Where the eye goes first
If a cut lands while somebody is still reading, the speed has cost you what you were buying.
Somebody told you the edit was too slow, so the next one came back quicker. More cuts, more movement, a zoom on every line, text flying in from the side.
It feels urgent now. It also performs about the same, or slightly worse, and nobody can say why.
Here is why. Speed does not hold attention. Speed only removes the parts where nothing was happening. What holds attention is a viewer who is following something, and a viewer stops following the moment the picture changes while they are still working out the last one.
Why does a fast cut lose people?
Because reading and watching use the same attention, and cutting interrupts both.
A line of text takes a real amount of time to read: the eye has to find it, cross it, and finish it. That is not a preference, it is how reading works. If the shot changes before the line is done, the sentence is gone. The viewer does not think I missed that, they simply feel behind, and feeling behind in a feed has one outcome.
The same applies without text. A new location, a new face, a hand entering frame: each needs a moment to be understood before it can mean anything. Cut before that moment and you have paid for a shot nobody saw.
An ad that moves quickly and is understood is fast. An ad that moves quickly and is not understood is noisy, and the two look identical in an editing timeline.
Where is the viewer actually looking?
Somewhere specific, and rarely everywhere.
At any moment there is one place the eye has gone: a face, usually the eyes on that face, the brightest part of the frame, the thing that just moved, or the words. It is a queue rather than a crowd, and when two things compete for it one of them loses. You do not get to pick which.
This is what an eye path means. Work out, shot by shot, where the eye is most likely to go, build the cut around that, then check it rather than trust it, so the next important thing arrives where the eye already is rather than in the corner it has just left.
The consequence is unglamorous. If the eye ends a shot on the left, put the next thing on the left. If a face is talking, do not put your key sentence in the opposite corner and expect both to land.
How long does a line of text need on screen?
Read it aloud, at a normal speaking pace, and time that. That is the minimum, and slightly more is safer.
A viewer in a feed is reading in worse conditions than you are: smaller screen, moving hand, half attention, somebody probably talking to them. And if you are checking the timing by reading the line in your head while already knowing what it says, you are not checking anything.
Do it for every line, out loud, at the speed you would say it to a stranger. If the line disappears before you finish, it is too short, and the fix is either more time or fewer words. Fewer words is usually the better fix and the one nobody wants.
What should never share a frame with movement?
The thing you need read. In practice that means the offer, the price, the promise and the button text.
If your key sentence appears while the camera is pushing in, while a transition is resolving, or while a hand crosses the frame, it is competing against motion, and motion wins. That is not a stylistic claim. Movement is what human vision notices first, and no typography beats it.
So the important sentence gets a still moment. Let the movement finish, then show the words, or show them over something calm. It costs a fraction of a second and it is the difference between an offer that was displayed and an offer that was read.
The same goes for stacking. Do not introduce a new element while the previous one is still being read. Two captions overlapping, a logo animating in under a headline, an offer appearing while a product name is still on screen: each splits the queue and neither item gets through.
Three checks before it goes live
None of these need software and all of them work on the version you already have.
Read every on-screen line aloud, at normal pace, and mark the ones that vanish before you finish. Watch the ad muted and note the moment you first feel behind, because that is where the drop is. Then watch it once looking only at the top left corner, which is a crude way of finding out how much of your ad is legible only to somebody paying full attention.
Fix in that order. Timing first, since it is free. Then reordering. Then recutting, and only if it is still not working.
Building the cut around the eye rather than the beat
Most edits are built to the music, because music gives you a grid and a grid is comfortable. The beat does not know where the viewer is looking, and an ad cut purely to a beat will occasionally land a change of shot precisely in the middle of somebody's sentence.
In this studio the eye path is worked out first and the cut is built around it, which means the music is fitted to the edit rather than the edit to the music. It is a slower way to start and it removes an entire category of fault: a change that arrives where nobody is looking, or arrives while somebody is still reading.
What that leaves you with is a question about your current ad rather than your next one. Watch it once more and find the first cut that lands on a sentence. There is usually one, it is usually early, and moving it is a decision you can make today.
