Seedance 2.0 AI Short Drama Tutorial: 4 Ways to Solve Character Consistency and Story Coherence

During the May Day holiday, I had two free days and created videos of Xiang Yu’s Battle of Wujiang, a One Piece cosplay, and a tea TVC…

I used the killer combo of GPT-image2 + Seedance 2.0.

Honestly, Seedance is incredibly powerful right now — director-level thinking + storyboard breakdown + one-sentence-to-video. Stack these three capabilities, and even beginners can produce decent-quality work.

But the tricky part is that each generated video is only 15 seconds long. If you want to create a continuous video, like a 1-minute short film, it gets a bit troublesome.

The common approach is to first build an asset library — character three-view images, scene images, props, etc. — and use character assets to control video generation. But even then, you’ll run into issues like continuity errors and incoherent plot.

Through my own practice, I’ve figured out four methods.

Today, let me share some of my insights and pitfalls when making medium-length videos.

1. Extend with Reference Video

This approach yields the best results — directly extending the video based on the original clip.

You have the first video segment; what do you do if you want to continue filming?

How to use: Upload the original video as a reference, then extend the story further.

Command: Extend 15s video, using the original video’s character appearance, generate a new plot: [input subsequent script]

Seedance 2.0 supports video extension, and most importantly: it maintains character consistency.

This was a short drama Xingzhe made when Seedance first launched. I composited a 30-second short. Of course, with a script, you can keep building on it.

The character appearance stays consistent, the plot seamlessly connects, and you don’t have to worry about sudden style changes.

For those making narrative short films, this means you can extend your story infinitely, like building blocks.

When generating images in LibTV, there’s a neat feature: push forward 3 seconds or pull back 5 seconds, which you can use together.

But one downside is that uploading video references consumes a lot of credits, and Jimeng hasn’t fully opened video reference yet. Tools like XiaoYunQue and LibTV support it.

2. Use a Keyframe as the First Frame

This method is quite common.

Take a keyframe from the end of the first video and use it as the first frame reference for the next video.

This allows the story to continue while maintaining consistent style and scene coherence.

For example, in this tea TVC ad I made, the initial segmented videos felt noticeably disjointed when combined.

The main scene transitions went from urban office → tea mountain → back to office.

I then screenshotted the final frames of several videos and used them as the starting frames for the next shots.

Of course, it’s good practice to prepare ahead before making any short drama:

Character three-view images, scene images, prop images — get all these ready in advance, and the rest of the workflow will go much more smoothly.

3. Composite Multiple Video Segments

This is probably the most conventional method.

With a complete storyboard + a good script, generate each 15-second storyboard video separately, then composite them in editing software like CapCut.

For this xianxia concept video, I planned each shot sequence in advance, just like releasing a game trailer.

From game login → NPC dialogue → summon teammates → scene exploration → leveling up and defeating monsters → boss battle.

The resulting video feels quite complete.

Of course, you need to think like a director — plan out the function, rhythm, and emotion of each shot ahead of time.

4. Convert Storyboard Images to Video

This technique was originally developed by nano.

When I made “Zootopia” and “POP girl group,” I used this logic.

First, based on the main character, use reference images to generate storyboard frames, then generate videos from those frames.

There’s another method: After GPT-image2 came out, generate a storyboard, then directly use Seedance 2.0 to create a 15-second video.

Image2 prompt: Generate a high-end product TVC ad storyboard, 2 rows 3 columns six-panel contact sheet, aspect ratio 16:9, each cell is cinematic ad-level composition, thin white borders separating the six frames, no text, subtitles, logos, or watermarks.

This technique is especially useful for storyboard previews, or quickly creating demos to validate story scenes.

Finally, My Honest Thoughts

After playing with these tools for a few days, I’m increasingly convinced of one thing:

AI video has moved from generating a single beautiful shot to organizing a complete narrative.

These two stages are completely different.

Before, when we played with AI video, we focused on:

• Is this shot stunning?
• Is this character beautiful?
• Does this image look cinematic?

But now, the truly valuable questions are:

• Can the story continue?
• Can the character stay stable?
• Can the shots transition smoothly?
• Can the emotion progress?
• Can the audience understand?

That’s also why I’ve always said: At the end of the day, AI video creation isn’t just about tools — it’s about director-level thinking.

Seedance 2.0 is powerful. GPT-image2 is powerful.

The more powerful the tool, the more it tests human judgment.
