What exactly are you doing in your workflow? Please show a screenshot

[wenxini234]

This error occurred when adding animateLcm models

[Kosinkadink]

That's the i2v model, you must use the Apply AnimateLCM-I2V Model node to use it properly

[Kosinkadink]

I thought I had an error message that should appear when it's not used properly, but I guess something is off, I'll have the error properly appear at some point

[wenxini234]

Thank you very much, @Kosinkadink, I should have used the wrong model, I will try it with t2v animateLCM models
