FLUX 3 Max vs Boreal: Price, Audio and Which to Use

FLUX 3 Max vs Boreal is mostly a price question. On VIDEO AI ME, Boreal costs 1 credit per second at 720p and 3 at 1080p, adds a 2K tier and accepts your own audio track. FLUX 3 Max costs 17 credits per second at 720p and 29 at 1080p. Both run 5 to 20 seconds with sound.

On paper, Boreal leads this pairing on price, top resolution and audio input. The case for FLUX 3 Max rests on what its developers claim for it, stronger prompt adherence and better visual quality, and on whether those claims hold up on your brief. This comparison lays the numbers out plainly, gives Boreal its due, and shows you how to decide with your own clips rather than a spec sheet.

FLUX 3 Max vs Boreal: how do the specs compare?

Two rows match: clip length, and the 720p and 1080p tiers. The rest favours Boreal on paper, with a 2K tier and the option to supply your own audio track instead of generated sound.

For planning on FLUX 3 Max, the editor offers 5, 8, 10, 12, 15 and 20 second durations, generated in one pass with no stitching, and aspect ratios of auto, 9:16, 16:9, 1:1, 4:3, 3:4 and 21:9. Auto renders 16:9 for text to video and follows your image for image to video. Every clip comes back with sound generated in the same pass: ambience, effects, music, and the spoken lines you write into the prompt.

Which is cheaper, FLUX 3 Max or Boreal?

Boreal, by a wide margin. At 720p, Boreal costs 1 credit per second against 17 credits per second for FLUX 3 Max, so one second of FLUX 3 Max buys seventeen seconds of Boreal. At 1080p the rates are 3 against 29. One credit is one cent of generation cost.

Even Boreal at its top tier, 12 credits per second, costs less than FLUX 3 Max at 720p.

Here is what each monthly plan covers in ten second clips:

The plans are on the VIDEO AI ME pricing page, and the FLUX 3 Max pricing breakdown covers every duration and resolution.

Can rerolls close the price gap between FLUX 3 Max and Boreal?

Not on their own, and it is worth being clear about that. At 720p and ten seconds, one FLUX 3 Max take costs 170 credits, which pays for seventeen Boreal takes. If Boreal needed five takes to land a brief that FLUX 3 Max landed in one, Boreal would still cost 50 credits against 170.

So the argument for FLUX 3 Max here is not cost per clip. It is time and fit. Every take somebody has to watch with sound on is review time, and on a campaign that matters, the scarce resource is often the reviewer, not the credits. The question to answer with your own clips is whether a brief needs what the developers say FLUX 3 Max is tuned for.

What do its developers claim for FLUX 3 Max?

FLUX 3 Max is a post-trained variant of Black Forest Labs' FLUX 3 Video, which its developers describe as tuned for stronger prompt adherence and better visual quality, and optimized for lower latency. Those are the developers' claims, not measurements, so treat them as the things your test should check.

FLUX 3 Max also reasons about your prompt and expands it before rendering, so a short prompt still produces a full shot. The other side of that is that anything you leave open gets filled in for you. If the product colour, the framing or the exact line matters, write it down. The FLUX 3 Max review sets out the full list of strengths on paper and the limits.

When should you pick Boreal over FLUX 3 Max?

For a lot of everyday ad production, Boreal is the sensible default in this pair.

When you are testing angles at volume. At 10 credits for a ten second 720p draft, you can test a wide spread of hooks, settings and lines for less than one FLUX 3 Max take. Most test clips never run, so the cheapest take that answers the question is the right one.

When you already have the voiceover. Boreal takes an uploaded audio track, so a recorded voiceover, a client-approved script read or a licensed soundtrack can drive the clip. FLUX 3 Max does not accept an audio upload or lip sync to your own track. You can replace the track on a FLUX 3 Max clip with your own audio afterwards, but a presenter's mouth was generated for the model's own audio, not yours.

When the deliverable is larger than 1080p. Boreal renders 2K at 12 credits per second, and FLUX 3 Max stops at 1080p.

