The video gen that actually preserves your character

Vidu is the AI video generator from Shengshu Technology (a Tsinghua University spinout) that solved the multi-subject consistency problem. Where Kling, Sora, and Runway lose your character's face, hair, or outfit across shots, Vidu's 'Subject Reference' feature lets you upload up to 3 reference images and the model maintains those exact subjects in different scenes, angles, and motion. It's also one of the fastest video models — 16 seconds of 1080p in under 90 seconds.

Who it's for: Storytellers, animators, ad agencies that need to keep the same character across multiple shots, and anyone building a multi-clip narrative. Great for anime and stylized content, good enough on photorealism.

Key features

Ref Multi-subject reference

Upload 1-3 reference images. Vidu preserves the exact same character (or characters) across different scenes, angles, lighting, and motion. The only major model that actually nails this for video.

16s Long clips, 1080p

16-second clips standard on all paid plans, 1080p output, 24fps. Longer than Sora's 20s free tier limit and Runway's 10s Gen-4. Great for narrative shots that don't need stitching.

Fast Sub-90s render

One of the fastest video models in the industry. 16s of 1080p renders in under 90 seconds, vs 3-5 minutes for Sora or Runway. Batches of 10 clips practical for production.

2.0 Vidu 2.0 model

Released Q1 2026, Vidu 2.0 adds 4K output, improved motion coherence, native audio generation (music + SFX matching the prompt), and a video-to-video style transfer mode.

The honest take

✓ What works

Best multi-subject consistency in the industry — no other model does this well
Fastest video model for 1080p output
Longer clips (16s) than most competitors
Free tier is genuinely useful (10 credits/day, 720p)
Strong on stylized content (anime, illustration, 3D)

✗ What doesn't

Photorealism lags Sora and Veo for product/lifestyle work
4K only on Premium tier ($30/mo)
Less polished UI than Runway or Sora
Some Western users report payment friction (credit card acceptance)

Verdict

If you need character consistency across multiple video clips, Vidu is the only model that actually delivers in 2026. Sora wins on photorealism, Runway is the pro's pick, Kling is the budget option, Pixverse is best for stylized. But for narrative video with the same character in multiple scenes, Vidu is unmatched.
