ComfyUI Node: 🎬 Veo 3.1 Extend Video

🎬 Veo 3.1 Extend Video:

Veo31ExtendVideo is a powerful tool designed to seamlessly extend video content generated by the Veo 3.1 suite. This node allows you to continue a video sequence by using a request_id from a previous Veo 3.1 generation, such as Text-to-Video (T2V), Image-to-Video (I2V), or Reference-to-Video (Ref2V). By providing a descriptive prompt of what should happen next in the video, you can create a smooth continuation of the narrative or visual style. This capability is particularly beneficial for creators looking to expand their video projects without starting from scratch, ensuring consistency and coherence in extended video content.

🎬 Veo 3.1 Extend Video Input Parameters:

api_key

The api_key is a string parameter required to authenticate your request with the Veo 3.1 API. It ensures that only authorized users can access and utilize the video extension capabilities. This parameter does not have a default value and must be provided for the node to function.

request_id

The request_id is a string parameter that serves as a reference to a previous video generation request within the Veo 3.1 framework. It is crucial for linking the new video extension to the original content, ensuring continuity. The default value is an empty string, and it should be replaced with the actual request_id from a prior Veo 3.1 generation.

prompt

The prompt is a string parameter that describes the desired continuation of the video. It allows for multiline input, enabling detailed descriptions of the scene, actions, or atmosphere you wish to create. The default prompt suggests continuing the scene with dramatic camera movement and ambient sound, but it can be customized to fit your specific creative vision.

extra_params_json

The extra_params_json is an optional string parameter that allows you to pass additional configuration settings in JSON format. This can be used to fine-tune the video extension process, although it defaults to an empty JSON object ({}) if not specified.

🎬 Veo 3.1 Extend Video Output Parameters:

video_url

The video_url is a string output that provides the CDN URL of the extended video. This URL can be used to access and download the newly generated video content, making it easy to share or integrate into other projects.

first_frame

The first_frame is an image output that offers a preview of the first frame of the extended video. This visual snapshot helps you quickly assess the initial appearance and style of the video extension.

new_request_id

The new_request_id is a string output that serves as a unique identifier for the current video extension request. It can be used for further chaining of video extensions, allowing for iterative development and refinement of your video projects.

🎬 Veo 3.1 Extend Video Usage Tips:

• Ensure that your api_key is valid and correctly entered to avoid authentication issues.
• Use a detailed and specific prompt to guide the video extension process effectively, ensuring that the continuation aligns with your creative goals.
• Consider using the extra_params_json to experiment with additional settings that might enhance the video extension results.
