Jahshaka – Open source real time video editing and effects software

Some of the most expensive software packages are the ones which are related to the music and movie industry. Industry standard animation software and post production software for audio and video editing does not come cheap, for whatever reason. So if you are looking for a post production video editing software with professional capabilities but don’t want to empty your wallet, try this open source software Jahshaka.

Jahshaka is a cross-platform real time video editing and effects software which is geared towards beginners and intermediate users. While it might not be as powerful as the commercial tools developed by bigwigs like Adobe, Autodesk, Pinnacle and Sony, it has plenty of features and capabilities just waiting to be exploited.

  1. And as many other open source softwares, this one also is not user friendly. I tried a few months back. A video editing professional also failed to effectively use it. When will these open source freewares will be accessible to a layman?

  2. I found the interface confusing too but I thought it was just me, because I also find the interface of Blender confusing.
