Index hold "0.0:" not working as expected

[felixniemeyer]

I'm expecting "0.0:" to hold that prompt until the idx of the next prompt.

However, I observe, that it holds for only one frame and then switches over to the next already.

Have a look at the prompts and the comfy output it produces:

The first prompt appears only on one line. I had expected it to go from 0.0 to 0.33.
Further, I had expected the second prompt to go from 0.33 to 0.5, third from 0.5 to 0.66, and fourth from 0.66 till the end.

These expectation are based on the text from the help box:

hold: Putting a colon after a single idx stops interpolation until the next provided index. Examples -> 0:, 0.5:, 16:

I looked into the code and found this function doing a lot of things related to "hold" and "holders":

ComfyUI-AnimateDiff-Evolved/animatediff/scheduling.py

Line 226 in 261fac8

def handle_prompt_interpolation(pairs: list[InputPair], length: int, clip: CLIP, options: PromptOptions):

The function is so large, I'm scared to investigate.

In the meantime, I'm using ranges instead of "hold" as a workaround:


you can see, that the first prompt is now used for more than 1 frame.

Thanks for the detailed report, I'll look into this soon
