Best AI Video Upscalers 2026
A complete comparison of every AI video upscaler worth considering in 2026. Multi-model pipelines, frame interpolation, temporal consistency, pricing, and real-world quality analyzed across seven tools.
Last updated: March 2026
The State of AI Video Upscaling in 2026
AI video upscaling has matured significantly since the early days of basic super-resolution models. In 2026, the best tools combine multiple AI models, enforce temporal consistency across frames, interpolate intermediate frames for smooth slow motion, and automatically analyze content to configure optimal processing. The gap between free and professional tools has grown wider as paid solutions invest in video-specific features that go far beyond simple frame-by-frame image upscaling.
Choosing the right upscaler depends on your specific needs. Are you upscaling video or images? Do you need temporal consistency? Is frame interpolation important? What is your budget? This guide examines every significant AI upscaler available in 2026 and helps you identify the best tool for your workflow.

Clareon
$40/mo or $199 lifetimeBest for: Professional video upscaling with multi-model intelligence
Clareon earns the top spot through its combination of multi-model pipeline, AI content analysis, temporal consistency, and frame interpolation at a price $100 below its closest paid competitor. The AI agent system automatically analyzes your content and configures the optimal processing chain, routing different image regions to specialized models for faces, textures, and edges. The three-panel preview interface provides real-time comparison between original, processed, and final output.
Frame interpolation generates smooth intermediate frames from AI motion estimation, turning 24fps footage into 60fps or 120fps output. Temporal consistency enforcement prevents the frame-to-frame flickering that plagues per-frame upscaling tools. Batch processing handles video queues efficiently with GPU acceleration. The $199 lifetime license provides unlimited processing without ongoing subscription costs.
- Pros: Multi-model AI pipeline, AI content analysis, temporal consistency, frame interpolation, face enhancement, 3-panel preview, $199 lifetime
- Cons: Windows only, requires capable GPU, newer product (less community)
Topaz Video AI
$299 lifetimeBest for: Established video enhancement with extensive model library
Topaz Video AI is the most established paid video upscaler with years of development and a large, active user community. The model library is extensive, with options optimized for different content types including live action, animation, archival footage, and screen recordings. Temporal consistency, frame interpolation, deinterlacing, and stabilization are all built in. The $299 lifetime price is $100 more than Clareon, and the lack of multi-model pipeline and AI content analysis means manual model selection is required. Processing speed can be slow on resource-intensive models.
- Pros: Established product, extensive models, temporal consistency, deinterlacing, stabilization, large community
- Cons: $100 more than Clareon, no multi-model pipeline, manual model selection, can be slow
Upscayl
Free (open source)Best for: Free image upscaling with GPU acceleration
Upscayl is the best free upscaler for single images. The GUI is clean, GPU acceleration via Vulkan is fast, and the model selection provides options for different content types. For casual image upscaling, Upscayl is hard to beat at zero cost. Video support is limited to basic frame-by-frame processing through community scripts, without temporal consistency or frame interpolation. For professional video work, the lack of temporal consistency creates visible flicker that disqualifies it from serious use.
- Pros: Free, open source, GPU-accelerated, clean GUI, cross-platform, multiple models
- Cons: No video pipeline, no temporal consistency, no frame interpolation, no face enhancement
Gigapixel AI
$99.99 lifetimeBest for: Image-only upscaling with face recovery
Gigapixel AI from Topaz Labs focuses exclusively on still image upscaling with strong face recovery capabilities. For photographers, print professionals, and anyone who needs to upscale images for large-format output, Gigapixel delivers consistently excellent results. The dedicated face model recovers remarkable detail in portraits. No video processing is available, making it a single-purpose tool. At $99.99, it is well-priced for its specific use case.
- Pros: Excellent face recovery, image-optimized, good for print, established product
- Cons: Images only, no video, no frame interpolation, no temporal features
Video2X
Free (open source)Best for: Free video upscaling with engine flexibility
Video2X is an open-source framework that handles video frame extraction, upscaling via multiple AI backends, and reassembly. It supports waifu2x, Real-ESRGAN, and SRMD as processing engines. For technical users comfortable with command-line tools, Video2X provides free video upscaling with more engine flexibility than Upscayl. The lack of temporal consistency, GUI, and automatic configuration limit its appeal for professional or non-technical use.
- Pros: Free, multiple AI engines, video support, open source, configurable
- Cons: CLI only, no temporal consistency, no GUI, manual configuration, slow
Real-ESRGAN
Free (open source)Best for: Image upscaling model with community support
Real-ESRGAN is the AI model that powers many upscaling tools including Upscayl and some Video2X configurations. Using it directly via command line gives more control over parameters and access to the latest model versions. For developers integrating upscaling into custom pipelines, Real-ESRGAN is the go-to model. For end users who want a GUI, tools built on top of Real-ESRGAN (like Upscayl or Clareon) are more practical. Images only; video requires external scripting.
- Pros: Free, excellent image quality, widely supported, community models, developer-friendly
- Cons: CLI only, images only, no video pipeline, technical setup required
Key Factors for Choosing an Upscaler
Temporal Consistency (Video Only)
If you upscale video, temporal consistency is the single most important feature. Without it, fine details shimmer and flicker between frames, producing an obviously processed look. Only Clareon and Topaz Video AI provide proper temporal consistency enforcement. Free tools process each frame independently, which is acceptable for images but problematic for video.
Multi-Model Processing
Different content types benefit from different AI models. Faces, textures, edges, and smooth gradients each have optimal processing approaches. Clareon's multi-model pipeline automatically routes content to the best model for each region. Other tools apply a single model uniformly, which means compromises in quality for at least some content types in every frame.
Frame Interpolation
If you need smooth slow motion or want to increase the frame rate of your footage, frame interpolation is essential. Only Clareon and Topaz offer this capability. Free tools output at the same frame rate as the input, with no ability to generate intermediate frames.
Price vs Quality
Free tools (Upscayl, Real-ESRGAN, Video2X) provide impressive quality for images and basic video. Paid tools (Clareon at $199, Topaz at $299, Gigapixel at $99.99) add professional video features that free tools lack. The value proposition depends on whether you process video professionally. For image-only use, free tools are sufficient. For professional video, the paid tools save hours of manual artifact correction and deliver significantly better output quality.
