Vidu

The hardest part of AI video isn't getting a pretty clip. It's getting the same character to look like themselves from one shot to the next. You generate a great five-second scene, then the next one gives your hero a different face, a different jersey, or an extra arm. Vidu is built around fixing that. Its headline feature, Reference to Video, lets you hand it a reference image and tell it to treat that subject as the sole character. The demo prompt on vidu.com asks it to keep the player's face, helmet, red jersey, football and red smoke consistent across a 10-second, 16:9 sequence with three hard cuts.

That demo prompt shows how Vidu wants you to work. You don't just describe a vibe. You script it shot by shot: a close-up from 0 to 3 seconds, a low-angle tracking shot from 3 to 7, a frontal medium shot to finish. You also direct the audio: footsteps, breathing and distant crowd noise, no music, no subtitles. Around that core you get Image to Video, Text to Video, Text to Image, an AI Sound Effect Generator, a template library, and Vidu Agent, which claims to take you "from a single sentence to a complete work." There's also a real-time model pitched with millisecond response, plus an API platform and enterprise plans for teams.

The testimonials are worth reading because they're more specific than the marketing copy. Several creators, many of them Japanese anime makers, single out facial expressions and subtle character acting as Vidu's strength, and one says the Q3 model with audio costs just 6 credits per 5-second clip, which let them iterate far more. The catch is that the product copy is vague in places, and the pricing page didn't load any plan details in our source, so you'll be signing up to learn exactly what the freemium tier gets you. If character consistency and expressive animation are your bottleneck, it's one of the more focused options out there.
