# HERACLITUS — PEXO PRODUCTION SCRIPT ### Reformatted for Pexo.ai | 16:9 YouTube | 8 segments, 44 scenes | ~6:30 target runtime --- ## READ THIS FIRST — THE ONE STRUCTURAL PROBLEM Pexo generates video using Sora 2, Kling, Seedance and Veo. That is excellent for product ads and atmospheric storytelling. It is **actively dangerous for this particular video**, because this is a documentary about real events, a real vessel, and real living people. If you let Pexo generate "1974 volunteers building a concrete ship in Oakland," it will produce convincing footage of an event that never looked like that, featuring people who never existed. Do that, and you have fabricated archival footage of a real nonprofit's history. Same problem, worse, for any shot of Terence McKenna, Wade Davis, or John Allen — real named individuals, two of them still alive. Audiences are unforgiving about this now, and YouTube's upload flow requires you to disclose realistic synthetic content. A history channel that gets caught faking archival material does not recover. **So the build rule for this project is:** > Anything specific and factual — the ship, the people, the drydock, the places — uses a real licensed photograph, animated by Pexo (image-to-video, subtle push/parallax). > Pexo generates original video **only** for abstract, atmospheric, and non-claim-making shots: open ocean, ice, water texture, rope, concrete, starfields, weather. Every scene below is tagged accordingly. If you follow the tags, you get a video that looks cinematic and is honest. It also costs far fewer credits, because stills-to-motion is cheaper than full generative scenes. ### Asset tag legend | Tag | Meaning | Source | |---|---|---| | **[PHOTO]** | Must be a real licensed image | The Heraclitus project (see permissions section) | | **[AI-OK]** | Safe for Pexo to generate — abstract, no real people, no specific claim | Pexo | | **[STOCK]** | Generic licensed footage is fine | Pexels / Storyblocks / Artgrid | | **[GRAPHIC]** | Map, text, or title animation | Pexo or your editor | --- ## THE BRIEF — PASTE THIS INTO PEXO FIRST > I'm making a 16:9 documentary short for YouTube about the R/V Heraclitus, a real 84-foot ship built out of ferrocement by volunteers in Oakland in 1975 that has sailed 270,000 nautical miles and is currently being rebuilt in Spain. > > Important constraints, please follow strictly: > - This is factual documentary. Do not generate any footage depicting real people, real historical events, or the actual ship. I will supply real photographs for all of those and I want them animated with subtle motion only — slow push-in, gentle parallax, no warping of faces or structures. > - Generate original video only for the abstract atmospheric shots I mark as such: ocean, ice, water surface, concrete texture, rope, night sky. > - Visual tone: 1970s documentary warmth. Muted teal and rust palette, film grain, slightly desaturated. Not glossy, not corporate, not neon. > - Voiceover: male or female, mid-range, unhurried, dry rather than dramatic. Think a nature documentary narrator who trusts the material. No hype inflection, no upward-inflected sentence endings. > - Music: sparse, low strings and drone, no percussion until the Antarctica section. It should never fight the voiceover. > - Subtitles: on, clean sans-serif, bottom third, no karaoke-style word highlighting. > > I'll give you the script segment by segment with per-scene notes. --- ## SEGMENT 1 — COLD OPEN (0:00–0:48) **Scene 1** · 6s · **[AI-OK]** *VO:* "In 1974, a group of people in Oakland, California went looking for condemned houses." *Prompt:* Slow drift across weathered, peeling wooden siding of a derelict house. Overcast daylight. Heavy film grain, muted colour. No people. **Scene 2** · 5s · **[AI-OK]** *VO:* "They weren't looking for shelter. They were looking for nails." *Prompt:* Extreme macro, rusted bent nails scattered on aged timber. Shallow focus, one slow rack focus. No hands in frame. **Scene 3** · 7s · **[PHOTO]** *VO:* "They pulled the nails and salvaged the lumber, and used it to build scaffolding. And on that scaffolding, they built a ship." *Asset:* Archival scaffolding/frame photo from the build. Slow push in. **Scene 4** · 6s · **[PHOTO]** *VO:* "Not out of wood. Not out of steel. Out of concrete." *Asset:* The rebar-and-mesh hull frame. Hold, minimal motion. Let it land. **Scene 5** · 8s · **[PHOTO]** *VO:* "None of them had ever built a boat before. Fifty years later, that concrete ship has crossed six of the world's seven oceans, sailed up the Amazon, dived under Antarctic icebergs, and carried a coral reef into the Arizona desert." *Asset:* Hero shot — ship under full junk sail, open water. Slow parallax push. **Scene 6** · 7s · **[PHOTO]** → **[GRAPHIC]** *VO:* "This is the Heraclitus. And the strangest thing about it is that it's still not finished." *Asset:* The painted eyes on the bow. Push in, then title card: **THE CONCRETE SHIP THAT SAILED THE WORLD** --- ## SEGMENT 2 — WHY WOULD ANYONE DO THIS (0:48–2:05) **Scene 7** · 7s · **[AI-OK]** *VO:* "The story starts in the desert, which is a strange place for a ship to begin." *Prompt:* High desert scrubland at golden hour, New Mexico. Wide, still, slow lateral drift. No structures, no people. **Scene 8** · 10s · **[STOCK]** *VO:* "In 1969, a former metallurgist named John Allen founded a community in New Mexico called Synergia Ranch. Out of it came the Institute of Ecotechnics — a group set on demonstrating, in practice rather than theory, that human technology could be made to fit inside the biosphere instead of grinding against it." *Note:* Generic 1970s desert-commune-era stock, or a licensed Synergia Ranch photo. **Do not generate a depiction of John Allen.** **Scene 9** · 9s · **[STOCK]** *VO:* "They started projects in a lot of biomes. A ranch in New Mexico. A rainforest project in Puerto Rico. And Allen made an argument: if you actually wanted to understand this planet, you couldn't do it from land." *Note:* Rainforest canopy, then a hard cut to open ocean. The cut does the argument. **Scene 10** · 9s · **[AI-OK]** *VO:* "Seventy-one percent of the surface is water. The oceans hold about ninety-six percent of the biosphere's water. So they'd need a ship." *Prompt:* Slow aerial rise over empty open ocean, no land, no vessels. Overcast diffuse light. **Scene 11** · 8s · **[AI-OK]** *VO:* "They had no money, no shipyard, and no experience. Which turns out to be a surprisingly workable starting position, if you're willing to be strange about it." *Prompt:* Empty industrial waterfront lot, weeds through cracked concrete, grey daylight. Static with faint handheld drift. **Scene 12** · 10s · **[STOCK]** *VO:* "Allen had once lived aboard a junk in Hong Kong harbour. Junks are slow. But they're stable in heavy seas, and the crew liked what slowness implied — a boat that moves at the speed of wind and current, rather than fighting them." *Note:* Archival Hong Kong harbour junks. Public-domain archival preferred over generation. **Scene 13** · 12s · **[AI-OK]** *VO:* "For the hull, they chose ferrocement. Concrete over steel and wire mesh. Cheap, strong, patchable at sea with materials you can buy in almost any port on Earth — and, critically for a group with more volunteers than cash, enormously labour-intensive to build with. That was the point. The material fit the people they had." *Prompt:* Macro tracking across rough grey concrete surface, embedded wire mesh visible, raking sidelight. Abstract, no context. --- ## SEGMENT 3 — THE CAFÉ THAT BUILT A SHIP (2:05–3:20) **Scene 14** · 9s · **[STOCK]** *VO:* "They moved into a three-storey redwood house in Berkeley. To fund the build, they opened a café on the corner of Telegraph and Alcatraz. They called it the Junkman's Palace." *Note:* 1970s Berkeley street archival. **Do not generate a fake storefront** — the café was real and specific. **Scene 15** · 8s · **[AI-OK]** *VO:* "It became a genuinely popular local restaurant. And its profits covered most of the ship's operating costs. A ship that circled the world, paid for by a Berkeley café." *Prompt:* Steam rising from a coffee cup on a worn diner counter, warm tungsten light, 1970s interior. Shallow focus. No faces. **Scene 16** · 9s · **[PHOTO]** *VO:* "They squatted a site at the Fifth Avenue Marina in Oakland — not far from where Jack London had built his own boat, the Snark, seventy years earlier." *Asset:* Build site photo. Slow lateral drift. **Scene 17** · 14s · **[PHOTO]** *VO:* "The keel went down in August 1974. Then a frame of half-inch steel rebar. Then a dozen layers of wire netting stretched over it. Cement was sprayed into the mesh and troweled smooth by hand, then kept deliberately wet, curing for a full month — because concrete that dries too fast is