Descriptive frequency analysis of video characteristics across the 257 reviewed articles, shown per methodological approach in Fig. 3 and Fig. 4. The review states "Textual features were by far the most utilized features"; the abstract adds the ordering visual features, learners' activities, and interactive features follow. No effect size applies.

• VBL research falls into four main methodological approaches, with tools (57%) and controlled experiments (25%) dominating — related
• VBL tools most frequently use textual and visual features, mainly for recommendation, information extraction, summarization, and navigation — related
