Processing and narrating a video with GPT-4.1-mini's visual capabilities and GPT-4o TTS API

# Processing and narrating a video with GPT-4.1-mini's visual capabilities and GPT-4o TTS API This notebook demonstrates how to use GPT's visual capabilities with a video. Although GPT-4.1-mini doesn't take videos as input directly, we can use vision and the 1M token context window to describe the static frames of a whole video at once. We'll walk through two examples: 1. Using GPT-4.1-mini to get a description of a video 2. Generating a voiceover for a video with GPT-4o TTS API ## 1. Using GPT's visual capabilities to get a description of a video
