Hi there! I just started using krita..and I loved it...just a problem, in the export animation window, there is the field for end frame, and it can get 100 but I can not write a number higher...lets say 300...is it normal? is it a real Krita limitation..not export longer animations? or is it just me? thank you!!

The maximum in the export dialog is taken from the play range in the animation docker. If you make that bigger, the export number will be bigger.
