Multilingual scenes
How many languages can share one scene?
Five, and it doesn't fall apart — coverage actually improves as the count climbs, because the model answers more speakers by cutting to more of them.
What we ran
Thirty-two takes, all delivered, all 21:9 at 1440×608. Two bins.
The top strip is eight one-person code-switches, 10 to 15 seconds, on very short prompts — 131 to 232 characters. A woman ordering in Cantonese then turning to a friend in English. A sushi master teaching in Japanese to an apprentice who answers in English. A Hong Kong director giving notes mid-sentence: 「呢個 take 好啲,but I need more rain, 再嚟一次,action!」
The grid below is twenty-four whole rooms, all 15 seconds, on 680 to 1,003-character prompts written as scripts with speaker labels. Six at two languages, six at three, six at four, six at five. A Rotterdam housing office in Dutch, English, Turkish and Arabic. A Dubai site canteen in English, Hindi, Bengali, Nepali and Tagalog. A Paris transfer desk running French, Arabic, English, Portuguese and Russian through one agent.
The board asks three things: does each face match the language coming out of it, do the accents stay distinct, does it fall apart as the count climbs.
State the limit first. We read frames and cut structure, not a transcript — there is no audio-language check in this pass. What we can settle is staging, casting, coverage, and every character of text burned into the picture. The third question we can answer properly. The first two we can only answer for the takes that put their language on screen.
What happened
It does not fall apart. It gets busier. Cuts per take rise with the language count: 3.5 average at two languages, 4.2 at three, 4.0 at four, 7.3 at five. The obvious failure mode — collapsing into one static ensemble wide because there are too many people to cover — is not what happens. 32 Press line runs fifteen cuts in fifteen seconds, roughly one per second, because the brief gives five journalists one question each and the model cuts to each of them. 30 Transfer desk runs eight. The model reads "five speakers" as "five setups."
1A karaoke duet: she sings the Cantonese verse of a 90s ballad, he answers with an English verse, both sets of lyrics highlighting on the screen behind them in their own scripts.One take does collapse. 29 Site canteen, Dubai holds a single wide for the full fifteen seconds with two reframes, seats six men where the script wrote five, and never plays the beat the scene is built on — B checking the time and standing up. It is the exception, and it is the only one.
1A construction site canteen in Dubai at the end of a shift. Five men at one long table, arguing about a goal.2A (English): "The second goal was offside. It was clearly offside."3B (Hindi): "अरे नहीं यार, वो गोल कमाल का था।"4C (Bengali): "গোলটা ভালো ছিল, কিন্তু গোলকিপারের দোষ।"5D (Nepali): "गोलकिपरको गल्ती होइन! डिफेन्सको हो!"6E (Tagalog): "Depensa talaga. Palagi na lang depensa."7They are shouting over each other and enjoying it enormously. Then B checks the time and stands up, and the table goes quiet.8A: "What time's your flight?"9B (Hindi, picking up his tray): "चार बजे।"10Three years. Nobody says it. Instead:11C (Bengali, loudly, sitting back): "যাই হোক — গোলকিপারের দোষ।"12D: "होइन भन्या!"13And the argument starts again, louder than before, and B sits back down with his tray.14Plastic trays, strip lighting, a small wall-mounted TV. The story: they keep arguing because it is the only way any of them can say goodbye.
The small emotional beats survive the crowd, which is the surprise. These scripts hide their meaning in one physical action, and the action comes back. 24 Housing office, Rotterdam: the caseworker's coat is over the back of her chair in the first frame exactly as written, the woman arrives out of breath holding a blue folder, and the caseworker sits back down and puts the coat over her knees. All three beats, in order, in fifteen seconds, across four languages. 26 Ferry office, Athens does the same — the clerk "closes her window, comes out from behind the glass, and takes the woman's bag," and she does, with the queue watching. 28 Parents' evening, Berlin cuts to a close insert of a pen being set down on the page, which is the entire point of the scene.
