Walter Murch's Rule of Six: Cut for Emotion

Q: In Murch's Rule of Six, which criterion carries the highest weight?

Emotion (being true to the feeling of the moment)。Emotion is 51%, more than the other five combined; spatial continuity is only 4%.

Q: True or false: 'Per Murch, as long as the space is cut perfectly continuous with no break, it counts as good editing even if the emotion is wrong.'

False。Quite the opposite — spatial continuity is only 4% and emotion is 51%; if the emotion is wrong, no amount of spatial continuity saves the cut.

An ideal cut should satisfy six things (but the weights differ wildly)

Master editor Walter Murch, in In the Blink of an Eye, breaks the abstract idea of 'a good cut' into six rankable criteria, each with a weight: ① Emotion (51%) — is it true to the feeling of the moment; ② Story (23%) — does it advance the narrative; ③ Rhythm (10%) — is the cut right, is it interesting; ④ Eye-trace (7%) — does it respect where the audience's attention is; ⑤ Two-dimensional plane (5%) — does it respect the compositional 'grammar'; ⑥ Three-dimensional continuity (4%) — does it respect real spatial continuity.

💡Note: emotion alone (51%) outweighs the other five combined. This turns 'good editing' from mysticism into a rankable, tradeoff-able engineering judgment. (These percentages are Murch's experiential estimates, not an exact formula.)

When you have to sacrifice, sacrifice from the bottom up

Murch gives an iron rule for tradeoffs: a cut can almost never satisfy all six, so always give up from the bottom up — first sacrifice 3D spatial continuity, then the 2D plane, eye-trace, rhythm, story — but never sacrifice emotion before anything else. Because satisfying the higher levels can mask flaws in the lower ones, but not the reverse: with an emotionally right cut, the audience won't even notice a spatial mismatch.

🔆His famous line nails why: 'What the audience ultimately remembers is not the editing, not the cinematography, not the performances, not even the story — it's how they felt.' That's 'cutting for emotion.'

💡The book's title, In the Blink of an Eye, hides another of Murch's metaphorical observations: people blink when one thought ends and the next begins — a blink is the punctuation of thought. A good cut often lands at the moment the audience has 'seen enough and is ready for a new image.' By Murch's own account, while cutting The Conversation he often cut exactly where the actor blinked.

In Murch's Rule of Six, which criterion carries the highest weight?

答案：Emotion (being true to the feeling of the moment)

Emotion is 51%, more than the other five combined; spatial continuity is only 4%.

When a cut can't satisfy all six at once, how should you trade off, per Murch?

答案：Give up from the bottom (3D spatial continuity) upward, and never sacrifice emotion first

Higher levels can mask flaws in lower ones, so sacrifice from the bottom up; emotion is always the last to go.

True or false: 'Per Murch, as long as the space is cut perfectly continuous with no break, it counts as good editing even if the emotion is wrong.'

答案：False

Quite the opposite — spatial continuity is only 4% and emotion is 51%; if the emotion is wrong, no amount of spatial continuity saves the cut.
