What happens to subtitles when you download a video
Captions you see on a platform usually aren't in the video file. Which kinds survive a download, which don't, and how to get subtitles when you need them.

You download a video that had captions, open it, and the captions are gone. Nothing broke: on most platforms the subtitles were never part of the video. They're a separate track, or a separate file, drawn over the picture by the player. Whether they survive depends on which kind they were.
Three kinds of caption, three outcomes
What you see on screen could be any of these, and they behave differently:
| Kind | Where it lives | Survives a download? |
|---|---|---|
| Burned in | Part of the picture itself | Always — it's pixels |
| Platform captions | A separate track the player draws | No |
| Auto-generated | Made by the platform on demand | No |
The middle two are the reason a video that was fully captioned on YouTube arrives silent of text. They were never in the video stream, so fetching the video stream doesn't collect them.
Why creators burn captions in
On Instagram, TikTok and Reels-style feeds, most captions are burned in — typed into an editing app and rendered into the picture before upload. Vertical video is usually watched with the sound off, and a creator can't rely on a viewer turning captions on, so the text is made part of the frame.
That's why a downloaded Reel usually keeps its on-screen text while a downloaded YouTube video usually doesn't. It isn't a difference in the downloader; it's a difference in where the words were put.
Auto-generated captions aren't a file
YouTube's automatic captions are produced by speech recognition and served alongside the video on request. There's no caption file sitting next to the video waiting to be collected — and their accuracy varies enough that they're a starting point rather than a finished transcript.
What this site does and doesn't give you
Downloads here contain video and audio. Subtitle tracks aren't extracted, so a file you get from this site carries only the captions that were burned into the picture.
If subtitles are the point of the exercise, a couple of tools do fetch them — yt-dlp and some installable downloaders pull caption files in whatever languages the platform holds. That comparison covers what each one does and where it's the better choice.
Getting subtitles another way
When you have the video and need the words, three routes work:
- Your own upload — YouTube Studio lets you download the caption file for a video on your own channel, including the auto-generated one after you've corrected it.
- A transcript from the platform — YouTube's web player has a transcript panel under the video, which can be copied out as text. It carries timestamps but no formatting.
- Transcribing the file yourself — speech-recognition tools produce an .srt from a video file you already have, which is the only option when the source never published captions at all.
If you have an .srt and the video separately
Most players load a subtitle file automatically when it sits in the same folder with the same name — video.mp4 and video.srt. VLC does this without configuration, and it works on phones as well as computers.
For subtitles that must travel with the file — sending it to someone, putting it in a presentation — the track has to be muxed into the container instead. MKV handles subtitle tracks comfortably; MP4's support is narrower, which is part of the broader story in containers vs codecs.
A word on accuracy
Auto-generated captions misread names, technical terms and anything spoken over background noise. If the transcript is going into something that matters — a subtitled clip you'll publish, a quote in a document — read it against the audio first. What you may keep covers the separate question of reusing someone else's material.
