RIFE Video Interpolation generates smooth intermediate frames between existing video frames for higher frame rates and smoother motion. Ready-to-use REST inference API, best performance, no cold starts, affordable pricing.

Features

RIFE Video Interpolation uses the state-of-the-art Real-Time Intermediate Flow Estimation algorithm to increase your video’s frame rate by inserting synthetic frames between existing ones. The result is dramatically smoother motion — ideal for slow-motion effects, fixing choppy footage, or simply upgrading the visual quality of any clip.

Why Choose This?

• Smooth, natural motion Synthesized frames blend seamlessly with the original footage, eliminating stutters and judder without ghosting or blurring.

• Flexible interpolation steps Choose 1 to 4 interpolation frames per original frame pair to dial in exactly the level of smoothness you need.

• Works on any footage Talking heads, action shots, cinematic scenes, screen recordings — RIFE adapts to a wide range of video content.

• No local setup Upload, run, and download. No GPU required on your end.

Parameters

How to Use

1. Upload your video — provide the clip you want to smooth via URL or drag-and-drop.
2. Submit — process, preview, and download your interpolated video.

Pricing

$0.01 per second of input video, with a minimum charge of 1 second.

Best Use Cases

• Slow-motion effects — Dramatically slow down footage while maintaining smooth, fluid motion.
• Frame rate upscaling — Convert 24fps footage to a higher effective frame rate for a more cinematic or broadcast-ready feel.
• Fixing choppy video — Smooth out low-frame-rate recordings from older cameras, screen captures, or compressed sources.
• Animation smoothing — Increase the fluidity of animated sequences without re-rendering the source.

Pro Tips

• RIFE works best on well-lit, stable footage; heavily compressed or noisy input may produce less clean interpolation.
• For slow-motion use, shoot at the highest frame rate your camera supports, then interpolate further with RIFE.

Notes

• video is the only required field.
• Pricing is based on the duration of the input video at $0.01 per second, with a minimum charge of 1 second.
• Ensure video URLs are publicly accessible if using a link rather than a direct upload.

Duration limit

The maximum supported video duration is 10 minutes.
