ComfyUI Extension: LNL Frame Selector

LNL Frame Selector Introduction

The ComfyUI-LNL extension, developed by Late Night Labs, is designed to enhance video interaction within the ComfyUI framework. This extension allows you to upload, playback, and perform basic editing on video files directly within the ComfyUI environment. Whether you're an AI artist looking to incorporate video elements into your projects or need a streamlined way to handle video files, ComfyUI-LNL provides the tools you need to manage and manipulate video content efficiently.

How LNL Frame Selector Works

ComfyUI-LNL works by integrating video handling capabilities into the ComfyUI framework. It allows you to upload video files, play them back, and perform basic editing tasks such as setting in and out points for specific video sections. Think of it as a video editor embedded within your AI art toolset, enabling you to select and process specific frames or sequences from your videos.

Basic Principles:

1. Video Upload and Playback: You can upload video files and use standard playback controls (Play, Pause, Scrub, Rewind) to navigate through the video.
2. Editing Tools: Set in and out points to select specific sections of the video for detailed editing. You can also select individual frames for further processing.

LNL Frame Selector Features

Video Upload and Playback

• Upload Video: Easily upload video files into the ComfyUI environment.
• Playback Controls: Use Play, Pause, Scrub, and Rewind to navigate through your video. This is similar to using a standard video player but integrated within ComfyUI.

Editing Tools

• In/Out Points: Set start (in) and end (out) points to select specific sections of the video. This is useful for focusing on particular parts of the video without processing the entire file.
• Frame Selection: Choose individual frames for detailed editing. This feature is particularly useful for AI artists who need to work with specific frames.
• Output Frames with Handles: Export selected frames with additional handles for further processing. This allows for more precise control over the video content.

Audio Handling

• Include Audio: Optionally include the audio track from the video in your output. This is useful if your project requires synchronized audio and video.

LNL Frame Selector Models

Currently, ComfyUI-LNL does not include different models. It focuses on providing robust video handling and editing features within the ComfyUI framework.
