Heavy AI video users, how are you not burning through credits?

I've been making more AI videos lately and the credit system is honestly rough.

One prompt sounds good in your head, then the output comes back with weird motion, wrong style, random face changes, or something completely unusable. Then you try again, and before you know it you've used a ridiculous amount of credits just trying to get one clean clip.

Are people just budgeting for this now, or is there a smarter way to work? Would love to know what heavy users are doing to avoid wasting credits on failed generations.
