Questions
1What does a FLUX.3 Video clip cost?
260 credits per second of video: a 5-second clip is 1,300 credits and a 15-second clip is 3,900. If a run fails, the credits go back to your balance; runs stopped by the model's safety filter are refunded up to 10 times a day.
2Which lengths, sizes and frames does FLUX.3 Video take?
Clips of 5, 10 or 15 seconds, in 16:9, 9:16, 1:1, 4:3 or 3:4. You can add a start frame, or a start and an end frame (PNG, JPEG or WebP, up to 12 MB each), and FLUX.3 Video animates between them; without frames it works from text.
3Can I use what I make with FLUX.3 Video in paid work?
Yes, when you made it on a paid plan or after buying credits. Results made only with the free sign-up credits are for personal, non-commercial use. Anything you upload must be yours to use, and people shown in it must have agreed.
