ComfyUI: Image-to-Video with LTX 2.3
ComfyUIDemo summary
The creator demonstrates bringing a static image of a vampire warlord to life by using an image input node and a descriptive prompt to guide the animation and environmental effects.
Step-by-step
- Drag the image-to-video workflow into ComfyUI.
- Upload your source image into the image input node.
- Set the frame counter (e.g., 121 frames for 5 seconds or 169 frames for 7 seconds).
- Adjust the image scaling by the longer edge (start at 640 for stability).
- Enter a descriptive prompt including shot size, subject details, setting, and specific actions/dialogue.
- Set the LTX image-to-video strength to 1.0 or 0.9 to ensure the output sticks to the original image.
- Click Run to generate the video.
Options
- Increase image scaling to 1080 if using a high-end GPU like a 5090.
- Add audio directions and atmosphere descriptions to the prompt for integrated sound generation.
Watch out for
- Setting the image scaling too high can crash ComfyUI or your PC (Blue Screen of Death).
- High frame rates combined with high resolution can lead to GPU failure or crashes.
Tips
- Start with a low scaling value like 640 if you are unsure of your GPU strength.
- Describe what is already in the image within the prompt to help guide the animation.
- In LTX 2.3, use a strength of 1.0; unlike LTX 2.0, it will not cause the video to get stuck in place.
