FLUX 3 Max Cinematic Video: 21:9 Brand Films at 1080p

To make a cinematic brand video with FLUX 3 Max, choose 21:9 at 1080p, write each shot as one continuous take of up to 20 seconds with a single camera move, and direct the sound as carefully as the picture. A 20 second 1080p shot costs 580 credits, so a three-shot brand film comes to about 1,600 credits.

This guide covers FLUX 3 Max cinematic video from the frame out: what actually makes footage read as cinematic, why 21:9 and 1080p, how to write a 20 second single shot, the camera language that works in a prompt, sound design, a cost table per shot, and where a widescreen film should run.

What makes a video look cinematic?

Resolution alone does not do it: a 1080p clip shot like a phone video still looks like a phone video. The cinematic read comes from deliberate choices, each of which can be written into a prompt:

Why shoot a FLUX 3 Max brand film at 21:9 and 1080p?

21:9 works out to about 2.33:1, close to the wide frame many feature films use, which is why it reads as cinema before anything moves. The VIDEO AI ME editor offers 21:9 as a named ratio for FLUX 3 Max, at 720p or 1080p. Choose it explicitly: on auto, text to video renders 16:9.

1080p is the top resolution FLUX 3 Max renders, and the per-second price is what makes it practical for brand work. Here is how it sits against the other models in the editor that are relevant to this job:

At 29 credits per second, 1080p FLUX 3 Max costs less per second than Seedance 2.5 at 720p (48). Each model fits a different job: Seedance 2.5 runs longer clips and takes reference videos, Happy Horse 1.1 is the lower-cost 1080p option at up to 15 seconds, and Boreal is the choice if you need 2K or want to bring your own soundtrack. FLUX 3 Max is the fit when you want a 20 second widescreen take at 1080p with sound generated in the same pass.

How do you write a 20 second single shot?

A 20 second take needs one beat with a shape: where the camera starts, what happens, where it ends. It is room for one beat done well, not a montage. Three scenes means three clips, joined in the editor.

Write one paragraph in this order: subject and action, then camera, then light and look, then sound. Opening shot, text to video, 21:9, 20 seconds:

A lone hiker in a dark green wool jacket walks along a narrow mountain ridge at dawn, stops at the edge, and pulls her hood back as the wind catches her hair. Slow aerial-style push-in from a wide establishing shot, ending on a medium shot over her shoulder as the valley opens below. First sun breaking over the far peaks, cool blue shadows and warm gold highlights, soft film grain, shallow depth of field at the end of the move. Wind gusting from the left, gravel crunching under her boots as she stops, a distant bird call, a low sustained cello note that swells as the sun appears.

One move with a start and an end, one turn in the action, light with a source, and sound tied to the action.

For a product hero, use image to video. Compose or crop your start image to a wide frame first, so the first frame is not a forced fit, then set the ratio to 21:9. The image already carries the look, so the prompt is about motion and sound. Product shot, image to video, 21:9, 15 seconds:

The camera makes a slow half-orbit around the watch as a sliver of morning light moves across the dial and the second hand sweeps. Dew on the stone catches the light as the move ends. A soft mechanical tick, quiet wind, a single low piano note, no voice.

Keep the move small: the further the camera travels, the more of the product the model has to invent beyond your photo.

A brand film often closes on a line. Spoken lines go in double quotes with who says them, and at cinematic pace you want far fewer words than the clip could hold. A 20 second shot could carry 40 or more words; for a closing voiceover, 10 to 15 feels deliberate:

A fishing boat leaves a small harbour at first light and moves slowly out across flat grey water. Locked-off wide shot from the harbour wall, no camera movement. Pale overcast dawn, desaturated cool grade, soft film grain. A man's voice, low and unhurried, says, "Some things are worth getting up early for." Gulls overhead, water lapping against the wall, a diesel engine fading into the distance, no music.

The brand name and logo go on an end card you add after export, in your own editing tool, never in the prompt, because exact logos and small text inside generated frames are unreliable on every video model. Watch the generated speech and lip sync on every clip with a line before it goes live.

