Can I add a photo of the new product?

Yes, on Seedance 2.5 and HappyHorse 1.0 (Video Edit). Gemini Omni 1.1 (Video Edit) and Runway Aleph 2 take words only.

How long can my clip be?

It depends on the model: 4 to 30 seconds on Seedance 2.5, and 3 to 10 seconds on Gemini Omni 1.1 (Video Edit). The clip tile shows the limit for the model you pick.

Do I have to write a prompt?

Not when a photo is in. Without one, or on a model that takes none, you describe the change in words. Words also help when the first run misses a detail.

Will the new product look exactly like my photo?

Material and colour followed the photo in our runs. The shape stayed close to the product already in the clip, and lettering on the original carried over. Check every result against the photo.

Preset: Miroge: recast your clip

Your clip

No words

With words

What you make, in order. Tap one to jump to its step.

You shot a clip you like, but one thing in it is wrong: last season's bottle, a placeholder prop, the old colourway. Miroge's Swap mode replaces that one thing and asks the model to keep the rest of the shot as you filmed it.

This guide follows one run from start to finish: a gold perfume flacon on a dark set becomes an emerald bottle from a single photo. Every clip here is real output, and the parts that did not change are said plainly.

Open Miroge and choose Swap

Open Miroge from the Create menu and choose Swap at the top. Recast on a video in your Library, or Miroge in the Studio timeline toolbar with a Library clip selected, opens Swap with that clip already in place.

Swap starts on Seedance 2.5. The Model menu under the prompt lists the other models that can run it. Miroge runs on Pro and Studio plans.

Add one clip that fits the model

The left tile, Your clip, takes one MP4 or MOV: Upload a file or pick one from your Library. Choose a shot where the product is clearly in view. If a clip does not fit the model, the composer says so and Generate stays off, so nothing is charged.

Model	Photos of the new product	Your clip	Result length
Seedance 2.5	Up to 9	4 to 30 s, up to 50 MB	Same as your clip
HappyHorse 1.0 (Video Edit)	Up to 5	Up to 15 s	You pick it
Gemini Omni 1.1 (Video Edit)	None, words only	3 to 10 s, up to 14 MB	Same as your clip
Runway Aleph 2	None, words only	Up to 10 s	You pick it

The Swap models when this guide was written. The clip tile always shows the current limits for the model you pick.

The source clip: a gold perfume flacon with a brass sphere cap stands on a black set, a burst of warm light flaring behind it — **Our clip.** Five seconds of a perfume flacon on a black set, made on NOLGIA with Gemini Omni 1.1 Flash for a product film. The bottle stays centred while a burst of light sweeps behind it.

Show the new product with a photo

On Seedance 2.5 or HappyHorse, press Add in the What goes in tile and choose Upload photos or From your Library. For a product you have saved, press Product instead: up to three of its photos and its description go with the clip.

With a photo in, the prompt is optional. Miroge's own instruction asks for the matching product to be replaced with the one in your photo, at the same position and scale, and for everything else to stay. See what gets sent, under the prompt, shows the whole instruction.

A perfume bottle of thick deep green faceted glass with a smooth matte black pebble cap, standing on a dark surface under a soft key light — **The photo we added.** Made with Nano Banana Pro for this guide: an invented, unbranded bottle.

Setting	What we used

What goes in	The photo of the emerald bottle
Model	Seedance 2.5
Quality	720p
Length	5 s, the clip's own length
Prompt	Off

The first Swap result: a green glass bottle with a grey pebble cap in the same burst of light on the same black set, the lettering from the original still on its front — **Made with Seedance 2.5** in Swap at 720p, with no prompt. The glass turned green and the sphere cap became a pebble. The bottle kept its own silhouette and its lettering, and the light, the set and the camera carried over.

Say more when the first run misses

Switch Prompt on and name what the photo should bring: the material, the colour, the shape, the cap, and what must not appear. Type @ to insert your photo as a chip. Your words lead, and Miroge's instruction follows them.

The line we added

Replace the gold perfume bottle with the emerald bottle in @Image1: thick deep green glass cut into sharp angular gemstone facets, a smooth matte black pebble cap, dark green liquid inside, and no lettering, label or logo anywhere on it.

The second Swap result: a darker emerald bottle with faceted edges and a pebble cap in the same burst of light, the lettering from the original still on its front — **Made with Seedance 2.5** in Swap at 720p, with the line above. The glass went darker and picked up facets, and the cap stayed a pebble. The silhouette and the lettering still came from the clip, not from the photo.

Watch for this:Lettering in the clip tends to stay. In both runs the name on the original bottle stayed on the new one, even though the photo has none and the words asked for none. If a label must go, shoot the product with the label turned away, or plan to remove it in Studio.

Read the result against your clip

Compare plays your clip and the result side by side. Check three things in this order:

The shot. Position, scale, the camera move, the light and the length should all match your clip. In our two runs they did: the bottle stayed centred, the light burst swept behind it at the same moment, and the clip came back at its own length.
The new product. Material and colour follow the photo well. Shape follows it less: the bottle kept the clip's silhouette in both runs. When the exact shape matters, pick a replacement with a similar silhouette, or expect to run it more than once.
Anything that should not be there. Lettering, logos and marks from the original can carry over. Look for them before you use the clip.

These are two runs on one clip, not a measurement. Every run is a new render, so read yours the same way.

Or describe it in words

Gemini Omni 1.1 (Video Edit) and Runway Aleph 2 take no photos, so the change is in words and the prompt is required. Words work on the other models too: leave the photo tile empty. Name the product that goes and where it is, then describe the new one by its material, colour and shape. The composer's example is replace the red mug with a matte black steel bottle.

Watch for this:Plan the sound. Gemini Omni 1.1 (Video Edit) makes a new soundtrack, and Runway Aleph 2 returns none. If your clip's sound matters, lay the original back under the result. For a longer film, swap one shot at a time.

What it costs

A model that keeps your clip's length is priced on that length, rounded up to the second, and the exact price is on the Generate button. Every Swap model needs Pro or above, and topping up does not unlock them on a lower plan. Clips of well known people and copyrighted material are refused, and a refused run gets its credits back.
