Video to video

Changed on

Creates a project from a video and restyles it from a text prompt. The output keeps the restyled part's length and timing. Pass an uploaded video as videoFileId, or a public link as videoUrl and the run imports it for you. Up to 120 seconds of the video is restyled per run: choose the part with trimStartSeconds and trimEndSeconds, or omit them to restyle the first 120 seconds. Returns immediately with a workflow run id; poll or subscribe to webhooks for completion.

Request body

videoFileIdstring

Id of the video to restyle (e.g. vg_file_...), uploaded via POST /v1/files/upload. Provide exactly one of videoFileId or videoUrl.

videoUrlstring

Public http:// or https:// link to a video page or a video file to restyle. The run imports it before restyling, so you do not need to import it first. Private, login-only, and DRM-protected videos cannot be imported, and an unusable link fails the run. Provide exactly one of videoFileId or videoUrl.

trimStartSecondsnumber

Second of the video where the restyled part starts. Optional; defaults to 0. Must leave at least 2 seconds before the end of the video.

trimEndSecondsnumber

Second of the video where the restyled part ends. Optional; defaults to trimStartSeconds plus 120, capped at the end of the video. The restyled part must be between 2 and 120 seconds long.

promptstring required

Text prompt describing how the restyled video should look (e.g. Hand-made claymation with soft studio lighting). Must be non-empty.

imageFileIdsstring[]

Optional ids of up to 10 previously uploaded reference images (e.g. vg_file_...) that guide the look of the restyle.

quality'LOW' | 'STANDARD' | 'HIGH' | 'MAX'

Restyle quality (LOW, STANDARD, HIGH, or MAX). Higher tiers cost more and follow the source more faithfully. Optional; defaults to HIGH.

audio'KEEP_ORIGINAL' | 'GENERATE'

KEEP_ORIGINAL keeps the source video's audio under the restyled picture. GENERATE uses newly generated audio instead. Optional; defaults to KEEP_ORIGINAL.

isOutputTemporaryboolean

When true, the generated OUTPUT files (the restyled video clips) are created as temporary: guaranteed available for 24 hours, after which they may be archived and later deleted. Use this when your integration downloads or re-hosts the results itself and does not need VideoGen to retain them. The project and its metadata are unaffected. Defaults to false.

autoExportboolean

When true, VideoGen exports an MP4 after the video is built (and after any remixActions on this request finish). The workflow run stays running until that export succeeds or fails. On success, poll GET /v1/workflows/runs/{workflowRunId} and use downloadUrl. Defaults to false.

Response

Workflow run accepted.

workflowRunIdstring required

Opaque workflow run id (e.g. vg_work_...).

projectIdstring required

Id of the project created for this workflow run (e.g. vg_proj_...).

projectUrlstring uri required

Deep link to open this project in the VideoGen web editor. Not required for an API-only integration: store projectId and use the Projects API (export, remix, metadata). Use projectUrl when a person should open the project in the app to review or edit it manually. The project is visible only to members of your team and any project collaborators, the same access model as a project created in the dashboard.

remixActionIdsstring[] required

Opaque remix action ids (e.g. vg_rmix_...), one per remixActions entry in request order. Empty when no remix actions were requested. Each runs after the video is built; poll GET /v1/projects/{projectId}/remix-actions.
