Seko

When short video creation was still a high-threshold activity requiring skills in editing software, scriptwriting, and multi-stage coordination, SenseTime’s launch of Seko, the world’s first all-in-one AI short video creation Agent, shatters these barriers with its “natural language input → fully automated workflow → professional-grade output” closed-loop capability. Whether a novice user describes a “sci-fi short, robot protagonist + space scene” or a film studio needs to batch-generate product promotion videos, Seko uses its large model intelligent agent to handle the entire workflow—from scriptwriting and art direction to voiceovers, music scoring, and storyboard drawing—making “everyone a short video creator” a reality.

1. Core Positioning: From “Assembling Multiple Tools” to “Fully Automated Creation-Editing Integration,” Redefining Short Video Creation Logic

What sets Seko apart from standard editing tools or single-function AI generators is its product positioning as a “Full-Process Intelligent Agent.” Built around the core principle of “users provide the idea, AI handles the rest,” it establishes three key advantages:

1.1 End-to-End Automation: One Agent Handles “Idea to Final Video”

Seko completely moves beyond the traditional model of “writing scripts in Word, drawing storyboards in PS, editing in Pr, recording audio in AU.” A single Agent covers all stages:

• Requirement Parsing → Scriptwriting: A user inputs “Tell the history of the Terracotta Army in CG style, 1-minute duration.” Seko first parses the core requirements (Theme: Terracotta Army history; Style: CG; Duration: 1 minute), then automatically generates a structured script, including a three-act structure (“Opening shot: panoramic view of the army → Development: recreating historical scenes → Conclusion: summarizing cultural value”), complete with dialogue, shot descriptions, and timing.
• Art Direction → Storyboarding: Based on the script’s style, the AI automatically matches CG art assets (e.g., bronze color palette, realistic modeling) and generates corresponding storyboard panels (e.g., “Shot 1: Top-down view of the pit, slow camera push-in, VO: ‘In 221 BC, the Terracotta Army was created…'”). Panels include scene elements, character actions, and camera angles.
• Voice & Music → Final Rendering: Matches voice tone to the script (e.g., a deep male voice for historical themes) for auto voiceover; selects background music based on scene mood (e.g., epic orchestral). Finally, it composites storyboards, voiceover, and music into the final video without manual assembly. Feedback indicates a historical explainer video that previously took 2 days can now be produced in about 30 minutes with Seko, matching team-produced quality.

1.2 Character Consistency: Ensuring Image Uniformity for IP-Based and Series Content

A major pain point in character-driven videos is “character inconsistency between shots” (e.g., changing hairstyle, clothing color deviations). Seko addresses this with SenseTime’s proprietary character consistency algorithm:

• Character Import/Creation: Users can upload IP character images or create characters via natural language description (e.g., “a cartoon cat with pink hair, wearing overalls, lively expression”). The system generates a character feature library (including parameters for hairstyle, clothing, facial details).
• Cross-Scene Image Locking: Whether generating multi-scene scripts or batch-producing series videos, Seko references the feature library to ensure the character’s appearance (hairstyle, clothing, proportions) remains consistent across all shots, even down to expression details.
• Style Adaptation Without Drift: Even when switching video styles (e.g., from 2D cartoon to 3D modeling), core character traits are preserved, maintaining recognizability. An IP team reported 98% character consistency across 10 videos using Seko, with fans noting they “looked official.”

1.3 Natural Language Interaction: “Zero-Learning-Curve” Operation for Beginners

Seko lowers the interaction barrier to “if you can talk, you can create,” supporting natural language instructions throughout:

• Simple Idea Input: Use everyday language, no technical terms needed (e.g., “Teach how to make pour-over coffee, warm style, 1.5 minutes long”). The AI extracts key info automatically.
• Flexible Editing: After generating a draft, use natural language for edits (“Swap the BGM for a light piano track,” “Make the space scene bluer,” “Add robot dialogue emphasizing ‘protecting humanity'”). The AI identifies the request and updates the video in real-time, no manual timeline/parameter tweaking.
• Intuitive Function Access: To use features like the “Inspiration Hub” or “Character Library,” just say “Suggest some short video themes for children” or “Create with the Chou Chou Mokoko character.” The system responds directly, avoiding complex menus.

2. Function Matrix: A Professional-Grade Toolkit for the Entire Creation Workflow

Seko’s functions are designed around the complete short video lifecycle: “Idea Input → Content Generation → Editing Optimization → Export/Share.”