1A ferry ticket office at Piraeus in the morning rush. A queue, a clerk behind glass, a delay.2CLERK (Greek, to a colleague): "Το οκτώ έχει καθυστέρηση."3TOURIST (English): "Is the eight o'clock delayed?"4CLERK: "Forty minutes. Sorry."5ALBANIAN TRAVELLER: "Kur niset anija tjetër?"6CLERK: "Në dhjetë."7RUSSIAN TRAVELLER: "Один билет, пожалуйста."8CLERK: "Двенадцать евро."9At the back, an elderly woman has been standing very still for some time, holding a ticket. The clerk notices the ticket's colour.10CLERK (Greek, standing up): "Κυρία μου — αυτό ήταν χθες."11OLD WOMAN: "Ναι."12CLERK: "Χθες το ακύρωσαν. Δεν σας το είπε κανείς;"13OLD WOMAN: "Όχι."14The clerk closes her window, comes out from behind the glass, and takes the woman's bag. The queue watches and nobody complains.15Scuffed counter, harbour light. The story: someone has been waiting a whole day for a boat that was cancelled.
Burned-in text is clean in every script we could check. 2 renders the sushi master's Japanese as "Don't squeeze the rice too tightly. / Don't kill the fish." and the apprentice's English as "Not too tight. Got it." 6 puts up the Mandarin lower-third 台风今晚登陆,请市民留在室内 — correct characters, exactly as prompted — then, when the anchor turns to camera two, replaces it with "TYPHOON TO MAKE LANDFALL TONIGHT / RESIDENTS URGED TO STAY INDOORS." The prompt asked for "the lower-third switches scripts with her." It does.
7 is the best of them. The prompt asks for a karaoke duet with "both sets of lyrics highlighting on the screen behind them in their own scripts." The screen shows 夜雨輕輕落下 / 我仍等你回來 in traditional characters with a yellow highlight wipe that actually tracks her singing, and when the man joins, a second English line appears underneath in the same yellow.
Text written inside the scene is a different system, and it fails. 20 Study group, Sydney opens on an overhead insert of a notebook — the maths on the page is mirror-written, reversed left to right. 31 Trade fair, Hong Kong has a booth sign in the background whose Chinese characters are flipped into nonsense. 32 has a journalist writing illegible scribble. Subtitles and broadcast graphics are composited correctly; anything the camera has to look at as an object in the world comes back backwards. If a note, a sign or a whiteboard carries plot, do not let the model write it.
1A university library in Sydney, close to midnight. Three postgrads at one table.2A (Korean, muttering at her own page): "이거 왜 이렇게 안 풀리지…"3B and C exchange a very brief look and say nothing.4She works. Two full seconds of nothing but pen on paper. Then her hand stops.5A: "…아. 부호."6She fixes one sign and the whole thing collapses into place.7A (English, suspicious): "How long have you two had this?"8B (English): "Had what?"9C (Mandarin, not looking up): "我们什么都没说。"10A: "You've had it for an hour."11B: "Forty minutes."12A: "…진짜 너무하네."13She is laughing. C pushes a coffee across to her without comment.14Desk lamps, laptops, empty cups. The story: two friends let her get there herself.
The one-person strip is cheap and it lands. Eight takes at 131–232 characters — a fraction of the room prompts — and every one returned the staging it asked for. 8 HK director puts him under an umbrella on a wet lit street with the crew around him, and cuts to a wide of the rain towers running down the whole set, which is the "the crew responds instantly" beat. 5 French narrator over an American diner delivers the exact prescribed image: a trucker salting his fries at 2am, the scene entirely indifferent to the voice over it. Two speakers, one scene, short prompt — that combination is the reliable one.
Casting matches the language on the page where the language is visible. 27 Emergency room walks the nurse down four patients in four setups, and the patient scripted 肚子疼 is visibly holding his stomach. 13 Bakery, Marseille puts the mother in a headscarf, the son at the dough, oven light warm against blue pre-dawn through the window, and cuts to the macro of his hands slowing on their own — the beat the whole scene turns on.
