American Cinema Editors
Founded in 1950, American Cinema Editors (ACE) is an honorary society of film editors that are voted in based on the qualities of professional achievements, their education of others, and their dedication to editing itself. The society is not to be confused with an industry union, such as the I.A.T.S.E. (specifically the Motion Picture Editors Guild or MPEG) to which an editor might belong. The current President of ACE is Randy Roberts.
Eligibility for active membership can be obtained by the following prerequisites:
- Desire to be a member
- Sponsorship by at least two active members
- Minimum of 60 months (5 years) of editing experience on Features or Television
- Interview by the Membership Committee
- Approval by the Board of Directors
- Acceptance by the general membership
Members use the postnominal "A.C.E." as part of their signatures; thus the president of the Society in October 2012 was Randy Roberts, A.C.E. The society publishes its current membership on its website; as of 2012, this website does not include deceased members.

Eddie Awards 
Beginning in 1950, the ACE held an annual dinner to honor the film editing Academy Award nominees. When the National Academy of Television Arts and Sciences (NATAS) created a film editing category, the ACE invited them to the dinner as well.
In 1962, the ACE began giving its own awards. The following awards are either currently given or have been given in the past. An * denotes a film that also won the Academy Award for Editing.

Since 1951, the ACE publishes the CINEMAEDITOR quarterly magazine. It began as an in-house publication, but grew to 5,000 subscribers in 1963. In the early 1990s the magazine collapsed into a four page newsletter. In 1994, Jack Tucker was appointed as the Editor and he with President Tom Rolf and Laura Young expanded the publication into today's magazine. Walter Fernandez, Jr. leads the magazine's team, with publications committee chair Edgar Burcksen.
ACE Student Editing Competition 
The American Cinema Editors also holds an annual student competition (The ACE Student Editing Competition), awarding one student editor for editing a set of video dailies for a dramatic scene. Three finalists are guests at the annual ACE Eddie Awards in February. Applications are accepted through October and cost US$125. The competition is limited to the first 100 students only.
The Gunsmoke footage 
The ACE Store is the source of the dailies used at most film schools today. The scene is from a 1958 episode of the TV series Gunsmoke. It is available only to instructors of film editing classes. The video tape is called "FILM EDITING: Interpretation and Value" and includes three different edits of the scene.
