subject_definitions: <Subject 1> = the rider's cockpit at the rider's own point of view in <Picture 1>: two hands in black gloves with pale knuckle stitching and black wrist cuffs gripping a red cross-braced handlebar; black handguards with brushed aluminium lever arms arcing over each grip; a red front mask rising above the bar clamp with a dark oval recess and a small pale circular detail on its face; a small dark instrument display set into the clamp between two bright bolts; black hydraulic lines and cables looping down and back from each lever. Grip spacing, handguard and lever arcs, mask and display position, cable routing and the red plastic tone all derive from <Picture 1>. <Subject 2> = the red enduro motorcycle beneath the viewpoint in <Picture 1>: the machine whose motion drives every frame — red front plastic, black fender edge, fork lowers and front wheel, visible only in the low-mounted and descent framing. It is the same machine each time it enters frame; only how much of it is visible changes. <Subject 3> = the volcanic field in <Picture 1>: black and charcoal basalt cinder and broken lava rock across the left side and the entire foreground; a molten channel of incandescent orange-yellow lava running from mid-left across the middle distance and down toward the lower right, with brighter pooled pockets where the crust breaks; long airborne ember streaks cutting across the right of frame; ash and smoke plumes rising from the field; a dark volcanic ridge line closing the horizon; an overcast grey-white sky above it. Geography, horizon bearing and light direction are preserved from <Picture 1>. summary: [reference generation] 8.00 seconds, five hard-cut camera setups (creator-directed multi-cut, deviating from the single-continuous-shot default). A POV enduro rider runs a live lava field at full throttle — flat out across cinder and broken basalt, hammering at the bar clamp, banking hard into a right-hander, pitching up a cinder ridge and plunging down the far side. retention_analysis: <Picture 1> ([Shot 1] composition anchor / first frame): partially_preserved — retained: <Subject 1>'s cockpit geometry (grip spacing, handguard and lever arcs, red mask with dark recess, clamp display between its two bolts, cable routing, black wrist cuffs), used in Shots 1, 2 and 5; <Subject 2>'s machine geometry (red front plastic, black fender edge, fork lowers, front wheel), used where it enters frame in Shots 2 and 5; <Subject 3>'s world (black cinder and basalt across the left and foreground, the molten channel bearing from mid-left to lower right, ember streaks on the right, ash plume positions, ridge line bearing, diffuse overcast key from above and behind the terrain, warm emissive bounce from the lava at camera-right), used in all five shots as fixed geography and light. Released per directed setup: framing, mount height, viewing distance, field of view, depth of field and bokeh all change at each hard cut, and pose, lean, pitch and shake are animated rather than frozen. No facial likeness is retained or needed — the rider's face and helmet never enter this point-of-view frame. detailed_description: Visual treatment: dim high-altitude overcast daylight under one large diffuse source from above and behind the terrain, flattening the rock into charcoal greys and holding the sky near neutral white without clipping; the only saturated light in frame is emitted by the lava itself — an incandescent orange-yellow bounce rising low from camera-right that throws warm rim light on the lever arms, the underside of the red mask and the inner edges of both gloves. No fill light, no vignette, no added lens flare. Optics: wide action-camera perspective at the helmet mount with mild edge falloff, narrowing to a tighter arc at the bar-clamp mount; deep focus from roughly 0.4 m to the ridge line at the helmet mount so the lava channels stay legible, shallower in the low mount where the near lever arm softens; fine natural sensor grain, no synthetic sharpening. Motion blur is real and forward-vectored — the cinder bed streaking radially away from frame centre. Delivery 9:16, crop centred on the bar clamp and the molten channel, ridge line and smoke holding the upper third. Inherited motion palette — this camera is bolted to the rider and inherits the head, and applies to every setup below: (a) 6–12 Hz chatter of ±1.5–4° yaw and roll from engine and surface aggregate; (b) single-frame 8–15° pitch spikes on rock or slab strikes; (c) sustained 20–35° roll banks held through a corner, then released; (d) pitch excursions from −16° nose-down to +25° nose-up under climbing, cresting and dropping; (e) sudden 3–8° yaw corrections as the rider countersteers, with the bar and lever arms visibly swinging in and out of frame. None of these stops for a cut. Shot 1 — 00:00.000–00:01.600. Helmet mount, high over the bars; the opening framing matches <Picture 1> exactly at 00:00.000. Both gloved hands and the full bar width sit in the middle third, the red mask and dark display below the clamp, the black cinder bed raking away from the bottom of frame, the molten channel crossing from mid-left to lower right, ember streaks cutting the smoke on the right, the dark ridge line and ash plumes across the upper third, overcast sky above. Screen direction: forward along the