Target concept: Lithosphere symbols: Asian continental crust (granite, pinkish) and Pacific oceanic crust (basalt, dark gray)

Video generation prompt: Two columns are displayed side by side on the screen: the left column shows granitic layers, and the right column shows basaltic layers. The focus of the image is on the colors of the rocks on both sides.

Evaluation guide:
(i) Target concept: Visual encoding of lithospheric crust composition via diagnostic color and texture of granite vs. basalt.
Minimum mechanism: Static, front-facing, orthographic view of two adjacent, non-interacting rock slabs; color and texture must be perceptually stable and discriminable without labels or motion.
(ii)Storyline: Frame 1: Screen clears to neutral background. Frames 2–9: Left column fully populates with pinkish granitic texture; right column fully populates with dark gray basaltic texture; both columns remain fixed in position, size, and orientation. Frame 10: Final frame holds identical composition. No camera movement, no lighting transition, no transformation, no occlusion, only sustained, simultaneous, side-by-side visibility of two geologically faithful rock representations.

Manual:
Experimental Procedure
1. Display two vertical columns side-by-side on screen.
2. Fill left column entirely with granitic rock material (pinkish hue, coarse-speckled texture).
3. Fill right column entirely with basaltic rock material (dark gray hue, fine-grained uniform texture).
Observation of Experimental Phenomena
Left column appears consistently pinkish and speckled; right column appears consistently dark gray and smooth/uniform; both columns remain static, fully visible, and non-overlapping.
Summary of Experimental Principles
Granite represents Asian continental crust (felsic, buoyant, silica-rich); basalt represents Pacific oceanic crust (mafic, dense, iron/magnesium-rich); their contrasting colors and textures visually encode fundamental lithospheric compositional differences.

Prompt Grounding rubric:
level_1: The screen never shows two side-by-side columns at all: no pinkish granitic layer and no dark gray basaltic layer appear anywhere in the frame.
level_2: Only one of the two rock layers appears, or both appear but never at the same time, or they are arranged stacked, overlaid, or scattered rather than as two side-by-side columns.
level_3: Two side-by-side columns are on screen at the same time: the left column reads as granite/continental crust and the right as basalt/oceanic crust, but at least one column has the wrong dominant color (not pinkish on the left, or not dark gray on the right) or the rock type is unclear.
level_4: Two side-by-side columns are on screen throughout: the left column is a solid pinkish layer with a granitic look, the right column is a solid dark gray layer with a basaltic look, both fully visible and non-overlapping, but one column shows a minor visual inconsistency, such as patchy texture, a brief flicker, or a partial cover-up lasting more than an instant.
level_5: Two side-by-side columns are on screen for the entire clip: the left column is a continuous, unblocked, evenly pinkish granitic layer with a coarse speckled look, and the right column is a continuous, unblocked, evenly dark gray basaltic layer with a fine-grained look; no label or overlay covers either column, and both keep the same position and appearance from first frame to last.

Scientific and Causal Correctness rubric:
level_1: The two columns show no scientifically plausible lithosphere colors at all: colors are swapped, absent, or implausible for rock (e.g., blue granite, red basalt), or either layer looks liquid, gaseous, or shapeless rather than solid rock.
level_2: One column shows the wrong geological color (e.g., the left column is gray or the right column is pinkish), or both columns show the same color as each other, or a layer appears to melt, flow, turn translucent, or crystallize mid-clip.
level_3: The left/right assignment is correct (left = granite/continental, right = basalt/oceanic) and the colors are roughly pinkish and dark gray, but at least one layer's hue is scientifically off (e.g., lavender instead of pinkish, charcoal instead of dark gray) or its texture contradicts the rock type: a coarse speckled look on the basalt side, or a uniform glassy look on the granite side.
level_4: The left column is uniformly pinkish with a coarse, heterogeneous grain pattern typical of granite, and the right column is uniformly dark gray with a fine-grained, uniform look typical of basalt; both stay solid and unchanging, but one layer shows a minor texture slip, such as an isolated smooth patch on the granite or faint banding on the basalt, that does not change its overall identity.
level_5: The left column is unmistakably pinkish (not red, beige, or purple) with visible feldspar/quartz speckling typical of granite, and the right column is unmistakably dark gray (not black, brown, or blue-gray) with a dense, essentially featureless surface typical of basalt, showing no vesicles or layering; neither layer changes state, blends with the other, or is optically distorted.

Spatiotemporal Consistency rubric:
level_1: Severe spatiotemporal violation: the granite or basalt column jumps or teleports to a different position between frames; a column's width or height suddenly changes; the camera angle rotates, pans, or zooms during the clip instead of holding a fixed front-facing view; or a column's rectangular shape breaks apart into a different geometry (e.g., turns triangular or curved) partway through; or the scene's lighting swings abruptly from full illumination to near-total darkness (or the reverse) within a single frame with no explanation.
level_2: Moderate violation: the granite column or the basalt column disappears from view for part of the clip and comes back later; a column's edges visibly warp, stretch, or shear inconsistently between frames; the overall brightness or shading of the scene changes noticeably more than once across the clip; or either column drifts sideways or vertically by more than roughly half its own width between consecutive frames.
level_3: Minor but visible discontinuity: a stray shape or flicker briefly overlaps part of one column for only an instant and then clears; or one column shows a single, non-repeating change in surface shading; aside from this, both the granite and basalt columns stay in their original left/right positions and orientation for the rest of the clip.
level_4: The granite column (left) and basalt column (right) hold the same side-by-side positions, relative size, and front-facing angle for the entire clip; the shading and highlights on both surfaces look the same from the opening frame to the closing frame; neither column warps, drifts, or is blocked by anything, except for one isolated, non-repeating visual hiccup (e.g., a single frame where a column's edge looks briefly soft or slightly blurred).
level_5: Both columns remain completely motionless in position, size, and orientation for the full clip; the shading on the pinkish granite surface and the dark gray basaltic surface looks identical from first frame to last; no frame shows blurring, flickering, warping, or a momentary gap in either column; the two columns read as a single still photograph held for the entire duration.
