🎬 Veo 3.1 Text to Video:
The Veo31TextToVideo node is a powerful tool designed to transform text prompts into dynamic 8-second videos using the Veo 3.1 framework. This node leverages advanced AI models to generate high-quality video content, complete with audio, from simple textual descriptions. It offers three distinct models to cater to different needs: a standard model for high-quality output, a fast model for quicker results with slightly reduced quality, and a lite model for cost-effective and lightweight processing. The node supports various resolutions, including 720p, 1080p, and 4K, and allows for different aspect ratios such as 16:9 and 9:16, making it versatile for various creative projects. The fixed duration of 8 seconds ensures consistency across all outputs, aligning with the constraints of the Veo 3.1 system. This node is ideal for AI artists looking to quickly and efficiently generate video content from textual ideas, providing a seamless integration into creative workflows.
🎬 Veo 3.1 Text to Video Input Parameters:
text_prompt
The text prompt is the core input for the Veo31TextToVideo node, serving as the basis for the video generation process. It should be a descriptive sentence or phrase that encapsulates the visual and thematic elements you wish to see in the resulting video. The quality and relevance of the generated video are directly influenced by the clarity and detail of the text prompt. There are no strict minimum or maximum length requirements, but more detailed prompts can lead to richer video content.
model_type
This parameter allows you to select the model variant to be used for video generation. Options include veo3.1-text-to-video for standard quality, veo3.1-fast-text-to-video for faster processing with slightly lower quality, and veo3.1-lite-text-to-video for a lightweight and cost-effective option. The choice of model affects the processing time and quality of the output, with the standard model providing the best quality and the lite model being the most resource-efficient.
resolution
The resolution parameter determines the video quality and size, with options including 720p, 1080p, and 4K. Higher resolutions result in clearer and more detailed videos but may require more processing power and time. The choice of resolution should align with the intended use of the video, whether for online sharing, professional presentations, or other purposes.
aspect_ratio
This parameter specifies the aspect ratio of the video, with options of 16:9 for a widescreen format and 9:16 for a vertical format. The aspect ratio should be chosen based on the platform or medium where the video will be displayed, ensuring optimal viewing experience.
🎬 Veo 3.1 Text to Video Output Parameters:
video_url
The video_url is a string that provides the CDN URL of the generated MP4 video. This URL can be used to access, download, or share the video content created by the node. It is a crucial output as it links directly to the final product of the text-to-video conversion process.
first_frame
The first_frame is an image tensor representing the first frame of the generated video. This output is useful for previewing the video content within the ComfyUI interface, allowing you to quickly assess the initial visual quality and thematic alignment with the text prompt.
request_id
The request_id is a string that serves as a unique identifier for the original video generation request. It is essential for tracking and managing video generation tasks, especially when using additional nodes like Veo31ExtendVideo or Veo314KUpscale to further process or enhance the video.
🎬 Veo 3.1 Text to Video Usage Tips:
- Use detailed and specific text prompts to achieve more accurate and visually appealing video outputs.
- Choose the model type based on your priorities: standard for quality, fast for speed, and lite for cost-efficiency.
- Select the resolution and aspect ratio that best fit the intended platform or audience for your video.
