AI Frame Interpolation: Turn Choppy Video into Smooth 60fps

March 26, 2026 • ContentaSoft Team

Video shot at 24 or 25 frames per second looks cinematic on a theater screen, but on a modern 60Hz or 120Hz monitor it can look choppy and stuttery. Old camcorder footage, anime, classic films, and surveillance recordings all suffer from this low-frame-rate problem.

AI Video Enhancer Studio uses RIFE frame interpolation to generate the missing frames between existing ones. The result is smooth, fluid motion — without re-shooting anything.

What Is Frame Interpolation?

Frame interpolation is the process of generating new intermediate frames between existing ones. If your video has 24 frames per second and you want 60fps, the AI needs to create 36 new frames for every 24 original frames — predicting what the scene looked like between each pair of real frames.

Unlike simple frame duplication (which just repeats frames and still looks choppy) or blending (which creates ghosting), AI interpolation analyzes motion in the scene and synthesizes genuinely new frames that look natural.

How RIFE Works

RIFE (Real-Time Intermediate Flow Estimation) is a neural network designed specifically for frame interpolation. It analyzes two consecutive frames and estimates the optical flow — how each pixel moves between them — then synthesizes a new frame at any point in between.

• Fast: RIFE processes frames in real time on modern GPUs, making it practical for long videos and batch processing.
• High quality: The model handles complex motion, occlusion, and lighting changes better than traditional optical flow algorithms.
• Flexible: Supports 2×, 3×, 4×, and higher multiplication factors — convert 24fps to 48, 72, 96, or 120fps.

Use Cases

• Classic film restoration — Convert 24fps film to 60fps for smooth playback on modern displays. Ideal for old home movies, documentaries, and archival footage.
• Slow-motion creation — Interpolate to 120fps or higher, then play back at 30fps for smooth 4× slow motion — without needing a high-speed camera.
• Anime and animation — Most anime is animated at 12–24fps. RIFE interpolation smooths out the motion while preserving the art style.
• Game recordings — Smooth out 30fps gameplay captures for YouTube or Twitch highlights that look better on high-refresh-rate monitors.
• Surveillance and dashcam — Low frame rate security footage (10–15fps) becomes much easier to review and analyze when interpolated to 30fps.

Frame Rate Targets

Choose your target based on where the video will be viewed:

Source FPS	Target FPS	Best For
24 fps	60 fps	Smooth playback on 60Hz monitors, YouTube uploads
24 fps	120 fps	High-refresh displays, VR content, 4× slow motion
30 fps	60 fps	Phone footage, game recordings, webcam video
15 fps	30 fps	Surveillance footage, old webcam recordings, screencasts

How to Use Frame Interpolation

1. Open AI Video Enhancer Studio and add your video files.
2. Enable Frame Interpolation in the enhancement pipeline.
3. Select your target frame rate (60fps, 120fps, or custom).
4. Choose GPU acceleration if available (NVIDIA CUDA or AMD DirectML).
5. Click Start. The AI generates missing frames and encodes the output in one pass.

Batch Processing

AI Video Enhancer Studio processes entire folders of video files. Add a directory, set your interpolation target, and let it run through every file automatically. Progress tracking shows estimated time remaining per file and for the entire batch.

You can combine frame interpolation with other AI enhancements in the same pipeline — upscale to 4K and interpolate to 60fps in a single pass, for example.
