Seko — SenseTime Gave Everyone with an Idea Their Own AI Film Crew

The hardest part of making videos isn't coming up with ideas. It's everything that comes after.

Writing storyboards. Recording voiceovers. Hunting for assets. Tweaking lip sync. Stitching clips together in editing software. The picture in your head is already crystal clear, but the moment you think about opening four or five different tools, you're already tired.

SenseTime's Seko was built to solve exactly this.

Launched in August 2025, Seko is positioned as a "multimodal short film creation Agent" — which, in plain terms, means it doesn't just generate video clips for you to stitch together. It handles the entire pipeline from script to finished film. You bring the idea. It does the work.

One Sentence In, a Finished Film Out

Here's where Seko separates itself from other AI video tools: most of them work as "type a prompt, get a clip, assemble it yourself." Seko works as "type a sentence, get a finished video."

You just describe what you want to shoot in natural language — something like "Labubu dancing enthusiastically in a Spanish restaurant" — and it automatically breaks down the story logic: who's the main character, what's the setting, how many shots, what pacing, what music. Then it runs through the whole pipeline: script creation, art style definition, storyboard drawing, voiceover, and music.

No prompt engineering required. No platform switching. That's the core gap between Seko and most AI video tools on the market.

Capabilities That Actually Solve Problems

AI Director. No screenwriting knowledge needed. Describe your idea, and Seko generates a complete script — it even figures out what each shot should capture and how the pacing should flow.

Character Consistency. Once you import or create a character, Seko keeps that character looking the same across every storyboard and scene. Anyone who makes comic series or short dramas knows how big a deal "character drift" can be.

Natural Language Editing. Want to change something? Just say it in the chat box — "make the art style anime," "give me a close-up on this shot," "swap the background music for something more intense." It responds instantly. No control panels to learn.

Multi-Model Orchestration. Text-to-image, image-to-video, lip-sync generation (Seko Talk, supporting Chinese, English, and Japanese), storyboard planning — these modules are all integrated under the hood. The Agent automatically dispatches the right model for each step. You never have to worry about which tool handles which环节.

Where It Shines

• Short drama creation: generate a complete script from one sentence, or upload an existing script for analysis. Fast mass production with diverse styles
• Product promotion: upload a product image and auto-generate multiple versions of product intro videos — ideal for e-commerce teams
• Short video creation: produce videos through conversational editing, zero experience needed
• IP character fan-creation: character consistency keeps the look uniform, letting fans build stories and scenes around an IP

The Honest Take

Seko's approach is the right one — it shifts the hard part of creation from "operating tools" to "expressing ideas." As long as you can describe what you want clearly enough, it can make it happen. The visual editor is also well done: you edit the final result, not intermediate steps, so every change shows up directly on screen.

That said, AI video still breaks where you expect it to. Complex scenes occasionally have physics and logic issues. Also, it currently requires invitation-based registration — signing up grants you creation credits, but full membership pricing hasn't been publicly detailed yet. If you want to use it seriously, you'll need to wait for the official open launch.

Bottom line: if you make short dramas, comic series, or product promo videos, Seko is worth trying. It's backed by SenseTime's large model infrastructure, not some white-label shop operation.
