Part 4. FAQs of Video Upscaling GitHub

Q1. How does video2x work?

A1. Unlike traditional methods, Video 2x uses deep learning techniques to analyze and extrapolate missing details in low-resolution videos, resulting in improved visual fidelity. It utilizes state-of-the-art AI algorithms, such as convolutional neural networks (CNNs), which are trained on vast amounts of high-resolution video data. During the upscaling process, Video 2x analyzes each frame's content and generates high-resolution versions based on its learned knowledge.

Q2. How does waifu2x work?

A2. Waifu2x is an image scaling and noise reduction program specifically designed for anime-style art and other types of photos. The tool was inspired by the Super-Resolution Convolutional Neural Network (SRCNN). It primarily uses Nvidia CUDA for computing, but there are alternative implementations that support OpenCL and Vulkan. The name "waifu2x" combines the anime slang "waifu," meaning a female character one is attracted to, with "2x," indicating two-times magnification.

Q3. What is TTA upscale?

A3. TTA, or test-time augmentation, mode averages the upscaling results of eight augmented inputs. This mode can reduce several types of artifacts, enhancing the final image quality. However, it's worth noting that TTA mode is approximately 8 times slower than the non-TTA mode.
