How it works

Generative video APIs bill per second of output and produce clips; avatar platforms sell minutes of presenter video on a plan. They are different products, so the comparison is a budget check, not a like-for-like.

The formula

api = minutes * 60 * per_second; plan = smallest Synthesia plan whose minutes cover the volume

Worked example

Questions

Why is Synthesia's minute count approximate?

Its page sells credits (100 a minute) plus a free allowance and states minutes as up-to figures; the plan rows use those figures.
