Small and fast wrapper for FFmpeg.

Heavily vibe coded. Expect issues.

• Editing:
  • Trim
  • Crop
  • Rotate
  • Flip
  • Resize
  • Specific audio track export, or mix all tracks into one
  • Custom FFmpeg command — the final command is shown and fully editable, and exactly that text is what runs
• Environment:
  • Multi-track audio timeline
  • Presets (edit, import, export)
  • Hotkeys

Input: anything FFmpeg and mpv can read (MP4, MOV, AVI, MKV, WEBM, FLV, WMV, M4V, ...)

Output Codecs:

• Video: H.264, HEVC, VP8, VP9, AV1, ProRes, DNxHD, FFV1, and more (plus hardware encoders)
• Audio: AAC, MP3, Opus, Vorbis, AC-3, FLAC, ALAC, PCM

• FFmpeg + FFprobe — found next to the program first, then in PATH (or set the paths in File → Settings).
• Linux: libmpv2 (sudo apt install libmpv2 · sudo pacman -S mpv · sudo dnf install mpv-libs).
• Windows: nothing else if you use the zip that includes libmpv-2.dll (and FFmpeg if it was bundled).

• Download the .AppImage from the release page
• Allow it to execute: Properties -> Permissions -> Execute, or chmod +x ./FFcut-*.AppImage

It is recommended to use the Gear Lever application for any AppImage installations

• Download ffcut-linux-x86_64.tar.gz from the release page
• Unpack it wherever you like and run ./AppRun

Prerequisites

• Rust (https://rustup.rs)
• libmpv headers: sudo apt install libmpv-dev pkg-config · sudo pacman -S mpv · sudo dnf install mpv-devel
• FFmpeg (to run it)

git clone https://github.com/woysful/FFcut.git
cd ./FFcut
./build-linux.sh                    # -> dist/FFcut-<version>-x86_64.AppImage and dist/ffcut-linux-x86_64.tar.gz
BUNDLE_FFMPEG=1 ./build-linux.sh    # also put ffmpeg/ffprobe from this machine inside

For a quick run without packaging: cargo run --release -p ffcut-app.

Dragging files into the window does not work on native Wayland (the windowing library, winit, has no support for it yet). Run through XWayland instead: File → Settings → Display server → X11, or ffcut --x11, or FFCUT_DISPLAY=x11. --wayland switches back.

Prerequisites

• FFmpeg — download FFmpeg binaries and place ffmpeg.exe and ffprobe.exe in C:\Windows\ or next to ffcut.exe, OR put them anywhere and add that folder to PATH (skip this if your zip already contains them)

• Download FFcut-<version>-windows-x64.zip from the release page
• Unzip it wherever you like and run ffcut.exe

Prerequisites

• Rust with the MSVC toolchain (Visual Studio Build Tools)
• libmpv dev package (e.g. mpv-dev-x86_64-*.7z from shinchiro builds): a folder with mpv.lib and mpv-2.dll

git clone https://github.com/woysful/FFcut.git
cd FFcut
set MPV_DIR=C:\libmpv
set FFMPEG_DIR=C:\ffmpeg\bin
build-windows.bat

FFMPEG_DIR is optional (it bundles ffmpeg/ffprobe into the zip). Result: dist\FFcut-windows-x64.zip.

• crates/ffcut-core — all logic without UI: model (export settings), builder (settings → ffmpeg argv), cmdline (argv ⇄ editable text), probe (ffprobe), run (runs exactly the argv you see: progress, cancel, cleanup). Tested, including against real ffmpeg.
• crates/ffcut-app — the UI (egui + libmpv): player, app, update, ui/.
• Tests: cargo test --workspace (needs ffmpeg in PATH).
• The version lives in one place: [workspace.package] in the root Cargo.toml. Release = bump it, build, publish a GitHub Release tagged v<version>.
• Debug env: FFCUT_DEBUG=1, FFCUT_MPV_LOG=file, FFCUT_NO_AUDIO=1, FFCUT_MPV_DR=auto|yes, FFCUT_DISPLAY=x11|wayland, FFCUT_UPDATE_URL=<url>, FFCUT_NO_UPDATE=1.
• Fonts: Manrope and JetBrains Mono (OFL), embedded from crates/ffcut-app/assets/fonts.

Main principle: on export FFcut runs exactly the text in the command field. Nothing is filtered or reinterpreted.
