Submit the request with `VIDGO_API_KEY`. A `task_id` is returned immediately. Keep it until the task reaches `finished` or `failed`. 2. Use [Query Task Status](/api-manual/task-management/status) to retrieve the result. If you provide a `callback_url`, Vidgo sends the result to your [webhook](/api-manual/task-management/webhooks) when the task finishes or fails. # Omni Flash Video Edit Rework existing video with Gemini Omni Flash, using written instructions to guide changes to the scene with output up to 4K. ## Available Models * **google/gemini-omni-flash/video-edit** - Edit an existing video using written instructions. ## Duration Options * Provide one source video in `video_urls`. This workflow does not impose a source-video duration limit. * Do not send `duration` for video editing. ## Key Features * Edit an existing video using written instructions. * Choose from `720p`, `1080p`, `4k` output resolutions. * Supports landscape (`16:9`) and portrait (`9:16`) framing. ## Advanced Parameters Set `model` and optional `callback_url` at the request root. Place the parameters below inside `input`. Send only the input fields supported by this workflow. Unsupported `input` fields are rejected before credits are deducted. Input URLs must use HTTP(S), include a hostname, and contain no embedded credentials. ### Prompt * `prompt`: Required. Describe the requested changes to the video. * The prompt must not be blank when supplied. Maximum length: **20,000 characters**. ### Source Video * `video_urls`: Required. Provide an array containing exactly one publicly accessible source video URL. ### Resolution * `resolution`: `720p`, `1080p`, `4k`. Default: `720p`. ### Aspect Ratio * `aspect_ratio`: `16:9`, `9:16`. Default: `16:9`. ## Pricing Pricing depends on the selected model and applicable output settings. Check the Vidgo dashboard for the current rate. Credits are deducted on submission and refunded if the task fails. ## OpenAPI ````yaml api-manual/video-series/google-gemini-omni-flash-video-edit.json POST /api/generate/submit openapi: 3.0.0 info: title: Vidgo API - Omni Flash Video Edit description: >- Rework existing video with Gemini Omni Flash, using written instructions to guide changes to the scene with output up to 4K. version: 1.0.0 servers: - url: https://api.vidgo.ai security: - BearerAuth: [] paths: /api/generate/submit: post: tags: - Video Series summary: Omni Flash Video Edit description: >- Send only the fields shown for this workflow.
