Top 4 AI Video Upscaling Open-Source Software in 2024

Many older videos may have been recorded at lower resolutions and may not look as good when played back on modern high-resolution displays. Open source video upscaler can be used to improve the appearance of these videos.

As technology evolves, playing older videos on newer devices can be challenging. Tools like HitPaw Video Enhancer and AI upscaling open-source solutions can preserve these videos by enhancing their quality for modern displays. Let’s explore open-source video upscaling in detail.

Part 1. What is Open Source Video Upscaler?

Open-source AI upscaling refers to the use of open-source software and libraries to perform AI-based video upscaling. These Open-source tools and libraries allow developers to access and modify the source code, making it possible to customize the upscaling process to suit their specific needs.

One of the main advantages of open-source AI upscaling is that it allows developers to build and experiment with their own models rather than being limited to pre-trained models provided by commercial software vendors.

The main drawback of open-source AI upscaling is often limited user support and documentation compared to video enhancement software, requiring higher technical proficiency and potentially encountering quality inconsistencies.

Part 2. Popular 4 Video AI Upsacle Open Source Tools to Enhance Video Quality

1. Video2X-Upsale Video Pytnon AI

Video2X is a Python-based open source video upscaler. It is a free software to upscale videod and is designed to support various types of videos, including anime and live-action, and it uses multiple algorithms to achieve the best possible results.

Video2X User Barrier:

Technical Requirements: Basic programming knowledge required, familiar with Python and command-line operations.
Hardware Requirements: Strong GPU recommended, especially NVIDIA graphics cards, for faster processing.
Operational Complexity: Primarily command-line based, no GUI, setup and configuration can be challenging.

For common usage, you can choose a easier AI video quality upscaler without any tech knowledge.

2. Waifu2x

Waifu2x is an image upscaler 8k free that uses convolutional neural networks and also support video upscaling. It is based on the same technology used in the open source ai video enhancer, waifu2x-caffe. It's a command-line interface that can be integrated into other programs. Suitable for anime enhancement.

Pros

Exceptional at reducing noise and artifacts in anime-style images
Provides options for noise reduction and upscaling factors
Available as both online and downloadable versions

Cons

Slower processing speed compared to some alternatives
May struggle with detailed textures in non-anime images
Can produce overly smooth results in certain cases

3. ESRGAN

Enhanced Super-Resolution Generative Adversarial Networks (ESRGAN) is a neural network-based open source video AI enhancer that is trained to improve the quality of images and videos. It's a powerful model that can be fine-tuned to suit the task and the dataset.

Video2X User Barrier:

Technical Requirements: Requires some programming and deep learning knowledge, primarily Python-based, with dependencies such as PyTorch to be installed and configured.
Hardware Requirements: High-performance GPU (e.g., NVIDIA).
Operational Complexity: No official GUI, fully command-line driven, configuration and execution require technical knowledge.

For common usage, you can choose a easier AI video quality upscaler without any tech knowledge.

4. Anime4K

Anime4K is an open-source AI upscaling tool that is specifically designed to upscale anime videos. It is based on the kernel convolution neural network. It uses a two-stage algorithm that can achieve high-quality results on a wide range of anime videos.

Pros

Designed specifically for anime-style images with good preservation of sharp lines
Lightweight and fast processing
Can run effectively on lower-spec hardware

Cons

Limited effectiveness on non-anime images
May oversharpen or introduce artifacts in certain scenarios
Less flexibility in adjusting processing parameters compared to other tools
