How AI Video Upscaler Works

Upload your video

Drop in the clip you want sharpened — a 720p export, an old recording, or AI-generated footage that came out soft. You can upscale videos up to 30 seconds long.

The Crystal Upscaler rebuilds detail

The model reconstructs edges, textures, and fine detail as it scales the frame up to 4K, so the result reads as genuinely higher resolution rather than a stretched, blurry version of the original.

Pay by clip length

Cost scales with duration: a 5-second clip is 3 credits, 10 seconds is 4 credits, and 15 seconds is 5 credits, so you know the price before you run it.

Download the 4K version

Export the upscaled video ready to publish to TikTok, Reels, YouTube Shorts, or reuse in a larger edit that demands crisp source footage.

Frequently Asked Questions

How do I upscale a video to 4K?

Upload your clip to Viralance's AI Video Upscaler and the Crystal Upscaler rebuilds detail while scaling the frame up to 4K. A 5-second video costs 3 credits, 10 seconds costs 4 credits, and 15 seconds costs 5 credits, and you can process clips up to 30 seconds long.

How much does it cost to upscale a video?

Pricing scales with clip length: 3 credits for 5 seconds, 4 credits for 10 seconds, and 5 credits for 15 seconds. Credits come from one-time packages with no subscription, so you only pay for the footage you actually upscale.

What AI model powers the video upscaler?

Viralance uses the Crystal Upscaler, which reconstructs edges, textures, and fine detail as it raises the resolution to 4K, rather than simply enlarging and blurring the existing pixels the way a basic resize does.

Can I upscale low-resolution or 720p footage?

Yes. The tool is built to take soft or low-resolution video — including 720p exports and AI-generated clips that came out blurry — and rebuild it at up to 4K, so it holds up on large screens and when the frame is cropped or zoomed.

What is the longest video I can upscale?

You can upscale clips up to 30 seconds long in a single job. A 15-second clip costs 5 credits, so short-form videos for TikTok, Reels, and Shorts fit comfortably within the limit.

Does upscaling actually add detail or just make the file bigger?

The Crystal Upscaler reconstructs detail as it scales, sharpening edges and texture rather than only increasing the pixel count. The result is a genuinely crisper 4K frame, not just a larger, equally soft copy of the source.
