XDA’s piece on the RTX Video Super Resolution toggle inside VLC was a reminder of how good real-time, GPU-side upscaling has become for the casual case. The toggle takes a 720p stream from a browser or media player and rebuilds it to fit a 4K panel, and it does it without re-encoding anything. The catch is that the result lives inside the player. The moment a workflow wants the upscaled file on disk, a clip ready for a YouTube upload, or per-clip control over the model and the strength, the conversation moves from the player into a dedicated upscaling app.
We tested 8 of the best apps for video upscaling on Windows, macOS, and Linux. The benchmarks were the boring ones: how each handles old DVD footage (a real-world case), how clean the result is on faces and text (the two failure modes most users notice first), how fast a 5-minute clip turns into a 4K master on a current RTX card, and how much each tool charges.
What to look for in a video upscaling app
- Model variety. A model trained on animation will ruin live-action and vice versa. A useful upscaler offers several.
- Frame-by-frame consistency. Single-frame upscaling produces flicker. Tools that build in temporal coherence (looking at neighbouring frames) hold up better in motion.
- Hardware support. CUDA on Nvidia, ROCm or DirectML on AMD, Metal on Apple Silicon. The speed gap between a tool that uses your GPU and one that does not is roughly 20x.
- Batch processing. Real workflows convert dozens of clips. A queue, a CLI, and clean output naming matter more than any single-clip benchmark.
- Output format control. CRF, bitrate target, container, audio passthrough. A tool that always re-encodes audio is a tool you will not use twice.
- Pricing model. Some of these are one-time purchases, some are subscriptions, and a few are fully free.

The 8 best apps for video upscaling on desktop
1. Topaz Video AI — best for professional live-action work
Topaz Video AI is the current default for studios working on archive restoration. The temporal models (Proteus, Iris, Rhea, Apollo) are trained on real cinema footage and hold up under the cases that destroy weaker upscalers: motion blur on hair, fast pans, low-bitrate DVD sources. The interface lets you stack a denoise, a frame-interpolation, and an upscale model in a single pass, which saves a lot of manual round-tripping.
Where it falls short: The licence is the steepest in this list, and the upgrades to new model bundles are paid in addition to the one-time fee. Render times on an integrated GPU are long. The “Linux” build is technically a Docker image, not a polished native app.
Pricing:
- Free: trial with watermarked output
- Paid: one-time licence with a year of updates, then a paid renewal for additional updates
Platforms: Windows, macOS, Linux (Docker)
Download: topazlabs.com/topaz-video-ai
Bottom line: Pick Topaz Video AI for video upscaling if you are working on archive restoration or any live-action footage where temporal coherence matters and the price tag is justifiable.
2. Video2X — best free pipeline you can script
Video2X is the open-source workhorse most YouTube tutorials end up pointing at. The tool wraps several backend models (Real-ESRGAN, Anime4K, waifu2x) behind a unified CLI and now a usable GUI, splits a clip into frames, runs the chosen model on each, and reassembles the video with the original audio. The CLI is what makes it real: a single bash loop will process an entire folder overnight.
Where it falls short: Setup is more involved than the commercial tools. The GUI is functional rather than polished. Models do not have temporal awareness, which means motion-heavy footage can flicker.
Pricing:
- Free: open source, GPL
- Paid: none
Platforms: Windows, macOS, Linux
Download: github.com/k4yt3x/video2x
Bottom line: Pick Video2X for video upscaling if you are happy to set up a tool that runs from the command line and you want a free pipeline that handles batches.
3. AVCLabs Video Enhancer AI — best polished commercial UI
AVCLabs Video Enhancer AI is the option people land on when they want Topaz-style results in a cleaner interface. The model picker covers general, face-refinement, denoise, colour correction, and frame interpolation, and the queue handles dozens of clips without restarts. The face-refinement model is the one that earns its keep on archive home video.
Where it falls short: Linux is not on the list. The subscription model has crept into newer versions, alongside the one-time licence. Watermarked trial output is hard to assess at low resolution.
Pricing:
- Free: trial with watermarked output
- Paid: subscription or one-time licence
Platforms: Windows, macOS
Download: avclabs.com
Bottom line: Pick AVCLabs for video upscaling if you want commercial results without Topaz’s price and the face-refinement model maps to your source material.
4. DVDFab Video Enhancer AI — best for DVD and Blu-ray restoration
DVDFab Video Enhancer AI is a focused tool inside the broader DVDFab suite, and it is the best option in this list for interlaced sources, PAL/NTSC conversions, and the de-blocking case that real DVD rips need before any upscaler can do useful work. The pipeline keeps the audio untouched and supports the chapter structure that comes out of a DVD ripper.
Where it falls short: The wider DVDFab ecosystem leans hard on bundles, which makes pricing confusing. The model variety is narrower than Topaz or AVCLabs. The UI carries some of the older DVDFab aesthetic.
