What’s great about most Linux video editing software applications is that they tend to be free and open source, which means that anyone can peek under the hood and implement new features or fix bugs. The video editors featured in this article are loosely arranged according to their popularity, but we recommend you go through the entire list because even less popular video editors have a lot to offer.

Cinelarra is for video producers who need more than OpenShot, and who want a native Linux professional-quality video editor that supports high-resolution audio and video, and advanced features such as hue and saturation, overlays, denoising, compression, normalization, time stretching, realtime effects, nested sequences, color balance, image flipping, text-to-movie, batch render and batch capture, compositing, and much more. Cinelarra has nice integration between audio and video, and makes it easy to control synchronization. Blender and Cinelarra work well together; create your splendid animations in Blender and then integrate them into a movie in Cinelarra.
