FranckyB Simplifies AI Video Workflows with ComfyUI-FBnodes

Video tap joined with golden string

ComfyUI-FBnodes is a collection of custom nodes for ComfyUI that streamlines video workflows and adds utility functions for AI content generation. The extension provides tools for video encoding with codec controls, file browsing with thumbnail previews, and AI-powered transition generation between clips.

Developer FranckyB created these nodes to solve common workflow friction points in personal projects before sharing them with the community. The toolkit addresses practical needs like video saving with metadata embedding, clip management, and workflow branching with conditional logic

Workflow enhancements and video tools

  • Save Video+ node with H.264 or H.265 codec support, quality control via CRF, and audio muxing.
  • Load Image+ and Load Video+ nodes featuring built-in file browsers with subfolder navigation.
  • VACE Stitcher for generating smooth AI-powered transitions between video clips using 2-stage sampling.
  • Animated Latent Preview showing video previews during sampling for models like Wan and HunyuanVideo.
  • Universal Switch Any node with lazy evaluation that only processes the selected input branch.
  • Apply LoRA+ node for managing LoRA stacks across models and CLIP.

Video creators working with generative AI will find the VACE Stitcher particularly useful for combining multiple clips without manually creating transitions. The caching system saves computed transitions as latent files, allowing users to re-run workflows and skip already-generated pairs for efficiency.

From personal tool to community release

FranckyB initially built these nodes for personal workflows before releasing them publicly. The VACE Stitcher was inspired by a workflow shared by Reddit user goddess_peeler that automated clip stitching.

'I plan on exposing some of these to the comfy preferences, so we could make changes to what the defaults are,'

the developer wrote regarding future updates.

The extension requires PyAV for video encoding and integrates with ComfyUI Manager for straightforward installation. Users can also install manually via git clone, with the project released under GPL-3.0 licensing.
