Simple x264/x265 Launcher

Simple x264/x265 Launcher is a lightweight, open-source graphical user interface (GUI) designed specifically for encoding videos using the x264 (H.264/AVC) and x265 (H.265/HEVC) encoder libraries. Developed by an independent developer known as lordmulder, it serves as a minimalist, user-friendly front-end for individuals who want high-quality video encoding without dealing with complex command-line interfaces. Key Features

Dedicated Encoding Focus: Unlike bloated multi-tools, it specializes entirely in fine-tuning x264 and x265 compression workflows.

Frameserver Support: It integrates seamlessly with the 64-bit versions of AviSynth and VapourSynth frameservers, allowing you to preprocess, filter, and script videos before encoding.

Batch Processing: Features a task management interface that lets you queue up, pause, start, or abort multiple video conversions in sequence.

Built-in Presets & Tuning: Includes optimization profiles (e.g., baseline, main, high) and target tuning effects like animation, film, grain, and still images to tweak visual output.

Format Flexibility: Accepts raw YUV streams alongside container formats like MKV, MP4, AVI, and FLV. Portability and Independence

Zero Installation: The application runs completely portable. You simply extract the ZIP archive from download directories like Free-Codecs or its official GitHub page and run it.

Self-Contained Design: It requires no external runtime dependencies like .NET or Java. The required Qt graphical DLLs and core encoding binaries come fully bundled.

USB-Friendly Portable Mode: Renaming the main executable file to x264_launcher_portable.exe forces the program to save all of its configuration files directly inside its own folder rather than the user’s hidden system directories. Underlying Framework & Licensing

C++ and Qt: The interface is built on the Qt cross-platform framework and coded in C++.

Open Source: The entire package is distributed as free software under the GNU General Public License (GPLv2). You can access its public source files directly on the Simple x264/x265 Launcher GitHub Repository.
