Automatically Add Video Captions to YouTube via HubSpot

Automatically Add Video Captions to YouTube via HubSpot
2:24

At Antidote 71, we’re big believers in making your marketing smarter, faster and more effective. So, when HubSpot rolls out a new feature that makes life easier for video marketers and improves accessibility for audiences, you bet we’re paying attention.
This latest update is one of those small ones that can make a significant difference quietly.

 

What’s New?

You can now automatically add captions to your YouTube videos when posting through HubSpot. No more downloading caption files, manually uploading them to YouTube or settling for those barely passable auto-generated captions YouTube kicks out.

HubSpot’s AI-generated captions are cleaner, more accurate and far better for the user experience.

 

Why This Matters for Marketers

We’ve seen firsthand how captions boost video performance:

  • They improve accessibility for viewers.
  • They increase watch time and engagement (especially on sound-off mobile viewing).
  • And they can positively impact your video SEO.

Let’s face it, YouTube’s default captions miss the mark too often. HubSpot’s AI-generated captions are noticeably more reliable and readable, helping you deliver a polished, professional experience without the extra work.

 

How It Works (And Who Gets It)

If you’ve enabled AI file analysis in HubSpot, captions will automatically generate for every video you upload.

If you’re part of HubSpot’s video marketing beta, you can generate captions on a video-by-video basis without enabling full AI file analysis. And if you prefer to handle it yourself, uploading a VTT caption file manually is still an option.

When you post your video to YouTube through HubSpot, the caption file is shared automatically, no extra steps, no extra hassle.

 

Available for:

  • Professional Customer Platform
  • Enterprise Customer Platform
  • Marketing Pro
  • Marketing Enterprise

 

Our Take

We love updates like this because they do two things well:

  1. Save time for marketers and teams already overwhelmed.
  2. Deliver a better, more accessible experience for audiences and that matters.

If your team’s producing video content, this is a no-brainer feature to start using.

Need help setting this up or optimizing your video marketing strategy?

We’d be happy to walk you through it. As a HubSpot platinum partner, we’re here to help you get more from your tools and turn features like this into ROI.
