Public lessons and worked examples
Learn shared foundations, then work with real industry materials.
Use real clips to record verifiable releases, anonymous identities and player relationships. Distinguish the original broadcast from replays, repair deliverables against the rules, and use two unseen sources to hand off complete packages with evidence-backed unresolved items.
Courses follow your selected language. Revisit the shared foundations as needed; each project below includes real material, practical tasks and a review.

The first five projects build skills; the last combines them on an independent source. Follow the sequence or revisit a project to revise.
Identify a visible release and record its position, type, supporting interval and uncertain boundaries.
Create track segments and their relationships, distinguishing supported continuity from unconfirmed reconnections.
Link events through object references. Do not infer a catch from direction, position or the outcome.
Distinguish broadcast time from action time, mark replay boundaries and map each action uniquely.
Apply rule changes to the data, relationships and review records, showing that the correction covers affected items.
Work independently without example answers or person hints. Keep replays without the original broadcast unresolved, with supporting evidence.
Advanced practice
Use original frames to study balls, rims, visibility and same-ball relationships, then deliver labels for the specified samples and verify them by reading the actual file back.
Six practice units are available, including independent delivery. Formal quality acceptance still requires human reference verification; completing the course does not establish project qualification.
Objects and coordinates
Mark visible balls in original frames, distinguishing balls from hands, shoes and reflections. Align boxes with the source frames and original image coordinates.
Visible and invisible
Assess visible frame content separately from the object's whereabouts. Distinguish partial occlusion, full occlusion, out of frame, confirmed absence and inability to judge.
Inner rim opening
Use consistent boundaries to locate each visible rim's inner opening, handling perspective, side views, soft focus and partial visibility.
The same ball and multiple balls
Track possession, dribbling, occlusion and reappearance across short continuous windows. Record other basketballs in the same image separately.
Quality checks and read-back
Locate missing frames, contradictory states, coordinate-scaling errors and incorrect source mappings. Download the package and read back that same file.
Delivery on unseen sources
Without demonstrations or reference boxes, complete fixed samples from different creators and source recordings. Retain first answers and separate revisions from human quality acceptance.
Start with illustrated explanations, a complete demonstration and boundaries that are easy to misjudge.
Gradually remove hints while building linked records, correcting quality issues and reworking rule changes.
Deliver a complete package from an independent source, retain the first submission, then make targeted revisions.
