Lightworks is a rising video editing software that keeps getting better and better in the latest years. A completely free software, that gives everything you need to create your own videos and slideshows, by allowing Text, Transitions, Video and Audio Effects, but also advanced editing, such as envelope lines and Keyframes.
Since the latest version, the user interface has been improved deeply, bringing this software a very great and cheap alternative to other products on payment.
The Free version does not have any heavy limitations, except for the render options, which are available only for online websites (YouTube and Vimeo), and up to 720p HD only.
A PRO version is available under subscription basis. As Movie Studio and Vegas Pro, this software is perfect for manual editing, but does not provide any automation or ready-project templates.
