How to Add Captions to Videos in Google Drive
You uploaded a training video to a shared Drive folder, someone asked for captions, and there is no obvious button to add them. Google Drive does support caption tracks in its built-in video player, but the feature is tucked away in a menu most people never open, and it only works if you already have a subtitle file to give it. This guide covers how to add captions to videos in Google Drive using the native player, how to make the SRT or VTT file in the first place, and why your captions keep disappearing every time you replace the video.
Step 1: Get a caption file before you touch Drive
Google Drive does not generate captions for you. It plays a caption file that you supply, so the first thing you need is an .srt or .vtt file containing your transcript with timecodes. There is no way around this, so start here.
You have three realistic options:
Type it yourself. Free tools like Subtitle Edit, Aegisub, or even a plain text editor will let you write an SRT by hand. This is accurate and free, but slow. Expect to spend several times the length of the video.
Pull it from another platform. If the same video is already on YouTube with auto captions, you can open YouTube Studio, go to Subtitles, and download the existing track as an SRT, then clean it up. This only helps if the video is already published elsewhere.
Auto transcribe it. Paste a link or upload the file to a transcription tool and export the SRT. This is where Tapescribe fits: it takes the video, returns a timed transcript, and exports SRT, VTT, or plain text, so you have the exact file Drive expects without typing timecodes yourself. Whatever tool you use, read the transcript once before exporting, since names, jargon, and acronyms are where automatic transcription usually slips.
A valid SRT looks like this:
1
00:00:00,000 --> 00:00:03,480
Welcome to the onboarding walkthrough.
2
00:00:03,480 --> 00:00:07,120
We'll start with how to log in for the first time.
Save it with a .srt extension, not .txt. If your text editor silently appends .txt, Drive will not recognise the file as a caption track.
Step 2: Upload the caption file to Google Drive
Upload the .srt or .vtt file to Drive the same way you upload anything else: drag it into a folder, or use New, then File upload.
It does not have to live in the same folder as the video, though keeping them together makes life much easier later. A good habit is a folder per video containing the .mp4 and its caption file, with matching names such as onboarding-walkthrough.mp4 and onboarding-walkthrough.srt. When someone has to re-attach the track in six months, matching names save a lot of searching.
Do not convert the caption file to a Google Doc. If you paste the SRT contents into Docs, Drive can no longer read it as a caption track.
Step 3: Open the video in the Drive player and add the caption track
This is the step people cannot find.
- In Google Drive, double click the video file so it opens in Drive's own preview player. Do not open it in a third party app.
- Let the player load and start or pause playback so the controls appear.
- Click the settings icon (the gear) in the bottom right of the player.
- Choose Captions.
- Select Add caption tracks or Manage caption tracks, depending on your account's interface version.
- A file picker opens showing your Drive files. Select the
.srtor.vttfile you uploaded in Step 2. - Give the track a language and a label, for example "English", then confirm.
The caption file is now attached to that specific video file in Drive. Close the settings menu, and a CC button should appear in the player controls.
If you do not see a Captions option in the gear menu at all, the file is not being played by Drive's native player. That usually means the video was opened through a linked third party app, or the format is one Drive cannot preview. Convert the video to MP4 with H.264 video and AAC audio, which is the combination Drive handles most reliably.
Step 4: Turn captions on and check the timing
Click the CC button in the player to toggle captions on. Scrub to a few points in the video, near the start, in the middle, and near the end, and check that the text matches the audio at each point.
Drift almost always comes from a mismatch between the file you transcribed and the file you uploaded. If you transcribed an earlier cut, added an intro card, or trimmed a false start, every cue after that edit will be offset. Re-export the captions from the final version of the video rather than trying to nudge timecodes by hand.
If the entire track is offset by a constant amount, Subtitle Edit and similar tools have a "shift all times" function that fixes it in one operation.
Step 5: Set sharing permissions so other people can see the captions
This is where most Drive caption setups quietly fail. A caption track is a separate file, and Drive permissions apply per file.
If you share the video with your team but leave the SRT restricted, your viewers will open the video and see no captions, or see the CC button do nothing. There is no warning telling you this has happened.
To avoid it:
- Select both the video file and the caption file.
- Right click and choose Share.
- Give the same audience at least Viewer access to both.
- If the files live in a shared folder, confirm the folder's sharing settings cover both files, and that neither has an overriding restricted permission from an earlier share.
