AI-generated commentary

AI-generated explanation based on source and configuration details. Suggestions are clearly labeled.

Purpose

  • This workflow is for making long videos of someone talking or singing with alternating shots. Its inputs include uploaded audio, a video path, and multi-image prompts, and its video-combine step produces video.

Flow

  • The workflow file includes nodes for prompt looping, cross-dissolves, audio merging, and audio chunking.

Inputs and outputs

  • Named nodes include VHS_LoadAudioUpload, VHS_LoadVideoPath, TKMultiImagePrompt, and VHS_VideoCombine for audio upload, video-path loading, multi-image prompts, and video assembly.

Setup

  • The author says this workflow requires custom nodes called TK Handy Nodes.

Dependencies

  • The listed node add-ons include basic_data_handling, comfy-mtb, comfyui-easy-use, ComfyUI-GGUF, comfyui-gguf-reboot, comfyui-handynodes-kt, and comfyui-kjnodes.

  • Other listed entries are ComfyUI-LTXVideo, ComfyUI-MelBandRoFormer, comfyui-videohelpersuite, GetNode, kijai/ComfyUI-KJNodes, Label (rgthree), rgthree-comfy, and SetNode. Confirm which add-ons provide GetNode, Label (rgthree), and SetNode before setup.

    Suggestion

  • The listed model files are gemma4-12b-with-proj-ltx-2.5-Q5_K_M.gguf, LTX-2.5-Distilled-Q4_K_M.gguf, ltx-2-spatial-upscaler-x2-1.0.safetensors, ltx-2.5-audio-vae-bf16.safetensors, ltx-2.5-video-vae-bf16.safetensors, and MelBandRoformer_fp16.safetensors.

Configuration

  • If you use lip sync frequently, the author suggests LTX 2.5; the v6.0 description says the workflow was updated for 2.5 and switched to a convrot Gemma text encoder.

    Suggestion

Cautions

  • The title says LTX 2.3, while the summary and listed base model say LTX 2.5; check the source page before choosing files.

    Suggestion

  • No direct file URL is listed for gemma4-12b-with-proj-ltx-2.5-Q5_K_M.gguf or LTX-2.5-Distilled-Q4_K_M.gguf; confirm their download locations before setup.
