Video after AI upscaling to 4K - sharper detail and enhanced quality

If you have ever recorded a video on an older phone, downloaded a clip from social media, or worked with footage that just looks soft and low-resolution, you have probably wondered if there is a way to make it look better. That is exactly what AI video upscaling does.

What is AI Video Upscaling?

AI video upscaling is the process of increasing a video's resolution using artificial intelligence. Unlike traditional upscaling, which simply stretches pixels and results in a blurry image, AI upscaling actually generates new detail. The model analyzes each frame of your video and reconstructs textures like hair, skin, fabric, and edges at a higher resolution.

Think of it like this: traditional upscaling is like zooming in on a photo and seeing it get blurry. AI upscaling is like zooming in and the photo gets sharper. The AI model has learned from millions of images what fine detail should look like, so it fills in realistic information that was not in the original footage.

Why Upscale Your Videos?

There are several practical reasons to upscale video with AI:

  • Old footage recovery -- Videos from older phones, cameras, or screen recordings can be enhanced to modern quality.
  • Social media content -- Low-resolution clips downloaded from platforms often lose quality. Upscaling restores that sharpness.
  • Professional projects -- If you need 4K footage but your source is 720p or 1080p, AI upscaling bridges that gap without reshooting.
  • Better viewing on large screens -- A 720p video looks fine on a phone but terrible on a 4K TV. Upscaling makes it watchable on any display.

How Does Our AI Video Upscaler Work?

UpscaleVideoAI uses a state-of-the-art AI model called LTX-2 19B, specifically designed for video upscaling. Here is how the process works:

  1. Upload your video -- Drop any MP4, MOV, or WebM file up to 10 minutes long.
  2. Choose your target resolution -- Select 1080p, 2K, or 4K depending on your needs.
  3. AI processes every frame -- The model analyzes motion, textures, and edges across every frame of your video.
  4. Download the result -- Get your upscaled video with genuinely sharper detail, not just larger pixels.

The AI is motion-aware, meaning it understands how objects move between frames. This prevents the flickering and ghosting artifacts that cheaper upscaling tools produce. The result is a video that looks like it was originally shot at the higher resolution.

1080p vs 2K vs 4K: Which Should You Choose?

The right resolution depends on your use case:

  • 1080p (Full HD) -- Great for social media, web content, and general viewing. Uses the fewest credits. Best for videos that are currently below 1080p.
  • 2K (2560px) -- A solid middle ground for editing projects, presentations, and larger displays. Uses 2x the credits of 1080p.
  • 4K (3840px) -- Maximum quality for professional work, large screen viewing, and archival purposes. Uses 3x the credits of 1080p but delivers the most impressive results.

What Makes UpscaleVideoAI Different?

There are plenty of tools that claim to upscale video online, but most of them just apply basic sharpening filters or use outdated models. Here is what sets us apart:

  • Real AI detail reconstruction -- We use a 19-billion parameter model specifically trained for video.
  • Temporal consistency -- Our model processes frames with awareness of motion, preventing flicker.
  • Natural results -- No plastic or overprocessed look. The output looks like real, higher-resolution footage.
  • Simple pricing -- Credits based on video length and resolution. No confusing tiers or hidden fees.

How Much Does It Cost to Upscale a Video?

Our pricing is straightforward. 1 credit covers 15 seconds of video at 1080p. Higher resolutions use more credits: 2K costs 2 credits per 15 seconds, and 4K costs 3 credits per 15 seconds.

You can buy individual credits at $5 each, or subscribe for $25/month to get 10 credits with automatic monthly renewal. Purchased credits never expire.

Tips for Best Results

  • Start with the best source you have -- AI upscaling enhances what is there. A cleaner source gives better results.
  • Avoid heavily compressed videos -- Extreme compression artifacts can be harder for the AI to clean up.
  • Try 1080p first -- If you are unsure, start with 1080p to preview the quality before committing to 4K.
  • Use for the right content -- AI upscaling works best on real-world footage. Screen recordings and text-heavy content may not benefit as much.