concrete that cracks." *Asset:* Build sequence, 3–4 stills cut on the beat. This is your best archival material; give it room. **Scene 18** · 11s · **[PHOTO]** *VO:* "Alongside the construction crew was a theatre company — the Theater of All Possibilities — who performed locally during the build and also swung hammers. Crew and cast were the same people. They'd stay the same people for the next fifty years." *Asset:* Any performance still from the project's gallery. **Scene 19** · 12s · **[PHOTO]** *VO:* "On February 24th, 1975, they launched her. Eighty-four feet. Three masts. A hull of concrete. Named for Heraclitus of Ephesus, the philosopher who said you cannot step in the same river twice — because neither the river nor the person is the same." *Asset:* Launch photograph. Hold longer than feels comfortable. **Scene 20** · 4s · **[AI-OK]** *VO:* "Keep that in mind. It becomes load-bearing." *Prompt:* Slow-motion water surface, sunlight fracturing, abstract. Brief. --- ## SEGMENT 4 — WHERE IT WENT (3:20–4:40) **Scene 21** · 8s · **[GRAPHIC]** *VO:* "The first voyage was supposed to be a shakedown. It went two-thirds of the way around the world." *Note:* Animated route line begins. Build this map progressively across the whole segment — it's your continuity device. **Scene 22** · 13s · **[GRAPHIC]** + **[STOCK]** *VO:* "Down the coast, through the Panama Canal, across the Atlantic to Morocco and Marseille. Through Suez, into the Red Sea, across the Indian Ocean to Mumbai — where the crew worked with the University of Bombay following up Thor Heyerdahl's research on ancient reed-boat cultures, and helped study mercury contamination in the rivers of Maharashtra." *Note:* Map line advancing, intercut with 2–3 generic location plates. **Scene 23** · 7s · **[STOCK]** *VO:* "They also cut a deal with NOAA to collect weather data — useful precisely because the Heraclitus went places weather stations don't." *Note:* ⚠️ See fact-check appendix — verify this claim before you publish. Cut the line if you can't confirm it. **Scene 24** · 10s · **[AI-OK]** *VO:* "In 1980, on a suggestion from the legendary Harvard ethnobotanist Richard Evans Schultes, they pointed the ship at the Amazon." *Prompt:* Aerial over dense rainforest canopy with a brown river winding through. Humid haze, slow forward drift. **Scene 25** · 12s · **[PHOTO]** *VO:* "They rigged the sails as a sun cover and rain catchment and motored twenty-two hundred miles upriver into Peru. They'd had a phytochemical laboratory built into the ship so plant samples could be tested fresh, on site, rather than degrading on the journey home." *Asset:* Amazon expedition photo — the project has these. **Scene 26** · 12s · **[PHOTO]** *VO:* "At the village of Pevas, a shaman who had worked with Schultes decades earlier agreed to guide the crew into the forest. Joining them aboard: Wade Davis, Dennis McKenna, and Terence McKenna." *Asset:* 🚫 **Critical — do not generate.** Real named people. Use a licensed expedition photo, or a plain typographic card listing the names over rainforest B-roll. **Scene 27** · 9s · **[AI-OK]** *VO:* "Hundreds of plants were collected, including species new to science. The specimens went to herbaria in Peru, to the Missouri and New York Botanical Gardens, and to Kew." *Prompt:* Macro of pressed botanical specimens on aged paper, archival herbarium aesthetic. Slow pan. Generic plants only. --- ## SEGMENT 5 — ANTARCTICA (4:40–5:55) *Music: percussion enters here.* **Scene 28** · 9s · **[AI-OK]** *VO:* "Then, because apparently the Amazon wasn't enough, they insulated the entire ship and sailed it to Antarctica." *Prompt:* Hard cut from jungle green to grey Antarctic seascape. Icebergs on horizon, low flat light, cold desaturated palette. **Scene 29** · 14s · **[AI-OK]** *VO:* "On New Year's Day, 1988, provisioned for two months with a crew of fifteen, the Heraclitus rounded Cape Horn and spent ten days crossing the Drake Passage — statistically one of the worst stretches of water on the planet — in a concrete boat." *Prompt:* Violent grey ocean swell from a low angle, spray, no vessel in frame. Storm light. **Scene 30** · 14s · **[PHOTO]** *VO:* "They spent six weeks running population studies on southern humpback whales, taking skin samples with light crossbow darts reeled back on a cord, for genetic work with a researcher at the International Whaling Commission. They recorded whale song." *Asset:* Expedition photo. If unavailable, licensed humpback stock — **not generated whales.