Notable takes
26 | 4 langs · Ferry office, Athens | Greek, English, Albanian and Russian through one window, then the clerk comes out from behind the glass for the woman with yesterday's ticket — the scripted ending, delivered whole.
24 | 4 langs · Housing office, Rotterdam | The coat over the chair, the coat over the knees. Three physical beats in order in fifteen seconds, and the language count never gets in the way.
1A municipal housing office in Rotterdam, four minutes before closing. The caseworker has her coat over the back of her chair.2CASEWORKER (Dutch): "Meneer de Vries, uw formulier is compleet. Tot ziens."3She reaches for the coat. The door opens. A woman comes in fast, holding a folder, out of breath, clearly expecting to be turned away.4CASEWORKER (English, automatically): "We close at five."5WOMAN: "I know. I'm sorry. The bus—"6The caseworker looks at her for a moment. Then she sits back down and puts the coat over her knees instead.7CASEWORKER: "Kom maar."8The woman doesn't move, not sure she has understood.9CASEWORKER (switching, gently): "تفضلي. اجلسي."10The woman's shoulders drop about two inches. She sits.11CASEWORKER: "Nu. Laat maar zien."12Strip lighting, numbered tickets, plastic chairs. The story: someone chooses to be four minutes late home.
7 | E14-025 · code-switching | Cantonese lyrics with a working karaoke highlight wipe, English lyrics underneath, both scripts on screen at once and both spelled right.
28 | 5 langs · Parents' evening, Berlin | Five sets of parents, one teacher, and the take cuts to a pen going down on the page — the model found the shot the script was aiming at.
1A Berlin primary school parents' evening. One teacher, a small table, five sets of parents.2TEACHER (German): "Ihre Tochter liest sehr gut. Wirklich sehr gut."3TURKISH FATHER: "Çok teşekkür ederim. Evde de okuyor."4ARABIC-SPEAKING MOTHER: "هل يحتاج إلى مساعدة في الرياضيات؟"5TEACHER: "Ein bisschen. Nicht viel."6RUSSIAN MOTHER: "А по-немецки он говорит хорошо?"7TEACHER: "Sehr gut. Besser als er denkt."8The last father sits down. He does not ask about reading, or maths, or German.9FATHER (English): "Is she happy here?"10The teacher stops. She puts down her pen. It is nearly nine o'clock and this is the first time all evening anyone has asked.11TEACHER: "…Ja. Sie ist glücklich."12FATHER: "Good. That's all I wanted."13He stands and shakes her hand. She stays sitting for a moment after he has gone.14Small chairs, children's paintings, evening light. The story: one parent asks the only question that matters.
20 | 3 langs · Study group, Sydney | Good coverage, real staging, and an opening insert of a notebook written in mirror image. The clearest demonstration of where in-frame text breaks.
29 | 5 langs · Site canteen, Dubai | The one that flattens: one wide, six men where the script wrote five, and the beat that carries the scene never happens.
What this means if you're prompting FLUX.3
Five languages in fifteen seconds is not the limit. The limit is how many lines you stuff in. 30 scripts ten lines in fifteen seconds and gets eight cuts to fit them, which is one setup every 1.9 seconds. Write four to six lines for a fifteen-second room and you get room to act.
Write it as a script — speaker label, colon, line, in the language it's spoken in. Every take in the room bin uses that format, and the staging comes back matching it. Put the language in parentheses after the speaker label when the language isn't obvious from the script itself.
Give the scene one physical action that carries the meaning. A coat moved from a chair to a knee. A pen put down. A window closed and walked around. Those are the things that survive four other people talking, and they are what makes the take read as a scene rather than a demo.
Subtitles: ask for them, and trust them. Signs, notebooks, whiteboards: don't. If it's written on paper in the world of the shot, it will come back mirrored, and you'll be compositing it yourself.
Two languages in one mouth is the cheapest good result in the family. Eight takes averaging 186 characters, all of them usable. Scale the prompt only when you scale the room.
Every take above is straight out of the model — nothing cut, graded or retouched — and every prompt is printed in full.
