Getting Started

Recommended runtime: ComfyUI with video nodes

Install ComfyUI and add the ComfyUI-VideoHelperSuite custom nodes.
Download a lightweight video model (e.g., Wan 1.3B or LTX Video 2B distilled).
Set frame count to 16-25 frames at 8 fps for a 2-3 second clip.
Use a concise prompt describing the motion and scene — short clips need clear direction.
Export as MP4 or GIF for social media use.

Frequently Asked Questions

What is the fastest AI video generation model for local use?▼

LTX Video 2B distilled and Wan 1.3B are the fastest options. LTX Video 2B can generate a 2-second clip in under 30 seconds on an RTX 4090. Wan 1.3B offers a good balance of speed and quality at low VRAM usage.

How much VRAM do I need for short AI video clips?▼

For short clips (16-25 frames at 512p), lightweight models like Wan 1.3B need around 6-8 GB VRAM. LTX Video 2B works well with 8-12 GB. Larger models like CogVideoX 5B need 16 GB+ even for short clips.

Can I generate AI video loops for social media?▼

Yes. Generate a short clip and use video editing tools to create seamless loops. Some models produce more loop-friendly output with prompts that describe cyclical motion (e.g., 'waves crashing', 'fire flickering').
