## Basic tool info Model name: blackforestlabs/flux-3-i2v Model description: FLUX 3 I2V turns 1–10 images and a prompt into a 5–20s MP4 clip at 720p or 1080p, with optional native audio and keyframe timing. Model cover: https://cdn.wiro.ai/uploads/models/blackforestlabs-flux-3-i2v-cover.mp4 Model categories: - tool - use-agent - nogpu-pipeline - text-to-video - image-to-video - partner - quick-showcase - hero-showcase Run Task Endpoint (POST): https://api.wiro.ai/v1/Run/blackforestlabs/flux-3-i2v Get Task Detail Endpoint (POST): https://api.wiro.ai/v1/Task/Detail ## Model Inputs: - name: inputImage label: Input Image help: Optional. Leave empty to generate from the prompt alone. One image opens the video, two set its first and last frames, and from three up the first opens it, the last ends it and the rest fall in between. Up to 10 images. type: combinefileinput default: flux-3-i2v-input-2.jpg - name: prompt label: Prompt help: Required. Describes the video to generate. Speech in quotes is spoken on camera. type: textarea default: Cinematic forward tracking shot down a bustling, overcast London street. In the foreground, the bright red double-decker bus slowly rolls forward, its headlights glaring slightly and the 'Edmonton Green 149' LED destination sign subtly flickering. Simultaneously, the black taxi on the left accelerates smoothly down the lane, moving toward the yellow truck in the midground. Pedestrians on the sidewalks walk briskly past the colorful, abstract wireframe sculpture on the right. Environmental details include subtle, moving reflections on the glass facade of the office building to the left, and thick morning mist slowly rolling past the iconic Gherkin skyscraper in the distant background. Photorealistic, urban documentary style. - name: imageFrame label: Image Frames (seconds) help: Optional. Only used with 3 or more images. Comma separated seconds for the images between the first and the last, in rising order, for example 4.5 for 3 images or 3,7 for 4 images. The first image always starts the video and the last always ends it, so 10 images take at most 8 timings. The images are spread evenly when left empty. type: text default: - name: duration label: Duration (seconds) help: Required. Length of the video in whole seconds, between 5 and 20. type: number default: 5 - name: aspectRatio label: Aspect Ratio help: Optional. Default auto, which picks the shape from the prompt and the images. type: select default: auto options: - value: "auto" label: auto - value: "21:9" label: 21:9 - value: "2:1" label: 2:1 - value: "16:9" label: 16:9 - value: "4:3" label: 4:3 - value: "1:1" label: 1:1 - value: "3:4" label: 3:4 - value: "9:16" label: 9:16 - name: resolution label: Resolution help: Required. Default hd. Choose fhd for a higher resolution result. type: select default: hd options: - value: "hd" label: hd - value: "fhd" label: fhd - name: generateAudio label: Generate Audio help: Optional. Default true. Creates sound together with the video. Set false for a silent clip. type: select default: true options: - value: "true" label: true - value: "false" label: false - name: safetyTolerance label: Safety Tolerance help: Optional. Default 4. How strict the content check is, 1 being the strictest and 4 the most permissive. Tolerance level for input and output harm moderation. Between 0 and 4, with 0 the strictest. Sexual content is limited to level 3 and hate content to level 2 regardless of the requested tolerance. Contextual safety signals can tighten the requested level. Requests with conditioning media are limited to level 2. type: number default: 4 ## Integration Header Prepare ```bash # Sign up Wiro dashboard and create project export YOUR_API_KEY="{{useSelectedProjectAPIKey}}"; export YOUR_API_SECRET="XXXXXXXXX"; # unix time or any random integer value export NONCE=$(date +%s); # hmac-SHA256 (YOUR_API_SECRET+Nonce) with YOUR_API_KEY export SIGNATURE="$(echo -n "${YOUR_API_SECRET}${NONCE}" | openssl dgst -sha256 -hmac "${YOUR_API_KEY}")"; ``` ## Run Command - Make HTTP Post Request ```bash curl -X POST "https://api.wiro.ai/v1/Run/blackforestlabs/flux-3-i2v" -H "Content-Type: multipart/form-data" -H "x-api-key: ${YOUR_API_KEY}" -H "x-nonce: ${NONCE}" -H "x-signature: ${SIGNATURE}" -d '{ "inputImage": "flux-3-i2v-input-2.jpg", "prompt": "Cinematic forward tracking shot down a bustling, overcast London street.

Once any of these is received, polling should stop. - task_postprocess_end : Task completed successfully and post-processing is done. - task_cancel : Task was cancelled by the user or system. ### Running Task Statuses (Continue polling) These statuses indicate that the task is still in progress. Polling should continue if one of these is returned. - task_queue : Task is waiting in the queue. - task_accept : Task has been accepted for processing. - task_assign : Task is being assigned to a worker. - task_preprocess_start : Preprocessing is starting. - task_preprocess_end : Preprocessing is complete. - task_start : Task execution has started. - task_output : Output is being generated.
