A simple workflow that allows to use AnimateDiff with Prompt Travelling. You will need the AnimateDiff-Evolved nodes, the motion modules and any stable diffusion v15 model.
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, 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"
Where each number corresponds to the position of the frame in the final animation; this means that AnimatedDiff will try to create transitions between each prompt.
