FLUX.3, from Black Forest Labs, makes video guided by frames. Besides start and end frames, you can place keyframes at points in between, so you decide what the video shows and when. Choose a tier under Tier:
  • Standard, the default.
  • Max follows prompts more closely and renders faster, and adds Reasoning. It can’t extend a video.
FLUX.3 selected in the video generator, with the Standard tier and Frames slots for Start at 0 s, Keyframe and End at 5 s, and one References slot.

​
What you can give it

  • A prompt on its own.
  • Frames: a start frame, and an optional end frame.
  • Keyframes: up to 10 PNG, JPEG or WebP images in all, counting the start and end frames. Choose Keyframe under Frames, pick an image, then type the time it should appear, in seconds. Times land on the video’s 24 fps frames and must fall within its duration.
  • Extend (Standard): one MP4 video of up to 15 seconds to continue, added under References.

Cost

FLUX.3 is priced per second of video, by resolution. Keyframes cost the same per second, and extending a video costs more. A 5-second 720p video on the Standard tier costs about $1.11. Max has a promotional price through November 7, 2026, and costs the same as Standard after that. Prices are as of October 28, 2026. For FLUX.3 images, see FLUX.
