While he was editing directly on film, Murch took notice of the crude splicing used for the daily rough-cuts. In response, he invented a modification which concealed the splice by using extremely narrow but strongly adhesive strips of special polyester-silicone tape. He called his invention "N-Vis-O". In 1979, he won an Oscar for the sound mix of
Apocalypse Now as well as a nomination for picture editing. The movie was among the first stereo films to be mixed using an automated console. Additionally, the film is the first to credit anyone as
Sound Designer, a professional designation that Murch is widely attributed to have coined as a means to help legitimize the field of post-production sound, much in the way
William Cameron Menzies coined the term "Production Designer" in the 1930s.
Apocalypse Now was also notable for being the second film released in a Dolby sound system that has come to be known as 5.1, with three screen speaker channels, low-frequency enhancement, and two surround channels (one more channel than standard surround sound arrangements at the time). The movie was initially seen and heard in this 70mm six-track format in only 17 theaters, some of which also featured prototypes of the Model 650 subwoofer developed by John and Helen Meyer. In recent years, Murch has asserted that the Meyer Sound subwoofers were more "emotionally significant" to the film's presentations than were the two surround channels. In 1996, Murch worked on
Anthony Minghella's
The English Patient, which was based on
Michael Ondaatje's novel of the same name. Murch won Oscars both for his
sound mixing and for his
editing. Murch's editing Oscar was the first to be awarded for an electronically edited film (using the
Avid system), and he is the only person ever to win Oscars for both sound mixing and film editing. In 2003, Murch edited another
Anthony Minghella film,
Cold Mountain on
Apple's sub-$1000
Final Cut Pro software using off the shelf
Power Mac G4 computers. This was a leap for such a big-budget film, where expensive
Avid systems were usually the standard
non-linear editing system. He received an Academy Award nomination for this work; his efforts on the film were documented in Charles Koppelman's 2004 book
Behind the Seen. In 2006, he was awarded an honorary doctorate of letters by the
Emily Carr Institute of Art and Design in Vancouver, Canada. In 2009, Murch's work was the subject of a tribute, "The Art of Walter Murch," a program in "The Professionals," a series by the California Film Institute at the Christopher B. Smith Rafael Film Center. Murch is the 2012 recipient of the Nikola Tesla Award given by the
International Press Academy Satellite Awards for "Visionary Achievement in Filmmaking Technology". Previous recipients have included
Douglas Trumbull,
James Cameron,
Roger Deakins,
Dennis Muren and George Lucas. In 2015, Murch was presented with the Vision Award Nescens, at the 68th Locarno Film Festival, for his contributions to cinema. The two previous recipients of the award, initiated in 2013, were Douglas Trumbull and Garrett Brown. In 2016, he was awarded an honorary doctorate of media by the Southampton Solent University in Southampton, England along with
Anne Coates who received an honorary Doctorate of Arts. Murch has a long term association with the
University of Hertfordshire; initially contributing an oral history interview with
The Elstree Project in 2013. There is a dedicated post-production lab on the Hertfordshire campus named for Murch which opened in 2015. In 2018, Murch was awarded an honorary doctorate of arts by the University, for his contribution to the film industry in the county of Hertfordshire, his contribution towards The Elstree Project, and the Film and Television Production degrees. Murch and Hertfordshire's Head of Post-Production lecturer Howard Berry teamed up to create the documentary
Her Name Was Moviola, which received its premiere in 2024. Students from Berry's film degree worked on the film as crew. In 2024 he was awarded the ACE Career Achievement Award at the
74th American Cinema Editors Eddie Awards in March. In May of that same year, he was awarded an honorary doctorate by Ravensbourne University London for his outstanding contribution to cinema and his seminal writings on the craft of film editing. In August 2025, Murch was awarded an Honorary Degree by the
AFI. Murch is also Honorary Associate of
London Film School. He is the only film editor to have received Academy Award nominations for films edited on four different systems: •
Julia (1977) using upright
Moviola •
Apocalypse Now (1979),
Ghost (1990), and
The Godfather Part III (1990) using
KEM flatbed •
The English Patient (1996) using
Avid •
Cold Mountain (2003) using
