As I see your answers about the credit usage / consumption your plan give VERY LOW amount of credits which allow make only 2-3 videos with 3-5 minutes long each per moth.
Your Tier3 gives 8,000 credits / month.
So if I go with 5 minutes video in high quality than I can make 2 videos a month only?
As you said:
"• A 3-minute video usually consumes around 1,000–3,000 credits depending on the number of animated scenes and effects.
• A 5-minute video can take about 2,000–4,000 credits if fully animated with multiple scenes."

There are so many potential and promise in the future in your service but ......
2 videos a month??? REALLY???
