VIDEO RUNTIME
Install FFmpeg for Flixlar
Flixlar uses FFmpeg and FFprobe for MP4 export, burned-in captions and video metadata detection.
About the runtime -
FFPMEG
Flixlar can open and edit some files without the video runtime, but MP4 export, high-quality subtitle rendering and detailed video detection require FFmpeg and FFprobe.
Install options
Automatic install
Recommended for most users. Open Flixlar → Dependencies → Install runtime.
This installs a local Flixlar runtime inside the app data folder and keeps it managed by the app.
Global FFmpeg install
Recommended if you already use other video tools and want one shared FFmpeg installation.
Shared installations can save disk space and be used by multiple apps.
Custom runtime path
Advanced option — use this when FFmpeg/FFprobe are installed in a non-standard location or when automatic detection fails.
Point Flixlar to the runtime bin folder containing the binaries.
Platform: global install
macOS (Homebrew)
Install via Homebrew:
brew install ffmpegIf Homebrew is not detected by Flixlar, use the custom runtime path below.
Windows
Download the official FFmpeg builds from the FFmpeg website. Make sure you have ffmpeg.exe and ffprobe.exe inside a bin folder and either add that bin folder to your PATH or point Flixlar to it.
Official downloads:ffmpeg.org/download.html
Linux (example)
Use your distribution package manager. For Debian/Ubuntu:
sudo apt install ffmpegOn some distros, packaged FFmpeg may be out of date — consider a distro-specific guide if you need newer builds.
Custom runtime path
Flixlar expects a runtime layout like this:
ffmpeg-runtime/
bin/
ffmpeg
ffprobe
Windows:
ffmpeg-runtime/
bin/
ffmpeg.exe
ffprobe.exe
Steps to configure
- Open Flixlar
- Open Dependencies
- Enter or browse to the runtime bin folder
- Click Test paths
- When both FFmpeg and FFprobe pass, click Use these paths
Troubleshooting
- Point to the bin folder — not the parent runtime folder.
- Verify both ffmpeg and ffprobe exist and are executable.
- Restart Flixlar after changing the runtime setup.
- On macOS/Linux, ensure binaries have executable permissions:
chmod +x ffmpeg ffprobe. - If automatic Homebrew detection fails, use the custom runtime path.
- If you don't want a local runtime, remove the local runtime and use a global installation instead.
Ready to go
Once FFmpeg and FFprobe are available, Flixlar will be able to export MP4s, burn subtitles into video, and detect detailed metadata.
