Input Schema
Section titled “Input Schema”| Field | Type | Default | Description |
|---|---|---|---|
formats | any[] | — | |
media_path | object | — | |
output_dir | string | "output/resized" | |
output_path | object | — | |
regenerate | object | — | When set, this run is a regeneration. Workflows may read direction / keep / extra_instructions to modulate prompts; the engine persists parent_run_id and parent_variant_index as run lineage columns. |
strategy | string | "pad" | |
variants | integer | 1 | Number of independent variant executions (1–10). When > 1, the engine runs the workflow N times with different sampling, producing N outputs. |
Output Schema
Section titled “Output Schema”No schema defined.
Task Pipeline
Section titled “Task Pipeline”resize_video| Task | Description |

resize_video | Resize a video to multiple target aspect ratios. |

input: {}Run it locally:
fab-workflow --from-file my-run.yamlOr submit over the wire — the same file is the request body:
curl -X POST 'https://gofabric.dev/v1/workflows/runs?name=media/resize' \ -H 'Authorization: Bearer fab_xxx' \ -H 'content-type: application/yaml' \ --data-binary @my-run.yamlEvery workflow also accepts the universal WorkflowInput fields — variants (1–10 fan-out) and regenerate (creative-direction hints with run lineage). See Run-specs (YAML / TOML / JSON) for the full top-level shape (metadata, priority, bundle, parent, etc.).
