FLUX 3 is best for natural motion from a text prompt or a single still, especially when you want optional audio and a clip longer than 15 seconds, or when you want to restyle an existing MP4 with Edit clip. ### Can FLUX 3 animate images? Yes. Video Lab supports a starting image or first-to-last-frame direction. Multi-image references are not available. ### Can FLUX 3 edit an existing clip? Yes. Choose Edit clip on FLUX 3, pick a library clip or upload an MP4, then describe the change. Clips must be MP4, under 15 seconds and 50 MB. Lip sync follows new dialogue, including translations. Duration and aspect follow the source. Output is 720p and keeps the source clip’s audio unless you rewrite or translate the dialogue. ### How is FLUX 3 Edit clip priced? Edit clip uses this month’s generation limit based on the source clip’s length. Failed generations return that usage to the limit. ### How long can FLUX 3 videos be? Text, animate, and first-to-last shots support 5 to 20 seconds at 720p or 1080p. Edit clip uses the source MP4’s runtime, up to 15 seconds. ## Make a story using this model's shots Paste a story or script.