The simplest reliable pattern is to keep the video and its caption file in one folder and share the folder, not the individual files. In Shared drives, membership handles this automatically, which is one good reason to keep captioned assets in a Shared drive rather than a personal My Drive folder.
Step 6: Re-attach captions after replacing the video
Here is the behaviour that catches everyone. Caption tracks are attached to a specific file. If you delete the video and upload a new version, the new upload is a different file with a different ID, and it has no caption track. The old association is gone even though the SRT is still sitting in the same folder.
Two ways to handle it:
Manage versions instead of re-uploading. Right click the video in Drive, choose Manage versions, and upload the new cut as a new version of the existing file. The file keeps its ID, its sharing links, and in most cases its caption association. Note that if you re-cut the video, the old captions will no longer line up, so you still need a fresh SRT.
Re-attach manually. If you did upload a fresh file, just repeat Step 3. It takes under a minute once you know where the menu is.
Either way, treat "re-attach or re-export captions" as part of your checklist whenever you replace a video, in the same way you would re-check a share link.
Common problems and how to fix them
The Captions option is missing from the gear menu. The video is not playing in Drive's native player, or the format is unsupported. Re-encode to MP4 (H.264 and AAC) and open the file by double clicking it in Drive.
Drive rejects the caption file. Check the extension is genuinely .srt or .vtt and not .srt.txt. Also check the file is plain text with UTF-8 encoding. Files saved as UTF-16 or with a Windows BOM sometimes fail to parse.
Captions show as garbled characters. Almost always an encoding problem. Re-save the SRT as UTF-8 in your text editor or subtitle tool.
Viewers say they cannot see captions but you can. Permissions. See Step 5. You are seeing the track because you own both files.
Captions vanished after re-upload. Expected behaviour, not a bug. See Step 6.
Captions work in Drive but not when embedded elsewhere. Drive's caption tracks belong to Drive's player. If you embed the video in a site, an LMS, or a slide deck, the track usually does not travel. For anything public facing, upload to a platform that carries its own subtitle support, or burn the captions into the video. The same principle applies on social platforms, which each handle subtitle files differently; see our guides to captions on LinkedIn videos and captions on Facebook videos.
Should you use a caption track or burn captions into the video?
Caption tracks are the better default for internal Drive content. They are editable, searchable by the viewer, and can be toggled off. If you spot a typo, you fix the SRT rather than re-rendering the video.
Burned in captions (also called open captions) make sense when the video will travel outside Drive, get downloaded, or be posted to a feed where playback is silent by default and you cannot rely on the viewer switching captions on. Short vertical content is the clearest example, which is why the workflow for captions on TikTok and Instagram Reels looks quite different from this one.
A practical compromise: keep a clean SRT as the source of truth, use it as a Drive caption track for the internal version, and burn it in only for the versions that leave Drive.
Frequently Asked Questions
Can Google Drive generate captions automatically?
No. Drive plays caption files but does not create them, so you need to produce an SRT or VTT elsewhere and attach it. Google Slides has a live captioning feature during presentations, and Google Meet captions recorded calls, but neither writes a subtitle file you can attach to a Drive video. You will need a transcription tool, a manual pass, or an export from another platform.
What caption file formats does Google Drive support?
Drive's video player accepts SubRip (.srt) and WebVTT (.vtt) files. Both are plain text with timecodes, and most transcription and subtitle tools export either one. Save the file as UTF-8 and confirm the extension has not been changed to .txt by your text editor.
Why do my captions disappear when I replace the video in Drive?
Caption tracks are linked to a specific file ID, not to a filename or folder. Deleting a video and uploading a replacement creates a new file with a new ID, so the caption association is lost. Use Manage versions to upload a new cut of an existing file, or simply re-attach the caption track through the player's settings menu.
Do viewers need edit access to see the captions?
No, Viewer access is enough, but they need it on the caption file as well as the video. If the SRT is restricted while the video is shared, viewers get a video with no working captions and no error message explaining why. Sharing the containing folder, or keeping both files in a Shared drive, avoids the problem entirely.
Once you have done this once, it takes about two minutes per video: export the SRT, drop both files in the same shared folder, attach the track in the player's settings, and check the CC button works from a colleague's account rather than your own. The part worth building a habit around is the SRT itself, because a clean, accurate caption file is the asset you reuse everywhere else, whether the video ends up in Drive, on a landing page, or in a feed.
