Explicação gerada por IA com base nos detalhes da fonte e da configuração. As sugestões são claramente identificadas.

Propósito

  • This ComfyUI workflow creates video from a text prompt or image, with text-to-video, image-to-video, lip-sync, and LTXV-audio or custom-audio paths; its title advertises 1080p and 4K video.

Fluxo

  • The walkthrough loads an LTX Safetensor or GGUF model, then shows text-to-video and image-to-video examples, including LTXV Audio and custom audio.

Entradas e saídas

  • A text prompt or source image selects the video path; the walkthrough also names LTXV Audio and custom-audio variants, and the title names video and lip sync.

Configuração

  • Before opening the workflow, the notes ask you to update or download ComfyUI-Monnky-LTXV2, ComfyUI-KJNodes, and ComfyUI-LTXVideo.

  • If MonnkySamplerLTXV is missing, the notes say it cannot be installed through the standard ComfyUI Manager search; remove prior ComfyUI-PainterLTXV installs, clone ComfyUI-Monnky-LTXV2 into ComfyUI/custom_nodes/, and restart ComfyUI.

Dependências

  • The workflow lists these node dependencies: ComfyLiterals, comfymath, comfyui-custom-scripts, comfyui-easy-use, ComfyUI-GGUF, comfyui-impact-pack, comfyui-kjnodes, ComfyUI-MelBandRoFormer, and comfyui-videohelpersuite.

  • It also lists Fast Groups Bypasser (rgthree), GetNode, Label (rgthree), LowVRAMLatentUpscaleModelLoader, LTXVSpatioTemporalTiledVAEDecode, monnky/ComfyUI-Monnky-LTXV2, rgthree-comfy, and SetNode.

  • Listed model files are gemma_3_12B_it_fp8_e4m3fn.safetensors, ltx-2-19b-distilled_Q4_K_M.gguf, ltx-2-19b-distilled-fp8.safetensors, ltx-2-19b-distilled.safetensors, ltx-2-19b-ic-lora-detailer.safetensors, ltx-2-19b-lora-camera-control-dolly-left.safetensors, ltx-2-spatial-upsc in

Configuração

  • In the walkthrough, LTXV Audio paths and text-to-video with custom audio use an FP8 distilled model; image-to-video with custom audio uses a Q4 GGUF model.

  • Embedded size notes pair Low VRAM 640 x 360 with 1280 x 720 (720p HD), Mid VRAM 960 x 512 with 1080 x 1024 (Full HD), High VRAM 1280 x 704 with 2560 x 1408 (2K), and Very High VRAM 1920 x 1024 with 3840 x 2048 (4K).

  • Version 1.1 notes audio normalization as a change to sound generation.

Precauções

  • The listing does not specify a license for using the model.