** **Scene 31** · 9s · **[AI-OK]** *VO:* "Divers went under icebergs in dry suits, twenty to thirty minutes at a time in freezing water." *Prompt:* Underwater looking up at a submerged iceberg mass, shafts of blue light. No divers in frame. **Scene 32** · 13s · **[AI-OK]** *VO:* "And at Deception Island, inside a flooded volcanic crater, they found the ruins of an old whaling station — enormous rusting tanks that had once been filled with whale blubber, rendered for lamp oil and cosmetics." *Prompt:* Derelict rusted industrial tanks on a black volcanic beach, snow patches, overcast. Desolate, static, no people. **Scene 33** · 13s · **[AI-OK]** *VO:* "Six of the crew climbed inside one of the tanks and started singing. By the account of one crew member, the acoustics turned it into something else entirely — the sound of every whale that had ever been killed there." *Prompt:* Interior of a vast rusted steel tank, single shaft of light from above, dust in air. Slow upward tilt. *Audio note:* Duck the music almost to silence. This is the emotional peak of the film. **Scene 34** · 11s · **[AI-OK]** *VO:* "Not long after they left the area, they got a radio call. An Argentinean supply ship had run aground and sunk near where they'd been working. The diesel spill devastated the bay." *Prompt:* Oil sheen spreading on cold grey water, iridescent rainbow film. Slow overhead drift. --- ## SEGMENT 6 — THE REEF IN THE DESERT (5:55–7:00) **Scene 35** · 10s · **[STOCK]** *VO:* "In 1990, the Heraclitus took on its strangest cargo. The same network of people had built something else by then — Biosphere 2, the sealed glass ecosystem in Oracle, Arizona, where eight people would spend two years living inside a miniature Earth." *Note:* Biosphere 2 is heavily photographed and still operating. Licensed stock is easy here. **Scene 36** · 6s · **[AI-OK]** *VO:* "Biosphere 2 needed an ocean. And an ocean needs a reef." *Prompt:* Healthy tropical coral reef, clear turquoise water, slow forward glide. **Scene 37** · 15s · **[PHOTO]** / **[STOCK]** *VO:* "Off Akumal in the Yucatán, the crew gathered hundreds of coral specimens, floating them to the surface on lift bags. The corals went into trailer trucks fitted with lights and pumps to hold temperature, salinity and nutrients steady, and were driven three days across the border into the Arizona desert." *Note:* Strongest visual gag in the film — reef, then desert highway. Sell the absurdity with the cut. **Scene 38** · 9s · **[STOCK]** *VO:* "They didn't just survive. Inside the sealed biosphere, eighty-seven new coral colonies formed." *Note:* Biosphere 2 ocean biome interior. **Scene 39** · 16s · **[STOCK]** + **[GRAPHIC]** *VO:* "It became the largest artificial reef ever built — and because it was sealed, every exchange with the atmosphere could be measured exactly. Which made it one of the earliest hard datasets on what rising carbon dioxide does to coral. The findings were not encouraging. The methods developed there went straight back onto the Heraclitus, which spent the next decade mapping reef health across the Indian and Pacific Oceans." --- ## SEGMENT 7 — THE COMPLICATED PART (7:00–7:45) > **Keep this.** Your comments will raise it within the hour regardless. Forty-five seconds of honesty buys the entire video its credibility. **Scene 40** · 14s · **[STOCK]** *VO:* "Now — you may already know Biosphere 2 ended badly in the press. When journalists dug into who was actually running it, they found the theatre commune. A number of them concluded the whole thing was less a scientific institution than a personality cult built around John Allen. One 1991 investigation called it exactly that." *Note:* Newspaper clipping montage. Use real archived headlines, or plain typographic treatment. **Do not generate fake newspapers** — fabricating press coverage of a real controversy is the worst possible version of this mistake. **Scene 41** · 10s · **[STOCK]** *VO:* "Former members described an authoritarian atmosphere. The 2020 documentary Spaceship Earth walks through all of it. Defenders point out that Biosphere 2 nonetheless produced real science, that it's now run by the University of Arizona, and that the Institute's projects have outlasted the controversy by three decades." **Scene 42** · 