photorealistic 20-second vertical 9:16 smartphone video filmed as one continuous handheld take on an iPhone 17 Pro 1x camera inside a real helicopter flying above an active volcano. 4K, 30fps, natural HDR, deep depth of field, constant helicopter vibration, micro-shake, autofocus/exposure breathing, realistic wind and rolling shutter. It must feel spontaneous, dangerous and real, never cinematic or CGI. Use @image_start for the helicopter interior and opening composition: open rear cargo door, grey quilted metal interior, floor rails, red cargo netting, mountains outside. A huge 1m x 1m clear plastic bag completely filled with already-popped white/yellow popcorn sits centered on the floor. Keep the bag visually identical throughout. CHARACTER LOCK: @image1 is the main character wearing a white T-shirt, grey shorts and white sneakers. His face, identity, hairstyle, skin tone, body proportions and clothing must remain identical in every frame. A second crew member assists. 0-4.3s: Start exactly like @image_start. The main character unclips the bag. Both men shout "Ready?!" "Yeah! Go!" "Push it, PUSH IT!" They struggle to shove the heavy bag toward the open door. Strong wind pushes it backward. It moves only inches per shove, plastic violently crinkling, popcorn shifting inside. His sneaker slips, he catches himself, then they finally push the bag out. 4.3-5.5s: Camera rushes to the doorway and tilts downward. The bag tumbles through the air toward the glowing volcanic crater. 5.5-8.8s: The bag hits molten lava and the plastic instantly vaporizes. Thousands of popcorn pieces explosively launch upward as one huge dense white column, matching @image_eruption, with glowing orange-red lava beneath. The character leans out, points downward and reacts in disbelief. 8.8-11s: Matching @image_return, the popcorn reaches helicopter altitude and becomes a massive horizontal storm blasting through the open door. Popcorn violently hits the character, cabin and camera. He shields his face as the camera jolts. 11-13.5s: The cabin is filled with swirling popcorn. The character is half-buried. He picks up one piece, eats it, chews twice, looks directly into camera and deadpans: "...it's warm." 13.5-16s: The second crew member bursts out laughing. Both laugh uncontrollably while popcorn swirls everywhere. Another gust blasts through the cabin. Camera shakes violently and the video ends abruptly mid-chaos. PHYSICS: realistic heavy bag resistance, strong wind interaction, instant plastic vaporization, explosive unified popcorn column, horizontal return blast caused by wind/updraft, and popcorn swirling rather than falling straight down. CAMERA: one continuous iPhone 17 Pro 1x handheld shot. No cuts, zooms, slow motion, gimbal stabilization, cinematic bokeh, lens flare or artificial lighting. AUDIO: No music. Loud helicopter rotor, engine and wind throughout. Dialogue heavily muffled by rotor noise. Include plastic crinkling, grunts, volcanic WHUMP/BOOM, roaring rising popcorn, violent popcorn impacts, laughter and one audible crunch before "...it's warm." No captions, logos, watermarks, overlays, UI or title cards.