Pricing:
- Free: trial with limited output length
- Paid: subscription or one-time licence per module
Platforms: Windows, macOS
Download: dvdfab.cn/video-enhancer-ai
Bottom line: Pick DVDFab Video Enhancer AI for video upscaling if you are restoring DVDs or interlaced sources and you want a single pipeline from disc to file.
5. HitPaw VikPea — best beginner-friendly batch tool
HitPaw VikPea (formerly HitPaw Video Enhancer) is the entry point for users who want one-click presets matched to a content type: general, animation, face, low-light. The queue is straightforward, the export defaults are sensible, and the result on stock-quality phone video is decent without any tuning.
Where it falls short: The advanced controls are thin. Frame-interpolation results lag the dedicated tools. The trial limits output length and adds a watermark.
Pricing:
- Free: trial with watermark
- Paid: subscription or one-time licence
Platforms: Windows, macOS
Download: hitpaw.com/video-enhancer.html
Bottom line: Pick HitPaw VikPea for video upscaling if you want a few clean presets and you do not want to tune model parameters.
6. Waifu2x-Extension-GUI — best for anime, illustration, and game capture
Waifu2x-Extension-GUI is the open-source tool the anime community standardised on. The waifu2x and Real-CUGAN models behind it are trained on illustration and animation, which means the result on cel-shaded sources beats every general model in this list. The GUI handles batches and supports CPU, CUDA, and Vulkan backends.
Where it falls short: Live-action footage gets the same waxy look it always does from an anime-trained model. Windows only. The interface is dense, with options that only matter for a few sources.
Pricing:
- Free: open source
- Paid: none
Platforms: Windows
Download: github.com/AaronFeng753/Waifu2x-Extension-GUI
Bottom line: Pick Waifu2x-Extension-GUI for video upscaling if your sources are anime, illustration, or game capture and you want a free GUI.
7. Real-ESRGAN GUI — best photo-grade model under the hood
Real-ESRGAN is the open-source model that quietly powers most of the free upscalers in this list. The standalone GUI builds (several exist; the most maintained one ships through community projects) expose the raw model with minimal layering and produce results that read more like a high-quality photo upscale than a smoothing filter. For clip extracts and short loops it can outperform a commercial tool.
Where it falls short: No temporal awareness, which means motion can flicker. Long clips are slow without a strong GPU. Documentation varies by which GUI build you use.
Pricing:
- Free: open source, BSD
- Paid: none
Platforms: Windows, macOS, Linux
Download: github.com/xinntao/Real-ESRGAN
Bottom line: Pick Real-ESRGAN GUI for video upscaling if you want the model behind half the open-source tools and you are comfortable with a community GUI.
8. Upscayl Video — best cross-platform free GUI
Upscayl Video is the video extension of the popular open-source Upscayl image upscaler, wrapping Real-ESRGAN in a single window that runs the same way on Windows, macOS, and Linux. The interface is the cleanest of the open-source options, and the model picker covers general, animation, and a few sharpening variants. For short clips on Apple Silicon it can be the fastest open-source option.
Where it falls short: Long-form video performance is limited by the underlying model’s lack of temporal coherence. Some of the optional models live behind a paid Pro tier in the bundle.
Pricing:
- Free: open source, AGPL
- Paid: optional Pro models
Platforms: Windows, macOS, Linux
Download: upscayl.org
Bottom line: Pick Upscayl Video for video upscaling if you want a cross-platform GUI that works on a Mac or Linux laptop and you do not want to set up a CLI tool.

- If you only need to upscale a clip extract for a thumbnail or a still: Real-ESRGAN GUI is enough.
FAQ
What is the difference between RTX Video Super Resolution and a desktop upscaler?
RTX Video Super Resolution is a real-time filter that runs inside a video player (browsers, VLC, mpv) and rebuilds the on-screen frame at higher resolution. It never produces a file. Desktop upscalers process the source file, frame by frame, and write a new file that is higher resolution. Real-time filters are great for casual viewing; desktop upscalers are what you want when the upscaled clip needs to live somewhere outside the player.
Will video upscaling work on integrated graphics?
It will run. It will be slow. A 5-minute 1080p clip upscaled to 4K can take an hour on an integrated GPU and a few minutes on a current RTX card. Apple Silicon GPUs sit between the two.
Can I upscale a movie to 4K without losing quality?
You will not get true 4K from a 480p source, no matter the model. The result will look better than naive scaling, but the underlying detail is not there. The closer the source is to the target (1080p to 4K, say), the more believable the result.
Do these tools work for AI-generated video?
Most do. AI-generated content from Sora-style or Runway-style models often comes out at low resolution and benefits from a Real-ESRGAN or Topaz pass. The temporal models (Topaz, AVCLabs) tend to handle the slightly inconsistent generation better than single-frame models.
Are open-source upscalers as good as commercial ones?
For single-frame jobs and short clips, yes — the open-source models like Real-ESRGAN are state of the art for their use case. For long-form video where motion coherence matters, the commercial tools’ temporal models pull ahead by a meaningful margin.