13s · **[PHOTO]** *VO:* "Both of those things can be true. A group can be genuinely strange in its internal culture and still have built a ship that sailed 270,000 nautical miles and did real work. That tension is the actual story here — and it's more interesting than either half alone." *Asset:* Return to the ship at sea. The image resolves the argument. --- ## SEGMENT 8 — ROSES, SPAIN + OUTRO (7:45–9:00) **Scene 43** · 16s · **[PHOTO]** *VO:* "Most working ships last about thirty years. The Heraclitus sailed for forty. Her last expedition documented coastal communities around the Mediterranean — nearly a hundred and fifty interviews across six countries with people whose relationship to the sea is being rewritten by ecological change. Then, in 2012, they hauled her out at Roses, on the Catalan coast, and started taking her apart." **Scene 44** · 20s · **[PHOTO]** *VO:* "They have rebuilt the ship from the keel up. Not repaired — rebuilt. A new ferrocement hull, eighty-four feet, roughly sixty tons, with upgraded engineering. Hundreds of volunteers have passed through since 2012. In 2025 alone, more than fifty people came to work on her. The paint went on inside and out, finishing in December 2025. And in October, a Mexican artist and crew member named Corina del Carmel painted the ship's new eyes on the bow — the traditional mark on a junk, so the vessel can see where it's going." *Asset:* Drydock sequence ending on the eyes. The project posted these in 2025–26; they're your best recent material. **Scene 45** · 12s · **[PHOTO]** *VO:* "What's left is the interior — systems, outfitting, rigging. In March of 2026 the old crew and the new crew sat down together to go through timelines and budgets and figure out, honestly, what it takes to get her back in the water. They are not done. They have been not-done for fourteen years." **Scene 46** · 18s · **[PHOTO]** → **[AI-OK]** *VO:* "And there's something almost too neat about the fact that this particular ship — named for the philosopher of permanent change — has spent a decade and a half being disassembled and remade, until almost nothing original remains except the shape of the thing and the people who keep showing up. You cannot step in the same river twice. You cannot rebuild the same ship either. But you can keep it moving." *Asset:* Slow push on the painted eyes, dissolving to open water. **Scene 47** · 10s · **[GRAPHIC]** *VO:* "The Heraclitus is still taking volunteers in Roses, and still raising money to finish. Links below if you want to look into it — I'm not affiliated, I just think it deserves to float." --- ## PEXO WORKFLOW NOTES **Render in segments, not in one pass.** Pexo's clips run 5–120 seconds. Each of the 8 segments above sits under that ceiling deliberately. Render them individually, review each, then stitch — in Pexo if it supports assembly, otherwise in CapCut, Resolve, or Premiere. Trying to one-shot nine minutes will burn credits and give you no revision granularity. **Credits.** Consumption scales with length, and unused subscription credits don't roll over. The stills-heavy approach here is deliberately cheap: image-to-video with subtle motion costs far less than full generative scenes. Roughly 60% of this film is animated photographs. **Free tier watermarks exports.** You'll need a paid tier to publish. **Voice.** Generate the full VO as one continuous pass if Pexo allows it, then cut to picture. Segment-by-segment VO generation tends to drift in tone and pacing between renders. **Use Visual Feedback for the ship shots.** Generative motion applied to photographs of real structures will sometimes warp masts and rigging. Draw on the frame and tell it to hold the geometry still. --- ## FACT-CHECK CARRYOVER All source verification from the previous draft still applies. The items that matter most: - **NOAA weather-data claim (Scene 23)** — sourced from a third-party timeline, not the project's own site. Verify or cut. - **Expedition count** — site says 13, Wikipedia and Ecotechnics say 12. Script avoids the number. Keep it that way. - **No launch date.** An older version of their history page promised a 2022 launch. It passed. The current site gives no target. Don't invent one. - **The Mark Twain quote** on their Join the Voyage page is a documented misattribution. Still omitted. Leave it out. - **Length:** 84 feet only. The site says 24m, Factum Arte says 25m.
