Vidu Models: The Essentials

Vidu is a high-end AI video generator developed by Shengshu Technology that transforms text, images, or multiple reference frames into richly animated, 24fps cinematic clips. Unlike standard tools, Vidu focuses on expressive performances, stable motion, and advanced temporal consistency.

Scenario currently offers two primary model families: the Q3 Series, designed for maximum fidelity and durations up to 16 seconds, and the Q2 Series, optimized for speed and complex character consistency.

Model Comparison

1. The Vidu Q3 Series: Cinematic Excellence

The Q3 Series (available in Pro and Turbo variants) is the definitive choice for professional creators who require longer narrative clips and the highest possible visual fidelity.

• Extended Durations: Generate seamless cinematic sequences ranging from 1 to 16 seconds.

• Narrative Control: The Image-to-Video (I2V) workflow supports Start/End to Video conditioning, allowing you to upload the first and last frames to precisely dictate the movement's evolution.

• High-Definition Output: Supports native 1080p resolution across diverse aspect ratios, including 16:9, 9:16, 1:1, 4:3, and 3:4.

• Pro vs. Turbo: Choose Pro for maximum micro-acting and motion quality, or Turbo for a performance-optimized workflow that delivers high-quality results at higher speeds.

2. Vidu Q2 Reference2V: The Consistency Expert

The Q2 Reference2V model is a specialized tool designed to solve the challenge of character and asset consistency in AI video.

• Multi-Image Reference: Upload up to 7 distinct images to serve as visual anchors for the AI.

• Asset Lock: Vidu cross-references these images to ensure that character faces, intricate props, or specific costumes remain identical from the first frame to the last.

• Production Specs: Supports high-quality 1080p output with a maximum duration of 10 seconds, perfect for character-driven action sequences or product demonstrations.

3. Standard Vidu Q2 Series: Speed & Versatility

The standard Q2 family (including Pro, Turbo, and Pro Fast variants) provides a reliable and fast framework for high-impact short content.

• Advanced Frame Control: Much like the Q3 series, the Q2 I2V models support Start/End to Video conditioning. This allows you to upload both a first and last frame to precisely guide the motion and composition of your 10-second clip.

• Flexible Tiering: Choose between Pro, Turbo, and Pro Fast versions to balance generation speed and visual detail according to your project's needs.

• Efficient Workflow: Optimized for durations up to 10 seconds, these models are perfect for social media assets, rapid prototyping, and iterative motion testing.

• Full Resolution Support: The entire Q2 family supports professional 540p, 720p, and 1080p resolutions.

Key Strengths Across the Vidu Family

• Micro-Acting and Expression: Vidu models (especially the Pro tiers) capture natural blinks, subtle facial shifts, and organic-feeling movement.

• Cinematic Camera Language: The models respond to complex cinematography terms like "dolly-in," "low-angle tracking," and "sweeping pan".

• Audio Integration: Most Vidu models include native audio generation, creating synchronized ambient soundscapes or background music.

Prompting Guide & Best Practices

• Think Like a Director: Define the Subject, Action, Environment, and Camera Angle.

  • Example: "Cinematic low-angle shot of a fantasy warrior leaping over a chasm, high-fidelity motion, sunset lighting, 1080p."

• Use the First Frame: For best results in I2V, generate a high-quality character image first and upload it to the First Frame slot to lock in the visual identity.

• Leverage Multi-References: When using Q2 Reference2V, provide different angles of the same character (front, profile, back) to help the AI understand the 3D volume of the subject.

• Control Motion with Duration: Use the Duration Slider to set the exact length (up to 16s for Q3, up to 10s for Q2) to match your narrative timing.
