ComfyUI Node: Blend Video Combine

Blend Video Combine:

The BlendVideoCombine node is designed to seamlessly merge image frames into animated formats such as GIF or WebP, providing a dynamic and visually engaging output. This node is particularly beneficial for creating smooth transitions between video clips, allowing for both full video combinations and transition-only modes. By leveraging the VideoHelperSuite's VideoCombine node pattern, it ensures efficient processing and high-quality results. The node supports preview functionality, enabling you to visualize the animation before finalizing the output. This capability is especially useful for AI artists looking to create captivating animations with minimal effort, as it simplifies the process of blending video clips while offering customization options to suit various artistic needs.

Blend Video Combine Input Parameters:

images

This parameter accepts a sequence of images that will be combined into an animated format. The images serve as the frames of the animation, and their order determines the sequence of the animation.

frame_rate

The frame rate determines how many frames are displayed per second in the resulting animation. It can range from 1.0 to 120.0, with a default value of 30.0. A higher frame rate results in smoother animations, while a lower frame rate can create a more choppy effect.

filename_prefix

This string parameter sets the prefix for the output file's name. By default, it is set to "BlendPack". This helps in organizing and identifying the output files, especially when generating multiple animations.

format

This parameter allows you to choose the output format of the animation, with options including "webp" and "gif". Each format has its own advantages, such as file size and quality, and the choice depends on the intended use of the animation.

save_output

A boolean parameter that determines whether the output animation should be saved to disk. By default, it is set to True, ensuring that the generated animation is stored for future use.

loop_count

This integer parameter specifies how many times the animation should loop. It ranges from 0 to 100, with a default value of 0, which typically means the animation will loop indefinitely.

blend_info

An optional string parameter that can be used to provide additional information about the blending process. It supports multiline input, allowing for detailed descriptions or notes.

Blend Video Combine Output Parameters:

(No output parameters)

The BlendVideoCombine node does not explicitly return any output parameters. Instead, it focuses on generating and saving the animated output based on the provided input parameters.

Blend Video Combine Usage Tips:

• To achieve smoother animations, consider increasing the frame_rate parameter, but be mindful of the potential increase in file size and processing time.
• Utilize the blend_info parameter to document specific blending techniques or settings used, which can be helpful for future reference or when sharing your work with others.

Blend Video Combine Common Errors and Solutions:

Failed to load video frames

• Explanation: This error occurs when the node is unable to read the video frames from the specified path, possibly due to an incorrect file path or unsupported video format.
• Solution: Ensure that the video file path is correct and that the file is in a supported format. Additionally, check if the file is accessible and not corrupted.

Invalid frame rate value

• Explanation: This error arises when the frame_rate parameter is set outside the allowed range of 1.0 to 120.0.
• Solution: Adjust the frame_rate parameter to fall within the specified range to ensure proper animation playback.

Unsupported output format

• Explanation: This error is triggered when an unsupported format is selected for the format parameter.
• Solution: Choose either "webp" or "gif" as the output format to ensure compatibility with the node's capabilities.
