I wanted to know for the starter formula how many 180 seconds/months is it because I don't understand? and is it possible to delete the seconds used and make other animations or the second used will mark the end of my formula without the possibility of starting new animations?
The Starter plan grants you 180 seconds of animation time per month to use. You can download the result animation unlimited times from your "Library". Deleting the result animations from your "library" will do nothing to your already used animation time. If you have used up all the 180 seconds of animation time of the current month you can 1) wait until the next month when your animation time is refilled to 180 seconds or 2) upgrade to a higher tier of plan and get new animation time instantaneously.
