Open Source Rust Video Editing Software

Concat is a free and open-source desktop video editor positioned as a local alternative to subscription-based editors such as CapCut. It uses a native Rust engine and performs editing entirely on the user’s machine. Projects can contain multiple tracks and timelines for more complex compositions. Core editing tools include splitting, trimming, merging, transitions, and playback-speed adjustment. Offline features include automatic captions, local text-to-speech voices, voice processing, titles, and styled text. Templates allow reusable edit structures to be applied across projects. Concat is currently in beta and targets macOS, Windows, and Linux with a multilingual interface.

FilmCraft is an open-source nonlinear video editor written from scratch in Rust as a clean-room reimplementation of familiar Premiere Pro workflows. It provides source and program monitors, bins, multitrack timelines, workspaces, effects, color tools, titles, audio, and export functions. The project includes its own implementations of codecs and containers such as H.264, HEVC, ProRes, AAC, VP9, Opus, MP4, and Matroska. A GPU compositor works in linear light, while exact integer time math prevents edit drift. Every editing action is exposed as a command, allowing automation through a CLI, JSON control server, or MCP. Native builds target macOS, Windows, and Linux, while the same engine can also run through WebAssembly. FilmCraft is under active development and does not yet claim complete production parity.

REVE (Real-ESRGAN Video Enhance) is a small, fast application written in Rust that is used for upscaling animated video content. It utilizes Real-ESRGAN-can-Vulkan, FFmpeg and MediaInfo under the hood. REVE employs a segment-based approach to video upscaling, allowing it to simultaneously upscale and encode videos. This results in a notable enhancement in performance and enables the feature of reusability. You can download Windows executable file for Intel/AMD/Nvidia GPU. This executable file is portable and includes all the binaries and models required. No CUDA or PyTorch environment is needed.

An attempt to write Anime4K in Rust. Anime4K is a state-of-the-art*, open-source, high-quality real-time anime upscaling algorithm that can be implemented in any programming language.

Free FPS is an open‑source desktop app and scripts to change a video file frame rate (FPS) using FFmpeg. Unlike video editors, it does not add effects or alter content - it only adjusts playback speed and, if needed, re-encodes audio as well. Useful if you work with multiple videos shot at different frame rates that cannot be combined or edited without interpolation or frame loss. Also doubles as a fast video compressor: keep the original FPS and raise compression (e.g., higher CRF or lower bitrate) to reduce file size. What it does: Changes video FPS via FFmpeg. Keeps or re‑encodes audio if requested. No effects, no content edits. Writes results to a separate output folder by default. Also doubles as a fast video compressor: keep the original FPS and raise compression (e.g., higher CRF or lower bitrate) to reduce file size. Important: The program is intended for users who understand what FPS conversion does. Changing the frame rate affects the speed and duration of the video
