TL;DR
Reference to video AI locks a character's identity across multiple scenes using a single reference image or video. Tools like Flixly's Reference to Video dashboard use models such as Seedance 2.0 and Kling 3.0 to maintain AI consistent character features, expressions, and clothing in outputs up to 1080p at 10 seconds per clip. This eliminates redraws, cuts production time by 70%, and delivers character consistency video for ads, shorts, and series without manual editing.
Reference to video AI fixes character drift in generative video. Upload one reference image video of your subject, and models hold their look through scene changes. Flixly's Reference to Video tool runs frontier models like Seedance 2.0 and Kling 3.0 for results in under 2 minutes per 5-second clip.
What Is Reference to Video AI
Reference to video AI takes a source image or clip—your reference image video—and generates new video scenes where the character stays identical. No morphing faces or shifting outfits. Models analyze facial structure, body pose, clothing texture, and lighting from the reference, then bind it to prompts for new actions.
This beats basic text-to-video, where characters regenerate per frame. Expect 95%+ identity retention on good references. Flixly processes at 512x512 to 1080p, 5-15 seconds output, costing 15-45 credits per generation.
Core Mechanics
- Feature Extraction: Model pulls 500+ keypoints from reference (eyes, hairline, scars).
- Binding Layer: Locks traits to prompt via latent space anchoring.
- Frame Propagation: Ensures consistency over 120+ frames.
Why Character Consistency Video Matters
Inconsistent characters kill viewer trust. A hero's blue eyes turn brown mid-scene? Audience drops off. Reference to video AI delivers AI consistent character output, vital for:
- Marketing: Same brand mascot across ad sequences.
- Shorts/Series: Recurring roles in TikTok or YouTube.
- Storytelling: Protagonists that persist through plot twists.
Numbers show impact: Videos with locked characters get 40% higher retention (YouTube Analytics 2026 data). Production skips 5-10 hours of rotoscoping per minute of footage.

Step-by-Step Workflow
- Prep Reference: Use AI Image Generator or Image to Image for a clean 512x512+ portrait. FLUX Kontext excels here for base consistency.
- Upload to Tool: Drag reference image video into Reference to Video. Supports PNG/JPG/MP4 up to 10s.
- Craft Prompt: "Character runs through forest, dynamic camera, sunset lighting." Strength slider: 0.7-0.9 for tight bind.
- Select Model: Seedance 2.0 (best multi-angle, 25 credits/10s) or Kling 3.0 (cloth/hair detail, 35 credits/10s).

Frequently Asked Questions
What is reference to video AI?▾
Reference to video AI uses a source image or clip to generate new videos where the character's appearance stays locked across scenes. It analyzes key features like face shape and clothing to maintain identity. Flixly's tool supports this with models like Seedance 2.0 for quick, consistent outputs.
How does character consistency video work?▾
Character consistency video binds a reference image video to new prompts, ensuring the AI consistent character doesn't change. Models extract and propagate traits frame-by-frame. Expect 95%+ fidelity on 1080p clips up to 15 seconds.
Best model for reference image video on Flixly?▾
Seedance 2.0 leads for multi-reference support and 97% consistency. Kling 3.0 follows for dynamic motion. Both run in Flixly's Reference to Video dashboard at 25-35 credits per 10-second clip.
Reference to video AI vs text to video?▾
Reference to video AI locks characters from a provided image, fixing inconsistencies in text-to-video outputs. Text alone regenerates subjects randomly. Use reference for series or ads needing the same face.
Cost of AI consistent character generation?▾
Flixly charges 15-45 credits per 5-15 second clip, depending on model and resolution. 1000 credits cost $19 monthly. Most users hit 5-10 generations per dollar.
Can reference to video AI handle multiple characters?▾
Yes, Wan 2.7 excels with multi-subject references. Upload separate images for each, and it binds them together. Great for group scenes or battles.
Fix character drift in reference to video AI?▾
Lower binding strength to 0.6-0.7 and match prompt lighting to reference. Use shorter clips or iterate with Video to Video. Seedance 2.0 minimizes drift best.
