VIDEO UPSCALER FOR WINDOWS
Upscale Low-Resolution Videos to 4K on Windows
Have a 480p family recording, 720p clip or small screen capture? Start with the AI model, then choose your output. Ultra (Gen AI) provides Original, 2×, 4×, 1080p and 2K choices where supported. Topaz Ultra (Gen AI) offers a selectable 1080p or 4K output. Upscaling can improve apparent detail, but increasing resolution does not recreate the exact original information.
OriginalEnhance softness without changing dimensions
2× / 4×Use model-supported enlargement factors
1080p / 2K / 4KTopaz Ultra offers an explicit 4K export choice
QUALITY ENHANCEMENT OPTIONS
Choose the Right AI Video Enhancement Model for Windows
Use Standard for everyday cleanup, Ultra (Gen AI) for more natural-looking reconstruction, or Topaz Ultra (Gen AI) when you need a supported 4K output and more detailed enhancement.
Standard
Everyday PC fixesFor mildly soft meeting captures, camera clips and short web videos, Standard emphasizes essential video cleanup and straightforward processing. On eligible Windows PCs, Quality Enhancement Standard supports NVIDIA RTX 30-series or later GPU acceleration; exact availability depends on your hardware and selected feature. Do not confuse it with the separate Face Enhancement Standard mode.
Ultra (Gen AI)
Natural-looking generative detailFor compressed recordings or older footage with missing texture, Ultra uses generative processing to produce clearer-looking edges and more coherent detail. Choose Original when keeping dimensions matters, or use supported 2×, 4×, 1080p and 2K outputs. Check fast movement and small on-screen text in Preview before processing a long file.
Topaz Ultra (Gen AI)
4K output for detail-rich clipsUse Topaz Ultra when exporting supported videos at 1080p or 4K and prioritizing fine structures such as product surfaces, buildings and landscapes. It is a premium generative mode; processing time, credits and possible AI-created artifacts depend on source quality and output selection. Choose 4K only if it meaningfully fits your project.
Output settings shown in the desktop interface: Ultra (Gen AI) — Original, 2×, 4×, 1080p, 2K; Topaz Ultra (Gen AI) — 1080p, 4K. Available output and AI credit costs are model- and source-dependent. AI-created texture is an interpretation, not a verified reconstruction of missing information.
Have a Windows PC with an NVIDIA GPU? Compare GPU-accelerated and cloud-powered modes to choose the appropriate processing route. The same model name can mean different processing requirements in Quality versus Face Enhancement.

Apply a specialized fix for the actual problem in your footage: PC recordings, webcam faces, grain and flicker, unsteady movement or a large folder of videos.
UPSCALE VIDEO ON WINDOWS
Improve Low-Quality Gameplay and Screen Recordings
Gameplay captures and repeated MP4 exports can lose fine lines, edges and texture. Try Quality Enhancement on a representative clip, inspect gameplay HUD details and fast movement, then select the output size supported by your model. For more about resolution choices, see the AI video upscaler.
- Check compressed gameplay edges, small text and detailed interfaces in a short preview.
- Use Standard for everyday cleanup or Ultra for more intensive generative enhancement.
- Select Topaz Ultra when supported footage needs a 4K target.
WINDOWS FACE ENHANCEMENT
Enhance Webcam and Interview Faces on Windows
Portraits from older webcams, online interviews and low-light recordings often lose hair strands or facial definition. Face Enhancement Standard offers a local NVIDIA GPU option on compatible RTX 30-series+ Windows PCs; Face Ultra (Gen AI) uses cloud-based reconstruction for another type of result. Anime Enhancement is a separate option for animation and illustrated lines.
- Face Standard: hardware-dependent local processing.
- Face Ultra: cloud generative detail; preview for realistic facial features.
- Anime Enhancement: improve line art without treating it like a real face.
PC RECORDINGS & LOW LIGHT
Reduce Video Noise, Nighttime Grain and Flicker
A webcam shot in a dark office, an over-compressed stream archive or a phone clip shot at night can all look noisy for different reasons. Use General Video Denoise for grain, Night Scene Enhancement for dark footage and De-Flicker for repeated brightness changes. The comparison preview helps you avoid excessive smoothing.
- Denoise reduces distracting speckles and compression-like noise.
- Night Scene and Color tools serve different problems from 4K upscaling.
- Inspect skin, text and textured backgrounds after enhancement.
ACTION & MOTION
Stabilize Shaky Video and Smooth Motion
Shaky handheld shots and choppy action sequences need different fixes from a blurred still image. Video Stabilization aims to reduce camera movement, while Frame Interpolation can create intermediate frames for smoother playback. Video De-Flicker addresses pulsing illumination from problematic lighting.
- Use stabilization when the camera moves unpredictably.
- Choose frame interpolation when cadence—not image resolution—is the problem.
- Output frame rate and quality depend on the source and tool settings.
BATCH VIDEO ENHANCER WINDOWS
Batch Enhance Multiple PC Videos in One Queue
Working through recorded lessons, event footage or video archives? Import multiple supported files or a folder, choose appropriate processing settings and preview a representative result. UniConverter shows estimated AI credit use so you can decide before running the supported Enhance All & Export workflow.
