# About Kdenlive
[Kdenlive](https://kdenlive.org) is a Free and Open Source video editing application, based on MLT Framework and KDE Frameworks 6. It is distributed under the [GNU General Public License Version 3](https://www.gnu.org/licenses/gpl-3.0.en.html) or any later version that is accepted by the KDE project.
# Building from source
[Instructions to build Kdenlive](dev-docs/build.md) are available in the dev-docs folder.
# Testing Kdenlive via Nightly Builds
- AppImage (Linux): https://cdn.kde.org/ci-builds/multimedia/kdenlive/master/linux/
- Flatpak (Linux):
- Add the kde flatpak repository (if not already done) by typing `flatpak remote-add --if-not-exists kdeapps --from https://distribute.kde.org/kdeapps.flatpakrepo` on a command line. (This step may be optional in your version of Flatpak.)
- Install kdenlive nightly with `flatpak install kdeapps org.kde.kdenlive`.
- Use `flatpak update` to update if the nightly is already installed.
- _Attention! If you use the stable kdenlive flatpak already, the `*.desktop` file (e.g. responsible for start menu entry) is maybe replaced by the nightly (and vice versa). You can still run the stable version with `flatpak run org.kde.kdenlive/x86_64/stable` and the nightly with `flatpak run org.kde.kdenlive/x86_64/master` (replace `x86_64` by `aarch64` or `arm` depending on your system)_
