AI Frame Interpolation
AI frame interpolation generates real intermediate frames between existing ones — not duplicated frames, not blended frames. The neural network analyzes motion between every pair of frames and synthesizes a genuine in-between frame, eliminating stutter and judder without ghosting.

How to Use AI Frame Interpolation
- Upload your video — any frame rate, MP4 / MKV / MOV / WebM all supported
- Pick your target frame rate (60, 120, or 240 fps)
- Choose Browser mode (free, FFmpeg minterpolate) or Server mode (AI on GPU)
- Click Process — the AI evaluates motion and generates new frames
- Download the interpolated video, ready for YouTube, social, or editing
Features
- Neural-network frame interpolation — state of the art for open-source AI
- Real synthesized frames, not duplicated or blended — eliminates stutter and ghosting
- Convert 24fps, 25fps, 30fps, or any source to 60fps / 120fps / 240fps
- Handles fast motion, occlusions, camera pans without warping
- Free browser fallback for short clips, GPU server mode for full-length video
- Works on MP4, MKV, MOV, WebM, and animated GIF
Frequently Asked Questions
- What is AI frame interpolation?
- Frame interpolation generates new frames in between the existing frames of a video — making 30fps look like 60fps, or unlocking smooth slow motion. The 'AI' variant uses a trained neural network to predict what those new frames should look like, instead of just blending or duplicating adjacent frames. The result is genuine motion smoothing without the ghosting artifacts of older algorithms.
- How is this different from FFmpeg minterpolate?
- FFmpeg's minterpolate uses motion vectors and blending — it's fast but produces visible artifacts on fast motion (ghost trails, blur smears). AI interpolation uses a neural network that learned realistic motion patterns from millions of video frames; the synthesized frames look like genuine new captures, not blended hybrids.
- Which AI model do you use?
- Our pipeline runs a state-of-the-art open-source frame interpolation model on GPU — the same family of models used by Topaz Video AI, Flowframes, and other commercial AI interpolation tools. We keep it updated to the most recent stable release.
- Why is AI frame interpolation slow?
- The neural network has ~10 million parameters and has to evaluate them for every pair of frames in your video. On CPU this would take many seconds per frame; our GPU server typically runs at 2-3× real time. Browser mode is faster because it falls back to FFmpeg minterpolate (no AI).
- Can I interpolate animated GIFs?
- Yes — upload a GIF and pick a target frame rate. Most GIFs are 10-15fps, so interpolating to 30 or 60fps makes the animation noticeably smoother. Output is back to GIF format (or MP4, your choice).
- Does it work for slow motion?
- That's one of the most popular uses. Interpolate a 30fps source to 120fps or 240fps, then play back at 30fps — you get 4× or 8× slow motion with no stutter, mimicking the look of a Phantom Flex camera.