When you are animating a product catalogue. One product image per clip, a short motion prompt, and a price per take low enough to cover a whole range on one plan.

When should you pick FLUX 3 Max over Boreal?

When your side by side test says so. If FLUX 3 Max produces fewer rejected takes on your product, your action and your line, the time saved in review can be worth more than the credit difference on a hero clip.

When missed details are your bottleneck. If the takes you reject on any model tend to fail on specifics, such as the wrong product colour, the wrong action or a paraphrased line, those are exactly the things its developers say FLUX 3 Max is tuned for. That makes it the right model to test against.

When a clip will carry real media spend. For an ad that will run for weeks, one more take on a second model is a small cost next to the budget behind it. Different models interpret the same prompt differently, and a second interpretation of a winning prompt is useful information.

How do you test FLUX 3 Max against Boreal yourself?

1. Take a brief you really need: 10 seconds, 9:16, text to video.
2. Write one prompt in plain language and use the same text on both: subject and action, camera, light and look, then sound.
3. Run three takes on Boreal at 720p (30 credits) and one take on FLUX 3 Max at 720p (170 credits).
4. Score every take on the same four checks. Is the product right? Is the action what you wrote? Is the line spoken word for word? Does the sound sit on the action?
5. Count usable takes and the time you spent reviewing. Then decide which model gets the 1080p render.

A prompt for the test:

A woman in her thirties pours oat milk from a carton into an iced coffee on a cafe table, stirs once and looks up at the camera with a small grin. Handheld, eye level, gentle push-in. Bright midday light from a street window on the left, warm natural grade. She says, "Okay, this is my new order." Cafe chatter in the background, ice clinking in the glass, the scrape of the spoon, no music.

Ten seconds holds about 20 to 25 spoken words, so write fewer than you think. The guide to FLUX 3 Max sound and dialogue prompts covers how to write the sound line. On both models, watch the generated speech and lip sync before a clip goes live. Keep on-screen text and logos out of the prompt as well: small text and exact logos inside generated frames are unreliable on every video model, so add them after export, in your own editing tool.

What does a workflow that uses both look like?

Credits come from the same plan whichever model you pick, so the practical answer is usually both, in sequence.

1. Concept on Boreal at 720p. Six angles, 10 seconds each: 60 credits.
2. Refine the two winners on Boreal. Two more takes each with tighter prompts: 40 credits.
3. Render the best prompt on both at 1080p. 30 credits on Boreal, 290 on FLUX 3 Max.
4. Keep the clip that scores better. If it needs your own voiceover, it stays on Boreal.

That is 420 credits from first idea to a final with a second opinion, and most of the spend is the single FLUX 3 Max render. Before you lock durations, check the placement specs on TikTok for Business and Meta for Business, and the YouTube Help guide to video ad formats if the clip is headed for YouTube.

Frequently Asked Questions

What is Boreal AI video?

Boreal is a video model in the VIDEO AI ME picker. It does text to video and image to video, renders 720p, 1080p or 2K, generates clips of 5 to 20 seconds with sound, and can take your own audio track. It costs 1, 3 or 12 credits per second depending on resolution.

Can FLUX 3 Max use my own voiceover?

No. FLUX 3 Max on VIDEO AI ME always generates its own audio and does not accept an uploaded track or lip sync to one. You can replace the track with your own audio afterwards, but a presenter's mouth follows the generated audio. For your own voiceover, use Boreal.

Both generate 5 to 20 seconds in one pass on VIDEO AI ME. FLUX 3 Max offers 5, 8, 10, 12, 15 and 20 seconds in the editor. For a longer piece, generate separate scenes on either model and join them in the editor.

Which is better for testing ad creative?

On cost, Boreal. At 1 credit per second at 720p, a ten second draft costs 10 credits, so you can test many angles for the price of one FLUX 3 Max take. Use FLUX 3 Max as a second opinion on the prompts that win, and keep whichever clip scores better.
