VIDU Q2 Pro Fast start-end frame to video API, supports 720p and 1080p resolutions. Fast mode significantly reduces generation time.

This is an asynchronous API; only the task_id will be returned. You should use the task_id to request the [Task Result API](/docs/api-reference/model-apis-task-result) to retrieve the video generation results.

Random seed. Default or 0 uses random number. Manual setting uses specified seed.

[​](#param-images)

images

string[]

required

Images array, first image is start frame, second image is end frame. Supports two images. Note: 1) Resolution ratio of start/end frames should be between 0.8-1.25; 2) Supports Base64 encoding or image URL; 3) Supports png, jpeg, jpg, webp formats; 4) Max size 50M per image; 5) Base64 must include proper content type, e.g., data:image/png;base64,Array length: 2 - 2

[​](#param-is-rec)

is_rec

boolean

default:false

Whether to use recommended prompt. true: system automatically recommends and uses prompt (consumes 10 extra credits); false: use input prompt

[​](#param-prompt)

prompt

string

Text prompt describing the desired video content. Max 2000 characters. Note: If is_rec is enabled, this parameter will be ignoredLength limit: 0 - 2000

[​](#param-wm-url)

wm_url

string

Watermark content image URL. If not provided, uses default watermark: ‘Generated by AI’

[​](#param-payload)

payload

string

Pass-through parameter, no processing, data transmission only. Max 1048576 characters.Length limit: 0 - 1048576

[​](#param-duration)

duration

integer

default:5

Video duration in seconds, supports 1-8 secondsOptional values: `1`, `2`, `3`, `4`, `5`, `6`, `7`, `8`

[​](#param-off-peak)

off_peak

boolean

default:false

Off-peak mode. true: off-peak generation (lower credits, completed within 48 hours); false: immediate generation. Note: Off-peak tasks can be manually cancelled and credits refunded if not completed.

[​](#param-meta-data)

meta_data

string

Metadata identifier in JSON string format. Pass-through field. You can define custom format or use example format. When empty, uses Vidu-generated metadata.
