Same error, I decided to assemble a 1500€ PC because this script's results looked so good (when it works). I even tried to modify the line of code associated with the error in order to remove the "8lqje9jfr" by replacing the 77th line of code by this:
p.control_net_input_image = Image.open(reference_imgs[i].name.replace("\\\\", "\\")[:-12] + reference_imgs[i].name.replace("\\\\", "\\")[-4:]).convert("RGB").resize((initial_width, p.height), Image.ANTIALIAS)
but that's not it.
Tried different image sequence renderers as I thought the images where faulty, I doubt it is.
Tried jpeg, png, not it.
I tried with and without controlnet still no.
Maybe it was the resolution I made sure it all matched, not it.
I will use the standard control net for animation for now until it's solved.
