight movement, subtle reflections shifting, premium product showcase, smooth motion",
  "image": "product.png",
  "generate_audio": true
}'

# Fabric/cloth animation
belt app run falai/fabric-1-0 --input '{
  "prompt": "fabric flowing and rippling in gentle wind, natural cloth physics, soft movement",
  "image": "fabric-scene.png"
}'

# Architectural visualization
belt app run falai/wan-2-5-i2v --input '{
  "prompt": "slow dolly forward through the entrance, slight camera tilt upward, ambient light filtering through windows, dust particles in light beams",
  "image": "building-interior.png"
}'

Duration Guidelines

DurationQualityUse For
2-3 secondsHighest qualityGIFs, looping backgrounds, cinemagraphs
4-5 secondsHigh qualitySocial media posts, product reveals
6-8 secondsGood qualityShort clips, transitions
10+ secondsQuality degradesAvoid unless stitching shorter clips

Extending Duration

For longer videos, generate multiple short clips and stitch:

Copy & paste โ€” that's it
# Generate 3 clips from the same image with progressive motion
belt app run falai/wan-2-5-i2v --input '{
  "prompt": "slow pan left, gentle water motion",
  "image": "scene.png"
}' --no-wait

belt app run falai/wan-2-5-i2v --input '{
  "prompt": "continuing pan, clouds shifting, light changing",
  "image": "scene.png"
}' --no-wait

# Stitch together
belt app run infsh/media-merger --input '{
  "media": ["clip1.mp4", "clip2.mp4"]
}'

The Full Workflow

Still-to-Final-Video Pipeline

Copy & paste โ€” that's it
# 1. Generate source image (best quality)
belt app run bytedance/seedream-4-5 --input '{
  "prompt": "cinematic landscape, misty mountains at dawn, lake in foreground, dramatic clouds, golden hour, 4K quality, professional photography",
  "size": "2K"
}'

# 2. Animate the image
belt app run falai/wan-2-5-i2v --input '{
  "prompt": "gentle mist rolling through the valley, lake surface rippling, clouds slowly moving, birds in distance, warm light shifting",
  "image": "landscape.png"
}'

# 3. Upscale video if needed
belt app run falai/topaz-video-upscaler --input '{
  "video": "animated-landscape.mp4"
}'

# 4. Add ambient audio
belt app run infsh/hunyuanvideo-foley --input '{
  "video": "animated-landscape.mp4",
  "prompt": "gentle nature ambience, distant birds, soft wind, water lapping"
}'

# 5. Merge video with audio
belt app run infsh/video-audio-merger --input '{
  "video": "upscaled-landscape.mp4",
  "audio": "ambient-audio.mp3"
}'

Cinemagraph Effect

A cinemagraph is a still photo where only one element moves (e.g., waterfall moving in an otherwise frozen scene). To achieve this:

  1. Generate the still image with the motion element clearly defined
  2. Prompt for motion only in that specific element
  3. Keep to 2-4 seconds for seamless looping
Copy & paste โ€” that's it
belt app run falai/wan-2-5-i2v --input '{
  "prompt": "only the waterfall is moving, everything else remains perfectly still, water cascading smoothly, rest of scene frozen",
  "image": "waterfall-scene.png"
}'
