5. Avid Media Composer
Avid Media Composer is the grand emperor of non-linear video editing programs. Not only was Avid the first to release a non-linear system, it has remained the film industry standard and the most complete out of all professional video editing programs.
For those who are intending to work in industry led post-production, Avid Media Composer is going to be a must as it is still used in most of the feature industry, though Final Cut Pro is challenging its superiority at all levels. Though most lower level video editors may not have used Avid, it still stands out as being the most complete system out there. Avid is known for having a huge list of tools and a package of third party programs that come with it to create a complete system, and there is even a set of Avid specific hardware that you can use along with it in a way that is similar to Pro Tools. This is partially why many computers are Avid specific and there are Avid systems used in post-production houses, often times with Avid software used for server and media sharing.
Avid Media Composer is not, however, practical for many users as the price ranges from about $2,300 to $2,500. Avid is actively trying to gain back many of the Final Cut Pro users, especially those that have started to learn video editing through Final Cut Pro, so you can see that it is only going to increase the fight between the two leaders in professional film editing.
