A Video Tool for Public Information Videos and Resident AI Classes
Public institutions need video in two directions. One is promotion that announces policies and events; the other is hands-on material for the AI classes they run for residents. The first comes in many kinds with small budgets per piece, so commissioning a contractor every time is hard. The second is in growing demand, but choosing a tool for the classroom is tricky. HFLUX handles everything from script writing to video generation, subtitles and editing in the browser, so both jobs run from the same account.
What public institutions make with it
- Policy and programme explainers — new programme announcements, how to apply, notices of changes
- Event promotion — festivals, fairs, resident briefings, campaigns
- Local introductions — sights, local products, city brand videos
- Community and public service centre guidance — how to file requests, how to use facilities, class recruitment
- Multilingual guidance — guidance videos for foreign residents
- Social media content — short vertical videos for YouTube Shorts and Instagram Reels
Can staff make promotional videos themselves without commissioning a contractor?
Yes. Without a filming or editing crew, you describe what needs announcing in sentences, scene-by-scene scripts and video are generated, and you adjust order and length on the same screen.
Public content changes wording often. When an application period is extended or eligibility is adjusted, the video has to be made again, and with a contractor each change brings a revision request and a review period. Made in-house, it ends with editing the wording and generating again. Large flagship videos can stay with contractors while the guidance videos needed day to day are handled internally.
Can it be used in AI classes for residents?
Yes. Nothing needs to be installed and it runs straight in the browser, so it can be used on classroom PCs at community centres, public service centres, lifelong-learning centres and welfare centres without bringing in separate software.
More classes for residents now cover generative AI, but choosing the tool is where they get stuck. Editing software takes time just to learn to operate, and services whose screens are only in English raise the barrier for older participants while each person has to pay separately.
In HFLUX you describe a scene in a sentence and check the result right away, so participants learn by making rather than by operating software. It suits programmes that need a result within a short session, such as smart-device classes, resident media classes and digital classes for seniors. Ending the session by watching the participants' videos together leaves the results in hand.
| Step | What happens on screen | What you end up with |
|---|---|---|
| 1 | Look around the screen and make one short scene | A single scene |
| 2 | Pick the topic to announce and write sentences describing the scenes | Script and storyboard |
| 3 | Generate the scenes and add narration and background sound | A cut with sound |
| 4 | Adjust order and length, add subtitles and watch together | The finished video |
The number of sessions and their order are up to each programme. Generation takes some waiting depending on model and length, so overlapping the steps, writing the next sentence while waiting, keeps the time from going idle.
Can it make guidance videos for foreign residents and multicultural families?
Subtitles you make in Korean can be translated into 9 languages in the Edit tab, and the interface itself is available in 9 languages.
Generating the same guidance script again with only the language changed gives you another language version. Where many foreign residents live and request procedures or programme guidance is needed in several languages, it can be handled on the same screen without commissioning translation and dubbing separately. The interface can be set to Korean, English, Japanese, German, Portuguese, Spanish, French, Simplified Chinese or Traditional Chinese, so foreign participants in a class can practise on a screen in their own language.
Do we need an annual subscription contract?
No. HFLUX runs on prepaid credits rather than a subscription. There is no annual contract or seat commitment: you top up what you need, and a period without use costs nothing.
Public budgets are set per project with fixed spending windows. An annual subscription keeps charging after the project ends, while prepaid credits only spend what the project needs. Using separate services for image, video and speech means separate fees, payments and records for each; HFLUX keeps 41 AI models in one account. Credits stay valid for one year from the date of payment, and unused remaining credits are refundable. The conditions are in the Terms of Service.
| Pack | Price | Credits |
|---|---|---|
| Starter | $10 | 1,350 credits |
| Pro | $50 | 7,000 credits |
| Premium | $100 | 14,050 credits |
| Business | $300 | 42,300 credits |
| Studio | $500 | 70,550 credits |
| Agency | $700 | 98,800 credits |
| Enterprise | $900 | 127,050 credits |
These are the fixed US dollar prices for payments outside Korea through PayPal. The rates needed for budgeting are all published: the per-second credits for each model and the actual cost by length are on the pricing page, so you can work out at the planning stage what a number of promotional videos or class sessions will cost.
