Slow Motion Video#

Create smooth slow-motion videos by intelligently interpolating additional frames between existing ones. This tool uses advanced frame interpolation models to generate natural-looking slow motion effects from regular videos.

Overview#

  • Frame interpolation for smooth slow motion
  • Multiple interpolation models (RIFE and FILM)
  • Adjustable slowdown factor (2x-8x)
  • Optional ping-pong looping
  • FPS control and preservation

Quick Start#

  1. Visit Eden Create: Slow Motion Video tool
  2. Upload your video
  3. Choose interpolation factor (2-8x slower)
  4. Click "Create"

See API Reference section below for API usage examples.

Ask an Eden agent to "Slow Motion Video".

Basic Usage#

Required inputs:

  • Input video
  • Interpolation factor (2-8x)

Optional settings:

  • Output FPS
  • Interpolation model
  • Ping-pong looping

Technical Guidelines#

Frame Interpolation Settings#

  • Interpolation Factor: 2-8x (default: 2)
  • Output FPS: 1-60 (default: 24)
  • Supported Models:
  • RIFE 4.7
  • RIFE 4.9 (default)
  • FILM

Best Practices for Inputs#

  • Use high-quality source videos
  • Avoid videos with rapid scene changes
  • Keep input videos under 30 seconds
  • Ensure steady camera movement
  • Use progressive scan footage when possible

Advanced Features#

Interpolation Models#

  • RIFE: Fast and efficient, best for most uses
  • FILM: Higher quality but slower, better for extreme slow motion

FPS Control#

  • Default: 24fps
  • Range: 1-60fps
  • Option to preserve input video FPS

Ping-pong Looping#

  • Creates seamless forward-reverse loops
  • Doubles final output duration
  • Useful for creative effects

Tips for Best Results#

Technical Considerations#

  • Higher interpolation factors require more processing time
  • Consider frame rate compatibility with target platform
  • Monitor output file size with longer videos

Input Optimization#

  • Clean, stable footage works best
  • Avoid heavy motion blur
  • Well-lit scenes produce better results

Technical Details#

Base Technology#

  • Primary models: RIFE 4.7/4.9 and FILM
  • Default parameters:
  • Interpolation Factor: 2
  • FPS: 24
  • Model: RIFE 4.9

Limitations#

  • Maximum input resolution: 1920x1080
  • Maximum output duration: 60 seconds
  • Processing time increases with interpolation factor

Common Issues and Solutions#

Issue Solution
Artifacts in output Reduce interpolation factor
Slow processing Use RIFE instead of FILM model
Choppy results Ensure stable input footage
Output too fast/slow Adjust output FPS setting