camera z-axis. Motion: (a) chatter running continuously, cinder and broken rock streaking under the bars at full-throttle rate; at 00:00.800 the front tyre crosses a slab edge — a (b) 9° pitch spike snaps the horizon down and back — then the frame recovers; embers sweep past frame right; the engine note climbs across the last half second. HARD CUT — 00:01.600. Shot 2 — 00:01.600–00:03.300. Bar-clamp mount, low over the triple clamp. Gloved hands now at the extreme left and right frame edges, the red mask and dark display filling the lower centre, the black fender edge and fork entering at the bottom, the cinder bed filling the whole frame as a hard field of black slag with the molten channel flaring along the right edge. Screen direction: forward along the camera z-axis. Motion: this is the bouncing peak — the frame lives in contact vibration, each rock strike producing a (b) 12–15° vertical jolt with the slag strobing under the wheel and the horizon legible only in fragments between jolts; at 00:02.600 the rider makes a (e) 6° yaw snap left to skirt a raised slab, the left lever arm swinging into frame, the rear stepping a hand's width before it re-grips on cinder. Tyre crunch and chain slap are loudest here. HARD CUT — 00:03.300. Shot 3 — 00:03.300–00:04.900. Helmet mount, tipped into the right-hand bend. The usable track curves right between raised basalt walls with the molten channel running along the inside of the corner, so the lava flushes brightest through the right of frame; the rider banks the bike into a (c) sustained 27° right roll and holds it through the apex, the horizon rotating counter-clockwise across frame while the ridge line swings toward the left edge and the ash plume drops low right. Screen direction: forward along the camera z-axis, curvature to the right. Motion: (a) chatter rides on top of the held bank; at 00:04.100 the front washes briefly on loose slag and the rider makes a (e) 5° countersteer snap out of the lean and back in, the bar visibly swinging; at 00:04.700 the bank releases and the horizon levels as the ground straightens. HARD CUT — 00:04.900. Shot 4 — 00:04.900–00:06.500. Helmet mount, driven by the terrain. The line tips up a steep cinder ridge: a (d) +24° nose-up pitch fills the upper frame with black ridge grass-less rubble, exposed stone and the overcast sky rolling down toward the top edge; two hard rock strikes at 00:05.500 and 00:05.800 punch (b) 10–14° pitch spikes through the climb; at 00:06.200 the bike crests and the pitch holds a beat before the front goes light. Screen direction: forward along the camera z-axis, then upward. HARD CUT — 00:06.500. Shot 5 — 00:06.500–00:08.000. Helmet mount on the plunge. The pitch swings through to (d) −16° nose-down as the front drops off the crest and <Subject 2>'s red front plastic, black fender edge, fork lowers and spinning front wheel enter the bottom of frame for the first time, with the molten channel flaring along the lower right and ember streaks raking past. Screen direction: forward along the camera z-axis, then downward. Motion: the wheel skips across embedded rock; at 00:07.300 the rear steps loose on slag and the rider makes a (e) 7° yaw-and-roll correction that re-grips the line, the bar snapping across frame. Final image: the cinder bed running away downhill between the basalt, the lava channel glowing low right, the wheel still spinning and the frame still chattering — nothing settles, the run continues past the last frame. Continuity locks: Keep unchanged: cockpit geometry, grip spacing, glove and garment state, machine build and red plastic tone, black cinder bed and molten channel bearing, ridge line and ash plume positions, light direction (diffuse overcast from above and behind, warm emissive bounce from the lava at camera-right), forward screen direction, gravity physics. Facial likeness is not reproducible — the rider's face and helmet never enter this point-of-view frame. Exclude: morphing, warping, dissolves, identity drift, geometry warping, invented grass, mud or plastic course stakes, a discovered rider's helmet or face appearing in frame, added lens flares, arbitrary colour casts, unmotivated cuts (the four cut points above are directed and motivated), text overlays, watermark. No added captions, subtitles, overlays or watermarks. overall_soundscape: Open air, no reverb, mic mounted with the camera so it takes every jolt. A single-cylinder engine note under load throughout, rising in pitch across Shot 1 and holding near peak through Shots 2 and 3; heavy tyre crunch into cinder and slag with rolling chips underneath; small chips ticking off the fender and the handguards; chain slap on the slab strikes; brake and lever clack at the correction beats (00:02.600, 00:04.100, 00:07.300); steady wind buffeting across the mic capsule that swells on the descent. Under everything, a low continuous volcanic rumble with sparse crackle and pop when the molten channel is closest to frame, from 00:03.300 to 00:04.900. At 00:04.900 the note loads and drops a step as the climb begins, pulls clean over the crest at 00:06.200, then free-spins on the plunge. No dialogue, no voices, no crowd. non_diegetic_music: N/A — no score is requested or established for this scene; engine, cinder and the lava field's own low rumble carry the rhythmic load.
