ComfyUI Extension: Dream Video Batches

Dream Video Batches Introduction

The comfyui-dream-video-batches extension is a custom node pack designed for ComfyUI, aimed at enhancing video production workflows, particularly for AI artists working with AnimateDiff and Stable Video Diffusion. Created by the author for their own video production needs, this extension offers a variety of utilities that can be beneficial for others in the AI art community. Whether you're looking to create smooth transitions, manipulate frame sets, or add camera movements, this extension provides the tools you need to bring your video projects to life.

How Dream Video Batches Works

At its core, comfyui-dream-video-batches operates by manipulating frame sets—collections of images that make up a video. Think of a frame set as a flipbook, where each page is a frame, and flipping through them quickly creates the illusion of motion. The extension provides nodes that allow you to perform various operations on these frame sets, such as blending transitions, adding fade effects, and animating camera movements. By connecting these nodes in ComfyUI, you can build complex video workflows without needing to write any code.

Dream Video Batches Features

Blended Transition [DVB]

• Description: Fades from one frame set to another over a specified number of overlapping frames.
• Customization: You can specify the number of frames over which the transition occurs, allowing for smooth or abrupt changes.

Calculation [DVB]

• Description: Provides arithmetic operators and common mathematical functions.
• Customization: Useful for performing calculations within your workflow, such as adjusting frame rates or scaling factors.

Create Frame Set [DVB]

• Description: Creates a frame set from an image batch and a specified frame rate.
• Customization: Define the frame rate to control the speed of your animation.

Fade From Black [DVB]

• Description: Adds a fade-in effect from black at the beginning of a frame set.
• Customization: Adjust the duration of the fade-in to match your artistic vision.

Fade To Black [DVB]

• Customization: Similar to Fade From Black, you can control the duration of the fade-out.

Linear Camera Pan [DVB]

• Description: Performs a constant velocity pan within a frame set.
• Customization: Define the start and end points of the pan to create dynamic camera movements.

Sine Camera Zoom [DVB]

• Description: Creates an oscillating zoom effect using a sine wave.
• Customization: Adjust the amplitude and frequency of the zoom to achieve the desired effect.

Generate Inbetween Frames [DVB]

• Description: Adds in-between frames to fill gaps in a frame set.
• Customization: Specify the number of in-between frames to create smoother animations.
