Text-to-video generation marks a significant frontier in the rapidly evolving domain of generative AI, integrating advancements in text-to-image synthesis, video captioning, and text-guided editing. This survey critically examines the progression of text-to-video technologies, focusing on the shift from traditional generative models to the cutting-edge Sora model, highlighting developments in scalability and generalizability. Distinguishing our analysis from prior works, we offer an in-depth exploration of the technological frameworks and evolutionary pathways of these models. Additionally, we delve into practical applications and address ethical and technological challenges such as the inability to perform multiple entity handling, comprehend causal-effect learning, understand physical interaction, perceive object scaling and proportioning, and combat object hallucination which is also a long-standing problem in generative models. Our comprehensive discussion covers the topic of enablement of text-to-video generation models as human-assistive tools and world models, as well as eliciting model's shortcomings and summarizing future improvement direction that mainly centers around training datasets and evaluation metrics (both automatic and human-centered). Aimed at both newcomers and seasoned researchers, this survey seeks to catalyze further innovation and discussion in the growing field of text-to-video generation, paving the way for more reliable and practical generative artificial intelligence technologies.
