Pin the launch post, with the video in it, the minute it goes up. Keep it there until the replies stop. Then swap it for something newer.
Here's why. Most launch-day visitors don't come from your launch post. They see your name under a reply, or in a bigger account's quote, and tap through to your profile. X shows them your pinned post first (X Help). For most of the people who find you during a launch, the pin is the launch.

Copy these and swap in your product. The example, Ledgerly, is a fictional invoicing tool.
The waitlist pin, two to six weeks before launch:
I'm building Ledgerly: invoices that chase themselves, for freelancers who hate asking twice.
Launching in March. Here's the 30-second version. Join the list: [link]
The launch pin, on the day:
Ledgerly is live.
Send an invoice, and it follows up for you until it's paid.

Free for your first 10 invoices: [link, here or in the first reply]
The proof pin, a few weeks later:
Three weeks since we launched Ledgerly. The thing people asked for most was partial payments, so it ships today.

Each one does three things: says what the product is in a line, shows it, and gives one link.
Link in the post or in the first reply? Our launch guide puts the launch link in the first reply, since whether X cuts reach for links is disputed. But someone viewing your pin from your profile sees the post, not the replies, so put the same link in your bio's website field. For the waitlist and proof pins, which aren't chasing launch-hour reach, keep the link in the post.
Wording and line breaks for the launch post itself are in our guide to writing a launch tweet.
If you launch with a thread, pin the first post. That's what visitors see, so it has to work on its own: the video and the link go there, not in post seven. A thread that opens with a hook like "we spent a year on this, here's what we learned" makes the visitor do work. Most won't. Our launch thread template puts the product in post one for this reason.
The pin decides whether a visitor gets past your name. The video decides whether they get past the pin. The hard bit isn't editing. It's picking the one scene that makes a stranger get the product.
That's what we do at Flowjam. Our story-driven launch videos have averaged over 100,000 views with no media budget. See how we'd make your launch video.
To unpin, use the same menu on the pinned post and choose Unpin from profile (X Help).
You get one pin. Pinning a new post replaces the old one. Paid accounts also get a Highlights tab on their profile where they can collect several posts (Gulf News), but visitors have to tap into that tab to see them, so it doesn't replace the pin.
You can't pin someone else's post. That matters more than it sounds. Rork's launch video spread from another builder's account twelve days after launch (TechCrunch). If that happens to you, write a post of your own that quotes theirs, with your link, and pin that.
Don't delete your launch post and post it again to get a fresh start, either. Posting the same thing over and over to push it is the kind of thing X's platform manipulation rules cover, and you lose the replies you already had.
Change it when its job is done, not on a schedule. Rules we'd follow:
Whatever is pinned, your bio, banner and website field should point at the same thing. X allows 160 characters of bio and recommends a 1500 by 500 banner (X Help). Room for one line about the product and one image of it. The rest of launch day, from timing to the first hour of replies, is in our guide to launching on X.

A post you fix to the top of your X profile, so it's the first post anyone visiting your profile sees. You can have one at a time.
No. One pin per profile; pinning a new post replaces the old one. Paid accounts get a separate Highlights tab for collecting more, but visitors have to open that tab to see them.
As long as it's still drawing replies or quotes, usually the first week or two. Then swap it for a newer post that shows what's changed.
No, you can only pin your own posts. Quote their post with a line of your own and your link, and pin your quote.
Yes: one line on what the product does and for whom, the video, and one link. The three templates above (waitlist, launch and proof) all follow that.
Yes, one. Visitors who reach your profile have already shown interest, so give them a single place to go rather than several.
