Five rough pen sketches became moving video characters with AI tools

A vampire, a mummy, a mad scientist clown, a girl next door and a secret agent, carried from paper sketches to video.

This student took five hand-drawn sketches, one of them labelled simply "idk", and turned each into a full character that moves on video. Using what they learned from Domenic, they built a clear, repeatable workflow with ChatGPT and Higgsfield. It shows how far a rough idea on paper can travel once you know the steps.

5 sketches into animated video avatars

Before

They started with five pen sketches on paper, loose and scribbled. One horror figure was so unformed they wrote "idk" beside it. The characters lived only as ideas on a page.

“Used learnings from Domenic to turn 5 sketches into a video avatar.”

In their own words

The turning point

Learnings from Domenic gave them a method. They fed photos of each sketch into Higgsfield and kept refining until a full body image appeared, then used ChatGPT to write prompts for Higgsfield's AI Influencer Studio tool.

After

Each of the five characters now has an outfit starter kit, a headshot and a 3 x 3 grid of full body views made with Nano Banana Pro. With Higgsfield's Motion Control tool, they brought all five to life in video: the female vampire, the female mummy, the mad scientist clown, the girl next door and the secret agent.

What it lets people do

The workflow lets anyone with a sketch turn it into a consistent character that can be shown from every angle and animated. The headshot and full body grid keep the character looking the same from shot to shot.

What they learned

Refining step by step matters more than starting with a perfect drawing. A rough sketch, a well-written prompt and patience were enough to build a cast of characters.

“Continued to refine until full body image created.”

Read the full submission
Used learnings from Domenic to turn 5 sketches into a video avatar. Tools used with Chat GPT and Higgsfield with steps as follows: 1. Analyse photo of sketch to Higgsfield to generate each character. Continued to refine until full body image created. 2. Used Chat GPT to generate prompts for Higgsfield's AI Influencer Studio tool for each character. 3. Used Nano Banana Pro in Higgsfield to create outfit starter kits for each character. 4. Used Nano Banana Pro in Higgsfield to create headshot and 3 x 3 grid of fully body image for each character. 5. Used Higgsfield's Motion Control tool to create videos with these characters. - The female vampire: https://higgsfield.ai/s/E7oT308YmIg - The female mummy: https://higgsfield.ai/s/tB1TogwKHq0 - The mad scientist clown: https://higgsfield.ai/s/P0rUdQtpgt8 - The girl next door: https://higgsfield.ai/s/i2DVT4u6EKk - The secret agent: https://higgsfield.ai/s/YUlmB9MieO0
