grok-imagine の完全ガイド
Use ApiPass to convert still images into short animated videos with coherent motion, depth, lighting variation, and optional synchronized audio. The endpoint is asynchronous and is designed for creative apps, product previews, character animation, and automated visual workflows.
ApiPass supports two mutually exclusive input sources for grok-imagine/image-to-video: external image URLs or a previous text-to-image task ID.
Transform a still image into a smooth short video while preserving the original composition and visual identity.
Choose fun for playful results, normal for balanced motion, or spicy for more dynamic and intense animation. Spicy mode is only supported when using task_id, not external image_urls.
Generate videos from 6 to 30 seconds at 480p or 720p.
Use 2:3, 3:2, 1:1, 16:9, or 9:16. In single-image mode, output dimensions follow the input image aspect ratio.
Use callBackUrl for completion notifications or query /api/v1/jobs/recordInfo with the returned taskId.
Add a slow push-in, subtle parallax, atmospheric motion, and natural lighting shifts to a reference image.
Generate short visual clips that combine motion with audio cues for a more complete video output.
Experiment with mode settings to produce balanced, playful, or more intense movement.
Turn concept art, product images, or design references into short clips for quick review and iteration.
Create an asynchronous generation task, then receive the result through a callback or poll the task record.
Use image_urls for external reference images, or use task_id with index for a previous grok-imagine/text-to-image task. These two input sources must not be sent together.
Add a prompt that explains the desired action, camera movement, scene dynamics, rhythm, and lighting. Clear prompts usually produce more controllable motion.
Choose mode, duration, resolution, and aspect_ratio. Use normal mode with external image_urls; spicy mode is not supported for external image input.
Send a POST request to /api/v1/jobs/createTask. ApiPass returns a taskId and status. Use callBackUrl for production completion notifications or query /api/v1/jobs/recordInfo as a fallback.
The grok-imagine/image-to-video endpoint uses ApiPass asynchronous job creation and task querying.
POST https://api.apipass.dev/api/v1/jobs/createTask with Authorization: Bearer YOUR_API_KEY. The request body should include model: grok-imagine/image-to-video, optional channel, optional callBackUrl, and an input object.
GET https://api.apipass.dev/api/v1/jobs/recordInfo?taskId=YOUR_TASK_ID with Authorization: Bearer YOUR_API_KEY. Use the taskId returned by createTask.
If callBackUrl is provided, ApiPass sends task updates when the asynchronous task succeeds or fails. Polling recordInfo can be used as a fallback.
Provide exactly one input source: image_urls or task_id. image_urls supports up to 7 JPEG, PNG, or WEBP images, each 10MB or smaller. task_id can be up to 100 characters. index must be 0 through 5. duration must be a string value from 6 to 30.
Create short, shareable motion clips from a product image, concept frame, character design, or visual prompt.
Embed image-to-video generation into creative tools, campaign builders, onboarding flows, preview systems, and dynamic content experiences.
Animate static product images or design mockups with camera movement, depth, and lighting changes for fast stakeholder review.
Test different motion styles and prompt variations to discover visual directions before committing to full production.

Create an asynchronous image-to-video task with grok-imagine/image-to-video. Provide either external reference image URLs or a previous Grok text-to-image task_id plus index, then describe the desired motion with an optional prompt.

grok-imagine/image-to-video
channelオプションstringDefault channel is auto. APIPASS automatically allocates tasks across available providers based on real-time pricing and stability metrics; starter is ultra-low-cost with limited quotas and weaker stability; regular is standard and much cheaper than official APIs with moderate stability; official uses the model native API with high stability, fast task execution, and official pricing.

利用可能なオプション：
auto
callBackUrlオプションstringCallback URL that ApiPass will call when the task finishes or fails. Recommended for production workflows so you do not need to rely only on polling.
https://your-domain.com/api/callback
image_urlsオプションarray<string>External reference image URLs for video generation. Use this field when you want to animate uploaded or externally hosted images. Do not provide task_id at the same time.
Provide either image_urls or task_id. image_urls supports up to 7 images, each image must be 10MB or smaller, and supported formats are JPEG, PNG, and WEBP. You can reference images in the prompt with @image1, @image2, and so on. External image mode does not support spicy mode.
[ "https://cdn.apipass.dev/apipass/results/task_78514b0d12c44ad4_0.png" ]
task_idオプションstringTask ID from a previous grok-imagine/text-to-image generation. Use it together with index to select one Grok-generated image. Do not provide image_urls at the same time.
Provide either task_id or image_urls. task_id can be up to 100 characters. This mode supports all mode values, including spicy.
task_grok_12345678
indexオプションintegerSelects which image to use from the previous Grok image task when task_id is provided. Grok generates 6 images per task, so valid values are 0 through 5.
Default is 0. This parameter is only used with task_id and is ignored when image_urls is provided.
0
promptオプションstringText prompt describing the desired video motion.
Although optional, a clear prompt is recommended. Describe the action, camera movement, rhythm, subject, environment, and motion dynamics. English prompts are supported. Maximum length is 5000 characters.
Make the scene come alive with a slow cinematic camera push-in and subtle atmospheric motion.
modeオプションstringControls the motion style and intensity.
Default is normal. fun is more creative and playful, normal is balanced, and spicy is more dynamic and intense. When using external image_urls, spicy mode is not supported and should not be used.
利用可能なオプション：
normal
durationオプションstringDuration of the generated video in seconds. The schema type is string, but the value should be an integer number of seconds from 6 to 30.
Valid values are integer seconds from 6 to 30, with a step of 1.
6
resolutionオプションstringResolution of the generated video.
Default is 480p.
利用可能なオプション：
480p
aspect_ratioオプションstringAspect ratio of the generated video.
Default is 16:9. This parameter applies to multi-image generation mode. In single-image mode, the video dimensions follow the input image aspect ratio.
利用可能なオプション：
16:9
