STEP 1 — Set Up ComfyUI with a GPU
To make videos in ComfyUI, you need access to a GPU. The easiest method is using a service like RunPod, where you can rent one cheaply. Load a pre-built workflow (such as version 1.2.2) so you don’t have to configure everything manually. This setup lets you generate videos locally without relying on expensive platforms.
STEP 2 — Download the Right LoRA Models
Your results depend heavily on the models you use. For video generation, you need LoRAs for consistency. Most workflows require both a high noise LoRA and a low noise LoRA. These work together to produce stable outputs. If they are missing or mismatched, your workflow will either fail or generate poor results.
STEP 3 — Set Up the Workflow
Upload your base image (your character), then assign the models correctly. The high noise model goes at the top, and the low noise model goes at the bottom. Load your LoRAs into the correct nodes. This step is critical—if something is placed incorrectly, the video won’t render properly.
STEP 4 — Use Proper Prompting
Each LoRA comes with specific trigger words. These must be included in your prompt or the model won’t activate correctly. Start with simple prompts using the trigger words, then add details later once everything works. Overcomplicating prompts early usually leads to worse outputs.
STEP 5 — Generate the Video
Start with lower resolution (like 480p) to test quickly. Once everything works, increase to 720p for better quality. Higher resolution improves realism but increases render time, so it’s best to test first and scale up after.
STEP 6 — Upscale the Output
After generating your video, use an upscale step to improve sharpness and detail. This significantly enhances realism. It takes more time, but the difference in quality is noticeable and usually worth it.
STEP 7 — Fix Common Issues
Most problems come from incorrect setup. Errors usually mean the high/low noise models are mismatched. Poor quality outputs often come from wrong LoRAs or missing trigger words. If downloads are slow, use direct links instead of uploading files manually.
STEP 8 — Understand the Process
Not every generation will be usable. It’s normal to run multiple attempts before getting a good result. Quality improves over time as you refine your inputs, models, and prompts. Expect iteration.
STEP 9 — Find Better Models
You can find better LoRAs and video models on open-source platforms. Look for ones focused on video generation and character consistency. New models are released constantly, so staying updated gives you an advantage.
