FLUX.3 Keyframes to Video by Black Forest Labs lets you steer a shot precisely: pin up to 10 keyframe images to exact frame positions on a 24 fps timeline and it animates through them in order, generating motion and matching audio between each. Describe the action and sound, and keep your keyframes consistent for the cleanest result. Choose a duration from 5 to 20 seconds at 720p or 1080p in aspect ratios from 21:9 to 9:16. Ideal for staged sequences, time-lapses, transformations and any shot that must hit specific beats.
