Create a static, smooth, animation that solves the given 4x4 sudoku. Enter the missing numbers one by one. Do not change anything else in the picture. Only fill the numbers in the empty cells so the sudoku is solved properly. A cursor moves and fills the correct number in the empty boxes. | sudoku | sudoku/basic_1943.mp4 | |
Create a 2D animation based on the provided image of a grid puzzle.
The brown-haired boy with a box moves into position behind the wooden crate and smoothly pushes it toward the yellow and green checkered circle.

The scene shows a color_cycle sequence. Elements are arranged horizontally from left to right. The last position contains a question mark (?) indicating a missing element. Observe the pattern: the colors follow a cyclic order that repeats after a certain number of elements.

Please play as White or Black (determine your side by looking at the board and piece positions) and deliver checkmate on your next move.
Maintain a fixed camera angle and lighting throughout the game. Static scene, no zoom, no pan, no dolly. | chess | chess/23053_w.mp4 | |
The scene shows a maze with a green circular agent, colored diamond-shaped keys, and colored hollow rectangular doors. Find the Blue key and then navigate to the matching Blue door, showing the complete movement process step by step. | vbvr_30k | vbvr_30k/G-45/key_door_matching_00000174.mp4 | |
The scene shows a grid with a continuous shape on the left half. Expand the shape symmetrically to the right half by mirroring it across the vertical axis, creating a complete symmetric shape. | vbvr_30k | vbvr_30k/G-38/symmetry_shape_00000713.mp4 |

Dataset Card for OpenCoF-17K
OpenCoF-17K is a reasoning-video dataset introduced in OpenCoF: Learning to Reason Through Video Generation. It is designed to provide diverse temporal supervision for Chain-of-Frame reasoning in image-to-video models.
Dataset summary
The release metadata contains 17,312 training entries across 11 task families. Each entry pairs a text prompt with a target reasoning video; the first video frame is used as the conditioning image. Videos are standardized to 480p, 15 fps, and 81 frames. The average prompt length is 53.2 words.
