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 changes and video formats evolve, it may become difficult to play older videos on newer devices. AI upscaling open-source tools can be used to preserve these videos by making them compatible with modern displays. Let’s take a look at what exactly is open source video upscaling.

Part 1. What is Open-Source AI Upscaling?

Open-source AI upscaling refers to the use of open-source software and libraries to perform AI-based video upscaling. Unlike video enhancement software needing a stable network and processor to operate, 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.

Here's how to use ESRGAN to upscale a video:

  • Step 1.To use the online video upscaler, you'll need to have Python, PyTorch, and CUDA (if you're using a GPU) installed on your computer. Additionally, you will need to install some other python packages such as numpy, opencv, and more.

  • Step 2.You can download the ESRGAN package from the GitHub repository. After downloading the package, you'll need to extract the files to a location on your computer.

  • Step 3.Once you have the package installed, you can use command-line interface to run ESRGAN on your desired video. You will need to load the model and set the parameters accordingly. You can either use the pre-trained models that come with the package or you can train your own model on a dataset that is similar to your video.

  • Step 4.Depending on the size of the video and the processing power of your computer, this step may take some time. ESRGAN will process the video, upscaling its resolution and saving the output to the specified file.

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.
