ComfyUI Batch Process

A collection of nodes for batch processing texts, images, videos, and LoRAs in ComfyUI

---

Core Features

🔧 Text Processing

• txt_batch_loader - Load and filter text files by filename patterns and content
• text_modify_tool - Edit text content with search/replace operations on prefixes, suffixes, or whole text

🖼️ Image Processing

• image_batch_loader - Load images with filtering, subfolder search, index range selection, and list output options
• image_batch_saver - Save images with companion text files, frame accumulation, and customizable naming

🎬 Video Processing

• video_batch_saver - Save videos with customizable formats, codecs, and companion text files

🎨 LoRA Processing

• lora_batch_loader - Load and apply LoRAs with filtering and cycling modes

---

Key Features

• File-Based Filtering - All loaders support filename pattern matching and regex
• Training-Ready Outputs - Maintains image-text relationships for ML datasets
• LoRA Management - Batch apply LoRAs with customizable strength settings
• Flexible Modes - Single, incremental, and random loading options
• Memory-Efficient Frame Accumulation - Append frames to existing files across loop iterations
• Index Range Selection - Select specific frame ranges for loading and saving
• Multi-Format Support - Supports PNG, JPG, GIF, WebP, TIFF, BMP formats

Nodes Overview

LoRA Batch Loader

Loads LoRAs from a directory with filtering options:

• Inputs: Model, CLIP, directory path, search filters, strength settings
• Modes: Single, incremental, random
• Outputs: Modified MODEL, CLIP, filename

Image Batch Loader

Loads images with advanced filtering and index range selection:

• Inputs: Directory path, search filters, subfolder option, image list toggle, start_index, end_index
• Outputs: Single image, filename, image count, image list (when enabled)
• Features: 1-based indexing, range selection, incremental/single/random modes

TXT Batch Loader

Loads text files with content and filename filtering:

• Inputs: Directory path, search filters for filename and content, start_index, end_index
• Outputs: Text content, filename
• Features: 1-based indexing, range selection

Image Batch Saver

Saves images with companion text files and advanced options:

• Inputs: Images, text content, output path, naming options, append_frames, start_index, end_index
• Features:
  • Frame accumulation (append_frames, defaults to false)
  • Index range selection (1-based)
  • Multi-format support (PNG, JPG, GIF, WebP, TIFF, BMP)
  • Auto-converts to GIF when append_frames is enabled with unsupported formats
  • Custom naming patterns, workflow embedding, progress tracking

Video Batch Saver

Saves videos with customizable settings:

• Inputs: Videos, text content, output path, format, codec, naming options
• Features: Multiple formats (MP4, etc.), codec selection, preserves original FPS, companion text files, workflow metadata

Text Modify Tool

Modifies text content programmatically:

• Options: Whole text, prefix, or suffix modification
• Operations: Search/replace, delete operations
