This repository contains various nodes for supporting Deforum-style animation generation with ComfyUI. I created these
for my own use (producing videos for my "Alt Key Project" music -
youtube channel), but I think they should be generic enough
and useful to many ComfyUI users.
I have demonstrated the use of these custom nodes in this youtube video.
This custom node pack is currently not being updated. Stable Diffusion video generation is moving towards a different
workflow with AnimateDiff and Stable Video Diffusion. I decided to not try to update this node pack, but I am instead
creating a separate custom node pack here:
After startup, a configuration file 'config.json' should have been created in the 'comfyui-dream-project' directory.
Specifically check that the path of ffmpeg works in your system (add full path to the command if needed).
Upgrade
When upgrading, it is good to re-run the pip install command as specified in the install section. This will install any
new dependencies.
Configuration
debug
Setting this to true will enable some trace-level logging.
ffmpeg.file_extension
Sets the output file extension and with that the envelope used.
ffmpeg.path
Path to the ffmpeg executable or just the command if ffmpeg is in PATH.
ffmpeg.arguments
The arguments sent to FFMPEG. A few of the values are provided by the node:
%FPS% the target framerate
%FRAMES% a frame ionput file
%OUTPUT% output video file path
encoding.jpeg__quality
Sets the encoding quality of jpeg images.
ui.top_category
Sets the name of the top level category on the menu. Set to empty string "" to remove the top level. If the top level
is removed you may also want to disable the category icons to get nodes into existing category folders.
Flags to add an icon before and/or after the node name.
ui.category_icons
Each key defines a unicode symbol as an icon used for the specified category.
mpeg_coder.bitrate_factor
This factor allows changing the bitrate to better fit the required quality and codec. A value of 1 is typically
suitable for H.265.
mpeg_coder.codec_name
Codec names as specified by ffmpeg. Some common options include "libx264", "libx264" and "mpeg2video".
mpeg_coder.encoding_threads
Increasing the number of encoding threads in mpegCoder will generally reduce the overall encoding time, but it will also
increase the load on the computer.
mpeg_coder.file_extension
Sets the output file extension and with that the envelope used.
mpeg_coder.max_b_frame
Sets the max-b-frames parameter for as specified in ffmpeg.
Concepts used
These are some concepts used in nodes:
Frame Counter
The frame counter is an abstraction that keeps track of where we are in the animation - what frame is rendered
and how does the current frame fit into the current animation.
Curves
A curve is simply a node that produces a value based
