Editing and Cut Grammar

1. Editing first principles

Editing controls audience inference across time.

EDIT
= select
+ bound
+ order
+ duration
+ juxtapose
+ overlap
+ omit
+ repeat
+ transform
+ mix

A cut creates a relationship between two time ranges.

CUT(A, B)
= exit state of A
+ entry state of B
+ change dimensions
+ continuity dimensions
+ transition timing
+ intended inference
+ risk of unintended inference

2. Cut-decision vector

CutVector = {
  from_shot,
  to_shot,
  cut_frame,
  audio_cut_frame,
  motivation,
  semantic_relation,
  narrative_relation,
  temporal_relation,
  spatial_relation,
  visual_match,
  motion_match,
  gaze_match,
  sound_bridge,
  information_gain,
  emotional_change,
  continuity_requirements,
  discontinuity_intent,
  transition_type,
  transition_duration,
  reversibility,
  provenance
}

3. Fundamental cut motivations

A cut should do at least one of the following:

CHANGE_INFORMATION
CHANGE_INFORMATION_OWNER
SHOW_CAUSE
SHOW_EFFECT
SHOW_REACTION
ORIENT_SPACE
COMPRESS_TIME
EXPAND_TIME
CHANGE_EMOTIONAL_DISTANCE
COMPARE
CONTRAST
REVEAL
CONCEAL
CORRECT_CONTINUITY
HIDE_REMOVAL
CREATE_RHYTHM
FULFILL_EXPECTATION
BREAK_EXPECTATION
TRANSITION_TOPIC/PLACE/TIME

BODY_PASS_CUT
DOORWAY_CUT
SCREEN_OR_DEVICE_CUT

Montage cuts

METRIC — duration-based
RHYTHMIC — movement/content rhythm
TONAL — emotional tone
OVERTONAL — combined metric/rhythmic/tonal effect

PROCESS_MONTAGE
ACCUMULATION_MONTAGE
ASSOCIATIVE_MONTAGE
PARALLEL_MONTAGE
COLLISION_MONTAGE

5. Transition taxonomy

A transition modifies the relationship across the boundary.

CUT
DISSOLVE
CROSSFADE
FADE_TO/FROM_BLACK
FADE_TO/FROM_WHITE
DIP_TO_COLOR
WIPE
IRIS
PUSH
SLIDE
ZOOM_TRANSITION
BLUR_TRANSITION
DEFOCUS_TRANSITION
MORPH
MATCH_MORPH
GLITCH
FILM_BURN
LIGHT_LEAK
PAGE_TURN
SPEED_RAMP_TRANSITION
CUSTOM_MATTE

Rules:

IF time passes gradually or two states coexist
THEN a dissolve may encode that relationship.

IF a chapter ends decisively
THEN cut, fade, or dip according to desired closure strength.

IF a transition effect has no semantic, spatial, temporal, or stylistic function
THEN prefer a cut.

IF the transition attracts more attention than the story change
THEN reduce or remove it unless spectacle is the function.

6. Trim-operation grammar

SELECT_RANGE
BLADE
TRIM_IN
TRIM_OUT
RIPPLE_TRIM
ROLL_EDIT
SLIP_EDIT
SLIDE_EDIT
INSERT_EDIT
OVERWRITE_EDIT
REPLACE_EDIT
LIFT
EXTRACT
THREE_POINT_EDIT
FOUR_POINT_EDIT
FIT_TO_FILL
EXTEND_EDIT
MATCH_FRAME
TOP_AND_TAIL

Semantic meaning:

RIPPLE changes one boundary and downstream timing.
ROLL changes the boundary between adjacent clips without changing total sequence duration.
SLIP changes content inside fixed timeline boundaries.
SLIDE moves a clip while adjusting its neighbors.
INSERT creates time; OVERWRITE replaces time.
LIFT leaves time; EXTRACT removes time.

7. Cut timing dimensions

word boundary
phoneme boundary
breath
pause
blink
gaze shift
gesture anticipation
action onset
action apex
action completion
music beat
music phrase
sound transient
emotional turn
information completion
reaction latency
frame cadence

Cut frame selection should consider all active timing signals, then prioritize the story function.

8. Dialogue-cut grammar

Clean removal

premise → repetition → conclusion
becomes
premise → conclusion

Only when the removed material does not contain qualification, emotion, causality, or evidence.

Question-answer preservation

QUESTION establishes scope, subject, polarity, and context.
ANSWER inherits those fields.

If the question is removed, the answer must be rewritten by narration, graphic, or intact wording so its referents and truth conditions remain clear.

Filler and disfluency rules

IF disfluency has no semantic, emotional, relational, or credibility value
THEN it may be removed.

IF hesitation reveals uncertainty, fear, care, deception risk, or cognitive effort
THEN preserve or review manually.

IF removing a filler creates an impossible mouth or body discontinuity
THEN use alternate angle, B-roll, graphic, audio-only repair, or retain it.

9. Jump-cut grammar

Jump cuts can encode:

compression
urgency
fragmentation
self-awareness
comedy
repetition
memory
platform-native directness

Jump-cut rules:

IF the visual discontinuity is not intended
THEN cover, reframe beyond a configured scale threshold, or use a motivated transition.

