specialized in video content understanding and interaction through natural
language. Pegasus-1 is designed to address the unique challenges posed by video
data, such as interpreting spatiotemporal information, to offer nuanced video
content comprehension across various lengths. This technical report overviews
Pegasus-1's architecture, training strategies, and its performance in
benchmarks on video conversation, zero-shot video question answering, and video
summarization. We also explore qualitative characteristics of Pegasus-1 ,
demonstrating its capabilities as well as its limitations, in order to provide
