#### Tips for AI Video nodes

* **Image-to-video is often better than text-to-video**: generate a still image first with Generate Image, then animate it with Generate Video. You get much more control over the visual.
* **Extract Video Frame** is useful as a bridge — pull a frame from a video to use as input for image editing or as a reference for generating new content.
* **Lipsync works with both video and still images**: you can animate a static portrait photo into a speaking character.
