The Journey to Modern Non-Linear Editing (Part 1)
Main summary
Key takeaways
Main ideas / concepts conveyed
- Editing is as old as filmmaking: From early filmmakers onward, the goal has been to remove unwanted/boring segments and keep the best material.
- Mechanical and analog editing set the stage
- Physical film splicing is described as intuitive with traditional celluloid workflows.
- Early editing machines like Moviola (since the 1930s) and Steenbeck flatbeds (popular in the 1970s, still used in specialty contexts) represent this era.
- The push toward computer-style editing was driven by TV’s need to record and distribute content
- Early television broadcasting had to be live, since electronic recording wasn’t yet possible.
- To record for delayed viewing, networks used kinescopes (filming a monitor).
- Videotape enabled recording and eventually editing—but early videotape editing was cumbersome
- Videotape adoption grows after major engineering breakthroughs (e.g., Ampex systems).
- Editing tape required specialized, destructive, and highly technical physical processes.
- A major split emerges: linear vs. non-linear editing
- Linear editing assembled video in order; changes near the start forced redoing later work.
- Non-linear editing (NLE) is presented as nondestructive, allowing reordering and revisions without destabilizing the rest of the edit.
- Non-linear editing becomes practical with digital storage + computing power
- Early “NLE” systems appear as expensive prototypes/experiments, then mature with systems like Avid.
- “Offline” workflows emerge with Avid-era NLE
- Editors create lower-quality “work cuts,” then generate decisions (via EDL/timecode) for conforming/making final high-quality originals.
Timeline / evolution of editing (as described)
1) Live TV broadcasting and kinescopes (early era)
- 1936 (BBC) begins public regular television broadcasts (first regular service mentioned).
- WWII interruption delays widespread adoption.
- 1948 (US): first commercial US television broadcasts begin; TV explodes during the 1950s.
- Problem: everything is live; there’s no way to electronically record for time-zone delays.
- Solution: kinescope
- A film camera records a video monitor’s output.
- Challenges: poor image reproduction (e.g., “ghosting” and “banding”).
2) Network distribution logistics (example: “hot kinescope”)
When networks went coast-to-coast:
- Shows produced in the East were recorded on kinescope in the West.
- Film was rushed to development and broadcast quickly.
- Called “Hot Kinescope” because it was sent to air before cooling.
3) Videotape replaces kinescope (cost and capability drive the change)
- Networks used huge amounts of film stock for kinescopes (described as more than Hollywood studios combined by mid-1950s), motivating cheaper alternatives.
- Magnetic audio tape existed, but video-on-tape was harder.
- 1951: first recorded video images onto magnetic tape (attributed to engineers connected to Bing Crosby’s production company).
- Result: image was poor, but it proved feasibility.
- 1956: Ampex releases first commercially available video tape recorder (2-inch quadruplex).
- Huge sales surge after a NAB demonstration.
- 1956–1957:
- CBS first uses it for west-coast delay broadcast (given example date).
- NBC example: first program broadcast across all time zones using pre-recorded video tape.
4) Videotape as both technology and geopolitics (Cold War “Kitchen Debate”)
- 1959 Moscow exhibit: an American tech display includes a model TV studio with an Ampex recorder.
- Nixon and Khrushchev visit; leads to a political debate.
- Tape is rushed back, then aired back home (as described).
- The narrative emphasizes videotape’s role in global communications/events.
Editing methods described (detailed bullet points)
A) Early videotape editing (2-inch quadruplex) — described as extremely difficult
- Editing is possible but “more cumbersome than film.”
- Step-by-step (as explained):
- Develop the tape so the magnetic tracks become visible:
- Uses very fine iron filings suspended in toxic carbon tetrachloride to reveal magnetic bands.
- Alignment is done by viewing through a microscope.
- Splicer alignment + precise cutting:
- Cut must occur exactly during a vertical retrace signal.
- Must preserve field ordering (odd/even-field ordering).
- Separate video vs audio head positioning complicates physical edits
- Video and audio heads are physically separated by several inches.
- Therefore, you can’t make one physical cut that keeps both video and audio in correct alignment.
- Workflow becomes:
- Make the cut for video
- Cut/copy/re-record an appropriate portion of audio
- Reestablish correct audio/video relationship afterward.
