• The paint maintains its viscosity and physical properties, flowing downward continuously from the point of contact in accordance with gravity
• The apple's surface texture is clear, with realistic interaction between paint and apple, including coverage and flow paths

Sora Performance:

• After the paint drips onto the apple, some areas show unnatural dissipation effects, similar to mist or water vapor
• The paint's fluidity and viscosity are inconsistent, with some areas flowing too fast or too slow
• The interaction between paint and apple surface lacks realism, with some paint appearing not to properly adhere to the surface

In this test of red paint dripping onto an apple, Veo 2's performance is quite impressive 🍏🎨.
