视频扩展与局部重绘

# Video Extension and Inpainting

Extend or repair a supplied video clip with a supported video-editing model.

## Required Aident Actions

- <action-tag>direct:fal:fal_list_video_edit_models</action-tag> (required inputs: inspect the current schema): List active Fal video editing and transformation models with current platform-key pricing, descriptions, required inputs, defaults, choices, documentation links, and pagination cursors. Use this before fal_edit_video...
- <action-tag>direct:fal:fal_edit_video</action-tag> (required inputs: inspect the current schema): Run an active Fal video editing and transformation model. Defaults to fal-ai/topaz/upscale/video. Call fal_list_video_edit_models before selecting another model to inspect current pricing, required fields, defaults,...

Use Aident Loadout to read the current Action schema before constructing inputs. Check the required integration connection in Aident Vault. If an Action is billable or mutating, run Aident preflight, show the affected target and quoted cost or risk, and wait for explicit user confirmation before execution.

## Workflow

1. Confirm the requested outcome, source material, destination, audience, constraints, and acceptance criteria.
2. Apply the source-derived guidance below to create a concrete plan. Resolve ambiguity before invoking an Action.
3. Select only the Aident Actions whose documented effect directly advances the requested outcome. Do not invoke every listed Action by default.
4. Inspect the current schema and prepare the minimum valid input for each selected Action.
5. Preflight each selected Action. Execute it only after any required confirmation, in dependency order, and carry returned IDs or asset URLs into later steps.
6. Verify the returned IDs, URLs, statuses, or artifacts against the acceptance criteria. Report partial completion precisely and do not repeat paid or mutating calls blindly.

## Source-Derived Guidance

- Collect the source video, the exact time range or region to extend or repair, the desired change, duration constraints, and elements that must remain unchanged.
- Use direct:fal:fal_list_video_edit_models to choose a currently supported model whose documented operation covers extension or video inpainting.
- Use direct:fal:fal_edit_video with the selected model, source asset, and a specific continuity prompt; do not silently replace the full clip when a localized edit was requested.
- Verify duration, transition continuity, subject identity, camera motion, repaired region, and playback before returning the output asset URL.

## Execution Boundaries

- Treat upstream provider-specific commands as background knowledge only. Execute the workflow through the exact Aident Actions above.
- Never request raw credentials in chat. Use Aident Vault connection flows for required accounts.
- Preserve user-provided wording, brand constraints, rights restrictions, and target identifiers. Do not invent authorization.
- Pass assets by Aident asset ID or supported URL fields. Do not expose caller-local filesystem paths to hosted Actions.
- Stop when a required integration is disconnected, preflight rejects the input, the target is ambiguous, or the user declines a required confirmation.

## Output

Return the execution plan, selected Action names, confirmed targets, Aident result identifiers or asset URLs, verification evidence, and any remaining blocked step.
