Are you looking for a way to upscale your video to 4K and beyond? Look no further. In this article, we'll show you how to use AI video enhancers to improve the quality of your footage from 720p to 4K.
But with so many AI tools on the market today, which ones deliver really crisp results? Keep reading to find out.
An AI video upscaler is an online tool that increases the resolution of the video by adding new pixels around existing ones, essentially adding detail that wasn’t there to every single frame on the video.
As a result, you can double, triple, quadruple or sometimes even quintuple the resolution of a video clip.
Examples of AI video upscalers include Overchat AI, Vmake, HitPaw VikPea, VEED, and Topaz Video AI, though there are many others.
This depends on the type of upscaler. There are two main approaches: traditional and AI-powered. Let's see how each works:
1️⃣ How do traditional video upscalers work? Traditional upscalers increase resolution by interpolating between existing pixels using basic algorithms like bicubic or bilinear scaling. This makes the canvas of the video larger, but also results in blurry, soft footage that lacks detail.
2️⃣ How do AI video upscalers work? AI-powered tools analyze each frame using neural networks trained on millions of video clips. They generate new pixel data and reconstruct missing detail — textures, edges, faces — resulting in a sharper, more natural-looking output.
Here's how the top 5 AI video upscalers compare across key features and pricing:

HitPaw VikPea (formerly HitPaw Video Enhancer) is a desktop-based AI video enhancement suite that goes beyond upscaling. It can increase video resolution up to 8K and includes specialized AI models for different content types:
It also offers video stabilization, frame interpolation for smooth slow-motion, and SDR-to-HDR conversion. HitPaw VikPea is available on Windows, macOS, iOS, Android, and as a web-based tool, making it one of the most versatile options on the market.
HitPaw VikPea Pros:
✅ Upscaling up to 8K resolution
✅ Batch processing
✅ Video stabilization and frame interpolation
✅ SDR-to-HDR
HitPaw VikPea Cons:
❌ Expensive — starts at $42.99/month
❌ Requires powerful hardware (dedicated GPU recommended)
❌ Long processing times for high-res upscaling
Pricing: Standard plan from $42.99/month (Windows) or $69.99/month (Mac). Annual plans: $99.99/year (Windows Standard). Perpetual license: $349.99 one-time. Free trial available with watermarked preview.
VEED is an all-in-one browser-based video editing platform that includes video enhancement as part of its broader toolkit. While it's not a dedicated upscaler, it offers a convenient way to improve video quality within a full editing workflow.
Where VEED shines is convenience: if you need to enhance a video and then immediately add subtitles, trim footage, apply filters, or resize for social media — you can do it all without switching tools.
VEED Pros:
✅ Full video editing suite in the browser
✅ AI-powered subtitles, background removal, noise cleanup
✅ Exports up to 4K on paid plans
VEED Cons:
❌ Free plan limited to 720p with watermark
❌ Performance issues with large files
❌ Higher-tier plans are expensive
Pricing: Free plan lets you upscale to 720p and export with watermarks. Upgrade to lite for $19/month and upscale to 1080p without watermarks Pro costs $49/month and comes with 4K export, and advanced AI tools.
Topaz Video AI is the industry gold standard for professional video upscaling. Developed by Topaz Labs, this desktop software uses over 13 specialized AI models — each trained exclusively on video clips — to deliver cinema-grade enhancement results.
The software includes dedicated models for different tasks: Proteus for general enhancement, Nyx for noise reduction, Artemis for fast processing, Gaia for CG content, Iris for face recovery, and several others. It also features frame interpolation (via Chronos and Apollo models) for creating smooth slow motion, video stabilization, deinterlacing for legacy footage, and SDR-to-HDR conversion.
Topaz Video AI processes everything locally on your computer, so your files never leave your machine — a critical advantage for privacy-conscious professionals. However, this requires a powerful GPU for reasonable processing speeds.
Topaz Video AI Pros:
✅ Best-in-class output quality
✅ Complete privacy — local processing only
✅ Up to 8K upscaling
✅ Frame interpolation for smooth slow motion
✅ Plugin support for Premiere Pro, DaVinci Resolve
✅ Batch processing
Topaz Video AI Cons:
❌ Subscription-only since October 2025 (from $25/month)
❌ Requires powerful GPU (16GB+ RAM recommended)
❌ Steep learning curve
Pricing: This app switched to a subscription model in October 2025. Here’s how much it costs:
There’s a free trial available with watermarked output.
An AI video upscaler is software that uses artificial intelligence to make videos look better. In short, the tool looks at each frame and adds pixels where they would have gone in a video of a target resolution — which, essentially, adds new details.
AI video upscaling uses neural networks trained on millions of video clips. The AI looks at patterns across images, identifies different types of content (like faces, textures, and motion), and creates new pixels that match the style and detail of the existing images — while maintaining temporal consistency between frames to avoid flickering.
Video upscaling specifically increases resolution (for example, turning 720p input into a 4K output) by generating new pixel data. Video enhancement is a more general term. It refers to improving the overall quality of a video by making adjustments such as brightness, contrast, color correction, noise reduction, and sharpening. These adjustments don't necessarily involve changing the resolution.