- No reliable “still frame” viewing
- Quadruplex tape is described as not being capable of holding stable still frames during editing.
- Develop the tape so the magnetic tracks become visible:
- Net effect: editing requires destructive/physically constrained labor and careful reconstruction.
B) NBC “ESG” style workaround — offline editing concept emerges (kinescope work prints)
- Purpose: make editing manageable even before tape editing becomes practical/accurate.
- Core idea:
- Edit using kinescope film work prints.
- Film prints include audio cues.
- Editors later match these cues back to tape/video splices.
- Named concept:
- ESG described as a process “similar to what would later be called offline editing.”
- Offline editing meaning (as stated):
- Edit using lower-quality copies of the original material.
- Later assemble the high-quality originals based on the edit decisions.
C) Linear editing — assembling in sequence (more “technical profession” than creative freedom)
- Mechanism described:
- Use two video decks to transfer and build a show linearly.
- Assemble by making cuts one after another in order.
- Challenges described:
- Need to ensure signals between decks match correctly (synchronization).
- Technological enablers mentioned:
- 1963 Ampex “Editec”: electronic recorder with microprocessor to control in/out points (audible tones).
- Helical scan systems
- Wrap tape around spinning head to increase bandwidth; makes pausing/individual frame access easier.
- 1967 SMPTE timecode
- Frames get addresses (hours/minutes/seconds/frames),
- Enables locating any frame precisely.
- Result:
- Linear editing becomes common in the 1970s.
- Editing becomes heavily focused on technical documentation:
- EDLs (Edit Decision Lists) replace “creative flexibility.”
- Rough cut limitation
- Because assembly is linear, changing early parts forces redoing later segments.
- The narrative concludes: “there was no such thing as a rough cut” in this model.
D) Non-linear editing — the creative break (nondestructive, reorder freely)
- Core properties emphasized:
- Nondestructive editing: changes don’t break or disturb the rest of the timeline.
- Arbitrary reordering: you can assemble a cut in any order.
- No generation loss
- Linear editing may require copying from tape to tape, risking quality loss.
- NLE avoids that by design (as described).
Evolution of NLE systems (early to mainstream)
- 1971: CMX 600 described as the first NLE
- Very expensive; outputs described as half-resolution black-and-white files stored on large disk packs.
- Only a few produced.
- 1980s: development depends on computing power + storage
- Mentioned experiments:
- EditDroid (1984) (George Lucas spin-off / DroidWorks):
- Uses LaserDisks; not successful; shut down in 1987.
- Multiple VCR banks tried, but described as too slow/cumbersome.
- EditDroid (1984) (George Lucas spin-off / DroidWorks):
- Mentioned experiments:
- 1988: EMC2 introduces first all-digital offline NLE using optical disks.
- 1989: Avid1 public release (Macintosh-based NLE)
- Later becomes “gold standard” for Hollywood editing (as claimed).
- 1993: larger Avid storage upgrade
- Adds a 7 terabyte system for feature-length capability.
Offline → conform workflow (Avid-era)
- Editors create low-quality offline work cuts.
- Use timecode/EDL to deliver decisions to a film lab for final assembly.
Noted milestones
- First studio film cut on Avid: Lost in Yonkers (1993).
- Editor Walter Murch wins Oscar for Best Editing for The English Patient (1996), described as cut offline on an Avid.
Method demonstration included (Avid “assemble edit” concept)
- The video includes an on-screen example of NLE editing:
- A bin organized as a list of assets (images/frames).
- Steps:
- Perform an assemble edit
- Drag the first element into the record window
- This creates the first edit and places it on the timeline
- Drag additional elements to build a sequence quickly
Overall lesson / conclusion of Part 1
- The journey from analog mechanical editing to modern non-linear editing is driven by:
- TV’s need to record and distribute (kinescopes → videotape)
- Advances in how editing can be performed (from destructive/cumbersome tape edits to offline/linear systems)
- Non-linear editing’s creative advantages (nondestructive, reorder freely, avoid generation loss)
- Digital storage and computing improvements, culminating in systems like Avid
- Part 1 ends by noting Part 2 will cover the digital and computer-science revolution.
