Free AI Video Generator with Audio

Official FLUX.3 demo clip — picture and sound generated in one pass.
Many people searching for a free AI video generator with audio — or for text to video AI that is free and without a watermark — want to test the model before committing to anything. Flux 3 Video works that way too: a free account takes about ten seconds to create with an email, lands free starter credits in your balance automatically, and never asks for a credit card. A login is not a paywall — it simply keeps your credits, clips, and settings in one place between visits.
What you get for free
Free starter credits unlock the same Flux 3 video generator as paid plans — nothing is feature-gated.
Text to video: turn a written prompt into a finished shot
Image to video: animate a starting frame or a visual reference
Native audio: dialogue, ambience, and sound effects generated in the same pass as the picture
Up to 20 seconds per generation, chainable into longer multi-shot sequences
16:9, 9:16, and 1:1 aspect ratios for any platform
Multilingual dialogue that stays in sync with the performance
