Add low-risk NVENC encoding option to ImageTransitionNode, VideoImageOverlay,
and VideoSplitterNode. Each node now includes a use_gpu parameter (default: False)
that enables hevc_nvenc when available, with automatic fallback to libx264 if
NVIDIA GPU is unavailable or NVENC fails.
Changes:
- ImageTransitionNode: Add use_gpu parameter for MP4 frame encoding
- VideoImageOverlay: Add use_gpu parameter for overlay video encoding
- VideoSplitterNode: Add use_gpu parameter for segment encoding
Expected gains: 5-10x speedup for GPU users (hevc_nvenc vs libx264)
Risk level: VERY LOW (zero breaking changes, backward compatible)

Image Processing (PyTorch GPU tensor operations):
- ZoomSequenceNode: Add device handling for GPU-accelerated F.interpolate
- CameraShakeNode: Ensure tensors stay on GPU device
- CameraMoveNode: Add device handling for GPU acceleration
- Expected gain: 4-10x speedup for large batches
Video Encoding (NVENC support):
- VideoLoopExtenderNode: Add use_gpu parameter for HEVC_NVENC encoding
- Falls back to libx264 if NVIDIA GPU unavailable
- Expected gain: 5-10x speedup for video encoding
Note: ComfySimpleVideoCombiner and ColorAdjustmentVideoNode already had
GPU support implemented, so no changes were needed.
Safe, backward-compatible changes with runtime GPU detection and fallback.

pure PyTorch — no FFmpeg round-trip. Supports Horizontal, Vertical, and
Diagonal directions with four channel-polarity presets and RGBA safety.

Document the updated Zoom Sequence and Batched Zoom Sequence interfaces, including new `direction`, `amount_type`, `zoom_percentage`, `random_seed`, and `smooth_subpixel` inputs, plus Random easing support.
Clarify how random selection works per execution (and how `random_seed=0` forces fresh rolls) and explain subpixel sampling vs integer crop modes so users can get smoother long/slow zooms and reproducible results when needed.docs(readme): expand zoom node options and random-mode behavior

- Moved all script modules into a new `scripts/` folder
- Updated import statements in `__init__.py` to reference the new folder
- Updated README installation instructions to reflect the new structure for better codebase organization
- Update README.md to accurately describe output_path as a single path for non-recursive mode or newline-separated list for recursive mode
- Set RETURN_TYPES to ("STRING",) in ComfySimpleVideoCombiner to match the output type
Add a new `recursive` boolean parameter to enable processing subdirectories recursively. When enabled, the node scans for subdirectories, concatenates videos in each separately, and outputs a newline-separated list of paths. This improves handling of organized video collections by creating distinct outputs per folder. Refactored code for clarity with a helper method for single-directory processing. Updated README with detailed mode descriptions.
Add a new node that generates CSV files pairing image and audio files from separate directories. This enables users to create datasets for machine learning, organize media for batch processing, and automate file cataloging by sorting and zipping file lists alphabetically. Includes support for common image (PNG, JPG, etc.) and audio (MP3, WAV, etc.) formats, with semicolon-delimited output and UTF-8 encoding. Updates include importing the node in __init__.py and adding comprehensive documentation to README.md.
- Add new ComfyAddSoundtrack node for mixing soundtrack audio with video while preserving original audio, including volume adjustment, trimming, and optional original file deletion
- Update ComfySimpleVideoCombiner to include cross-fade duration parameter for smoother video transitions
- Enhance README with detailed documentation for the new soundtrack feature, improving user guidance and node discoverability
- Register new node in __init__.py mappings for proper integration into ComfyUI workflow
This expands audio/video processing capabilities, allowing users to create richer multimedia content with professional audio mixing and seamless video edits.
Refactored the video combining logic to handle video and audio streams separately, normalizing audio to 44100 Hz stereo to prevent mismatches between clips with different sample rates or channel layouts. Replaced concat demuxer with interleaved stream concatenation for better compatibility and robustness. Added _get_video_duration method for probing video durations using ffprobe. Removed temporary file handling for simpler implementation. This improves reliability when combining videos with varying audio properties.
