A bit more advanced, but maybe worth a separate note is the difference in the latent between inpainting and outpainting.

Inpainting: Sends the original image as the latent.
Outpainting: Sends the original image + a grey border as the latent.

When you get a harsh seam after outpainting, the reason is because the "Pad Image For Outpainting" node doesn't fill the extended area with any surrounding color data. Instead, it fills it with a neutral gray and calls it a day.

Some custom nodes address this, but there's no easy way to address it in core comfy as of this post.
