Flux3Max.io for generating short videos from prompts and keyframes

Flux3Max.io is an independent video generation website that says it uses the FLUX 3 Max model. The publisher's page explicitly says the service is unaffiliated with Black Forest Labs and fal. Its plans and credit balance belong to this website.

How to start a clip

The editor accepts a text description, a still image or multiple images set as keyframes. In image-to-video mode, the publisher describes starting from a photo with an optional last frame. A starting image can set the look of a shot; keyframes give the editor more points in time to work toward.

The service describes videos between five and twenty seconds long at 720p or 1080p, with sound. Choose a length and resolution before generating so the editor can display the credit cost. The service does not advertise 4K output.

What the keyframe mode controls

The keyframe mode accepts up to ten images and lets users place each one at a chosen time. The publisher lists 24 frames per second and says the model moves through the supplied frames in order. Keyframes constrain the sequence. They do not by themselves establish what every frame between those points will look or sound like. Review a draft before paying for a longer or higher-resolution version.

Paying for generation

The pricing page lists a 720p rate of 36 credits per second and a 1080p rate of 62 credits per second. It uses one-time packs rather than a subscription. The publisher says a qualifying new account can get 180 credits by signing up with Google, which covers one five-second clip at 720p. A failed generation does not use credits, according to the service. Check My Videos after a connection timeout, since a finished file may still appear there.
