A simple workflow that allows to use AnimateDiff with Prompt Travelling. You will need the AnimateDiff-Evolved nodes and the motion modules.

I had the best results with the mm_sd_v14.ckpt AnimateDiff module, it makes the transition more clear. The longer the animation the better, even if it's time consuming. I would say to use at least 24 frames (batch_size), 12 if it's just for testing.

The structure of the prompt is as follows:

"0": "blue background",

"8": "eyes of fire, orange background",

"16" :"face on (fire:1.4), red background",

"24" :"Made of flames, full fire"

You can choose a pre_text or app_text to keep a fixed part of the prompt before or after each prompt associated with a frame. More details in this article.
