I used to use A1111 extension called prompt-travel. I did not find anything like that for ComfyUI so decided to make it myself.

This workflow allows for probably any image generation model since you can just toggle cfg and negative prompt on and off. Some models do not work without cfg and negative prompt while others can or do work without. Turning it on doubles time however.

Settings:
on top below the giant wall of text you have the CFG settings and to the left of it settings to video framerate

Then there is positive and negative prompt. I decided that 4 is a good count there. More could be possible but I decided it to be unneeded. It would be possible to even make procedural but even now I have a headache thinking just thinking about the math

Next is timing setting below that. It is the meat of this. It allows 8 different curves and 4 time compression settings. From off to pow(5).

Below that is image count. Self explanatery. It is set to 300 which can take a LOOONG time. Over an hour on a 5090. There should be ETA in console.

To the left of it is Adaptive module settings. For the first time I recommand keeping it off. Turning it on requires at least 41 images. (did not test with less then 60 images)

Below you can set seed for each point. Be carefull some curves just do not work with noise and will result in grey.

Also on top you can select model and even exchange nodes when using model requiring more CLIP models or exchange it entirly for a checkpoint loader when you want to use SDXL or simillar.

The right side:

Be carefull. The right side can be laggy after generationg. On top you have your video output, on the bottom you have all imades it generates (the source of lag) and in the middle you have a graph which shows you the density of output. Does not show exactly reality when adaptive stages are off becouse the circullar corners.
