Show Time Passing in a Commercial Without Losing the Thread

A time jump in a commercial treatment is usually written as a feeling: dissolve, light shift, same street in winter. Then the client reads the later scene and asks how the character got there. That question is about a missing cause, not a missing date.

Decide what the viewer carries across the cut

Before writing the transition, write the two states it connects. Not the images — the states. Who is pursuing what, what object or task persists from the first scene into the second, and what the later scene quietly assumes the viewer already knows.

Then ask a narrower question of the gap: does it contain only elapsed time, or does it contain an action the next moment depends on?

These are different problems and they take different cues. If a man finishes a cup of coffee in one scene and reaches for a second in the next, nothing causal has been skipped. Time passed. A cut, a fresh pour, a moved chair — any of these will read. If the same man answers a phone call in the later scene and tells someone he has quit smoking, the omitted interval contains a decision. No dissolve repairs that. The audience will watch him answer the phone and wonder what they missed, because they did miss something, and it wasn't duration.

So the treatment has to distinguish two kinds of omission:

Omitted duration. The viewer needs to know that time has passed, and nothing else. The later scene is fully motivated by what we already saw.

Omitted causal action. The later scene rests on something that happened off-screen. The film can hide it, but then it must plant it — show the cause and cut the redundancy — or the later moment will feel like a cheat.

The first is a transition problem. The second is a story problem. Most broken time jumps in treatments are the second one wearing the first one's clothes.

Give continuity and change separate jobs

A readable jump keeps one recoverable anchor while changing a condition that matters. Anchor: the thing the viewer can still identify — a place, a face, a gesture, an object, a routine. Changed condition: the thing the jump is actually about — the state of the pursuit, the wear on the object, the ease of the performance.

Write both, as an observable pair of moments. This is the whole craft of the thing, and it is more literal than it sounds.

Weak:

A beautiful passage of time as our hero grows and learns.

Strong:

SCENE 3 — REHEARSAL ROOM, LATE AFTERNOON. He plays the same eight bars. His left hand hesitates on the fourth beat. He stops, marks the bar with a pencil, starts again from the top.

SCENE 4 — SAME ROOM, MORNING LIGHT. Same eight bars. The hesitation is gone. He plays through to the end and looks at the pencil mark, still on the page, now crossed out.

The anchor is the room plus the pencil mark. The changed condition is the hesitation. The duration — overnight, a week, a year — is deliberately unspecified, because the proposition doesn't turn on it. What the viewer needs is a before and an after of the same action, so the difference reads as change rather than as a different person doing a different thing.

A pair like this proves the cut is legible. It does not account for why the change happened, and those are separate debts. The change here — a hesitation smoothed out — is the kind ordinary practice produces, and a viewer can infer the practice without being shown it, so the jump stands on its own. A film that ends by promising a solved problem performed for an audience asks for more: there the cause has to be visible rather than inferable, and the drill shown later is what supplies it.

The common failure is to change everything at once. New location, new costume, new lighting, new supporting cast, and then a title card explaining that we are now in the future. When nothing survives the cut, the viewer has no way to compare; they can only be told. A title card is doing the work the image should have done.

A second failure is to change nothing that matters. Two scenes in the same room with the same performance and a lamplight shift: the viewer sees time pass but cannot say what it cost or bought. Continuity without consequential change is just a cut with better lighting.

Protect the event that makes the later moment possible

Separate routine the film can omit from a decision that causes the next state. A character who suddenly knows, owns, or can do something may need a planted event — a decision, a first attempt, a repair — rather than a calendar insert.

This is where the causal jump earns its keep. Suppose the commercial is about the rehearsal above, and the later scene ends with the performer nailing the passage in front of an audience. Three things are true:

The practice is routine. It can be compressed, repeated, shown as a montage of the same bars at different hours. Omitting most of it is fine. The audience understands that practice takes practice.
The difficulty is the point. The hesitation on the fourth beat has to be shown at least once, or the later ease has nothing to contrast with.
The decision that redirected the practice is neither. If, between the first attempt and the breakthrough, the performer chooses to slow the passage down and drill the fourth beat alone — and the breakthrough depends on that choice — then cutting it leaves the audience watching a success they cannot account for. They will not ask how long it took. They will ask why it happened.

The repair is not a longer transition. It is a shorter film with a different sequence:

Rejected: bars → dissolve → bars played perfectly → applause.

Kept: bars → hesitation → pencil mark → slowed version of the same bar, alone, at half tempo → same slowed bar, at tempo → bars played perfectly → applause.

The slowed version is the planted event. It costs a few seconds and it converts the jump from a magic trick into a cause. Everything the audience needs is now visible, and the only thing omitted is the repetition — which is the part they can infer.

Note what is not here: a caption reading "three days later." The duration is real but it is not load-bearing. If the later scene depended on a specific interval — say, an injury that heals in a stated number of weeks, or a product that claims a stated speed of effect — then the duration becomes a claim, and it needs evidence, not a title card. The method in this article can make a jump legible. It cannot make a timing claim true.

Choose the cue for this interval

Once you know whether you are bridging duration or cause, the cue is a local decision. The categories below are options, not a dictionary — weather does not mean "a month," and a beard does not mean "years" without help from the rest of the film.

Performance. The same action executed with more or less ease, speed, or confidence. Good for skill, recovery, and habit. Needs the action to be shown before, so the change has a referent.
Wear or state of an object. A pencil mark, a worn patch, a full versus empty shelf. Good for routine and for making duration visible without naming it. Requires the object to be planted earlier and to stay in frame.
Environment. Light, season, the state of the room. Good for suggesting that time passed. Weak at specifying how much, and weak at carrying cause, which is why it is usually a supporting cue rather than a primary one.
Repeated action. The same establishing beat, once at the top and once later, doing double duty as anchor and clock.
Sound. A cue picked up before the cut and completed after it — a note, a phrase, an alarm — can bind two states together and imply the interval without claiming a length.
Explicit text. A date, a card, a visible calendar. Strongest as a duration cue, most easily overused, and least able to substitute for a missing cause.

