Mischief 1 inputs
The JSON body of the request. Media inputs are URLs: upload a local file with POST /v2/files and pass the URL it returns. Full JSON Schema, no key needed: api.varg.ai/v2/tools/video?model=mischief_1
| Field | What it does |
|---|---|
model string required | mischief_1 picks a route automatically. |
prompt string | — |
files array of { url } | — |
aspect_ratio string | Allowed e.g. 16:9 | 9:16 | 1:1 | 4:3 | 3:4 | 21:9 | auto |
resolution string | Quality tier. Supported by this model: 480p, 720p. Unsupported tiers fall back to the nearest available. Allowed 480p | 720p | 1080p | 4k |
audio boolean | Native audio track request. Not supported by this model — ignored if sent. |
duration integer | Length in seconds. Supported by this model's routes: fal: 3, 5. A non-numeric value such as "auto" is routed to a route whose schema accepts it; when none does, the request is rejected. Allowed 1–120 |
Provider options
Optional, under provider_options.<provider>. Only the options of the provider that runs the job apply; pin a route to choose it.
provider_options.fal
| Field | What it does |
|---|---|
prompt string | What happens in the video. Long, specific prompts steer WAN best. |
seed integer | Allowed 0–2147483647 |
duration number | — |
image_url string (URL) | http(s) URL of the condition image the video starts from, at most 25 MiB and 100 megapixels. A JPEG or PNG within the endpoint's byte budget (2.5 MB by default) renders as sent; anything larger, and any other format, is re-encoded to fit (a JPEG stays JPEG, anything else becomes lossless PNG), scaled down only as far as needed and never below the requested resolution; where that resolution stops the shrink, it is sent as a JPEG of slightly lower quality instead. |
resolution string | Allowed 480p | 720p |
image_transform string | Allowed center_crop | resize |
prompt_processing string | Allowed original | enhanced |
