Vidu Q3: Text & Image to Video Online
Bottom line
Vidu Q3: Shengshu's flagship, up to 16s with native audio, 720p/1080p, from 40 credits. Start from a prompt or a still image in the Text to Video tool; VdoBloom shows the exact credit cost before each Vidu Q3 run, with no separate Vidu account.
Vidu Q3 is Shengshu's flagship Vidu model and the longest single take on VdoBloom's Vidu line: 5-, 8-, or 16-second clips, with audio generated together with the picture in every render. That combination changes what one generation can be — a short scene with sound design, a talking beat with ambience, or a product moment with an audio bed can come out of a single prompt instead of a video-plus-separate-audio-pass workflow.
It accepts text prompts or reference images, outputs 720p or 1080p, and frames at 16:9, 9:16, or 1:1. Pricing runs 40 credits for 5 seconds at 720p up to 145 credits for 16 seconds at 1080p: 40/63/125 credits at 720p for 5/8/16 seconds, and 45/70/145 credits at 1080p for the same durations.
Q3 carries a 3.9 rating and MODERATE content filtering — standard, not the strictest tier. The Q3 Turbo sibling shares the exact same spec sheet at roughly half the price, trading some quality headroom for speed. New accounts start with 10 free credits.
What it costs on VdoBloom
40/63/125 credits at 720p for 5/8/16 seconds, and 45/70/145 credits at 1080p for the same durations. Audio is included in every price — there's no separate charge for sound. Cost is shown before you generate, and a failed render is refunded automatically. New accounts start with 10 free credits.
Vidu Q3 vs Seedance 2.0 and Kling 3.0
Against Seedance 2 (82 credits flat, 5s/720p, no audio), Q3's 40-credit 5-second clip is cheaper and includes sound. Against Kling 3.0's per-second billing (5.6-26.8 credits/s depending on tier and sound), Q3's flat-rate table becomes more predictable at longer durations, especially at the 16-second length neither Kling 3.0 nor Seedance 2 match on VdoBloom. The tradeoff is resolution ceiling: both alternatives reach higher (4K) than Q3's 1080p cap.
Common problems and how to avoid them
Online discussion around Vidu Q3 tends to focus on how it holds up against other action-scene and long-take models — a fair comparison point given its 16-second ceiling, but worth testing against your specific prompt rather than assuming length alone guarantees a better result. Because audio generates with the video, a mismatched or unwanted soundtrack means regenerating the whole clip rather than just the audio track; keeping the prompt specific about tone (quiet, energetic, ambient) reduces mismatches. As with every VdoBloom model, the cost is shown before you generate and a technical failure is refunded automatically.
What creators use Vidu Q3 for
- Scene-length 16-second clips with generated sound, avoiding a stitch-three-clips-together workflow.
- Social videos that ship straight from generation because ambience and effects are already in the file.
- Image-anchored shots where a reference frame sets the look and Q3 adds motion and audio together.
- Action-heavy sequences that need a longer single take than most video models offer.

Frequently asked questions
How long can a Vidu Q3 clip be?
Up to 16 seconds, with 5- and 8-second options for shorter beats — the longest single duration in the Vidu family on VdoBloom.
How much does Vidu Q3 cost?
40 credits (5s/720p), 63 credits (8s/720p), 125 credits (16s/720p), 45 credits (5s/1080p), 70 credits (8s/1080p), and 145 credits (16s/1080p).
Does Vidu Q3 really generate audio, not just video?
Yes — it's multimodal, so sound is generated together with the picture in every render, arriving in sync rather than needing a separate audio pass afterward.
Is Vidu Q3 free?
New accounts get 10 free signup credits — a quarter of the cheapest 40-credit render. Beyond that, generation is paid, with the exact cost shown before you confirm.
Does Vidu Q3 allow more mature or NSFW content?
No — VdoBloom rates its content filter MODERATE, meaning standard filtering, not a permissive HOT tier. Explicit material is refused regardless of how the prompt is phrased, and VdoBloom's own moderation applies on top of the provider's filter.
Vidu Q3 vs Seedance 2.0 — how does pricing compare?
Seedance 2 (bytedance/seedance-2) runs 82 credits flat for a 5-second 720p clip with no built-in audio. Vidu Q3's 5-second 720p clip is 40 credits and includes generated audio — cheaper at the short end, with Q3 reaching further in duration (up to 16s) but Seedance 2 reaching further in resolution (up to 4K).
Vidu Q3 vs Kling 3.0 — which is cheaper?
Kling 3.0's std tier with sound is about 8 credits/second (40 credits for 5 seconds), close to Vidu Q3's flat 40-credit 5-second 720p price. At longer durations Q3's flat-rate table (125-145 credits at 16s) becomes the more predictable option versus Kling 3.0's continued per-second billing.
What input and output options does Q3 support?
Text prompts or reference images in, 720p or 1080p out, framed at 16:9, 9:16, or 1:1 — covering widescreen, vertical, and square deliverables from one model.
Is Vidu open source?
No — Shengshu's Vidu line, including Q3, is a proprietary hosted API model with no open-weights release.
Vidu Q3 vs Q3 Turbo — which should I use?
They share the identical duration, resolution, aspect-ratio, and audio spec. Q3 Turbo costs roughly half as much at every combination and generates faster, at some cost to rendering quality — draft on Turbo, finish on standard Q3.
