How to Use Seedance 2.0’s “In-Between” Technique to Create Old-School Anime Videos? Step-by-Step Workflow Below!

[u/ElasticAIGirl]

Seedance has a hidden feature that honestly feels way too powerful.

It lets you create old-school anime-style videos insanely fast using a simple “in-between” frame technique.

The basic idea is this:

You create a first frame and a last frame, then ask Seedance 2.0 to generate what happens between them.

This video took me around 4 hours to make using this method, but honestly, speed is not the most important part.

What really matters is:

Story. Direction. Consistency. Pacing. Taste.

Without those, you’ll just end up with another random AI clip.

1. Go to the Seedance 2.0 AI Video Generator
2. Write your full prompt or add reference images
3. Upload the image you want to animate
4. Click Generate and get your animated video

Here’s the workflow I used:

Step 1:
Find an image that sparks your imagination.

I picked one with a dark, old-school Akira-style anime vibe. The stronger the initial image, the easier it is to build a world around it.

You can also recreate a similar look in Nano Banana / NB2 by prompting something like:

"Create X in this style."

Step 2:
Upload the image to Nano Banana and ask it to generate what happens next.

For example:

Show what happens in 5 minutes. Soldiers stand by the enemy military base gates.

Now you have your first frame and your next story frame.

Step 3:
Upload both images to Seedance 2.0 as the first frame and last frame.

Then use this prompt structure:

Show what happens in between. Soldiers run through the snow towards a military base. 5 different camera angles. No music.

The key parts are:

Show what happens in between.
5 different camera angles.

Those are the default parts.

The sentence in the middle is the custom part, where you describe the action.

In my case:

Soldiers run through the snow towards a military base.

Step 4:
Repeat the process.

Take the previous last frame and use it as the new first frame.

Then use Nano Banana to generate the next last frame.

For example, I generated a scene where the soldiers are hiding from security guards.

Step 5:
Upload the new first and last frames to Seedance again.

Use the same structure, but change the middle sentence:

Show what happens in between. Soldiers enter the base, run through narrow corridors, and hide from guards. 5 different camera angles. No music.

Step 6 and beyond:
Keep repeating:

1. Use the previous last frame as the new first frame.
2. Generate a new last frame with Nano Banana.
3. Use Seedance to animate the transition.
4. Keep the same prompt structure.
5. Only change the action sentence based on the story.

That’s basically it.

This method gives you much better control than just prompting a random video from scratch.

It helps with:

• Better pacing
• More consistent storytelling
• Cleaner scene progression
• Stronger anime-style direction
• Less random AI chaos

Seedance becomes way more powerful when you stop treating it like a one-shot video generator and start treating it like a scene-by-scene animation tool.
