Pour ceux qui veulent un logiciel de montage vidéo ultra performant, et gratuit, vous avez Lightworks.
The Lightworks Open Source Project starts here...
Back in April 2010, we announced our plans to take Lightworks open source. We always said the first step would be to make the application freely available so that a large community of users could start becoming familiar with it. We are very pleased to have reached this first milestone. Now you can freely download the most intuitive and advanced editor available. This is not a trial download. From here forward, you will always be able to download and use the latest version of Lightworks for free.
Some time in the middle of 2011, we hope to reach our next milestone -- releasing the source code to any developer who wants to build upon what we started. We wish we were ready to do that now. However, before we can release any source, we have several hundred thousand lines of code to review to make sure it's all cleared for opening up. We are making progress but we are not there yet.
In the meantime, we invite you to get familiar with Lightworks, an Academy and Emmy award winning professional-grade editor with over 20 years of history in the film and broadcast industry. Having cut hundreds of films such as Pulp Fiction, The Departed, Centurion and Shutter Island, it includes a full feature set of editorial tools -- from advanced trimming and media management, to stereoscopic support and realtime effects including multiple secondary colour correctors. Lightworks has an advanced effects pipeline, utilizing the power of your GPU. And with support for up to 2K workflows with realtime effects, it is the most advanced editing application available.
