1947 Roswell UFO Crash Found-Footage Recreation

the prompt

[Generation Goal]
Generate a recovered-archival-footage style video that looks like authentic 1947 military documentation film from the Roswell desert. The central subjects are a civilian cameraman, US Army soldiers in 1947-era uniforms, and a small humanoid alien creature. The primary event: a crash site in the hills is filmed, the cameraman is ordered off the premises, the military inspects the wreckage, and a live alien is restrained on a field gurney while it screams and struggles.

The entire video must look shot on a hand-cranked 16mm newsreel camera from 1947: black-and-white film, heavy visible grain, gate weave and frame jitter, vertical scratches, dust and hair in the gate, occasional missing frames and hard jump cuts, flickering exposure, blown-out highlights in the desert sun, soft vintage lens with vignetting, slightly unsteady handheld framing. Audio sounds like a degraded optical soundtrack: muffled mono, constant hiss and crackle, voices slightly distorted, wind buffeting the microphone.

[Stage 1]
0-8 seconds.
Initial state: handheld shot from a ridge overlooking dry desert hills at midday. Thin black smoke rises from scattered metallic debris in a shallow gouge in the earth below. The frame trembles as the cameraman walks forward.
Primary event: the cameraman narrates over the shot, voice muffled through the old microphone: {Something has come down in the hills outside Roswell... the Army's already here.} Two soldiers in 1947 US Army uniforms with M1 helmets enter frame from the right, one raising a gloved hand directly at the lens. He shouts: {Turn that camera off! This area is restricted — leave the premises, now!} The image jerks away as the cameraman backs off, ground and sky swinging through frame, then a hard splice cut with two white frames of leader.
End state: cut ends mid-motion; smoke column and debris field were last seen behind the two soldiers blocking the path.

[Stage 2]
8-15 seconds.
Continue from the previous stage: same desert location, same harsh midday light, same film stock and grain. This footage now reads as the Army's own documentation camera, steadier, on or near a tripod.
Primary event: soldiers move methodically through the debris field. One kneels and turns over a thin, curved metallic fragment that catches the sun with an unnatural mirror sheen; another photographs it with a period Speed Graphic press camera, its flashbulb popping <a sharp flashbulb pop and faint glass tink>. In the background, men carry a covered stretcher toward a canvas military tent. Low wind and indistinct clipped voices under the hiss.
End state: the covered stretcher disappears through the tent flap; the kneeling soldier still holds the metallic fragment. Hard jump cut with a frame of film scratch damage.

[Stage 3]
15-27 seconds.
Continue from the previous stage: interior of the same canvas tent, lit by one harsh bare bulb and a hot on-camera light, deep shadows, smoke haze in the beam. Same soldiers' uniforms carry over.
Primary event: a small grey-skinned humanoid alien, thin-limbed with an oversized hairless head and large dark eyes, lies strapped to a metal-framed field gurney with leather restraints across its chest, wrists, and legs. It arches and thrashes violently against the straps, head whipping side to side, its long fingers clawing at the restraints, emitting a piercing, unearthly shriek <a high, warbling, distorted scream that clips and crackles on the degraded soundtrack>. Three soldiers press down on its shoulders and legs by force, struggling to hold it as the gurney rattles. A fourth man in a medical coat leans in with a metal instrument. From somewhere off-frame, male laughter is heard, casual and unsettling <two or three men laughing lowly in the background>, followed by an offhand muffled voice: {Feisty little fella, ain't he.} The handheld camera pushes in slightly, jittering, occasionally losing focus on the creature's face.
End state: the alien is still restrained and writhing, soldiers still pinning it down, the creature's dark eyes turned directly toward the lens.

[Stage 4]
27-30 seconds.
Primary event: mid-struggle, the film abruptly degrades — frames slip, the image tears and flares white as if the reel runs out, ending on flickering blank leader with dust and scratches <the audio cuts to pure projector clatter and hiss>.
End state: white flickering film leader, no image, faint projector rattle.

[Maintain Consistency]
Keep the black-and-white 1947 16mm film look, grain, scratches, flicker, and degraded mono audio identical across all stages. Keep soldier uniforms (1947 US Army khaki, M1 helmets), the desert location and lighting in Stages 1-2, the tent interior in Stage 3, and the alien's identity (small grey humanoid, oversized head, large dark eyes, thin limbs, restrained on the same gurney) fully consistent. Do not introduce modern objects, vehicles, color, or clean digital image quality at any point.