The test for any cue is what it actually conveys, not what it evokes. A costume change can mean overnight or a decade. That is not a flaw if the film doesn't need the interval pinned down. It is a flaw if the proposition depends on "after the treatment" or "before the deadline" and the cue leaves the side of the boundary ambiguous.

For the rehearsal example, the cue is the pencil mark: it was made in Scene 3, it is still on the page in Scene 4, and it is now crossed out. The mark carries continuity; the crossing-out carries change; the unchanged room carries the anchor. Nothing states the interval, and nothing needs to, because the film's claim is about mastery, not about elapsed days.

Read the sequence without its notes

Now strip the treatment back to images and sound and trace what a viewer on the page could plausibly infer at each cut. Where does an essential fact become unavailable? Fix that. Where the uncertainty is deliberate — the film is happy for you to wonder how long he's been at this — leave it alone.

The rehearsal sequence, read cold:

He plays eight bars; the fourth beat stumbles; he marks the page. What the sequence on the page cues: the passage is hard, and he is trying to fix one spot.
Slowed version of the fourth beat, alone, then the same passage at tempo. What the sequence on the page suggests: he is now working the problem directly, and the fix is working.
Full eight bars, clean, pencil mark crossed out. What the sequence on the page suggests: time has passed, practice continued, the problem is solved.
Audience, applause, same passage performed. What the sequence on the page suggests: the work paid off.

Read without step 2, the sequence stops supporting its own ending: the clean eight bars arrive as an unexplained success. The drill is the cause, not a duration cue, so it cannot be dropped as repetition.

No caption. No dissolve to weather. The cause is on screen; the duration is not, and doesn't need to be. If the film later implies that a product produced this result within a particular interval, that implication leaves the editing conversation and goes to whoever holds the evidence. Compression is not a licence to claim speed of effect.

The point of reading cold is not to prove an audience understood — no one has shown this to an audience, and the boards don't exist yet. It is to check that the sequence is self-supporting on the page. If it survives without the writer's footnotes, it can survive a cut.

One last pass, in full, so the logic is visible in one place.

Before: He practises the passage, then we cut to the performance. A title card reads "six months later." The client likes the title card and asks why the character suddenly got good.

After: He practises the passage and stumbles on the fourth beat, marking the page. He isolates the fourth beat at half tempo. He plays it at tempo. The full passage, clean, the pencil mark crossed out. Cut to the performance. No title card.

Anchor: the room and the pencil mark. Changed condition: the hesitation, now absent. Preserved cause: the decision to slow down and isolate the beat. Omitted: the repetition, the interval, the badge of effort. Elapsed duration: real, unspecified, and no longer doing the work.

That is the whole method. Keep one thing the viewer can recognise, change one thing the film is about, and let the cause be visible before you cut. The clock is usually the least interesting thing in a time jump. It is almost never the thing that was missing.

Frequently asked questions

What is the difference between omitted duration and omitted causal action in a time jump?

Omitted duration means the viewer only needs to know that time has passed, and the later scene is fully motivated by what was already seen. Omitted causal action means the later scene rests on something that happened off-screen. The first is a transition problem: a cut, a fresh pour, or a moved chair can read. The second is a story problem: no dissolve repairs it, because the audience will wonder what they missed, and they did miss something that was not duration. Most broken time jumps in treatments are the second problem wearing the first one's clothes.

How do you make a time jump readable without changing everything?

Keep one recoverable anchor while changing a condition that matters. The anchor is what the viewer can still identify, such as a place, a face, a gesture, an object, or a routine. The changed condition is what the jump is actually about, such as the state of the pursuit, wear on an object, or the ease of a performance. Write both as an observable pair of moments. In the rehearsal example, the room and pencil mark anchor the scene while the hesitation changes from present to gone. Changing everything at once gives the viewer nothing to compare, and changing nothing that matters gives continuity without consequential change.

When can routine be omitted, and when must a causal event be planted?

Routine practice can be compressed or shown as a montage of the same bars at different hours. The difficulty still has to be shown at least once, or the later ease has nothing to contrast with. The decision that redirected the practice is neither routine nor difficulty; if the breakthrough depends on the performer choosing to slow the passage down and drill the fourth beat alone, cutting that choice leaves the audience watching a success they cannot account for. The repair is not a longer transition but a shorter film with a different sequence: bars, hesitation, pencil mark, the slowed bar alone, the same bar at tempo, the full passage clean, then applause.

Which transition cues work, and what are their limits?

Performance, wear or state of an object, environment, repeated action, sound, and explicit text are options, not a dictionary. Weather does not mean 'a month,' and a beard does not mean 'years' without help from the rest of the film. The test is what a cue actually conveys, not what it evokes. A costume change can mean overnight or a decade, which is fine if the interval does not need pinning down but a flaw if the proposition depends on 'after the treatment' or 'before the deadline.' In the rehearsal example, the pencil mark carries continuity, the crossing-out carries change, and the unchanged room carries the anchor.

What can this method not do?

The method can make a time jump legible, but it cannot make a timing claim true. If the later scene depends on a specific interval, such as an injury healing in a stated number of weeks or a product claiming a stated speed of effect, then the duration becomes a claim that needs evidence, not a title card. Compression is not a licence to claim speed of effect. Reading the sequence cold checks that it is self-supporting on the page; it is not proof that an audience understood, because no one has shown it to an audience and the boards do not exist yet.
