ComfyUI Extension: ZZX Nodes

ZZX Nodes Introduction

ComfyUI-ZZXYWQ is an extension designed to enhance the capabilities of AI artists by providing advanced tools for digital painting and video processing. This extension includes several nodes that allow you to undo drawing actions, record streaming media, and convert video formats. By integrating these functionalities, ComfyUI-ZZXYWQ aims to streamline the creative process, making it easier for artists to experiment and refine their work without losing progress or quality.

How ZZX Nodes Works

ComfyUI-ZZXYWQ operates through a series of nodes, each designed to perform specific tasks. These nodes can be thought of as individual tools in a digital artist's toolkit. For example, the ZZX_PaintsUndo node allows you to undo specific parts of your line drawings, much like pressing the "undo" button in traditional digital painting software. The StreamRecorder node enables you to record streaming media in various formats, while the VideoFormatConverter node helps you transcode videos into different formats and encodings. By connecting these nodes in a workflow, you can achieve complex tasks with ease.

ZZX Nodes Features

ZZX_PaintsUndo

The ZZX_PaintsUndo node is inspired by the Paints-Undo project, which aims to model human drawing behaviors. This node allows you to undo specific parts of your line drawings. If there is an issue with the undo process, the output will be set to black. This feature is particularly useful for artists who want to experiment with different drawing techniques without the fear of making irreversible changes.

• Undo Line Drawing: Allows you to undo specific parts of your line drawings.
• Error Handling: If there is an issue, the output will be set to black.
• Known Bug: Outputs three pictures at a time.

StreamRecorder

The StreamRecorder node is designed for recording streaming media. It supports a variety of streaming formats and allows you to save recordings in multiple file formats and encodings. This node is highly customizable, offering options to use local time, set recording duration, and choose whether to use CUDA for hardware acceleration.

• Supported Streaming Formats: RTMP, .m3u8.
• Output Formats: MP4, MOV, MKV, AVI.
• Encodings: AV1, H264, H265. - Customization Options: Local time usage, recording duration, CUDA acceleration.

VideoFormatConverter

The VideoFormatConverter node allows you to transcode videos into different formats and encodings. This node is highly flexible, offering options for frame rate, resolution, audio format, and frequency.

• Output Formats: MP4, MOV, MKV, AVI.
• Encodings: AV1, H264, H265.
• Frame Rates: 8, 15, 24, 25, 30, 50, 59, 60, 120.
• Audio Formats: MP3, AAC.
• Frequencies: 44100, 48000.

ZZX Nodes Models

ComfyUI-ZZXYWQ does not include different models but rather focuses on providing versatile nodes that can be used in various workflows. Each node is designed to perform a specific function, and by combining these nodes, you can achieve a wide range of tasks.
