Approximate cost per video clip
What does a credit buy you?
A 1080p 6 second clip costs 80 credits; a 768p 6 second clip costs 25 credits. On the Standard plan ($9.99/mo, 1,000 credits) you get roughly 12 clips at 1080p or 40 at 768p. The Pro plan ($34.99/mo, 4,500 credits) stretches to about 56 clips at 1080p. Use 768p for iteration, then render final versions at 1080p to save credits.
