Question 1

What is AI video generation with ComfyUI?

Accepted Answer

AI video generation in ComfyUI creates animated content from text, images, or existing videos using models like AnimateDiff, SVD (Stable Video Diffusion), and Mochi. Workflows can generate short clips, animate still images, or apply effects.

Question 2

What video durations and frame rates are supported?

Accepted Answer

Most video workflows generate 2-6 second clips at 8-24 FPS due to VRAM constraints. AnimateDiff typically produces 16-32 frames, while SVD generates 14-25 frames. Longer videos require frame interpolation or segment stitching.

Question 3

What are the hardware requirements for video generation?

Accepted Answer

Video generation is VRAM-intensive, requiring 12GB+ for AnimateDiff and 16GB+ for SVD/Mochi. Batch processing and temporal attention increase memory usage compared to image generation.

Question 4

What video formats does ComfyUI output?

Accepted Answer

ComfyUI outputs video as image sequences (PNG frames) or encoded MP4/GIF using video combine nodes. H.264 MP4 is common for sharing, while PNG sequences preserve quality for editing.