IF a series of jump cuts is intentional
THEN maintain a rhythm or escalation pattern.

IF a jump cut occurs during sensitive testimony
THEN verify it does not imply manipulation or emotional discontinuity.

10. Match-cut grammar

A match requires one preserved dimension and one changed dimension.

MATCH_CUT
= invariant(feature)
+ transformation(context)

Possible invariants:

shape
position
movement vector
movement phase
color
texture
sound
word
idea
gaze
gesture
scale
light direction

Possible transformations:

time
place
subject
meaning
status
medium
scale
cause/effect

11. Reaction-cut grammar

A reaction shot is evidence of reception.

Store:

stimulus_time
reaction_onset
reaction_peak
reaction_decay
reactor identity
relation to speaker
interpretive risk

Rules:

Never relocate a reaction so it appears to answer a different stimulus without disclosure.
Use reaction when it changes meaning, emotion, relationship, or pace.
Do not cut away from the speaker at the key moment when facial performance carries the primary truth.

12. B-roll and cutaway grammar

B-roll functions:

EVIDENCE
MECHANISM
ORIENTATION
TEXTURE
CHARACTER
CONTRAST
METAPHOR
TIME_COMPRESSION
EDIT_COVER
FORESHADOW
CALLBACK
TRANSITION

B-roll rules:

IF B-roll depicts the exact claim
THEN verify factual and temporal fit.

IF B-roll is illustrative rather than evidentiary
THEN avoid editing that makes it appear to be direct proof.

IF generic stock imagery reduces specificity or introduces stereotypes
THEN prefer document, diagram, location detail, process, or restrained speaker coverage.

IF B-roll covers a dialogue edit
THEN ensure its in/out duration and motion permit clean return to sync.

13. Montage grammar

A montage contains a governing transformation:

MONTAGE
= item set
+ ordering principle
+ duration rule
+ repetition/variation
+ escalation or accumulation
+ sound structure
+ exit condition

Ordering principles:

chronology
magnitude
similarity
contrast
geography
process stage
cause/effect
emotional intensity
visual shape
sound rhythm
argument strength

14. Rhythm grammar

Track intervals rather than relying only on intuition:

shot_length_series
cut_density
cut_acceleration
speech_phrase_length
pause_distribution
motion_onsets
sound_transients
music meter and phrase
visual complexity

Rhythmic rules:

IF cut rate accelerates
THEN ensure information density and audience comprehension remain within target.

IF every cut lands exactly on a music beat
THEN vary phrase position unless mechanical synchronization is the intended style.

IF a climax needs impact
THEN consider contrast in rate, silence, scale, or duration rather than acceleration alone.

15. Invisible-edit grammar

An edit tends to feel continuous when it preserves enough of:

attention target
action phase
eyeline
screen direction
body position
lighting
sound continuity
motion direction
visual center
causal expectation

The system can score visual continuity but should not assume invisibility is always the goal.

16. Discontinuity grammar

Deliberate discontinuity can operate on:

time
space
identity
scale
angle
color
sound
movement
style
medium
causality

Declare:

discontinuity purpose
duration
audience state intended
reorientation method

17. Edit-decision rules

IF a new speaker begins AND their identity/location is unclear
THEN show or establish them.

IF a claim names a visible document, object, process, or number
THEN consider an evidence insert or graphic at the moment of reference.

IF a cut would interrupt the emotional apex of a performance
THEN hold unless reaction, evidence, or concealment is more important.

IF the audience already understands space
THEN omit redundant establishing coverage unless pacing requires reset.

IF two adjacent clips repeat the same proposition
THEN keep the stronger performance or combine complementary evidence.

IF the next scene’s sound creates useful anticipation
THEN use a J-cut/prelap.

IF the prior emotion should linger into a new image
THEN use an L-cut/postlap.

IF chronology is compressed
THEN retain enough temporal markers to prevent false simultaneity or causality.

18. Edit candidate scoring

EditScore
= meaning_integrity
+ narrative_function
+ causal_clarity
+ emotional_continuity
+ visual_continuity_or_intended_contrast
+ audio_continuity
+ rhythm
+ information_gain
+ format_fitness
- confusion
- false_inference_risk
- technical_artifact
- repair_cost

19. LAKA cut variations

Baseline

same order; clean trims; preserve coverage and rhythm

Minor

alternate cut frame
J-cut vs straight cut
one reaction or insert
small duration change

Major

new coverage pattern
jump-cut treatment
montage replaces continuous scene
new sound-bridge strategy

Structural

intercut timelines
reorder chapters
parallel montage
nonlinear reveal

Paradigm

continuous observational scene becomes essay montage
visual story becomes audio-led experience
linear edit becomes interactive branching sequence

FALSE_CAUSAL_ADJACENCY
QUESTION_ANSWER_DISTORTION
REACTION_RELOCATION
OVER_CUTTING
UNDER_CUTTING
MUSIC_VIDEO_SYNDROME
BROLL_AS_FALSE_EVIDENCE

21. Cut acceptance test

Why this frame?
What relationship does the cut create?
What remains continuous, and what changes?
Does the audience infer anything untrue?
Does audio lead, follow, or align for a reason?
Does the transition fit time, space, emotion, and style?
Is the cut repairable and reversible?
Does it preserve accessibility and all delivery versions?
