Repurpose Content for Social Media: One Asset, Every Format

You have one good asset. A hero video of the product that finally landed, or a single image that took nine tries to get right. The idea is done. Then the second job starts: the vertical cut for Reels and TikTok, the square one for the feed, the wide one for YouTube, captions burned in because most people watch on mute. None of that is creative work. It is a tax you pay on every good idea.

Repurposing content for social media with AI is supposed to remove that tax. Most tools only half remove it: they hand you a crop tool and a subtitle editor, and you still do the work yourself, just in a browser tab instead of an app. Kubeey, the AI media agent inside Kubeez, takes a different route. You describe the format you need in plain language, in the same conversation where the asset was made, and it comes back sized.

New here? Start with what Kubeey actually is, then come back.

The reformatting tax nobody budgets for

Count the versions that one campaign asset really needs:

That is four renders, plus a captioned version of anything with speech in it. The traditional path is to shoot or generate once, then spend an afternoon in an editor pushing the subject back into frame, because a 16:9 hero center-cropped to 9:16 cuts the head off.

The conversation-first path is shorter, and it is mostly about knowing what to ask for.

Start with one source asset

Everything below assumes one thing: a source you actually like. There are two ways to get there.

Generate it in the conversation. Ask for the hero, iterate until it is right, and stop when you would be happy to post it. Writing that first brief well is its own skill, and the first post in this series covers the brief and the plan card that confirms the cost before anything runs.

Upload your own. Real footage from a phone or a camera works too. Ask to bring in a local file, Kubeey hands you an upload slot, you drop the file in, and it becomes something the conversation can work on. Your asset, the agent's hands.

Either way, from here on there is exactly one source. That is the whole point.

Ask for the reframe, do not crop it

This is the part worth understanding, because it is where the quality comes from.

Every image and video generation on Kubeez carries an aspect ratio. It is not a post-processing step bolted on at the end. It is an input, decided before the pixels exist.

So the vertical version of your hero is not a crop of the wide one. It is the same scene, rendered again, composed for a tall frame. Nothing important gets chopped, because nothing was ever laid out for 16:9 and then squeezed into a phone.

What you say:

Nice. Now give me that same shot as a 9:16 for Reels, keep the brewer centred, and leave room at the top for a headline.

What you get back is a vertical render of your scene, built for the shape it will be watched in. You can hand Kubeey the original as a reference so the subject, the lighting and the styling carry across instead of drifting into a different-looking product. Keeping a whole set visually consistent is its own topic, and the second post in this series goes deep on brand references and personas.

There is also regenerate, which re-runs a previous generation with overrides. That is the low-effort path when the only thing changing is the shape:

Regenerate that last one at 1:1.

Same prompt, same styling, new frame. No re-briefing.

The 4:5 detail that gives it away

Ask for the Instagram feed portrait and you quickly find out whether a tool actually knows social media. 4:5 is a real spec, and not every image model can physically render it. Ask Kubeey for 4:5 and the job gets routed to a model that can, rather than handing you a 1:1 and calling it close enough.

Small thing. It is the kind of small thing that separates a tool that knows the platforms from a tool that knows rectangles.

The video cuts: trim first, caption second

Video has two more moves, both handled server-side, both things you ask for rather than do.

Trimming. The 40 second hero becomes the 12 second opener:

Trim it to the first 12 seconds.

Captions. Kubeey transcribes the speech and burns word-timed captions into the video itself. Burned in, not a sidecar subtitle file that a feed will quietly ignore. Three real constraints are worth knowing before you fire it:

That last one matters more than it sounds. Auto-detect is fine for clean English narration. If your voiceover is Romanian or Spanish, say so, and the transcription gets noticeably better.

If captions are the entire job rather than one step inside a bigger one, there is a dedicated auto-captions tool that skips the conversation entirely.

Kubeey knows the platform specs. It does not know your password.

This section is the useful part and the honest part at the same time.

Kubeey knows real per-platform limits, and it will tell you before you build something that will not fit:

So when you say "make me a carousel of the twelve product angles for Instagram," you get told it is ten, not twelve, before twelve images are generated and two are thrown away. Knowing the spec is a budget feature as much as a formatting one. Every image you do not need to generate is credits you keep.

Now the boundary, stated plainly, because a lot of marketing in this category is slippery about it:

Kubeey cannot post, publish or schedule anything to any social platform. There is no account connection, no scheduler, no one-click publish. Knowing that a TikTok title caps at 90 characters is not the same as holding the keys to your TikTok account, and Kubeez does not ask for them.

What you get is a ready-to-post file, correctly sized for the platform you named. The last step stays yours.

Reviewing without opening every file

Four cuts of the same asset means four things to check, and opening each one in a new tab defeats the point.

Kubeey can look at up to eight images at once and answer a question about them:

Look at these four. Which one reads best as a thumbnail at phone size?

You can also pull up what you have already made, so a conversation you started on Tuesday is still useful on Friday:

What did we make for the launch last week? Show me the vertical ones.

This is the quiet half of repurposing. Generating four formats is easy. Finding them again a week later is where most asset libraries fall apart.

The handoff is yours, on purpose

The whole loop, honestly stated:

  1. Kubeey generates. One source asset, then each format sized on request.
  2. You review. On screen, in the conversation, before anything leaves the building.
  3. You save. Download the cuts you want.
  4. You post. From your account, on your schedule, with your caption.

Step four being manual is not a gap waiting for a roadmap item to fill it. It is where a person is supposed to be. Nobody actually wants an agent holding their credentials and firing content into the world unattended, and the moment a tool offers that, it is asking you to trust a model's taste more than your own.

So: one asset in, every format out, and a human at the door. You can start a conversation with Kubeey with an asset you already have, or read what else it can do first. If you want the tour before you talk, the Kubeey overview is the short version.

Frequently asked questions

Can Kubeey post my videos to TikTok or Instagram for me?

No. Kubeey generates the assets and sizes them for the platform you name, but it cannot post, schedule or publish to any social platform, and it does not connect to your accounts. You download the finished cut and post it yourself.

Does Kubeey crop my existing video down to 9:16?

No, and that is deliberate. Kubeey renders the vertical version at the aspect ratio you ask for rather than cropping a finished wide file, which is why the subject does not end up half out of frame. Trimming changes the length of a clip, not its framing.

Do I have to write a new brief for every aspect ratio?

No. Ask to regenerate the last output with a new ratio, and the prompt and styling carry over. You only re-brief when the creative changes, not when the shape does.

What are the limits on burned-in captions?

The video must be 30 minutes or less, and it needs actual speech in it: silent clips come back with "no speech detected". Language is auto-detected, and naming the language yourself unlocks higher-quality per-language modes.

Can I use my own footage instead of generating it?

Yes. Ask to upload a local file, drop it in, and the trimming and captioning steps work on your own footage. Reframing is a re-render, so it applies to assets generated in the conversation rather than to a video you uploaded.

How many images can I put in an Instagram carousel?

Ten. Kubeey knows the cap and will tell you before it generates an eleventh, which saves the credits you would have spent on images that were never going to fit.
