Describe one change in a sentence and Promeo rebuilds the clip around it, so footage you already paid for can carry the next campaign.

In a hurry? Use the AI Video Edit by Chat quick guide instead.
Promeo's AI Video Edit by Chat changes what is inside a video you already have, working from one sentence you type. It covers a familiar gap: the footage is good, then the packaging changes. We swapped the bottle in a creator's hand for this month's serum, and her hands, face and room stayed exactly as they were.
The whole edit was this sentence: Replace the skincare product held in the video with the exact product from the reference image. Match the shape, color, label, and size accurately. Keep the person's hands, pose, face, background, and all other elements completely unchanged.
- In Promeo, open Video Edit by Chat under Video Toolkits and add your clip under Upload your Video.
- Type the change you want into the box beside it, in plain sentences.
- Attach up to five reference shots under Images, check the engine and output chips, then click the send arrow.
- Read Confirm Credit Usage and click Generate.
- Leave it rendering. Promeo notifies you in the app, and you can open another Video Edit by Chat tab meanwhile.
- Play the new cut back, then save it with the download icon.
Steps to Use AI Video Edit by Chat
Step 1: Open Video Edit by Chat and Load Your Clip
Start with footage that has already earned its keep: the creator clip that performed on one channel and now has to work somewhere else. Video Edit by Chat sits under Video Toolkits in Promeo's left rail, and it opens on a single instruction, upload your video and describe what changes you want to make. Click the panel under Upload your Video and pick the file. A thumbnail takes the place of the empty box, so you can see at a glance that Promeo has the right cut and not last quarter's export. Underneath, Choose a template lines up a wall of examples worth a scroll before you write anything.
Step 2: Say What Should Change, in One Sentence
This is the part that stands in for an afternoon of masking and tracking. Write the change into the box on the right the way you would explain it to a colleague.
Ours read: replace the skincare product held in the video with the exact product from the reference image, match the shape, color, label, and size accurately, and keep the person's hands, pose, face, background, and all other elements completely unchanged.
Look at it again and you'll see it is two instructions, not one. The first says what to change, the second lists what has to survive, and the second is the half people leave out.
Naming what should stay put is what keeps an expression or a room from quietly drifting while the product is swapped.
Step 3: Add the Product Shots It Has to Match, Then Send
A sentence can describe a change, but it cannot describe your packaging, so hand Promeo the real thing.
Click the plus tile marked Images and add up to five reference shots. We used three of the same serum: a hero shot lit on dark stone, a plain packshot on a neutral background, and a close-up of the dropper mid pour.
More angles give the job more to match, which is what makes your label come back looking like your label rather than a lookalike.
Each thumbnail is named @Image1, @Image2, and @Image3, and the example line in the box refers to one by name, so your instruction can too.
Before you send, check the two chips beside them: the left one picks which engine runs the job, and the right one sets the output at 1080p / Original. Then click the send arrow.
Step 4: Confirm What the Run Costs
Promeo does not spend anything without asking first. Confirm Credit Usage puts the cost of this job on screen before it starts, which is worth reading when you are making several versions of one clip.
Don't show again retires the prompt, Cancel backs you out, and Generate starts the render.
Longer video takes more out of your balance than short video, so a short cutdown is the sensible way to test your wording before you commit to a longer piece.
Step 5: Leave It Rendering and Line Up the Next One
The job takes a few minutes, and Promeo goes out of its way to tell you not to sit and watch it.
The tab turns into a Generating video tile, a notice at the top right confirms the task is processing and promises to tell you in Promeo when it is ready, and the line under the panel offers to open a new Video Edit by Chat tab.
Take it up on that. A repurposing session is rarely one edit: it is this clip with the new bottle, then the same clip with the other shade, then a version for the retailer who wants the carton in shot.
Running them side by side is the difference between an afternoon and a week.
Step 6: Play It Back, Then Download
When the job lands, the finished clip takes the place of the tile with a play button over it. Watch it once before you do anything else, and watch the parts you asked to keep rather than the part you asked to change: the hands, the eyeline, the light through the window.
The download icon in the corner saves the file. Look at the panel underneath as well: the clip in it is now the version you just made, so the next sentence you type builds on this cut instead of starting over.
Pressing play opens the Preview window, which puts the take you uploaded beside the version that came back on one set of playback controls, so you can check them against each other rather than from memory.
The Result
Here is the file that came back from one sentence and three product photos. Same model, same pose, same bedroom light, same five seconds. The only thing that moved is what she is holding, down to the shape of the dropper and the type on the label. That is a good trade for a marketing team, because the expensive half of a video, the casting and the location and the take where everything went right, keeps working while the thing you are actually selling changes underneath it.
