Clarify dataset licensing and canonical release format. We corrected an ambiguity in the previous dataset access description. The canonical VidNum-1.4K release consists of source URLs, timestamps, annotations, metadata, and evaluation scripts. Annotations and metadata are released under CC BY 4.0, while the evaluation code is released under the MIT License. Copyright of the original videos remains with their respective copyright owners and hosting platforms. Temporary hosted clips are provided solely for benchmark validation, reproducibility, and academic research convenience during the review/research process, and do not imply relicensing or ownership transfer.