- Add multiple supported files or an entire folder from the Windows desktop.
- Check Preview (3 s) before running longer or higher-resolution jobs.
- Review the queue and destination before exporting selected video tasks.
The samples illustrate possible enhancement outcomes; your Windows footage, selected model and output settings determine the actual result. AI-generated textures should be checked carefully rather than treated as exact original detail.
WINDOWS GPU & PROCESSING
GPU-Accelerated vs. Cloud AI Video Enhancement on Windows
Windows PCs can offer different enhancement paths depending on the model. Check local NVIDIA GPU requirements for eligible Standard modes, or choose supported generative processing for reconstruction and 4K targets.
Have an NVIDIA RTX 30-Series or Newer GPU?
On compatible Windows PCs, Quality Enhancement – Standard, Face Enhancement – Standard, and Anime Enhancement support selected NVIDIA RTX acceleration workflows. The Face Standard path is documented as local GPU processing. Requirements are model-specific.
Best next step: check GPU compatibility, then preview a short sample before committing to a long export.
Need More Reconstructed Detail or 4K Output?
Try Quality Enhancement – Ultra for natural-looking reconstruction and adjustable output choices, or Topaz Ultra for its explicit 4K target. Face Ultra (Gen AI) is a cloud-based portrait option. Some generative tasks require internet access and AI credits.
Best next step: compare faces, lettering and moving textures in the 3-second preview.
Not Sure Which Mode Your PC Supports?
You do not need to assume that every AI feature requires the same graphics card. Start with a mode available in your installation, check the model's requirements and estimated credits, and process one representative clip before building a batch queue.
Best next step: review UniConverter system requirements for your Windows configuration.

FREQUENTLY ASKED QUESTIONS
AI Video Enhancer for Windows FAQs: 4K, GPU and Downloads
01What should I look for in an AI video enhancer for Windows?
Look for the types of defects it can fix, output choices, hardware requirements, previews and batch controls. UniConverter for Windows combines Quality Enhancement, Face Enhancement, denoising, stabilization and frame interpolation. The best model depends on the footage rather than a universal preset.
02How do I enhance video quality on Windows 11 or Windows 10?
Launch UniConverter and open Enhance & Clean Up → Video Enhancer. Import your clip, choose the matching quality mode and output settings, use Preview (3 s), and click Enhance All & Export. See the Windows step-by-step guide.
03Can an AI video upscaler for Windows export 4K?
Yes. Topaz Ultra (Gen AI) provides a 4K target alongside 1080p in the Video Enhancer UI. Ultra (Gen AI) instead offers Original, 2×, 4×, 1080p or 2K choices when supported. A 4× scale factor is not automatically a 4K output file.
04Can I fix a blurry screen recording without making it 4K?
Yes. When available, Ultra (Gen AI) → Original keeps the source dimensions while enhancing visible detail. Upscaling is an optional output choice; it does not guarantee that compressed lettering or lost pixels can be restored exactly.
05Do I need an NVIDIA graphics card to enhance videos on Windows?
Not for every model. On compatible Windows PCs, selected modes—Quality Enhancement Standard, Face Enhancement Standard and Anime Enhancement—support NVIDIA RTX 30-series or later acceleration. Other AI models have their own hardware and network requirements. Consult the technical specifications.
06Which Face Enhancement mode works locally on Windows PCs?
Face Enhancement Standard uses local GPU processing on eligible Windows PCs with RTX 30-series or newer NVIDIA graphics and compatible settings. Face Ultra (Gen AI) is a cloud-based generative option. These are not the same as the similarly named Quality Enhancement modes.
07Is the Windows AI video enhancer completely offline?
No blanket offline guarantee applies to every mode. Local GPU processing is available for supported tasks, but certain generative models—such as Face Ultra—depend on online resources. Account checks and AI credits may also be needed.
08Can I batch enhance several videos on a Windows PC?
Yes. You can add supported files or folders, select the desired enhancement workflow and review preview results and estimated AI credits before running Enhance All & Export. Verify model limits for longer or larger inputs.
09What is the difference between an AI video enhancer and a Windows video upscaler?
A video upscaler changes the output pixel dimensions. A video enhancer can also address grain, faces, color, flicker and motion. UniConverter offers both approaches; use an Original output setting where available if you want an improvement without resizing.
10Is UniConverter AI Video Enhancer free for Windows?
UniConverter is available as a free Windows download and trial. Higher-resolution processing and selected AI models may require credits or paid access. For a no-install option, try the online AI video enhancer under its current free limits.
11Which formats can I open in the Windows Video Enhancer?
The desktop Video Enhancer interface lists MP4, MKV, AVI, MOV and MPG. Input support, length, file size and output options can vary by model. For unusual files, test one clip before building a large queue.
12Is AI Video Enhancer for Windows available for Mac?
The two desktop platforms share many enhancement concepts, but interface paths and hardware choices can differ. For macOS-specific guidance, go to AI Video Enhancer for Mac rather than following Windows GPU instructions.
