ComfyUI Node: VideoBasic Video Upscale with Model

VideoBasic Video Upscale with Model:

The VideoBasicVideoUpscaleWithModel node is designed to enhance the resolution of video files using a specified upscaling model. This node is particularly beneficial for AI artists and video creators who wish to improve the visual quality of their videos by increasing their resolution. The node leverages advanced upscaling techniques to process video frames in batches, ensuring efficient handling of large video files. By utilizing a model that scales the video dimensions, it provides a seamless way to achieve higher resolution outputs, making it an essential tool for enhancing video clarity and detail. The node is capable of handling various video formats and ensures that the output is saved in a widely compatible format, such as MP4. Its primary goal is to provide a user-friendly interface for video upscaling, allowing users to focus on creative aspects without worrying about the technical complexities involved in video processing.

VideoBasic Video Upscale with Model Input Parameters:

upscale_model

The upscale_model parameter specifies the model used for upscaling the video. This model determines the scale factor by which the video resolution will be increased. The choice of model can significantly impact the quality of the upscaled video, as different models may have varying capabilities in terms of detail enhancement and artifact reduction. There are no specific minimum or maximum values for this parameter, but it is crucial to select a model that is compatible with the node and suitable for the desired output quality.

video_path

The video_path parameter is the file path to the video that you wish to upscale. It is essential that the path is correct and points to an existing video file, as the node will raise an error if the file is not found. This parameter does not have a default value, and it must be provided by the user to ensure the node can access and process the video.

batch_size

The batch_size parameter determines the number of video frames processed in each batch during the upscaling operation. A larger batch size can lead to faster processing times but may require more memory, while a smaller batch size can be more memory-efficient but slower. The choice of batch size should balance performance and resource availability, with no specific minimum or maximum values enforced by the node.

VideoBasic Video Upscale with Model Output Parameters:

output_path

The output_path parameter is the file path where the upscaled video will be saved. This path is automatically generated by the node and ensures that the output video is stored in a temporary directory with a filename that indicates it has been upscaled. The output is typically in MP4 format, making it easy to share and view across different platforms and devices.

VideoBasic Video Upscale with Model Usage Tips:

• Ensure that the video_path is correct and points to a valid video file to avoid errors during processing.
• Choose an upscale_model that is well-suited for your specific video content to achieve the best quality results.
• Adjust the batch_size according to your system's memory capacity to optimize processing speed and efficiency.

VideoBasic Video Upscale with Model Common Errors and Solutions:

Video file not found: <video_path>

• Explanation: This error occurs when the specified video file path does not exist or is incorrect.
• Solution: Verify that the video_path is correct and that the file exists at the specified location.

Could not open video file: <video_path>

• Explanation: This error indicates that the node was unable to open the video file, possibly due to file corruption or unsupported format.
• Solution: Check the video file for corruption and ensure it is in a supported format. Try opening the file with a standard video player to confirm its integrity.

Out of Memory (OOM) Exception

• Explanation: This error occurs when the node runs out of memory while processing video frames, often due to a large batch_size or high-resolution video.
• Solution: Reduce the batch_size or close other applications to free up memory. Consider using a machine with more RAM if the problem persists.
