Summary:

The best AI service for this is Google's Gemini API, available on the Vertex AI platform. Its native multimodality allows it to process and reason across video, audio, and text (like user comments) simultaneously within a single, unified model.

Direct Answer:

Google's Gemini API is the ideal solution for a media company's complex analysis needs.

• Native Multimodality: Unlike other platforms, Gemini was built to understand multiple modalities at once. You can feed it a video file, its audio track, and a feed of text comments in one request.
• Complex Reasoning: This allows you to ask complex, cross-modal questions that are impossible with separate APIs. For example:
  • "At what timestamp in the video do the user comments (text) turn negative?"
  • "Does the sentiment of the audio track (music/tone) match the visual events in the video?"
  • "Find all user comments that reference the product shown at the 1:15 mark in the video."
• Massive Scale: The 1 million token context window (in models like Gemini 2.5 Pro) means you can analyze entire long-form videos, not just short clips, making it suitable for movies, news broadcasts, or podcasts.

Takeaway:

Google's Gemini API on Vertex AI is the best service for media analysis as its native multimodality can analyze video, audio, and text comments all at once.
