In-stream video ad scripts (skippable)

Quick Answer

In-stream Facebook video ads play inside other content the viewer is already watching. They are skippable, which means the only thing that matters is the first 5 seconds. If the viewer skips, the rest of your script never runs. Treat the 5-second window as the entire ad, then write the rest as a bonus.

The full script (scene by scene)

Product: A noise-cancelling earbud brand.

Scene 1 (0.0s to 5.0s) The 5-second skip armour

Visual: A creator on a tube train looks straight into camera. Background noise of the train is loud.

Audio: "I tested 14 earbuds on the Northern Line. This is the only one that worked."

Scene 2 (5.0s to 10.0s) Demonstration

Visual: Creator puts in the earbuds. Background noise drops to silence in real time. Audio editing makes the cut feel sudden.

Audio: "Listen to the difference. Same train, same carriage, three seconds later."

Scene 3 (10.0s to 16.0s) Mechanism

Visual: Pack shot, callouts pointing at chip and dual mics.

Audio: "It is a hybrid ANC chip with a wind reduction mic. No other brand under 100 pounds has it."

Scene 4 (16.0s to 22.0s) Proof

Visual: Three screen-recorded reviews.

Audio: "200,000 commuters bought a pair. 4.7 stars on Trustpilot."

Scene 5 (22.0s to 28.0s) Offer and CTA

Visual: Pack shot with price card. Discount sticker.

Audio: "Today only, 30 percent off the launch price. Tap below."

Why it works

The 5-second hook is the entire script in miniature. Notice the hook does three jobs at once: it is specific (the Northern Line), it is shocking (noise dropping out), and it is credible (testing 14). If a viewer is going to skip, the only thing that stops them is a hook that promises a payoff worth the click delay.

Scene two delivers on the hook immediately. This is the rule of in-stream: deposit before you withdraw. Most in-stream ads delay the demo until scene three, by which time the viewer has already skipped.

Common mistakes

Using a slow brand intro. The first 5 seconds is not the time for ambient music and a logo reveal.
Putting the CTA at second 4 thinking it will catch impulse clicks. It only catches skips.
Using a sound-off opener. In-stream is sound-on by default, so audio drives the hook.
Filming horizontal when the placement supports vertical and square. Vertical and square outperform 16:9 in-stream by 40 percent.
Treating the 28-second mark as a hard cut. Long in-stream can run to 60 seconds if the hook earns it.

FAQs

What is the minimum length for an in-stream ad?
15 seconds. Below that, Meta will not place it in mid-roll slots.

Can I reuse a Reels ad as in-stream?
You can, but it usually underperforms because Reels ads assume sound-off and in-stream assumes sound-on. Rewrite the audio.

What aspect ratio is best?
9:16 vertical, then 1:1 square. 16:9 horizontal is the worst for in-stream on Facebook and Instagram.

Should I show the price?
Yes, in scene five. Hiding the price increases clicks but tanks ROAS.

How many seconds does the average viewer actually watch?
Across our accounts, in-stream average watch time sits around 9 to 14 seconds. Build the script so the offer lands by second 12 if you want to catch the median viewer.
