Flux 3 Max and Flux 3 Max Keyframes share the same output, 5 to 20 seconds of video at up to 1080p with sound, and differ mainly in how many fixed images you can hand them. Flux 3 Max takes a written prompt, one opening image, or an opening and a closing image. Flux 3 Max Keyframes accepts anywhere from 1 to 10 images and threads them through a single clip in the sequence you upload them. Both run in the Picsart AI Playground, so choosing between them comes down to how much of the clip you have already planned.
The short answer: count your fixed moments
Before opening either model, count the images that must appear on screen. Zero, one or two points to Flux 3 Max, while three or more points to Flux 3 Max Keyframes.
| Flux 3 Max | Flux 3 Max Keyframes | |
|---|---|---|
| Input | Written prompt, opening image, or opening and closing images | 1 to 10 images plus a prompt |
| Image placement | Beginning, or beginning and end | Evenly spaced, in upload order |
| Prompt’s job | Can describe the entire shot | Shapes camera movement, speed and atmosphere across the images |
| Length | 5 to 20 seconds, 1-second steps | 5 to 20 seconds, 1-second steps |
| Resolution | 720p or 1080p | 720p or 1080p |
| Aspect ratios | Auto, 21:9, 2:1, 16:9, 4:3, 1:1, 3:4, 9:16 | Auto, 21:9, 2:1, 16:9, 4:3, 1:1, 3:4, 9:16 |
| Audio | On by default, optional | On by default, optional |
| Reasoning level and seed | Low or high (high by default), fixed seed | Low or high, fixed seed |
How each model reads your images
Flux 3 Max treats images as anchors at the edges of a shot. With no image at all, it composes everything from the prompt. With one, the clip opens on that picture and moves forward. With two, it opens on the first and finishes on the second, working out the movement in between so the final frame is exactly the ending you chose.
Flux 3 Max Keyframes treats images as stops along a route. Upload them in the order they should play and the model distributes them at equal intervals across the clip, then generates the motion carrying each one into the next. The result is a set of stills turned into one continuous take rather than a slideshow.
What the prompt does in each
With Flux 3 Max, the prompt can carry the whole idea. Written words alone are enough for the model to build the entire shot, and adding an opening or closing image pins down where that shot starts and finishes.
With Flux 3 Max Keyframes, the images already decide what appears and when, so the prompt has a narrower and more precise job. It shapes how the camera moves, how fast the clip travels from one image to the next, and the mood holding the sequence together.
Opening image: a sealed matte black gift box on a marble counter. Closing image: the open box with a silver watch inside. The lid lifts slowly, warm side light catches the tissue paper, and the camera pushes in until the watch face settles in sharp focus. Five keyframes in order: a packed suitcase by a front door, a train window with fields rushing past, a seaside hotel balcony, a plate of grilled fish at a harbor café, and a sunset over the water. Smooth forward camera movement through each scene, warm late-summer color, gentle travel pacing, soft ambient sound of trains, waves and conversation.Flux 3 Max: bookend images for a product reveal

Where they behave the same
Everything outside images and prompts is shared. Both let you set any duration between 5 and 20 seconds, render at 720p or 1080p, and choose from eight frame shapes, including auto. Both create sound as part of the same generation and let you turn it off for a silent clip. Both include a reasoning level, low or high, plus a seed you can lock, and reusing a seed with identical inputs and settings brings back a matching take.
Choosing Flux 3 Max
Flux 3 Max suits work with a clear beginning, a clear end, or neither:
- Product reveals that open on packaging and finish on the campaign hero shot.
- Storyboard beats that join two panels in a single uninterrupted move.
- Vertical social clips in 9:16, from 5 to 20 seconds, with sound already in place.
Choosing Flux 3 Max Keyframes
Flux 3 Max Keyframes suits clips with several moments that all have to appear:
- Mood boards turned into one moving piece that visits each reference in turn.
- Product lineups presenting each item in sequence, joined by camera movement and audio.
- Tutorials and stories where each step or beat maps to one image and shows up on time.
