Creating consistent character videos with Veo 3.1, GPT-4o, and Google NanoBanana

This n8n template demonstrates how to create consistent character videos using AI image and video generation. The workflow generates photorealistic videos featuring the same character across different poses, locations, and outfits, maintaining perfect character consistency throughout cinematic transitions.

Use cases are many: Create consistent character content for social media, generate cinematic videos for brand campaigns, produce lifestyle content with the same character, automate video content creation for TikTok/Instagram, create character-based storytelling videos, or scale video production with consistent visual identity!

Good to know

- The workflow maintains perfect character consistency across frames using reference images - Uses multiple AI services: GPT-4o for prompt generation, Google Nano Banana Edit for image generation, and Veo 3.1 for video creation - Features 100 unique locations (beaches, cities, cafes, rooftops, etc.) and 15 different poses - KIE.AI pricing: Check current rates for Veo 3.1 and Nano Banana Edit models - Processing time: ~5-10 minutes per complete video (depends on AI service queue) - Output format: 9:16 aspect ratio videos optimized for TikTok/Instagram - Automatically generates social media content (titles, descriptions, hashtags) using GPT-4o - Includes AI disclosure labels for TikTok compliance

How it works

1. Location & Pose Selection: Randomly selects one location from 100 options and 3 unique poses from 15 options 2. AI Story Creation: GPT-4o generates cinematic prompts for first frame, last frame, and video motion while maintaining character identity from reference images 3. Start Frame Generation: Google Nano Banana Edit creates the first frame image with character in initial pose, location, and outfit 4. End Frame Generation: Nano Banana Edit generates the final frame using start frame as reference, changing only pose/expression while maintaining consistency 5. Video Generation: Veo 3.1 creates smooth cinematic video transition between frames with natural character movement 6. Content Creation: GPT-4o generates engaging title, description, and hashtags for social media 7. Auto-Publishing: Automatically posts to TikTok (with AI disclosure) and Instagram, plus sends previews via Telegram

The workflow ensures the same character appears in both frames with identical facial features, hair, skin tone, and overall appearance, while only pose and expression change. The video features dynamic camera movements (arc shots, dolly pushes, crane rises, etc.) for cinematic quality.
