About FLUX 3 Max Video
FLUX 3 Max Video is the Max variant of the FLUX 3 video model from Black Forest Labs, priced at $0.43 per second. It runs as text to video, image to video and start and end frame, with audio, from 5 seconds to 20 seconds, at 720p and 1080p.
The difference is in how it works rather than in the controls: it spends effort reasoning about the prompt before it renders. A typical generation takes about 4 min, against about 3 min for FLUX 3 Video.
Good for
- Complex scenes where the prompt has many parts, since the model reasons about the prompt before rendering
Getting good results
- With the shape on automatic, text prompts come out landscape and image prompts follow the first image, according to the provider.
- Allow more time than FLUX 3 Video, since reasoning comes first; the provider notes that more reasoning means slower generation.
