Answer

Add your own subtitles to a web video with NoaLingua

Attach SRT or VTT, correct the timing and make every word clickable

In short

Yes. On a page with a usable video, choose Your subtitle file for this video, select an SRT or VTT file, inspect the preview and attach it. NoaLingua can shift the whole track earlier or later, remembers it for that page and applies translation, word lookup and saving locally.

Short answer Yes. A local SRT or VTT can become NoaLingua’s timed text for a web video and stay associated with that page.

Step by step

Doing it with NoaLingua

  1. 1

    Open the video page

    Use the NoaLingua toolbar popup or the corner menu on a page with a playable video.

  2. 2

    Choose the subtitle file

    Select Your subtitle file for this video and open a local .srt or .vtt file.

  3. 3

    Align and study

    Shift all lines earlier or later until they match, then use translation and word cards normally.

The detail behind the NoaLingua answer

What the file supplies

A generic video may expose no captions even when you already have a legal timed subtitle file. Loading it supplies both the text and timestamps NoaLingua needs for the overlay.

It does not upload the file, search subtitle sites or create a new transcript.

What timing correction can do

A global offset fixes the common case where every line is early or late by roughly the same amount. Half-second and one-second controls make that correction quick.

Drift and individual bad timings need a real subtitle editor; NoaLingua does not pretend the global control is one.

More questions people ask NoaLingua

Which subtitle formats work?

SRT and WebVTT.

Is the file uploaded?

No. It is read locally.

Can I edit one subtitle line?

No. NoaLingua shifts the whole track rather than editing individual cues.
