Introducing WaveSpeedAI Video Fps Increaser on WaveSpeedAI

AI Video FPS Increaser: Double Your Video Frame Rate for Smoother Motion with WaveSpeedAI

Video FPS Increaser is now live on WaveSpeedAI, delivering instant AI-powered frame rate doubling through a simple REST API. If you’ve ever struggled with choppy 24fps footage, stuttery screen recordings, or low-frame-rate animations, this model eliminates the problem in seconds — upload your video, and get back a version with twice the frames and noticeably smoother motion.

Frame rate is one of the most overlooked factors in video quality. Viewers may not consciously notice frame rate, but they feel it: stuttery pans, jerky action sequences, and unnatural motion all erode perceived quality. The Video FPS Increaser uses AI frame interpolation to synthesize new intermediate frames between your existing ones, producing fluid playback that looks like it was captured at a higher frame rate from the start.

How the AI Video FPS Increaser Works

The Video FPS Increaser uses deep learning-based frame interpolation to analyze motion between consecutive frames and generate realistic intermediate frames. Rather than simple frame blending — which produces ghosting and blur — the model understands how objects move through the scene and synthesizes new frames that preserve sharp edges, accurate motion trajectories, and natural lighting.

Here’s what happens under the hood:

Motion analysis: The AI examines each pair of consecutive frames and estimates the optical flow — how every pixel moves from one frame to the next.
Frame synthesis: Using that motion data, the model generates a new frame that represents the midpoint between the two originals. The result looks like a real captured frame, not a blend.
Output assembly: The new frames are interleaved with the originals, effectively doubling the frame rate of your entire video.

The entire process runs on WaveSpeedAI’s optimized inference infrastructure with no cold starts — your job starts processing immediately, regardless of when you submit it. There’s nothing to configure: just provide a video, and the API handles the rest.

Key Features of the Video FPS Increaser

Double your frame rate instantly — Transform 24fps footage to 48fps, 30fps to 60fps, or any input frame rate to 2x, producing visibly smoother playback across all devices and platforms.
AI-synthesized frames, not blends — Generated frames are created through neural network inference, not simple averaging, which means sharp details, minimal ghosting, and natural motion.
Works on any video content — Talking heads, fast action, cinematic footage, screen recordings, animations, and gameplay — the model handles diverse content types without manual tuning.
Zero-configuration workflow — No parameters to set, no presets to choose. Upload a video and get the result. This makes it ideal for batch processing pipelines where simplicity matters.
No cold starts, instant processing — WaveSpeedAI’s infrastructure keeps models warm, so your request starts processing the moment it arrives.
Affordable per-second pricing — At $0.008 per second of input video, processing a 60-second clip costs less than $0.50.

Best Use Cases for the AI Video FPS Increaser

Slow-Motion Video from Standard Footage

You shot a clip at 30fps but want a smooth slow-motion version. Simply slowing down 30fps footage results in choppy, unwatchable output. The Video FPS Increaser doubles the frame rate first, giving you the extra frames needed to slow the clip to 50% speed while maintaining fluid motion. For deeper slow-motion, pair it with RIFE Video Interpolation, which supports up to 16x frame multiplication.

Upgrading Legacy or Archival Video

Old camcorder footage, security camera recordings, and archived content often sit at 15–24fps. Doubling the frame rate brings these videos up to modern playback standards, making them suitable for reuse in documentaries, corporate retrospectives, or social media compilations without looking dated.

Smoother Animation and Motion Graphics

Animators and motion designers often render at lower frame rates to save time. Running the output through the FPS Increaser adds the in-between frames automatically — a process that traditionally required hours of manual tweening or expensive render time. This is especially valuable for indie creators working with limited compute budgets.

Platforms like TikTok, Instagram Reels, and YouTube Shorts reward smooth, high-quality video in their algorithms. Upgrading a 24fps clip to 48fps or higher can make content feel more polished and professional, improving viewer retention and engagement metrics.

Game Recording and Streaming Highlights

Gameplay captures from older hardware or performance-constrained recordings often drop below 30fps. The FPS Increaser smooths out these dips, making highlight reels and montages look consistently fluid without re-recording on better hardware.

AI-Generated Video Enhancement

AI video generation models often output at lower frame rates (typically 8–16fps) to reduce compute costs. Running the output through the Video FPS Increaser is a fast, affordable post-processing step that dramatically improves the perceived quality of AI-generated clips. Combine it with the Video Upscaler for both smoother motion and higher resolution.

Screen Recordings and Tutorials

Screen recording software sometimes captures at variable or low frame rates, especially on resource-constrained machines. The FPS Increaser fixes the resulting choppiness, making software demos and tutorials look crisp and professional.

Video FPS Increaser Pricing and API Access

Pricing

Metric	Cost
Per second of input video	$0.008
Minimum charge	1 second

A 30-second video costs $0.24. A 5-minute video costs $2.40. No subscriptions, no minimum commitments — pure pay-per-use.

API Example

import wavespeed

output = wavespeed.run(
    "wavespeed-ai/video-fps-increaser",
    {"video": "https://example.com/my-video.mp4"},
)

print(output["outputs"][0])  # URL to the smoothed video

That’s it — one input field (video), one API call. Provide a publicly accessible video URL or upload directly. The API returns a URL to your frame-rate-doubled output.

Tips for Best Results with the AI Video FPS Increaser

Use the highest-quality source available. Frame interpolation works best with clean, sharp input. If your source is heavily compressed or noisy, artifacts in the original can be amplified in the generated frames.
Well-lit footage produces the cleanest results. Low-light video introduces noise and grain that can confuse motion estimation. If possible, use well-exposed source material.
Combine with upscaling for maximum quality. For the best results, run the FPS Increaser first (to double frame rate), then pass the output through WaveSpeedAI’s Ultimate Video Upscaler to increase resolution — smooth motion at higher detail.
For extreme slow motion, use RIFE instead. The Video FPS Increaser is optimized for a clean 2x frame rate boost. If you need 4x, 8x, or 16x interpolation for dramatic slow-motion effects, RIFE Video Interpolation offers multi-step interpolation with finer control.
Shoot at the highest native frame rate your camera supports. If you know you’ll apply interpolation later, capturing more real frames gives the AI better data to work with.

Frequently Asked Questions About the Video FPS Increaser

What is the Video FPS Increaser?

The Video FPS Increaser is an AI model on WaveSpeedAI that doubles your video’s frame rate by synthesizing new intermediate frames using deep learning-based frame interpolation, resulting in smoother, more fluid motion.

How much does the Video FPS Increaser cost?

Can I use the Video FPS Increaser via API?

Yes. WaveSpeedAI provides a REST API that accepts a video URL and returns the frame-rate-doubled output. It works with any programming language and requires no GPU setup on your end.

What types of video work best with AI frame interpolation?

Well-lit footage with clear motion produces the best results. The model handles a wide range of content — live action, animation, screen recordings, and AI-generated video — but heavily compressed or extremely noisy input may reduce interpolation quality.

What’s the difference between the Video FPS Increaser and RIFE?

The Video FPS Increaser provides a simple, zero-configuration 2x frame rate boost optimized for straightforward use cases. RIFE offers more granular control with 1–4 interpolation steps (up to 16x frame multiplication), making it better suited for extreme slow-motion effects and professional workflows requiring fine-tuned interpolation.
