Thank you for your interest. So first, we need a reference image. You can actually create this using any AI. But if you need to do it for a specific product, you should use Flux Kontext Max — it will place your product into a new image as realistically as possible.
The prompt I used for this image is:
"Create an ultra-realistic, high-resolution photo of a human hand holding a large, sharp kitchen knife poised to cut a small, fully detailed and scaled-down realistic bicycle placed precisely on a wooden cutting board; the bicycle should appear 100% real with accurately represented metal, rubber, and plastic materials, featuring the brand name clearly visible and intact as a real printed logo, all set in a natural kitchen environment with natural lighting and a shallow depth of field for enhanced realism."

Then, you’ll need to use Google Veo 3. You can start with the free one-month trial. It's easy to use — but the hard part is finding the correct prompt.
For the normal bike cutting video, I used:
"Ultra-realistic close-up of a human hand holding a sharp knife slicing directly through a bike. The knife visibly cuts and slices the bike itself into multiple segments and layers, showing internal electronics, plastic elements, and circuit boards inside. The bike is being cleanly and slowly sliced apart by the blade in smooth, deliberate motions. The video should look like the knife is slicing through the bike as if it were soft enough to be cut, revealing detailed internal components. Include subtle mechanical slicing sounds synchronized with the knife movement for immersive effect. There should be only one scene."

For the cake version, I used:
"Ultra-realistic close-up of a human hand holding a sharp knife slicing directly through a bike. The knife visibly cuts and slices the bike itself into multiple segments and layers. As the knife progresses, the sliced parts of the bike begin to resemble the soft, spongy texture of a layered cake — almost like the entire bike was made of cake disguised as a machine. Crumbs and soft frosting-like textures subtly appear where the knife passes, blending realism with surreal softness. The bike is being cleanly and slowly sliced apart by the blade in smooth, deliberate motions. The video should look like the knife is slicing through the bike as if it were soft enough to be cut, revealing detailed internal components. Include subtle mechanical slicing sounds synchronized with the knife movement for immersive effect. There should be only one scene."

You should convert these prompts to fit your specific product by using ChatGPT.
For that, you can say:
"Please change this prompt for my '[product]', making sure the general structure of the prompt doesn’t change — just make it suitable for '[product]'."
