AI frame interpolation
Higher resolution is only half the job; frame rate is the other half. UPSCALEVIDEO's 30fps to 60fps converter uses AI frame interpolation to generate the in-between frames your source never captured, turning choppy 24/30fps footage into smooth 60fps motion — gameplay, sports, animation, and screen recordings — in your browser, with no GPU on your side and no software to install.

How it works
No software to install and no account needed to start. Upload your clip, let the AI synthesize the missing frames, and download a smoother 60fps MP4. Frame interpolation runs on our GPUs, so your machine does none of the rendering.
Drag and drop an MP4, MOV, M4V, or MKV file up to 500MB and 60 seconds. Files are processed securely and never shared with third parties. No login required to try — your first conversion is free.
The model analyzes motion between your source frames and synthesizes the in-between frames needed to reach 60fps — doubling a 30fps clip or roughly 2.5× a 24fps clip. You don't configure optical-flow settings or pick a model; it just runs.
Compare the smoother 60fps version side-by-side with your original before committing, then download a high-bitrate MP4 that holds up on YouTube, social, and large displays.
What it does
Turn 30fps source into smooth 60fps output, or lift 24fps film and animation toward 60fps. The AI generates the intermediate frames your camera or recorder never captured, so motion stops looking choppy on modern 60Hz+ displays.
Frame interpolation is compute-heavy — that's why tools like Lossless Scaling and SVP lean on your own GPU. UPSCALEVIDEO runs every interpolated frame on our server GPUs, so a basic laptop, a Mac, or a Chromebook gets the same result without fans spinning up.
No Lossless Scaling purchase on Steam, no SVP setup, no Python/CUDA pipeline like the open-source options. Open the page in any browser, drop in a file, and download the 60fps result.
Fast motion is where low frame rate hurts most. Interpolation smooths panning, fast camera movement, and high-speed action so gameplay captures and sports clips look fluid instead of stuttery.
Slowing down 30fps footage normally reveals stutter. Interpolating to 60fps first gives a slow-mo edit far more frames to work with, so reduced-speed playback stays smooth instead of stepping.
Interpolation isn't magic — fast motion and scene cuts can still produce artifacts. UPSCALEVIDEO shows you a side-by-side preview against the original so you can confirm the result before downloading.
The key distinctions
These three get conflated constantly. Upscaling makes a video bigger (more pixels); enhancement makes it cleaner (sharper, less noisy); frame interpolation makes it smoother (more frames per second). UPSCALEVIDEO does all three — this page is about the frame-rate half.
| Aspect | Frame interpolation | Upscaling | Enhancement |
|---|---|---|---|
| What it changes | Frame rate — e.g. 30fps to 60fps | Resolution — e.g. 1080p to 4K | Quality — sharpness, noise, color |
| Adds more… | Frames per second | Pixels | Detail and cleanliness |
| Feels different? | Smoother motion | Sharper at larger size | Cleaner and crisper |
| Typical source | Choppy 24/30fps footage | Small or low-res footage | Noisy, soft, flat footage |
| Best used for | Gameplay, sports, animation, slow-mo | Clean footage that needs to be bigger | Grainy, shaky, or washed-out footage |
Use cases
30fps to 60fps FAQ
Upload your clip to UPSCALEVIDEO and let AI frame interpolation synthesize the in-between frames. A 30fps source becomes 60fps output because the model generates one new frame between each pair of originals; a 24fps source is lifted toward 60fps the same way. You don't tune optical-flow settings — the interpolation runs on our GPUs and you preview the result before downloading.
Frame interpolation is the process of generating new, in-between frames that your source video never captured, raising its frame rate. The AI studies how objects move between two real frames and synthesizes a plausible middle frame, then repeats that across the clip. Done well, 30fps footage plays back with the fluid motion of 60fps. It is separate from upscaling (more pixels) and enhancement (cleaner pixels).
Upscaling increases resolution — the number of pixels in each frame, for example 1080p to 4K. Frame interpolation increases frame rate — the number of frames per second, for example 30fps to 60fps. Upscaling makes each frame sharper and larger; interpolation makes motion smoother. They solve different problems and you can apply both.
It can. Interpolation is guessing the in-between frames, so fast motion, quick scene cuts, occlusion, and fine repeating textures can produce smearing, ghosting, or wobble. UPSCALEVIDEO shows you a side-by-side preview against the original so you can judge the result on your own clip before downloading. For most footage the improvement in smoothness is clear; for the hardest motion, previewing first matters.
Yes. Lossless Scaling is a paid Steam app that interpolates frames in real time on your own GPU. UPSCALEVIDEO is a browser-based alternative: free to start, no purchase, no GPU on your side, and it processes the file server-side so you download a finished 60fps MP4 rather than relying on real-time playback. Use it when you want a converted file rather than a live player.
No. Frame interpolation is genuinely compute-heavy, which is why desktop tools like Lossless Scaling, SVP, and the open-source options need your own GPU. UPSCALEVIDEO runs every interpolated frame on our server GPUs, so your graphics card is irrelevant — a basic laptop, a Mac without a discrete GPU, or a Chromebook all get the same result.
Yes. The same interpolation works on 24fps film and animation, lifting it toward 60fps. Be aware that 24fps has a deliberate cinematic cadence some viewers prefer; converting it changes that feel. Preview the result and decide whether the smoother motion suits your footage.
Yes. You can convert your first clip with no login at all — just open the page and drop in a file. An account is only needed later if you want to manage history, use paid features, or process longer clips.
UPSCALEVIDEO accepts MP4, MOV, M4V, and MKV files up to 500MB and 60 seconds. Output is a high-bitrate MP4 ready for YouTube, social platforms, and editing tools.
