About Vidu Q4 Preview
Vidu Q4 is the next-generation flagship from ShengShu Technology (the team behind the Vidu model family), released as a public preview on October 7, 2026. Its focus is coordination: facial expression, emotion, body movement and generated audio stay locked together — from a quiet glance to full action. On fal's API it generates up to 16 seconds at up to 4K from reference images.
On img2.video you get it through the same simple workflow as every other model: one photo, one prompt, clean MP4 out. We expose image + prompt generation with an optional native-audio toggle. For a deeper dive, read our Vidu Q4 Preview guide — features, pricing and how it compares to Kling 2.6 and Veo 3.1.

Vidu Q4 FAQ
What is Vidu Q4?
Vidu Q4 is ShengShu Technology’s next-generation flagship AI video model, released as a public preview on October 7, 2026. It animates images with tightly coordinated facial expression, emotion, body movement and native audio, in clips up to 16 seconds and up to 4K.
What makes Vidu Q4 different?
Three things together: 16-second clips (most models stop at 8–10s), native audio — dialogue and sound effects — at no extra cost, and resolutions up to 4K with strong character consistency across the clip.
How much does Vidu Q4 cost?
On img2.video, Vidu Q4 starts at 30 credits for a 5-second 720p clip. 1080p, 4K and longer durations cost more — the exact price is always shown before you generate. Audio is free on every tier.
Is Vidu Q4 stable? It says Preview.
Preview means ShengShu may tune the model as feedback comes in — outputs can vary week to week. Pricing on img2.video stays fixed, and if a generation fails your credits are refunded automatically and instantly.
Does Vidu Q4 support voice references or voice cloning?
No — img2.video deliberately exposes image + prompt generation only, with an optional native-audio toggle. We do not offer voice-clone inputs, in line with our Acceptable Use Policy on impersonation.
Vidu Q4 vs Kling 2.6 vs Veo 3.1 — which should I pick?
Vidu Q4 for the longest clips (16s) and free audio; Kling 2.6 for cinematic motion per credit; Veo 3.1 for maximum polish in 4K. Your 30 free sign-up credits cover one clip on any of them — try all three.
