YouTube Help (captured 2026-10-23): Shorts can be up to 3 minutes with a square or vertical aspect ratio; reused copyrighted material can trigger Content ID claims. YouTube's blog post of 2024-10-03 announced that from October 15 (2024) uploads up to 3 minutes that are square or taller count as Shorts, not affecting earlier uploads. Side effects documented elsewhere: such videos are no longer eligible for title/thumbnail A/B tests (C3-B336-02).
