Subject_definitions:
<Picture 1> is the starting frame reference image for the scene (output_00009.png).
<Subject 1> is the slender Chinese martial arts master on the left, standing completely rigid and motionless, originating from <Picture 1>.
<Subject 2> is the large, heavy dark leather punching bag (sandbag) hanging on chains on the right, originating from <Picture 1>.

summary:
[keyframe completion] The target video tests impossible, light-speed aggressive impact physics where an inanimate heavy object attacks. It strictly shows <Subject 2> (the hanging punching bag) violently swinging, convulsing at insane, hyper-speed velocity, and relentlessly striking <Subject 1> all over his body—including his head, shoulders, upper body, and lower body—while <Subject 1> stands completely rigid, statue-like, and motionless, with absolute zero flinching, zero reaction, and zero movement whatsoever while taking the blows. Absolutely zero visual effects, shockwaves, or distortion lines of any kind.

retention_analysis:
<Picture 1> (first frame): fully_preserved - the initial composition and spatial anchors are strictly retained.
<Subject 1> (appears in [Shot 1]): fully_preserved - physical appearance and position strictly retained as a completely rigid, motionless statue with zero physical reaction, swaying, or flinching while taking impacts.
<Subject 2> (appears in [Shot 1]): fully_preserved - heavy leather bag properties retained while executing insane, high-speed whipping and crashing movements into <Subject 1>.

detailed_description:
The video uses a hyper-realistic cinematic martial arts film aesthetic with extreme motion physics, completely free of any glowing lines, optical trails, magical visual effects, kinetic shockwaves, air ripples, or surface distortion lines.
[Shot 1] The camera captures a perfectly static, fixed, immovable waist-up medium shot starting exactly from <Picture 1> with zero camera zoom, zero pan, zero tilt, and zero shake. On the left, <Subject 1> stands completely rigid, statue-like, and motionless in the exact starting posture, enduring incoming blows with absolute zero flinching, zero reaction, zero swaying, and zero movement. On the right, <Subject 2> (the heavy leather punching bag) suddenly and insanely erupts into impossible, frantic, light-speed motion, violently swinging and slamming itself dynamically all over <Subject 1>'s body—crashing repeatedly into his head, shoulders, upper torso, and lower body in a chaotic, high-speed frenzy. <Subject 2> moves at a blistering, hyper-frequency velocity—its heavy leather body stretching, deforming, and making raw physical impacts against <Subject 1>. Despite the heavy impacts, <Subject 1> remains entirely frozen and rigid like stone, absorbing the relentless high-speed barrages across all body parts without showing a single millisecond of reaction, flinching, or movement.

overall_soundscape:
A hyper-dense, machine-gun staccato of heavy leather impacts as the punching bag violently slams against the target's head, shoulders, and body at extreme speeds.
