Video2X Review & Tutorial (2026): How to Upscale Videos for Free

When I first started looking for a free AI video upscaler, Video2X was the name that kept coming up. After spending quite a bit of time testing it, I decided to write this Video2X tutorial based on my real experience. This article serves as an in-depth, hands-on Video2X review and a complete Video2X tutorial. I will cover everything from downloading the software safely and navigating the GUI, to mastering filter selection and finding the best settings. 

Introduction to Video2X

What is Video2X

Video2x is a free, open-source AI-based video upscaling tool released under the AGPL-3.0 license, designed to enhance low-resolution videos, animations, and GIFs to high resolution (up to 4K). Unlike traditional video stretching software, Vide2X uses FFmpeg to extract a video frame by frame. It then applies advanced deep learning models—such as Waifu2X, Anime4K, and Real-ESRGANal—to denoise and upscale each individual frame before merging them back into a high-resolution video.

Key Features of Video2X

• AI-Powered Upscaling: Video2X leverages models like Real‑ESRGAN, Waifu2x, Anime4K, and SRMD to enhance resolution and detail.
• Frame Interpolation: Video 2X uses AI, such as the RIFE (Real-Time Intermediate Flow Estimation) algorithm, to increase frame rates for smoother playback.
• GPU Acceleration: Accelerated via Vulkan/ncnn backends; performance scales with modern GPUs.
• GUI and CLI: Choose a user-friendly Qt GUI or flexible command line.
• Wide Format Compatibility: Works with videos, images, and GIFs via FFmpeg integration.

Video2X Core Engines

Video2X is a powerful framework, but its results depend entirely on the AI engine you select. You should understand which built-in model fits your specific video type:

1. Real-ESRGAN (Best for Real-Life Footage): The gold standard for general-purpose upscaling. It excels at restoring textures in real-world videos, home movies, and cinematic content.
2. Anime4K (Best for Speed): Not a heavy AI model, but a high-speed shader. It’s the fastest way to sharpen anime lines during playback or quick exports, though it lacks the "hallucination" detail of deep learning models.
3. Waifu2x / Real-CUGAN (Best for Anime): Specifically trained for 2D illustration. These are the best settings for removing compression artifacts from old anime without losing the hand-drawn feel.

Video2X Supported Formats

Thanks to its FFmpeg backend, Video2X supports nearly all mainstream media. Whether you are performing a video2x upscale or batch-processing images, here is the compatibility breakdown:

• Video Formats: MP4, MKV, AVI, MOV, WEBM, FLV, WMV, TS, M4V, VOB.
• Image Formats: JPG/JPEG, PNG, BMP, TIFF, WebP.
• Animation: Fully supports GIF upscaling and enhancement.
• Audio: Preserves original audio tracks (AAC, MP3, Flac, etc.) during the upscaling process.
• Output Codecs: H.264 (AVC), H.265 (HEVC), and VP9.

Pro Tip: For the video2x best settings, I recommend using MP4 (H.264) for output to ensure the best balance between high-quality results and device compatibility.

System Requirements & OS Support

Is Video2X Free

Video2X is a free AI video upscaler. It is released as open‑source under the AGPL‑3.0 license, allowing you to download, modify, and redistribute it. Official builds are available on GitHub for Windows and Linux; macOS is not officially supported and typically requires workarounds.

What Kind of Videos Work Best with Video2X

Video2X is suitable for various types of videos. Here are the key types of videos Video2X is well-suited for:

• Anime and Cartoons:

Since Video2X uses the algorithm of waifu2x. which was originally designed for anime-style images, so Video2X performs well when handling sharp edges and flat color regions, common in animation.

At the same time, I recommend you a Video2X alternative, which also performs well in anime video enhancement. UniFab is an excellent anime upscaler.

• Old or Low-Resolution Videos:

It is useful for upscaling older videos that were originally recorded in lower resolutions, such as 480p or 720p. This makes it a good choice for improving the quality of older movies, TV shows, or home videos..

• Game Footage:

Video2X can upscale video game recordings or older game trailers that may have been recorded in lower resolutions. It works especially well with pixel art games, which have a style similar to anime.

• Movies and TV Shows:

Video2X can also make live-action movies and TV shows look better, even though the results might be different depending on how complicated the scenes are and how good the original video was.

• YouTube Videos and Web Videos:

Many videos available online may not be in high definition, especially older YouTube videos. Video2X can upscale these, enhancing their clarity for larger screen viewing.

• GIFs and Small Videos:

If you have GIFs or short videos that were squished or saved in a bad way, Video2X can make them look better without losing much quality.
