Change a cover after posting

The cover on a Reel is editable after publication, and almost nobody does it. That makes cleaning up your existing grid one of the few genuinely retroactive fixes in social media — an afternoon spent on posts you already made, collecting views you already earned the impression for.

How to change it

1. Open the Reel on your profile.
2. Tap the menu (the three dots) and choose Edit.
3. Tap the cover thumbnail. You can either scrub to a different frame of the clip or upload an image from your camera roll.
4. Save. The still updates on your grid and everywhere else it appears.

The written caption, tags and audio are editable in the same place. The video itself isn’t — if the clip needs re-cutting, that’s a new post.

Why old posts are worth the effort

Feed distribution is a one-time event: your clip is shown, and it’s over. Your grid is the opposite — it keeps being seen, by every person who taps your name from now on. Those visitors arrived at the highest-intent moment in the funnel, and they’re deciding on still images alone.

Which means a good cover on a four-month-old clip is still working this week. That’s the closest thing to free distribution the platform offers, and the argument is laid out in full in Your cover is doing more work than you think.

Which posts to redo, in order

1. The first nine. What a visitor sees without scrolling. These decide the follow.
2. Anything still getting traffic. A clip that’s still being served is still sending people to your profile.
3. Your best content with your worst cover. The mismatch that costs the most: a genuinely good clip nobody taps.
4. Anything with a mid-blink face. The auto-picked frame is chosen to be representative, not persuasive.

Stop there. The bottom two-thirds of your grid is not where the return is.

What to replace them with

• Two to five words, large. If it isn’t legible at 120 pixels wide, it isn’t on the cover.
• A face with an expression. Not mid-word. Not mid-blink.
• Everything inside the centre square. The grid centre-crops a 9:16 cover to roughly 3:4, so anything near the top or bottom of your design does not exist on your profile — the numbers are in the safe zone guide.
• The same treatment across all of them. One accent colour, one headline font. Nine covers that share a look read as a body of work; nine unrelated frames read as someone posting.

Doing it as one batch

The reason this gets postponed is that it sounds like nine separate design jobs. It isn’t, if you treat it as one:

1. Decide the treatment once — typeface, accent colour, where the headline sits.
2. For each post, pull the headline from the clip itself. The strongest line in the video is almost always the right cover text, and it keeps the promise honest.
3. Generate or grab the frame, set the text, export.
4. Upload all nine in one sitting, then look at the grid as a whole and adjust.

That last step matters more than any individual image: the grid is read as a set, and it’s only judgeable as a set.
