ShengShu Vidu Q3 video generation series. Reference-to-video (R2V) is the flagship capability — accepts 1-7 public images as subject / style references, with the prompt focused on motion and camera while the appearance comes from the reference images. Best fit for character consistency / style continuity / multi-shot transitions. Four tiers:

viduq3-pro — flagship tier, auto-routes T2V / I2V / first-last frame by image_urls count, audio output enabled by default (dialog + SFX)
viduq3-mix — overall quality king, supports multi-clip video / image remix for coherent video output, joint audio generation, 720P / 1080P, ideal for short-drama re-cutting and ad creative remix
viduq3 — standard tier, the default daily choice, smarter shot transitions, 540p / 720p / 1080p, 3-16 sec
viduq3-turbo — lightweight fast tier, fastest generation and lowest unit price, slightly lower quality than standard, ideal for previews / batch / A/B testing

Billed by resolution × duration, per-second pricing, any integer 1-16 sec.

Common Parameters

string

required

Model ID; see the Available Models table

string

Operation type. Pro tier may be omitted (auto-routed by image_urls count); other tiers should specify it explicitly. Allowed values:

generate — text-to-video (Pro only)
image2video — image-to-video
reference — reference-to-video (default for standard / Mix / Turbo)
first_last_frame — first/last frame (Pro only)

string

required

Video description text. Focus on motion / camera / atmosphere — character appearance is determined by image_urls

string

default:"16:9"

Frame aspect ratio. Allowed values:

16:9 — landscape widescreen
9:16 — portrait
4:3 — landscape
3:4 — portrait
1:1 — square

string

default:"720p"

Output resolution; see Available Models for per-model support

integer

default:"5"

Video duration in seconds, any integer 1-16. Mix tier supports 1-second short videos

string[]

Reference image URL array, 1-7 images:

Standard / Mix / Turbo: subject / style references (R2V)
Pro tier: 0 = T2V / 1 = I2V / 2 = first-last frame; see Auto-routing

string

First-frame image URL, required for Pro first_last_frame mode

string

Last-frame image URL, required for Pro first_last_frame mode

string

Webhook callback URL, invoked when the task reaches a terminal state. See Callback Mechanism

string[]

Subscribed callback events; defaults to terminal events (succeeded / failed / cancelled)

Model-specific Parameters

viduq3-pro
viduq3-mix
viduq3
viduq3-turbo

boolean

default:"true"

Whether to generate audio (default true). Pro tier enables audio output by default (dialog + SFX); set false for silent output

Pro tier auto-routes the generation mode by image_urls count; see Auto-routing.

Mix tier has no specific parameters. Note that resolution only supports 720P / 1080P, 540P is not supported.Mix tier enables multi-asset joint generation by default — pass multiple references via image_urls (1-7) and the system applies smart transitions, ideal for short-drama re-cutting and ad creative remix.

Auto-routing

viduq3-pro auto-selects the generation mode by image_urls array length, so you usually don’t need to pass action explicitly:

`image_urls` count	Routed mode	Equivalent `action`	Notes
`0` (or omitted)	Text-to-video	`generate`	Pure prompt-driven
`1`	Image-to-video	`image2video`	The image serves as the starting frame
`2`	First-last frame	`first_last_frame`	First image = first frame, second image = last frame

When first_frame_image + last_frame_image are passed explicitly, they take precedence and override the first-last-frame routing from image_urls.

Other tiers (viduq3 / viduq3-mix / viduq3-turbo) default to R2V reference-to-video mode, with image_urls providing 1-7 subject / style references.

Resource Limits

Item	Limit
Reference images	Up to 7, each ≤ 30MB, JPG / PNG / WEBP
First/last-frame images	JPG / PNG / WEBP, public download URL required
Prompt length	≤ 2000 characters recommended
Video duration	Any integer 1-16 sec (Mix supports 1-second short videos)
Output	MP4, link valid for 24 hours
