How to Generate AI Videos for FREE with ComfyUI (Step-by-Step Tutorial)

About this video

Kevin Stratvert walks through installing ComfyUI on a Windows PC and using it to generate AI videos locally for free, with no API keys, subscriptions, or usage credits. He downloads the desktop version, selects local installation, and recommends a Windows PC with an NVIDIA RTX graphics card. In the Video section he filters models to those that run on ComfyUI itself and by the text-to-video task, then chooses LTX 2.3 for its speed, quality, and wide RTX compatibility. ComfyUI flags missing models — about 40 GB total in his case — which he downloads once via Download All. He then enters a descriptive prompt for a Kevin Cookie Company blimp over a city at golden hour, leaves resolution, duration, and frame rate at defaults, and clicks Run, noting the result looked more like a cross between a hot air balloon and a blimp. He also shows image-to-video by dragging in a blimp image and prompting the motion, and notes generated content is saved and accessible via Assets. He closes by noting other workflows for video editing, camera control, inpainting, and upscaling, and other models to experiment with.

Key takeaways

• ComfyUI is free and open-source and runs AI models locally on your own PC, avoiding per-video charges, API keys, and subscriptions after installation
• The tutorial recommends a Windows PC with an NVIDIA RTX graphics card and using the desktop, local installation of ComfyUI
• Filtering by Runs On: ComfyUI and Task: Text to Video isolates free local models; LTX 2.3 is chosen for speed, quality, and broad RTX support
• The LTX 2.3 workflow requires downloading missing models first — about 40 GB in the example — which only needs to be done once
• The same LTX 2.3 models support image-to-video: drag in a starting image, describe the desired motion in a prompt, and click Run