A 100 credit welcome bonus is added on your first top-up. While evaluating, the smallest pack is enough to check output quality and generation time.
Can participants each create an account to practise?
You must be 18 or older to create an account. Classes for residents are mostly attended by adults, so participants can practise on their own accounts.
This restriction is stated in the Terms of Service. Participants can sign up individually, or the institution can prepare practice accounts. Programmes that include people under 18 cannot give them personal accounts, so they follow along on the instructor's account screen: participants write the scene descriptions and the instructor runs the generation, and everyone watches the result together.
Can it be used for staff AI training?
It can serve as a hands-on tool in AI training for staff.
What sets it apart from other practice tools is that what is made in training can be used in the job as it is. Once the promotion team can make videos directly, the guidance videos each department needs from time to time are handled in-house, so training and adoption happen in one step.
What documentation is available for budget spending?
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 quotations and statements of account go through the same channel.
Because each institution asks for a different document format in its accounting, checking before payment shortens the process. For questions about documentation, use the in-service contact form or help@h-international.co.kr.
Can the videos we make be used on our official channels?
The outputs you generate are yours to use. They can be posted on official channels such as YouTube and Instagram and shown at events.
If you upload real photos or video of people to generate from, you need consent from the people shown. That applies whether or not an AI tool is involved. If you plan to post participants' work from a resident class on the institution's channels, it is worth getting consent for the scope of posting at the same time. Rights are covered in the Terms of Service and the scope of personal data processing in the Privacy Policy.
Which AI models does it use?
41 AI models across image, video and audio in a single account.
There is no need for the institution to sign up to several services and handle payment and records for each, and in a resident class, putting the same sentence into different models and comparing the results is itself practice material.
What you can use inside HFLUX
- FLOW — enter keywords, images, documents or video and it builds a video-ready FLOW with scenes, dialogue and cinematography; the SHOT board then takes you through character sheets, first and last frames per SHOT and video per SHOT
- STORY and SCENE — split a long script (txt, pdf or docx) into scenes, then break a finished script into SHOTs verbatim, dialogue and action lines untouched, and turn them into video
- Storyboard — decide how many SHOTs to split into and build a storyboard, with a single sheet to check the composition first
- Images — scene images and first and last frames for video, precision edit to change one part of a photo, layer split to separate one image into background, subject and text, combining several photos into one, and background removal
- Video and audio — image to video, videos of people speaking their lines, voice, sound effects and music, and adding sound to a video
- Editing and subtitles — cut and join on a timeline, add transitions and colour correction, and export an MP4 or an FCP7 XML to carry into Premiere Pro or DaVinci Resolve; subtitles are created from speech and can be moved into other language tracks
- 3D STUDIO — a written shot becomes a 3D scene with characters, props and camera in place, exported as a reference video or as GLB, USD or USDZ
- CANVAS — connect nodes to build an image, video and sound workflow on one canvas
- Upscaling — take a finished video to 1080p, 2K or 4K
Each feature is described on ABOUT US.
Where do the files you make end up?
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.
Things to settle while evaluating
- Budget line — whether it is booked as promotion or as class operation changes the spending procedure
- Documentation stage — at which stage a quotation is needed follows your institution's rules
- Participants' ages — if anyone is under 18 they cannot have a personal account, so the class follows the instructor's screen
- Classroom setup — a browser is all it needs, but if participants watch one screen together, check the projector or screen sharing
- Languages needed — decide which languages guidance for foreign residents needs, and they can all come from the same script
- Division of work — large flagship videos with contractors, day-to-day guidance videos in-house, which reduces the number of commissions
- Trial first — the smallest pack is enough to check output quality and generation time
Frequently asked questions
Can staff make promotional videos themselves without commissioning a contractor?
Without a filming or editing crew, you describe what needs announcing in sentences, scene-by-scene scripts and video are generated, and you adjust order and length on the same screen. When an application period is extended or eligibility changes, you edit the wording and generate again.
