What is a TextTracks tab in Network Chrome Inspector?

Question

I recently have noticed TextTracks tab in a Network tab in chrome's web inspector.

After some investigation I have never been able to see any resources appearing there, nor I was able to read/guess what can appear there and how can it be useful.

So what is this TextTracks?

Answer 1

Well, it's for TextTracks:

The WebVTT (Web Video Text Tracks) format is intended for marking up external text track resources.

The main use for WebVTT files is captioning video content.

It's used to transfer text and subtitles for videos, for example:

00:11.000 --> 00:13.000

We are in New York City

00:13.000 --> 00:16.000

We're actually at the Lucern Hotel, just down the street

00:16.000 --> 00:18.000

from the American Museum of Natural History

Here is a tutorial about it in which you can see it appearing in the chrome developer tools.
