SuperUltimate VACE Long Video Input Parameters:

model

The model parameter specifies the VACE model to be used for video generation. It is crucial as it determines the underlying algorithm and capabilities available for processing the video content. Only VACE models are supported, ensuring compatibility and optimal performance.

clip

The clip parameter refers to the CLIP model used for encoding text. This model plays a vital role in understanding and processing textual prompts that guide the video generation process. It ensures that the generated video aligns with the provided textual descriptions.

vae

The vae parameter represents the Variational Autoencoder (VAE) used in the video generation process. The VAE is responsible for encoding and decoding video data, contributing to the quality and fidelity of the final output.

width

The width parameter defines the width of the generated video in pixels. It has a default value of 832, with a minimum of 16 and a maximum determined by the system's maximum resolution. This parameter impacts the video's aspect ratio and overall resolution.

height

The height parameter specifies the height of the generated video in pixels. Similar to the width, it has a default value of 832, with a minimum of 16 and a maximum determined by the system's maximum resolution. Adjusting this parameter affects the video's aspect ratio and resolution.

loopback_crossfade

The loopback_crossfade parameter controls the number of frames used for crossfading when looping back to the start of the video. It ranges from 0 to 10000, with a default value of 0. This parameter is essential for creating smooth transitions in looping videos.

vace_prompt_list

The vace_prompt_list parameter is a list of prompts that guide the video generation process. These prompts provide textual descriptions that influence the content and style of the generated video, allowing for creative control over the output.

seed

The seed parameter is an integer used to initialize the random number generator for video generation. It has a default value of 0 and can range from 0 to 0xffffffffffffffff. This parameter ensures reproducibility of results by controlling the randomness in the generation process.

steps

The steps parameter determines the number of steps used in the video generation process. It has a default value of 20, with a minimum of 1 and a maximum of 10000. This parameter affects the detail and quality of the generated video, with more steps generally leading to higher quality.

cfg

The cfg parameter, or configuration, is a floating-point value that influences the strength of the guidance during video generation. It has a default value of 8.0, with a range from 0.0 to 100.0. This parameter helps balance creativity and adherence to the prompts.

sampler_name

The sampler_name parameter specifies the sampler to be used in the video generation process. It is selected from a predefined list of samplers available in the KSampler module. The choice of sampler can affect the style and characteristics of the generated video.

scheduler

The scheduler parameter determines the scheduling strategy used during video generation. It is selected from a predefined list of schedulers available in the KSampler module. The scheduler influences the timing and sequence of operations in the generation process.

denoise

The denoise parameter is a floating-point value that controls the level of noise reduction applied during video generation. It has a default value of 1.0, with a range from 0.0 to 1.0. This parameter helps improve the clarity and quality of the final video output.

vace_control_list (optional)

The vace_control_list parameter is an optional list of control images used to guide the video generation process. These images provide additional reference points for the model, allowing for more precise control over the video's content and style.

nag_params (optional)

The nag_params parameter is an optional setting for NAG (Neural Artistic Guidance) parameters. These settings provide additional control over the artistic style and characteristics of the generated video, allowing for further customization and creativity.

SuperUltimate VACE Long Video Output Parameters:

IMAGE

The IMAGE output parameter represents the generated video as a sequence of images. This output is the final result of the video generation process, encapsulating the combined effects of all input parameters and settings. The generated video can be used for various creative and artistic purposes, providing a visual representation of the input prompts and configurations.

SuperUltimate VACE Long Video Usage Tips:

• To achieve smooth transitions between video segments, adjust the loopback_crossfade parameter to an appropriate value based on the desired effect.
• Experiment with different cfg values to find the right balance between creativity and adherence to the input prompts, enhancing the artistic quality of the video.
• Utilize the vace_prompt_list to provide detailed and specific prompts that guide the video generation process, ensuring the final output aligns with your creative vision.

SuperUltimate VACE Long Video Common Errors and Solutions:

identical frame_position detected, check the frame_position setting

• Explanation: This error occurs when two or more control frames have the same frame position, leading to conflicts in the video generation process.
• Solution: Review the vace_control_list and ensure that each control frame has a unique frame position to avoid overlaps.

some control frames overlapped, check the frame_position setting

• Explanation: This error indicates that the control frames overlap, causing issues in the video generation process.
• Solution: Adjust the vace_control_list to ensure that control frames do not overlap, maintaining distinct and separate frame positions.

Length of control image exceeds length of generation

• Explanation: This error occurs when the length of the control images specified in the vace_control_list exceeds the total length of the generated video.
• Solution: Ensure that the control images' length is within the bounds of the total video length, adjusting the vace_control_list as necessary.
