Editing

One reaction, three edits: a timing breakdown

The same expression can introduce a question, bridge into an action or punctuate a result. The timeline decides which job it does.

The useful bit

The tables below are edit recipes, not three finished campaign exports. The playable example shows a reaction followed by a product demonstration.

A compressed sample from the library

Hover or tap to see the motion. This is source footage, ready to combine with your own demo. Paid members can browse and download the originals.

What comes with a clip

Read the source before trimming it

Watch the reaction from beginning to end. Find the moment before the expression, the moment it becomes clear and the point where it begins to settle. Those are more useful landmarks than an arbitrary clip length.

In the public demonstration, the reaction leads into a product recording after three seconds. That makes the sequence easy to inspect. In your own project, choose the cut point around the source movement and the time needed to read the line.

Edit A: question first

Use the expression to introduce a specific question. Keep the line short and remove it as the product takes over. The demonstration must answer the question without an unrelated transition.

Suggested timePictureText decision
0–0.5sLead into the expressionLet the viewer find the face
0.5–2.5sThe expression becomes readableOne short question
2.5–8sThe matching product actionRemove the opening line
8–10sA settled resultOptional next step

Edit B: result first

Start with the product’s finished state, then use a brief reaction to bridge into how it happened. This puts the evidence up front. Keep the reaction short enough that it does not feel like a detour from the promised explanation.

Suggested timePictureText decision
0–2sThe actual resultName what changed
2–3sA brief part of the reactionNo second competing headline
3–8sThe action that produced the resultOnly an essential instruction
8–10sReturn to the finished stateA relevant next step

Edit C: a quiet cutaway

Let the product begin the story. Insert a small reaction after the useful action, then finish on the result. The face behaves like punctuation rather than a dramatic promise.

Try this when the result is practical but not surprising. It can also help when the opening interface is already clear and adding a question would repeat what the viewer sees.

Suggested timePictureText decision
0–5sThe product actionName the task if needed
5–6.5sA short settled expressionKeep the face clear
6.5–10sThe visible resultLeave enough reading time

Compare the meaning, not just the pace

Watch each rough cut without sound and write what it seems to say. A face placed before a reveal creates anticipation; the same face after it can imply satisfaction. Check that the latter does not become an unsupported claim about the source creator’s personal use.

These structures change more than a single frame or word. If you compare them, treat them as complete editing approaches. To isolate caption wording, keep the structure and source timing fixed.

  • The cut lands on a readable part of the expression.
  • The hook has a visible payoff.
  • Text does not compete with the product controls.
  • The source person is not presented as an unverified customer.
  • The ending remains clear in the exported file.

Watch the sequence

The reaction introduces the idea; the screen recording shows the action. This is an editing demonstration, not a customer result.

Hover or tap to play. The final edit starts with the reaction, then cuts to the demo.

Questions & answers

Are these exact timings required?

No. They are storyboard timings. Adjust them to the source movement and the time needed to understand the product.

Why not keep the reaction visible throughout?

A continuous overlay can make sense if both sources remain readable. A direct cut often gives a dense app interface more space.
