Class 8 in motion

Watch the node demos actually run

Class 8 was the one night that only makes full sense in motion. These four clips, with audio, were recovered from the class recording before it expired. They play right here and live in the download too.

The node build, start to finish

38 minutes. Seb starts from a blank Krea canvas and builds his first node workflow live: the LLM node, image inputs, the Krea agent, and batch aspect-ratio edits. This is the demo the whole class was built around.

Two workflows and the video chain

21 minutes. The product-placement workflow and the video chain: a green-screened phone becomes a finished subway ad, three clips stitched end to end.

The nodes recap

6 minutes. Seb's own summary of when nodes are worth it and when a plain chat is enough.

The ComfyUI Japan demo

3.5 minutes. A look at ComfyUI, the open-source node tool Krea's canvas descends from.
