Generative AI for Text-to-Video Generation: Recent Advances and Future Directions

Text-to-video (T2V) generation has recently emerged as a transformative technology within the field of generative AI, enabling the creation of realistic, temporally coherent videos based on natural language descriptions. This paradigm provides significant added value in many domains such as creative media, human-computer interaction, immersive learning, and simulation. Despite its growing importance, systematic discussion of T2V is still limited compared with adjacent modalities such as text-to-image and image-to-video. To alleviate the scarcity of discussions in the T2V field, this paper provides a systematic review of works published from 2024 onward, consolidating fragmented contributions across the field. We survey and categorize the selected literature into three principal areas, namely, T2V methods, datasets, and evaluation practices, and further subdivide each area into subcategories that reflect recurring themes and methodological patterns in the literature. Emphasis will then be placed on identifying key research opportunities and open challenges that need further investigation.
