6.0.0

This is the official release of Video2X version 6.0.0.

TL;DR: Version 6.0.0 is a complete rewrite of the Video2X project in C/C++, featuring a faster, more efficient architecture, cross-platform support, vastly improved output quality, and a new GUI and installer for easy setup on Windows.

Note

October 29, 2024: The Windows installer has been updated to automatically install the VC++ Runtime if required and to check for Vulkan support, warning the user if the Vulkan runtime is missing.

Complete Summary of Changes in 6.0.0

Version 6.0.0 is a complete rewrite of this project in C/C++. It:

• genuinely works this time, with much less hassle compared to the 5.0.0 beta;
• is blazing fast, thanks to the new optimized pipeline and the efficiency of C/C++;
• is cross-platform, available now for both Windows and Linux;
• offers significantly better output quality with Anime4K v4 and RealESRGAN;
• supports Anime4K v4 and all custom MPV-compatible GLSL shaders;
• includes support for RealESRGAN (all three models) via ncnn and Vulkan;
• requires zero additional disk space during processing, just space for the final output; and
• exports a standard C function for easy integration into other projects! (documentations are on the way)

The graphical user interface currently supports the following languages:

• English (United States)
• 简体中文（中国）
• 日本語（日本）
• Português (Portugal)

Why the 5.0.0 branch was abandoned:

• Wrapped C++ libraries for Python were too complex to build for cross-platform distribution.
• Certain wrapped C++ libraries exhibited unexpected behaviors.
• Running FFmpeg through commands and piping data via stdin/stdout proved inefficient.
• Native C/C++ binaries are significantly smaller and more efficient, leveraging the inherent speed of machine code, compiler optimizations, and link-time optimization.

All Notable Changes From 6.0.0-beta.5

• feat: added all Anime4K v4 modes (A, B, C, A+A, B+B, C+A, GAN)
• fix: fixed the issue where custom GLSL shader paths are formatted incorrectly on Windows
• fix: fixed the issue where the output video has a different advertised frame rate than the original video
• fix: fixed missing and incorrect command line arguments

6.0.0-beta.5

Without major issues and bugs, this should be the last beta build before the official release of 6.0.0.

All Notable Changes From 6.0.0-beta.4

• feat: added more modes for Anime4K v4 (A, B, C, A+A, B+B, C+A)
• feat: added the about dialog and a report bugs link
• fix: fixed the issue where the user can select an invalid scaling ratio for the selected RealESRGAN model
• fix: fixed the bug where non-English systems cannot switch to the English locale

libplacebo now comes with all Anime4K v4 modes:

A short description for each mode is available in the tooltip:
