Video Description is an example of an agent your team can build in Sylvie: hand it a finished cut and it writes the title options, the description, the timestamped chapters, the tags and the pinned comment, sized for YouTube, LinkedIn, Instagram or wherever the video is going. It runs on your brand brain, so the CTA, the product links, the required disclosures and the keywords you actually want to own are already correct on the first draft. You assemble the agent once, and it writes the metadata for every video you ship after that.
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 Description is one of the agents a video or content team assembles in Sylvie, not something we hand over finished. It takes the file you just exported and produces everything that surrounds it on the platform: a few title options, the description copy, timestamped chapters, keywords and hashtags, the pinned comment and the CTA, plus a variant sized for each channel it is going to.
Metadata is the part of video every team treats as an afterthought and then wonders why the view count is flat. A great edit with a two-line description and no chapters is a video the algorithm cannot place and a viewer cannot skim. An agent built on your brand brain writes that layer properly on every upload, so the library you already paid to produce starts earning views instead of sitting there.
Give the agent the cut, the transcript or just the file. It reads the whole thing, then pulls the rest from your brand brain: the client's tone of voice, the claims that are cleared, the live offer, the link and UTM structure, any disclosure line the brand has to carry, the keywords it is chasing, and how your best-performing descriptions were written. Everything it reads is permission-aware and scoped to that brand, so one client's links or claims never end up under another client's video.
Then it drafts inside Sylvie: title options, a description that lands the hook in the first 150 characters, chapters pulled straight from the transcript, tags and hashtags, a pinned comment and the closing CTA, then trims a version for each destination and its character limit. You review, approve and publish in the same place, and the edits you keep sharpen what the next upload starts from.
Metadata stops being the reason a finished edit sits in a folder for a week. A cut that lands at 4pm can be titled, described, chaptered and live before anyone goes home.
Every description carries the phrasing and search terms the brand is actually trying to rank for, taken from the brain rather than guessed. Videos start pulling views from search and suggested, not only from the launch push.
Timestamps and chapter titles come from what was actually said, with no scrubbing the timeline to mark them. Viewers jump straight to the part they came for, and watch time follows.
Product URLs, tracking parameters, disclosure lines and the current offer come from the brand brain, not from a copy-paste of last month's video. No expired promo or dead link goes live under a new upload.
The same video gets a YouTube description, a LinkedIn post, an Instagram caption and a blurb for the site embed, each inside its own limits. You stop pasting one paragraph into four boxes that all want something different.
Point the agent at everything already published with thin descriptions and it rewrites them in bulk. Two years of back catalog becomes searchable without re-editing a single frame.
A description agent pays for itself anywhere video ships on a schedule and is judged on views nobody paid for. Here is where video and content teams point one they have built.
A brand publishes an episode every Thursday and the description is always written in the last ten minutes before it goes up. The agent turns the final cut into titles, chapters, tags and a CTA the moment it exports, so the episode ships on time with metadata that holds up in search instead of a placeholder nobody goes back to fix.
One hero video needs a YouTube description, a LinkedIn post, an Instagram caption and a copy block for the product page. The agent writes all four from the same cut, with the same launch messaging and the correct link per channel, so the rollout happens in an afternoon rather than across three days of handoffs.
A client's channel has 180 videos with one-line descriptions, no chapters and dead links to a retired offer. The agent rewrites them against the brand brain in bulk, and a dormant library starts pulling organic views and sending traffic to pages that still exist.
A performance team ships thirty video variants a month and each one needs its own copy, disclaimer and tracking link. The agent generates the set per variant with compliance wording already in place, so the media buyer spends the day uploading instead of writing.
A financial services brand requires a specific disclosure and approved claim language under every video. The agent writes descriptions that already carry the cleared wording from the brain, so compliance signs off in one pass instead of sending three rounds back.
A studio publishes video for ten brands, each with its own voice, link structure and keyword set. One agent, pointed at each brand's own brain, writes every description in the right voice, so the team adds channels without adding a copywriter per client.
Neither one knows your offer, your link structure, your required disclosures or the terms you are trying to own, so you rewrite the output anyway. This agent drafts from your brand brain, which holds all of that, and hands you a description that is already correct. You are editing a finished draft rather than assembling one from parts.
The video file, the edit export or a transcript all work: it will transcribe when there is no transcript, and it reads the whole thing before writing a word. If you also give it the campaign or the brief, it will tie the description to that messaging rather than just summarizing what was said.
No. Sylvie does not sell a pre-built Video Description product. This page is an example of an agent you assemble in Sylvie, built on your own brand brain and your own publishing workflow, so it matches how your channels actually go live.
The brain holds tone of voice, approved claims, product facts, the live offer, link and tracking conventions, required disclosures, target keywords and the descriptions that performed well. The agent reads all of it on every draft, so metadata stays current as offers and positioning change instead of going stale inside a saved template.
That is the point of building the agent rather than buying one. You define the sections, the chapter style, the keyword approach, the CTA and the character target per platform, and when the brand brain changes, every future description changes with it. The same build can serve one channel or a whole roster.
Each brand's brain is isolated and permission-aware, so an embargoed launch film or a client's keyword strategy never surfaces in another account. The agent reads only what you allow, and drafts stay inside your workspace until you decide to publish them.