Which camera moves read as cinematic in a FLUX 3 Max prompt?

Name one move per shot and say where it starts and ends. Stacking moves gives the model competing instructions for one take.

Look words such as "anamorphic-style lens flare", "film grain" and "shallow depth of field" are worth trying; check how each renders in a 720p draft before you build a film on it. The full move library is in the FLUX 3 Max camera movement prompts guide.

How do you design sound for a FLUX 3 Max cinematic video?

FLUX 3 Max always generates audio in the same pass as the picture: ambience, effects, music and any spoken lines, so the sound sentence is part of the direction. Four habits:

• Write the order. Spoken lines first, then ambience and effects, then music or "no music".
• Place the sound. "Wind from the left, a river on the right" builds a space wider than the frame, which suits 21:9.
• Tie sound to action. "Gravel crunching under her boots as she stops" lands the sound on the beat.
• Describe music by instrument and shape. "A low sustained cello note that swells as the sun appears" gives a direction; "epic music" leaves the choice to the model.

Write the ambience even when it feels obvious, or the model decides for you. For a film cut from several clips, decide on music once: each generation brings its own score, so music written into every clip can sound like three different films. One approach is a scored opening and "no music" for the rest. If a clip's audio does not fit, replace the track with your own audio.

Google's ABCDs of effective video ads recommend mentioning the brand in audio, not only on screen. For a brand film that means the closing voiceover can name the brand, with the logo end card added after export.

What does a FLUX 3 Max cinematic video cost?

FLUX 3 Max costs 17 credits per second at 720p and 29 credits per second at 1080p, the same for text to video and image to video. A three-shot brand film:

Drafting all three at 720p and then rendering at 1080p comes to 2,530 credits. The Pro plan at 5,600 monthly credits covers two full films with drafts. On the Starter plan's 1,400 monthly credits, a two-shot film fits: the opening and the product hero at 1080p (1,015 credits) plus one 720p draft of the opener (340), 1,355 credits in all. Native 16:9 and 9:16 cutdowns of the closing shot, 15 seconds each, add 870 credits at 1080p.

For context, the same 55 seconds at 720p on Seedance 2.5 would cost 2,640 credits. One credit is one cent of generation cost, so the 1080p film above is $15.95 of plan credit. Every duration is worked out in the FLUX 3 Max pricing guide, and current plans are on the pricing page.

Frequently Asked Questions

What makes AI video look cinematic?

Deliberate choices rather than resolution alone: a wide frame, one motivated camera move per shot, held takes, light with a clear source, shallow depth of field and designed sound. With FLUX 3 Max, each of those is a sentence in the prompt, plus the 21:9 ratio setting.

What aspect ratio is best for a cinematic video?

21:9 is the closest widescreen option to the wide frame many feature films use, and FLUX 3 Max offers it in the editor at 720p and 1080p. Use it where the player adapts to the video, such as your YouTube channel or website, and cut native 16:9 or 9:16 versions for ad slots.

Is 1080p good enough for a brand film?

1080p is the top resolution FLUX 3 Max renders, and YouTube Help lists 1080p as an HD resolution for uploads. If a project needs a resolution above 1080p, Boreal renders 2K on VIDEO AI ME.

How long can a single FLUX 3 Max shot be?

Up to 20 seconds in one generation, with no stitching. The editor offers 5, 8, 10, 12, 15 and 20 second durations. A longer brand film is several shots, each written as its own scene and joined in the editor.

How do you add music to a cinematic AI video?

Describe it in the sound sentence of the prompt by instrument and shape, such as a low cello note that swells as the sun appears. For a film built from several clips, write "no music" in most shots so each clip does not bring its own score, and replace a clip's track with your own audio when it does not fit.

How much does a cinematic brand video cost with FLUX 3 Max?

At the standard rate, a 20 second 21:9 shot costs 580 credits at 1080p and 340 at 720p. A three-shot, 55 second film costs 1,595 credits at 1080p, or 2,530 with a 720p draft of every shot first.
