Google Models 404 Error on Analyze Video Block

[Mdickens]

I am trying to get the “Analyze Video” block to receive a Youtube link and pull out certain key pieces of information. However, for either model choice that the block allows, I get the same error:

Here is the remix link for the agent:

Here is a screenshot of how the Analyze Video block is set up:

Hi @Mdickens,

Thanks for the post!

The Analyze Video block can process videos uploaded through a User Input block or videos hosted at a publicly accessible file URL.

As for YouTube videos, I’d recommend using the YouTube blocks instead, or downloading the video first and then uploading it to the Agent.

Hey Alex,

I need to get the transcript of the video, and I want the agent to run autonomously without having to manage the download and reupload of videos somewhere outside the agent. Any suggestions?

Thanks!

Hi @Mdickens,

The Fetch YouTube Captions block should cover this. It gets the transcript directly from YouTube, so there’s no manual handling

Thanks!
