Video Ad is an example of an agent you can build in Sylvie: give it a product, an offer and a placement, and it returns complete ads (the two-second hook, the beat-by-beat script with timings, shot or screen notes, captions for sound-off viewing and the end card) in the durations and aspect ratios you actually run. It works from your brand brain, so it pulls the offer that is live this week, the claims legal cleared and the hooks that already delivered on this account, not a generic idea of your category. Sylvie assembles the agent on your own memory, there is no pre-built version to switch on.
Sylvie does not ship this agent pre-built. It is an example of an agent your team can build with Sylvie, powered by your brand brain, so it runs your workflow the way you actually run it.
Video Ad is one of the agents a paid team or agency can build on Sylvie. Ask it for a concept set and it writes finished ads rather than ideas: hook variants built to earn the first two seconds, the script beat by beat with timings, on-screen text, the caption track, a shot list or screen-recording plan, and an end card carrying the offer and CTA, delivered in the durations and ratios each placement needs.
Paid video dies from creative supply. The account needs a fresh batch every fortnight, the buyer can test far more than the studio can produce, and the concepts that get made are the ones somebody had time to write rather than the ones the data pointed at. An agent built on your brand brain closes that gap: the volume comes from the agent, the judgment stays with your strategists.
Before writing, the agent reads the brand brain for that account: the product facts and the offer running right now, the claims and disclaimers legal has cleared plus the ones it has banned, the tonal and visual rules for the brand, the platform policies that apply to the category, and the performance history of which hooks, angles and lengths actually won and which fatigued. Each brand's memory is isolated, so one client's winning mechanic or margins never inform another's ads.
Then the build runs inside Sylvie. It generates a structured concept set (angle by hook by format) instead of six versions of one idea, writes each ad to its placement and duration, checks claims and the character count on the end card, cites the source behind every number, and hands the pack to your strategist to approve, cut or regenerate. Approved ads and their results flow back into the brain, so the next batch starts from firmer ground.
The agent opens with the patterns that have actually held attention on this account, not a slow brand intro. Paid video is won or lost in the first beat, so it drafts for that first.
Six, fifteen and thirty second cuts in 9:16, 1:1 and 16:9, each rewritten for its format instead of cropped. The buyer receives a full placement set rather than one asset stretched to fit.
Only cleared claims, required disclaimers and category-safe language reach a script. Far fewer ads bounce back from legal or get disapproved by the platform, which is media time you keep.
A structured matrix of angles and hooks gives the media team genuinely different bets to read. The test tells you which message works, not which edit was slightly tighter.
Captions, on-screen text and a visual story that lands muted are written in from the start, because most of the feed will never hear your voiceover.
Every ad that performed leaves its mechanic in the brand brain, so the next batch builds on proven structure. Your best creative becomes a repeatable asset instead of a lucky month.
A few of the moments where a Video Ad agent, built on your brand brain, earns its place in the paid workflow. Every one is creative your team would otherwise be writing between status calls.
The buyer wants twelve genuinely different concepts to read and the creative team has capacity for four. The agent drafts the full matrix (four angles across three hook styles, each with its cuts) from approved messaging, so the test plan goes into production on Monday instead of being trimmed to fit the calendar.
Frequency is climbing and the ad that carried the account for six weeks is losing efficiency. The agent produces fresh executions that keep the mechanic that worked and change the hook, the setting and the opening line, so you rotate in proven structure before cost per acquisition drifts rather than after.
A concept that prints on Meta needs a TikTok version and a straight repost will fall flat. The agent rewrites the pacing, the opening and the on-screen text for how people watch there while holding the claims and offer intact, so the channel test launches in days with real creative.
The client swaps twenty percent off for free shipping and every live video ad now says the wrong thing. The agent reissues the affected voiceover lines, on-screen text and end cards across the running set in one pass, so the account is accurate the same day and no spend goes to an expired promise.
The same concept has to work for someone who has never heard of the brand and someone who abandoned a cart last week. The agent writes both cuts from the same angle, shifting the level of explanation, the proof and the CTA, so each stage gets purpose-built creative instead of one ad shown to everybody.
In supplements, finance or health, half the copy dies in review. Because cleared claims, required disclaimers and banned phrasing sit in the brand brain, scripts arrive pre-checked and cited, so review becomes a sign-off and the batch reaches the platform in one round rather than three.
It builds everything production needs: hooks, the script with timings, on-screen text, captions, shot or screen-recording direction and the end card, ready for your editor, your creator roster or your generative tools. When you build the agent you decide how far into production it carries the work.
A generic model writes a plausible ad for your category. This agent writes for your account: the offer live right now, the claims your legal team cleared, the disclaimers you have to carry and the hooks that already delivered on this brand. Every element cites where it came from, so a strategist reviews instead of fact-checking.
No. Video Ad is an example of an agent teams build in Sylvie on top of their own brand brain. You define the placements, the durations, the concept matrix it works to and the review steps, so it produces creative in your house style rather than an off-the-shelf format.
That is what makes it compound. When results flow back into the brand brain, the agent knows which hooks, angles and lengths performed on the account and reaches for those patterns first, so the fifth batch is far better informed than the first.
You load the category rules and each platform's restrictions into the brain and the agent drafts within them, avoiding the personal-attribute phrasing and unsupported claims that trigger disapprovals. It is not a legal review, it is a first draft that arrives much closer to compliant, with a human approving before launch.
You build a version per brand, each on its own isolated brain, so one client's offers, margins and winning creative are never visible to another. New accounts inherit the workflow you already built and start producing testable creative in their first week.
