Description

An image to video ComfyUI workflow with the video model Wan Vace

Howto

Drag an initial image into the image node, adjust the prompt, and press queue. The rest should fit.

Description

An image to video ComfyUI workflow with the video model Wan Vace and a special lora called Causvid. Which reduces the creation time dramatically. It is based at the default template that you can find in ComfyUI. But with some modifications.

Note that upscaling better happens in an extra step. You can find example upscaling workflows in my article about video upscaling in comfyui: https://www.tomgoodnoise.de/index.php/video-upscaling-in-comfyui/

There are some collapsed Note nodes besides the important nodes. Click at them to expand them. Some contains valuable informations.

Time

The example video in 480p , the 14b model and the causvid lora off took 67 minutes.

The example video in 480p , the 14b model and the causvid lora on took 10 minutes.

The example video in 480p , the 1.3b model and the causvid lora off took 3 minutes.

Requirements

This workflow was generated with 16 gb vram. Minimum requirement is 12 gb vram. And you should not have fewer than 32 gb system ram. I was not able to create the 720p version of the video with just 16 gb vram and my 32 gb ram.

AI-generated commentary

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

Purpose

  • Use Wan 2.1 Image to Video in ComfyUI to turn an initial image and prompt into a 480p video with Wan Vace.

Flow

  • Drag an initial image into the image node, adjust the prompt, and press queue to start video generation.

Inputs and outputs

  • Provide an initial image and prompt; the workflow produces a video.

  • If you want to upscale the video, plan upscaling as a separate extra step.

Setup

  • The stated minimum is 12 GB of VRAM and 32 GB of system RAM; the workflow was generated with 16 GB of VRAM.

Dependencies

  • Model files listed for the workflow include umt5_xxl_fp16.safetensors, wan_2.1_vae.safetensors, wan2.1_vace_1.3B_fp16.safetensors, and wan2.1_vace_14B_fp16.safetensors.

  • LoRA files listed for the workflow are Wan21_CausVid_14B_T2V_lora_rank32.safetensors and Wan21_CausVid_bidirect2_T2V_1_3B_lora_rank32.safetensors.

  • Node packs listed for the workflow are comfyui-frame-interpolation, comfyui-kjnodes, and comfyui-videohelpersuite.

Configuration

  • The workflow includes 14B and 1.3B model variants and a CausVid LoRA that can be on or off.

  • The description reports 480p example times of 67 minutes with the 14B model and CausVid off, 10 minutes with 14B and CausVid on, and 3 minutes with 1.3B and CausVid off.

  • Expand the collapsed Note nodes to read their additional information.

Cautions

  • Before running, verify that ComfyUI has the listed model files, LoRA files, and node packs available.

    Suggestion · not verified

  • For 720p, verify your hardware first: the provided details say the 720p version could not be created with 16 GB of VRAM and 32 GB of system RAM.
