Today we launched Minimax H3 Max, an AI video generation project focused on making fast iteration easier for creators.

One thing we wanted to explore is whether faster generation can change the prompting workflow itself. Instead of spending a long time trying to perfect the first prompt, creators can generate a scene, review the result, adjust the camera movement or visual direction, and quickly try another version.

We’re building around this idea with the Minimax H3 Max AI Video Generator, with a focus on text-to-video workflows, visual experimentation, and rapid creative iteration.

The project is now live: https://h3-max.com/

Next, we’re working on improving the overall generation workflow and making it easier to move from a simple idea to a usable video result.

Would love to hear how other builders think about speed vs. maximum output quality in generative AI products.

One thing I’ve been thinking about while working on Seed Audio 1.0 is how quickly an AI audio workflow becomes complicated once you move beyond simple text-to-speech.

A basic TTS tool is straightforward: type text, pick a voice, generate. But real use cases rarely stay that simple.

Someone might want multi-character dialogue, add background music that matches the mood, include ambient sound, and keep voice consistency across a longer scene. At that point the challenge isn’t just “generate better audio.” It’s making all those elements work together without forcing the user into a complicated multi-step process.

That’s the problem Seed Audio 1.0 is trying to solve.

Instead of generating voice, music, and effects separately and then mixing them, it treats the whole thing as one scene. You describe what you want — the dialogue, the emotion, the environment, the background — and it produces a fully mixed audio track in a single pass.

The interesting product question for me right now is how much control to expose.

Should advanced options (reference voices, timing control, multi-speaker settings) be visible from the start, or revealed only when someone actually needs them?

Too many controls make the first generation feel heavy. Too few, and power users feel limited.

I’m still testing where that balance should be.

For other builders working on generative tools: how do you add more capability without making the creation process feel heavier?

Today I focused on simplifying the creation flow for MiniMax H3 Video.

The challenge is that MiniMax H3 supports several ways to create — text-to-video, image-to-video, and reference-based generation — but showing every option at once can make the product feel more complicated than it needs to be.

The direction I’m testing is:

Prompt → Add references if needed → Generate

Advanced controls can come later when creators actually need more precision.

The goal is to make the first generation easy while still supporting more controlled workflows for character consistency, product shots, camera movement, and synchronized audio.

I’m also improving how the landing page communicates the main value: creating high-quality AI videos with references and synced sound without requiring a complicated production workflow.

Would love feedback on one thing: should advanced reference controls be visible from the start, or revealed only when needed?

One thing we've been thinking about while working on XMK Seedance is how quickly an AI video workflow becomes complicated once references are involved.

A text prompt is simple. You write an instruction, generate, review, and try again.

But real projects rarely stay that simple.

Someone might start with a product image, add a visual reference for lighting, another reference for camera movement, and then use an existing clip to explain the pacing they want. At that point, the challenge isn't just "generate a better video." It's making all of those inputs understandable and manageable.

That has changed the way we're thinking about the Seedance workflow.

We're experimenting with a more reference-led approach around XMK Seedance（https://www.xmk.com/seedance）, where images, video, audio, and written instructions can work together instead of forcing the user to describe everything through increasingly complicated prompts.

The interesting product question for us is what happens before generation.

Which reference controls the subject?

Which one is only there for style?

What happens when two references suggest different directions?

And how much control should we expose before the interface itself becomes another creative obstacle?

We're still learning where that balance should be.

The biggest lesson so far is that supporting more inputs doesn't automatically create a better workflow. The product also has to help people understand what each input is doing.

For other builders working on generative products: how do you add more control without making the creation process feel heavier?

Building MiniMax H3 Studio — a browser-based multimodal AI video generator (2K output, native stereo sound, image/video/audio references).

Today's lesson came from writing docs, not code: I went through our own generator UI field by field to verify what we actually support, and found the homepage FAQ claiming six aspect ratios for text-to-video when the real UI offers fewer. It had been live for weeks.

If you're writing marketing copy from your own spec sheet instead of your own product, you're going to ship claims you can't back. Fixing the FAQ first, then the blog posts that inherited the error.

We changed the default video duration in one of our recent tests.

I expected it to change the output. I didn't expect it to change the prompts people wrote.

With the shorter default, prompts were usually about one thing happening:

person turns toward the camera

car drives past the building

camera moves slowly toward the product

When we tested a longer starting duration, we started seeing prompts with more going on. Someone would describe an action, then a camera change, then something else happening near the end.

I don't have enough data to call this a pattern yet. It was noticeable enough that we started looking at some of the other defaults.

We had treated duration as an output setting. I'm less sure about that now.

We also tried putting more controls on the first screen.

The idea was simple: if the workflow supports more inputs, people should be able to see them.

It looked fine when we built it.

Using it felt a little busy.

We removed some of the controls, put them back, then tried hiding a few until after the first generation. I'm still not sure which version I prefer.

The same issue showed up again when setting up a MiniMax H3 test. There were several kinds of reference input we could make available, but putting every option in front of someone immediately didn't seem especially helpful.

Right now the first step is closer to:

prompt
optional image
generate

Then the other controls become available when they're useful.

This has a downside.

If I already know that I want to work with a specific reference, I don't want the interface making me hunt for it. We've already had a couple of moments internally where the "simpler" version felt slower because we knew exactly which control we wanted.

So we may change it again.

One thing I'm watching now is what people do immediately after the first result.

Do they change the prompt?

Change duration?

Add another reference?

Generate again without touching anything?

That seems more useful than arguing about which version of the first screen looks cleaner.

We're leaving the lighter version in place for now. I want to see which controls people actually go looking for before we move them around again.

Seed Audio 1.0 is a next-generation AI audio generation model that creates broadcast-ready audio from a single prompt.

With its multimodal inputs, multi-character dialogue, and production-ready output, it offers a comprehensive solution for modern AI audio creation.

Over the last few weeks, we've spent less time building new features and more time observing how people actually use AI video tools.

One pattern kept showing up.

Most users weren't asking for dozens of editing options. They wanted to get from an idea to a usable video as quickly as possible.

That changed how we thought about the product.

Instead of asking, "What feature should we add next?" we started asking, "What's slowing someone down before they even export their first video?"

We've been simplifying the workflow, reducing unnecessary steps, and making it easier to start with either a text prompt or a reference image. The goal isn't to replace professional editing software—it's to help people create a strong first draft much faster.

We're also paying attention to where people get stuck. Prompt writing, choosing a visual style, and deciding when a video is "good enough" are often bigger challenges than rendering the video itself.

This has led us to spend more time improving the overall creation workflow instead of continuously adding new buttons and settings.

We're building Seedance 2.5, and this is the direction we're currently exploring:

• Faster idea-to-video workflow
• Simpler prompt-based creation
• Better support for visual experimentation
• Less time spent on repetitive editing

I'd love to hear from other builders.

If you're building an AI product, what's one feature you removed—or decided not to build—that actually made your product better?
