Keyframe Requirements

​
Technical Specifications

  • Number of Frames: 2-20 keyframes
  • Formats: JPG, PNG, WebP
  • Max Size: 10MB per frame
  • Resolution: Consistent across all frames (1920x1080 recommended)
  • Aspect Ratio: Must be identical for all frames

​
Content Guidelines

  • Clear progression between frames
  • Consistent lighting across frames
  • Similar composition and framing
  • Logical motion sequence
  • High quality, sharp images

​
Frame Rate Options

Cinematic Standard
  • Film-like motion blur
  • Cinematic feel
  • Smaller file size
  • Best for: Artistic projects, film-style content

​
Interpolation Settings

​
Interpolation Strength

Minimal Interpolation
  • 2-4 frames between keyframes
  • More visible steps
  • Faster processing
  • Best for: Stop-motion style, stylized animation

​
Motion Blur

  • None: Sharp frames, no blur
  • Light: Subtle motion blur
  • Medium: Natural motion blur
  • Heavy: Dramatic motion blur effect

​
Use Cases

​
Stop-Motion Animation

Create smooth stop-motion videos 
Keyframes: 10-15 frames of stop-motion sequence
Frame Rate: 24 fps
Interpolation: Low (2-3 frames)
Motion Blur: None
Result: Stylized stop-motion with slight smoothing

​
Product Animation

Smooth product rotation or transformation 
Keyframes: 8 frames of product at different angles
Frame Rate: 30 fps
Interpolation: High (15 frames)
Motion Blur: Light
Result: Smooth, professional product showcase

​
Character Animation

Create character movement sequences 
Keyframes: 12 frames of character poses
Frame Rate: 24 fps
Interpolation: Medium (8 frames)
Motion Blur: Medium
Result: Fluid character animation

​
Time-Lapse Smoothing

Smooth out time-lapse sequences 
Keyframes: 20 time-lapse photos
Frame Rate: 30 fps
Interpolation: Medium (6 frames)
Motion Blur: None
Result: Smooth time-lapse video

​
Best Practices

  • Plan your sequence before shooting
  • Maintain consistent camera position
  • Use tripod for stability
  • Mark positions for repeatability
  • Shoot more keyframes than needed
  • Use consistent lighting across all frames
  • Avoid auto-exposure changes
  • Manual camera settings recommended
  • Same white balance for all frames
  • Keep movements simple between frames
  • Avoid large jumps in position
  • Smooth, gradual changes work best
  • Test with fewer frames first
  • Use high-resolution images
  • Ensure sharp focus on all frames
  • Check for consistent framing
  • Preview before final generation

​
Advanced Techniques

​
Easing Control

Control acceleration and deceleration:
  • Linear: Constant speed throughout
  • Ease In: Start slow, speed up
  • Ease Out: Start fast, slow down
  • Ease In-Out: Slow start and end, fast middle

​
Variable Interpolation

Different interpolation between different keyframe pairs:
  1. Upload all keyframes
  2. Set custom interpolation for each transition
  3. More frames for complex movements
  4. Fewer frames for simple transitions

​
Hybrid Animation

Combine with other techniques:
  • Start with keyframes
  • Generate interpolated video
  • Use as reference for further AI generation
  • Add effects or modifications

​
Workflow Examples

​
Stop-Motion Workflow

  1. Set up scene and camera
  2. Take photo of starting position
  3. Move subject slightly
  4. Take next photo
  5. Repeat 10-15 times
  6. Upload frames to Zoice
  7. Set low interpolation
  8. Generate smooth video

​
Product Rotation Workflow

  1. Place product on turntable
  2. Take photo every 45 degrees (8 total)
  3. Ensure consistent lighting
  4. Upload frames in order
  5. Set high interpolation
  6. Add light motion blur
  7. Generate smooth rotation

​
Character Animation Workflow

  1. Draw or pose character in key positions
  2. Capture 8-12 keyframes
  3. Ensure consistent scale and position
  4. Upload sequence
  5. Set medium interpolation
  6. Add natural motion blur
  7. Generate fluid animation

​
Troubleshooting

  • Increase interpolation frames
  • Check keyframe consistency
  • Ensure smooth progression
  • Add motion blur
  • Reduce interpolation strength
  • Ensure consistent lighting
  • Check for camera movement
  • Use higher quality keyframes
  • Adjust easing settings
  • Reduce large jumps between frames
  • Add more keyframes
  • Lower interpolation count
  • Use same camera settings for all frames
  • Maintain consistent resolution
  • Check focus on all frames
  • Ensure proper exposure
Large changes between keyframes may result in unpredictable interpolation. Keep movements gradual for best results.
Start with a simple 2-3 frame test to verify your setup before shooting all keyframes.
