As more people want to learn how to make video with AI, more courses teach it. Choosing the tool for the course is where they get stuck: editing software takes time just to learn to operate, and services from abroad bring payment and language problems for each student. In HFLUX you describe a scene in a sentence and it carries through to script, storyboard, video and subtitles, so students learn by making rather than by operating software. Nothing needs to be installed and it runs in the browser.
You put in a script, it is split into scenes and each scene becomes video, so results come out without teaching an editing timeline.
The focus moves from filming technique to planning and wording. Making a few videos through to the end while preparing the course helps: each model does better with different subjects and the same sentence can give varying results, so knowing in advance where students get stuck makes the class run smoothly.
No. HFLUX runs on prepaid credits rather than a subscription. Only what you actually generate is deducted from your credits, and a period without classes costs nothing.
Using separate services for image generation, video generation and speech synthesis means a fee for each that keeps running in months without students, with payment and records handled separately for each, and when the screen is only in English students get stuck on operating it first. HFLUX keeps 41 AI models in one account. Credits stay valid for one year from the date of payment, so they can be kept for the next cohort, and the refund conditions for unused credits are in the Terms of Service.

These are the fixed US dollar prices for payments outside Korea through PayPal.
A 100 credit welcome bonus is added on your first top-up. While deciding whether to use it in a course, the smallest pack is enough for a trial production.
The interface itself is available in 9 languages, and subtitles you make can be translated into 9 languages in the Edit tab.
The interface can be set to Korean, English, Japanese, German, Portuguese, Spanish, French, Simplified Chinese or Traditional Chinese, so international students can practise on a screen in their own language, which cuts the time spent explaining an English-only interface. On the generation side, even if you type in Korean, narration, subtitles and titles can be produced in the language you choose, so a language school can make several language versions of the same script.
You must be 18 or older to create an account. Adult students can practise on their own accounts.
This restriction is stated in the Terms of Service. In adult classes you can choose between students topping up individually and preparing practice accounts. Students under 18 cannot have personal accounts, so the class follows along on the instructor's account screen: students write the scene descriptions and the instructor runs the generation, and everyone watches the result together. Groups writing different sentences and comparing the results gives more to discuss.
| Step | What happens on screen | What you end up with |
|---|---|---|
| 1 | Look around the screen and generate one short scene | A single scene |
| 2 | Regenerate while changing the sentence that describes the scene, and compare | Comparison cuts |
| 3 | Pick a topic, put in a script and split it into scenes | Script and storyboard |
| 4 | Generate each scene and keep consecutive scenes consistent | A set of scenes |
| 5 | Add narration and background sound | A cut with sound |
| 6 | Adjust order and length on the edit screen and add subtitles | A rough cut |
| 7 | Rebuild it as a short vertical video | A vertical version |
| 8 | Watch the finished videos together | The finished video |
The number of sessions and their order depend on the students and class time. Classes that need a slower pace can spend longer on the early steps and drop step 7.
Credits are deducted only for what is generated, so the cost follows how many scenes each person generates at a time.
Making one video through to the end as a trial and checking the credits deducted gives you a baseline. What drives cost is the number of regenerations more than the number of scenes. Regenerating until satisfied widens the spread, so a common approach is to set a cap on generations and refine the wording within it.
The per-second credits for each model and the actual cost by length are all published on the pricing page. Even without a trial you can work out a whole cohort's budget from the number of students and sessions, and compare how much the cost changes with the model you have students use.
Payments outside Korea are processed through PayPal at fixed US dollar prices. Won payments in Korea can be processed with a Korean tax invoice, and cash receipts and quotations go through the same channel.
The documents needed depend on how you book the expense, so deciding the account first makes settlement simpler. For questions about documentation, use the in-service contact form or help@h-international.co.kr.
Yes. The account you teach with can make recruitment videos and short vertical videos as well.
Make 9:16 vertical video with the Shorts · vertical preset on the node canvas or in the Video tab, add subtitles in the Edit tab, and it is ready for Instagram Reels or YouTube Shorts. Making the video that announces a new class with the tool that class will use lets you show the result directly when people ask about the course.
Each feature is described on ABOUT US.
Outputs are kept in company storage for up to 7 days and then deleted automatically, and they are deleted immediately if you close your account.
For image outputs and speech synthesis outputs, only one representative file per generation is kept for the same period; the rest are not stored on the Company's servers and are saved only on your own PC (locally). With background removal the original never leaves your machine, and subtitles generated in the browser keep the audio on your machine. Retention is not guaranteed, so save the original to your PC as soon as you generate it. The details are in the Privacy Policy.
Can I teach AI video production without a video background?
You put in a script, it is split into scenes and each scene becomes video, so results come out without teaching an editing timeline. The focus moves from filming technique to planning and wording. Making a few videos through to the end while preparing the course shows you the generation time and how much results vary.
