--- title: P-Video-Replace | Runware Docs url: https://runware.ai/docs/models/prunaai-p-video-replace description: Character replacement for existing video using a reference image while preserving motion, timing, camera, and scene --- # P-Video-Replace P-Video-Replace is a video transformation model that swaps the on-camera character in an existing video with the character from a reference image. It is built to preserve the original motion, timing, camera behavior, lighting, and background while changing who appears in the clip, making it useful for UGC ad variations, content localization, avatar or mascot insertion, and other scalable character-replacement workflows. - **ID**: `prunaai:p-video@replace` - **Status**: live - **Creator**: Pruna AI - **Release Date**: June 4, 2026 - **Capabilities**: Image to Video, Video to Video, Edit, Checkpoint ## Pricing Pricing starts at $0.03 per second of output at 720p and $0.06 at 1080p - **720p . 1s**: `$0.03` - **1080p . 1s**: `$0.06` ## Compatibility & Validation When `resolution` is provided, `inputs.referenceImages` or `inputs.video` is required. ## Request Parameters **API Options** Platform-level options for task execution and delivery. ### [taskType](https://runware.ai/docs/models/prunaai-p-video-replace#request-tasktype) - **Type**: `string` - **Required**: true - **Value**: `videoInference` Identifier for the type of task being performed ### [taskUUID](https://runware.ai/docs/models/prunaai-p-video-replace#request-taskuuid) - **Type**: `string` - **Required**: true - **Format**: `UUID v4` UUID v4 identifier for tracking tasks and matching async responses.
