How to Make Viral Videos with Seedance 2.5

Seedance 2.5 is one of the craziest "nano banana moments" of AI VIDEO in 2026.

It's the model behind every viral video that you are seeing right now...

and it's pretty simple to generate those video, it takes one prompt only fr...

It's one of the best models for ultra-realism and crazy camera control, even though most people are still using it to produce slop.

I will show you how to do this literally in 2 mins, without yapping, without making you subscribe to a platform that lures you into a yearly plan lol...

p.s. if you see an AI GURU doing a promoted post on X, you should know that they aren't making money with their methods loool.

Step 1: go to Seedance 2.5 on kie ai

If you don't know what Seedance 2.5 is, it's ByteDance's latest AI video model where you can use video and image references for advanced video generation and video editing.

We will use the Seedance 2.5 model from the platform that charges you based on clear pricing, not making you subscribe to a plan.

It's one of the best and MOST EXPENSIVE modern video models right now.

You can do this on any platform that has Seedance 2.5. Kie ai is just the one that doesn't trap you in a yearly plan.

Step 2: find a viral video and download it

What I like to do is go on TikTok and find a viral video I want to clone.

It doesn't matter whether it's TikTok, Reels, YT Shorts, whatever. Just download it.

Once you download the video, cut it to the supported length and upload it to Seedance 2.5 as Video1.

This video will act as the editing master. Seedance will use its camera framing, movement, actions, gestures, timing, lip movements, shot transitions, and event order.

That's the whole point. You're not generating a video from scratch. You're stealing the thing that already got the views.

Step 3: generate your unique character

Next, generate your own unique character.

We don't want to use real people for the videos unless you actually have the rights to those people.

Generate a clean character image. Face, hair, wardrobe. One person. Your avatar.

Upload that character to Seedance 2.5 as Image1, next to your base video.

Image1 is only the character. Nothing else.

use this prompt for character sheet with gpt 2.5:

1Exactly. Keep the face visible only in Column 1. Use this correction in the prompt:
2
3Column 1 is the only panel where the character’s face is visible. Show a large chest up front portrait with the full face clearly visible, sharp eyes, pale blue irises, broad square jaw, prominent nose, large toothy grin, thick eyebrows, and tall swept back pompadour.
4
5Column 2 shows the same character full body from the front, but crop the composition so the head is completely outside the top edge of this panel. Start the visible body at the base of the neck and continue down to the shoes. Preserve the exact blazer, tie, trousers, proportions, clasped hand pose, and body build. Do not generate a second face anywhere in this panel.
6
7Column 3 shows the same character full body from the back. His head may remain visible only from behind so no facial features are visible. Clearly show the back of the pompadour hairstyle, blazer construction, dark elbow patches, trouser fit, posture, and shoes.
8
9Important composition rule: exactly one visible face in the entire reference sheet, located only in the large left portrait. No duplicate face, no second frontal head, no profile face, no reflected face, no facial features in either right panel.
10
11The final sheet should therefore read as one large identity portrait on the left, one neck down front body reference in the center, and one full back body reference on the right.

Step 4: the prompt. that's it lol

Now you guys may be wondering how you make a prompt with Seedance 2.5.

If you just try to prompt it normally by saying "replace the person in the video with my character," you're usually going to get inconsistent identity, changed background, different clothing, broken movement, or random changes to the original video.

This is usually where most people give up and say Seedance 2.5 doesn't work.

Use this exact prompt:

1Reference Image1 for the character only.
2
3Replace the old man in Video1 with the character in Image1, make sure to keep everything else the same.
4
5also make sure the color grading is correct and matches the original video.

That's all you have to write.

The most important line is "keep everything else the same."

This tells Seedance 2.5 that it should not regenerate the entire scene from scratch. It should inherit the original video's framing, movements, actions, timing, lip movements, and shot sequence while only replacing the person.

"Reference Image1 for the character only" stops it from pulling the background, lighting, or composition out of your character image.

The color grading line stops it from washing the clip and making it look like a different video.

Your prompt is consistent because every uploaded reference has one clearly defined job.

Video1 is the viral video. Image1 is the character. Nothing else changes.

Yeah it's this easy.
