Summary

The author shares character movement issues encountered when creating AIGC with Seedance 2.5, introduces Higgsfield's open-source K-pop action series "Zephyr: Special", and summarizes key techniques for writing prompts.

I've recently been trying to create AIGC with Seedance 2.5, but the fluidity of character movements has been troubling me. I found several common issues: 1. Spatial direction easily gets confused. 2. After camera cuts, overall coherence is lost. 3. Characters and props tend to move around. Just when I was confused, I came across an open-source AI action series called "Zephyr: Special", which has been extremely helpful in solving the above problems. The series is worth $1 million in total and reached over a million views within hours of release, but now it has been open-sourced by Higgsfield. I studied its prompts carefully and found that the key to creating good character movements lies in: 1. Make the space clear first. Where the character enters from, which direction they face, where they move to, and which side of the character the camera is on — all of these need to be determined before the action happens. 2. There needs to be a relay between shots. Each cut continues from the existing state, so the character and actions naturally connect. For example: if in the previous shot the character raised a hand, the weapon landed in a certain position, or the body stopped in a certain pose, the next shot should continue from there. 3. Characters, props, and the camera need to follow the same set of motion relationships. For example: when a character charges forward, clothes, hair, and props in hand should follow the body's inertia; when the camera moves, the distance between background and character should also change in sync. I strongly recommend friends who are making AIGC to study the prompts of this open-source project in detail. The video below is one of the action clips — isn't it impressive? Fluidity of movement, fight scenes, and attention to detail are all maxed out. Thank you very much to Higgsfield for the open-source spirit, saving us a lot of time!!!!

I’ve recently been experimenting with Seedance 2.5 to create AIGC content, but character motion fluidity has been a constant headache. I keep running into a few common problems:

  1. Spatial orientation easily gets confused 2. Overall coherence is lost after camera cuts 3. Characters and props tend to drift around

Just as I was scratching my head, I stumbled upon an open-source AI action series called Zephyr: Special, which has been incredibly helpful in solving these issues. The series is valued at $1,000,000 in total and racked up millions of views within hours of release — and now Higgsfield has open-sourced it.

After carefully studying its prompts, I found the key to crafting great character motion lies in:

  1. Establish the space first. Where the character enters from, which direction they’re facing, where they’re moving, and which side of the character the camera is on — all of this needs to be locked in before the action happens.

  2. Camera cuts need to pass the baton. Every cut should build on the existing state and move forward from there, so the character and action connect naturally. For example: if the previous shot had the character raising their right hand, the weapon landing in a certain spot, or the body stopping in a specific pose, the next shot needs to continue from that.

  3. Characters, props, and camera must follow the same system of motion relationships. For instance: when a character lunges forward, their clothes, hair, and handheld props all need to follow the body’s momentum; when the camera moves, the distance between the background and the character needs to shift in sync.

I strongly recommend that anyone working on AIGC dig into the prompts of this open-source project. The video below is one of the action sequences from it — pretty mind-blowing, right? The fluidity of the motion, the fight choreography, and the level of detail are all dialed to the max.

Huge thanks to Higgsfield for their open-source spirit — they’ve saved us so much time!!!!

Higgsfield AI 🧩 (@higgsfield_ai): Zephyr: Special, the new episode of our K-pop action series, featuring @hay_nyash, is open-sourced for the $1,000,000 Higgsfield Global Film Festival.

Every prompt and asset is now public – Seedance 2.5 pushed to the max.
