Blender is the free open source 3D content creation suite, available for all major operating systems under the GNU General Public License.
- It is a 3D editor and video editor. Complicated to use I hear, but works as good as Kdenlive for example.
- it cover all production pipeline include editing !
- If you are really demanding, Blender does not offer enough features and possibilities as an alternative to Flowblade which is a simple to use video editor on the one hand - but offers many different necessary features on the other.
