ComfyUI Image to Video: Full Review, Challenges & Simple Fix

What is ComfyUI video generation

ComfyUI is an incredible, open-source, node-based graphic user interface for AI image and video generation. ComfyUI is popularly known and widely recognized among experienced developers for its ability to create complex workflows. It offers high-quality video generation results with the use of various models like AnimateDiff, HunyuanVideo, LTX Video and Wan2.1. While ComfyUI provides professional results, it might be accompanied by some challenges in the form of a steep learning curve, custom software downloads, and top-end hardware and memory requirements.

How to create videos with ComfyUI image to video workflows

ComfyUI provides several methods for image-to-video generation, each using unique models and node setups. These methods mainly include AnimateDiff, HunyuanVideo and LTX Video. However, they all require special setup processes and technical knowledge. Here, we will break down the 3 major methods along with their step-by-step procedures.

Method 1: ComfyUI AnimateDiff image to video workflow

STEP 1
1. Set Up ComfyUI and Install Nodes

To get started, download ComfyUI and extract it. Use ComfyUI or a git clone to install the core animation code packs. After installing, update ComfyUI and ensure that the animation-related modules are visible and loadable when you launch it.

STEP 2
1. Load Models and Upload Image

After launching, place your preferred AnimateDiff checkpoints in the checkpoints folder. You also have to download and add motion modules into the correct model folders. Add ControlNet models using Vid2Vid and place their files in controlnets/. In the Graphic User Interface, load the AnimateDiff workflow. After loading the workflow, load the image.

STEP 3
1. Assemble the AnimateDiff workflow

Define the source frames and how many to load. After that, input your motion module, frame count and preferred context settings. You can also choose to add map poses and depths using the ControlNet nodes to guide the motion. Use the BatchPromptSchedule option to vary prompts per frame. Select your sampler type, steps and denoising strength with the KSampler.

STEP 4
1. Generate and Export

After making all your preferred selections, you can now hit "Queue Prompt" to assemble the frames into a video or GIF using AnimateDiffCombine. ComfyUI will generate each frame with AnimateDiff. After generation, the Combine node will merge all frames smoothly into a playable video format. Review your video and select the MP4 format to download.

Method 2: ComfyUI HunyuanVideo image to video generation

STEP 1
1. Prepare your Image

After installing ComfyUI, you have to prepare your image to meet Hunyuan's requirements. HunyuanVideo expects images in a particular format and resolution. Resize your image to 512 x 512 pixels to fit the upload requirements for HunyuanVideo.

STEP 2
1. Generate your Caption

Caption generation is critical as Hunyuan's performance heavily depends on accurate captions. Use the Florence2Run model to generate your captions. After generating, modify your captions by using the StringReplace node to replace any word like "image", "photo", "painting" or "illustration" with "video", as HunyuanVideo is trained to understand video descriptions.

STEP 3
1. Convert Image to Hunyuan's Latent Space

The latent space is a format that Hunyuan can effectively process. It captures the essential features of the image, allowing Hunyuan to manipulate for effective generation. Add Latent Space by uploading the HunyuanVideo Sampler node. Link the samples between the wrapper nodes to convert the format.

STEP 4
1. Integrate Model and Generate

Use the HunyuanVideo Lora Select node to guide Hunyuan to add motion to static images. After configuring your node, connect all HunyuanVideoWrapper consoles to the HunyuanVideo Sampler node. The sampler takes all the process information, encoded image, edited prompt and Lora guidance and generates the final video output. After generation, go to the Video Combine node and save your video.

Method 3: ComfyUI LTX Video workflow setup

STEP 1
1. Install LTX Video and Set up Environment

Start by installing the latest version of ComfyUI that supports LTX nodes. After that, install ComfyUI-LTXVideo custom nodes and models using the Manager or clone them manually from GitHub. These models include the main video model from Safetensors and the text encoder from PixArt-XL.

STEP 2
1. Write your prompt and Set Video Resolution

After all downloads and installations, write your prompt in the CLIP Text Encode node. After you fill in your prompt, you can now set the video resolution using the EmptyLTXVLatentVideo node, choosing the resolution you prefer and your device can carry.

STEP 3
1. Configure Image Detail and Video Settings

The steps value in your LTXVScheduler node controls the image details in your video, with higher steps meaning higher quality but slower processing speed. Select a value that you prefer. The LTXVScheduler also controls other video settings. For example, the max_shift, base_shift, stretch and terminal values determine if your video is going to have an action-paced dynamic movement or a slow, calm ambiance.

STEP 4
1. Configure Save Settings and Generate

After modifying image details, go to the SaveAnimatedWEBP node to select your save settings. Change the filename_prefix to LTX. Change the Lossless value from False to True and set the quality to 100. Once you're done with the configuration, click on Queue at the top right of the screen to generate.

ComfyUI video review: Is it worth the struggle

ComfyUI is widely recognized as a powerful tool for image-to-video generation. Its modular, node-based interface offers designers near-limitless power over their workflow. However, with great power comes great responsibility, or in this case, great complexity. Let's dive into ComfyUI's strengths and limitations to help you decide if it is the best fit for you.

From these pros and cons, it is undeniable that ComfyUI is a powerful machine, but only in the right hands. ComfyUI is an open-source tool that offers you complete control over your project due to its node-based system and model support, making it an ideal tool for experienced developers doing advanced generation. However, it fails to meet the needs of casual users with budget devices who prioritize speed and ease of use, due to its complicated setup, steep learning curve and heavy hardware requirements. For such users, Dreamina offers a better alternative. In the next section, we will discuss how Dreamina works and why it is a better, more suitable video generation alternative.
