An animated GIF input converts to any video target (gif→mp4). **Synchronous** — the converted file's download URL is in the response. **Pricing: 10 credits per conversion**, charged only on success. Estimate via [`POST /v1/cost`](/api-reference/models/estimate-the-cost-of-a-request) with `{"model": "convert-video"}`. `file` accepts a public URL (up to 30 MB), an uploaded-file URL from [`POST /v1/uploads`](/api-reference/files/upload-input-media) (up to 50 MB), a data URI, or raw base64. **Videos must be 30 seconds or shorter.** Results are stored privately and deleted after 7 days. ## OpenAPI ````yaml /openapi.yaml post /convert/video openapi: 3.1.0 info: contact: email: support@budgetpixel.com name: BudgetPixel Support description: > The BudgetPixel developer API for programmatic image and video generation. Generation is **asynchronous**: you create a job, then poll its status until it reaches a terminal state (`succeeded` / `failed`). You are charged in credits only on success — never for failures, timeouts, or content blocked before generation. **Authentication.** All requests require an API key sent as a bearer token: Authorization: Bearer bpx_live_xxx Create and manage keys from your BudgetPixel account dashboard. The developer API is currently available on the **Ultra** plan. **Pricing.** API usage is metered in credits at each model's published price (see `GET /v1/models`). Consumer subscription perks (free daily generations, free-for-Ultra models, subscription discounts) do not apply to API traffic. title: BudgetPixel API version: '2026-06-20' servers: - description: Production url: https://api.budgetpixel.com/v1 security: - ApiKeyAuth: [] tags: - description: Account and credit balance name: Account - description: Discover available models and pricing name: Models - description: Upload input media for image/video generation name: Uploads - description: Image job status name: Images - description: FLUX image models name: Black Forest Labs - description: SeeDream image models name: Bytedance - description: Video job status name: Videos - description: Kuaishou Kling video models name: Kling - description: SeeDance video models name: ByteDance (SeeDance) - description: Music job status name: Audios - description: Music generation models name: Music - description: Format conversion for images, video, and audio name: Conversions - description: Publish posts to your BudgetPixel feed name: Social - description: Content moderation — NSFW rating and CSAM detection name: Moderation - description: Content classification — music genre detection name: Classification paths: /convert/video: post: tags: - Conversions summary: Convert a video description: > Convert a video to `mp4`, `webm`, `mov`, or `gif` (video→gif is palette-optimized).
