Frame Interpolation Node

​
Frame Interpolation

Make motion buttery smooth.
This node fills in the gaps between frames, creating fluid movement from choppy footage. Perfect for making AI-generated videos look more cinematic or smoothing out low-FPS recordings.

​
🪄 When to Use It

Use Frame Interpolation when your video feels stuttery or choppy. It works great for:
  • Smoothing AI videos — most AI generators output at 24fps or lower
  • Slow motion — add frames to stretch time smoothly
  • Gaming captures — make 30fps gameplay look like 60fps
  • Stop motion — blend frames for smoother animation
Skill level: Intermediate
Average time: 60–120 seconds depending on length and FPS
Cost: Medium-High

​
🎚️ Controls and Parameters

​
Video (Video, Required)

The footage you want to smooth out. Works with any video format.

​
Frame Rate Multiplier (Number)

How many new frames to add between existing ones:
  • 2x — doubles frame rate (24fps → 48fps, 30fps → 60fps)
  • 4x — quadruples frame rate (for extreme slow-motion)
💡 Tip: Most videos need 2x. Only use higher multipliers for slow-motion effects.

​
🎨 Available Models

​
VFI (Default)

Video Frame Interpolation engine designed for smooth motion. Intelligently analyzes movement between frames to generate natural in-between frames. Features:
  • Flexible frame rate multipliers (2x, 4x, or higher)
  • Optimized for AI-generated video smoothing
  • Works with any video format
💡 Tip: VFI is the only model for this node and handles all frame interpolation needs professionally.

​
🎨 What to Expect

Frame interpolation analyzes motion between frames and generates smooth in-between frames. Works best with:
  • Consistent motion — objects moving in predictable paths
  • Good source quality — clean, sharp footage
  • Simple scenes — fewer objects moving at once
Can struggle with:
  • Fast, erratic movement — quick cuts or camera shakes
  • Occlusion — objects appearing/disappearing between frames
  • Motion blur — already blurry footage gets worse
  • Scene cuts — interpolation doesn’t know when scenes change

​
💬 Quick Tips

  • Use Frame Interpolation as one of the last steps in your workflow
  • 2x multiplier is perfect for making 24-30fps feel like smooth 60fps
  • Works great on AI-generated videos which often feel choppy
  • Don’t interpolate footage that’s already 60fps — it won’t improve quality
  • If you see ghosting or artifacts, your source motion might be too fast or complex
  • Best used on videos with smooth, continuous motion
