To auto generate subtitles, you let speech recognition write them from the video's audio, then check the draft before anyone sees it. Every tool follows the same four steps: tell it the spoken language, press generate, fix the words it got wrong, then publish or export. What changes from tool to tool is where the button lives and what you get at the end: a caption track viewers switch on, or text burned into the picture.
Pick the tool by where the video is going. If it is a YouTube upload, YouTube makes the subtitles for you. If you are already editing in Premiere Pro, DaVinci Resolve or CapCut, use the editor's own feature. If you just want an MP4 with captions on it for Shorts, Reels or TikTok, a web tool is the shortest route. An online subtitle generator runs in the browser, so there is nothing to install. The steps below were checked against each company's own help pages on 21 October 2026.

Before you start
Three things decide how good the first draft is, in any tool.
- Set the language yourself. Some tools guess it. When the guess is wrong, the draft is unusable, so choose it whenever you can.
- Give it clean speech. Music under the voice, two people talking at once and a long silent intro all make recognition worse.
- Know which output you need. A caption track is good for accessibility on YouTube. Burned-in captions are what short-form viewers see with the sound off.
How to auto generate subtitles on YouTube
You do not have to switch anything on. YouTube's help page on automatic captioning says it "can use speech recognition technology to automatically create captions", and that when they are available they are published on the video automatically. As of 21 October 2026, the page lists 67 languages for long-form videos and Shorts, and English only for live streams.
- Upload the video and make sure its language is set correctly in the video's details.
- Wait. YouTube says captions "may not be ready at the time that you upload a video."
- In YouTube Studio, open Subtitles, select the video and click More next to the automatic track to review it.
- To fix lines, open Edit, choose Duplicate and edit, correct the text, then click Publish. YouTube saves your fixes as a new track.
Language settings, auto-translate for viewers and what to do when the CC button never shows up are covered in does YouTube auto generate subtitles.
How to auto generate subtitles in Premiere Pro
Premiere calls this Speech to Text. Per Adobe's help pages (updated 2 June 2026 and 7 January 2026), it works in two stages: make a transcript, then turn it into captions.
- Select Window > Text and open the Transcript tab.
- Click the icon in the tab and choose Generate static transcript.
- Pick the Language (download the language pack if Premiere asks), choose whether to label speakers, then click Transcribe.
- Switch to Window > Workspaces > Captions and Graphics and choose Captions > Create captions from transcript.
- In the dialog, pick a caption preset (Subtitle default suits most videos), the maximum length and the number of lines.
Adobe also suggests ticking Automatic Transcription when you import media, so the transcript is ready before you need it. For styling, burn-in and export options, see how to add captions in Premiere Pro.
How to auto generate subtitles in DaVinci Resolve
The feature is called Create Subtitles from Audio, and Blackmagic's DaVinci Resolve 21 manual (July 2026) labels it "Studio Version Only". The free version of Resolve does not have it. On 21 October 2026, Blackmagic's product page listed Resolve Studio at $236, shown as down from $295.
- Open the timeline on the Edit page.
- Set an In and Out range if you want subtitles for part of the timeline; leave it blank for the whole thing.
- Choose Timeline > AI Tools > Create Subtitles from Audio.
- Set Language (Auto lets Resolve detect it), a caption preset, the maximum characters per line, one or two lines, and the gap between subtitles.
- Click Create. Resolve adds a subtitle track if there is none, and writes to the highest one if there are several.
If you only have the free version, how to add subtitles in DaVinci Resolve covers manual subtitle tracks, importing an SRT and other workarounds.
How to auto generate subtitles in CapCut
CapCut's help center (30 January 2026) calls the feature Auto Captions, also "Recognise Subtitles", and documents it on the web, desktop and phone versions:
- Web: click Captions on the left panel, then Auto Captions, then Recognise, choose the language and click Generate.
- Desktop: click Captions in the left toolbar, then Auto Captions, select the audio source and language, then Generate.
- Phone: tap Captions in the bottom menu, then Auto Captions, confirm the language and tap Generate.
On price, CapCut's own pages are the reference. Its Standard vs Pro article (2 April 2026) lists auto captions among Pro's "Advanced AI tools", and a 3 April 2026 article says a Standard user who sees a Pro prompt has usually used a feature "such as auto captions" that includes Pro-only functionality, and that exporting with Pro features needs Pro. We read these pages through a proxy render, because capcut.com blocks requests from India. Step-by-step fixes for CapCut captions are in how to add subtitles in CapCut.
How to auto generate subtitles on Instagram and in Edits
Instagram has two routes, both in the phone apps.
- Captions sticker. After you select the video or reel to upload, tap Stickers, then Captions. Instagram's help center says it "uses speech recognition technology to automatically create captions", and notes that captions "may not be available to everyone".
- Closed captions on a reel you already posted. Tap Options, then Manage, Edit, Advanced settings, and switch Enable closed captions on or off.
- Edits app. Instagram's Edits help page says to open a project and tap Captions, choose the spoken language, a style and transcription controls (punctuation, title case, whether to show curse words), then tap Generate Captions. Afterwards you can change the style, edit the text, adjust opacity and move the captions.
Edits is free on the App Store, listed by Instagram, Inc. If the sticker's words come out wrong, can you edit auto generated captions on Instagram explains what you can change before and after posting.
How to auto generate subtitles online with CapsAI
A web tool skips the editing software. You upload the finished video and download a copy with the captions burned in, ready to post anywhere. With the CapsAI auto subtitle generator it works like this:
- Upload an MP4 or MOV, up to 10 minutes long. 3 free minutes to start. Files up to 500 MB, or 10 GB with a pack. Videos up to 10 minutes each.
- Choose the spoken language. There are 11: English, Hinglish (Hindi and English mixed, written in Roman script), Hindi, Bengali, Telugu, Marathi, Tamil, Urdu, Gujarati, Kannada and Punjabi. CapsAI does not detect the language for you, so pick the one spoken.
- Generate, then read the draft. Fix any word and its timing in the browser editor.
- Pick one of 37 caption styles (8 free, 29 more with any pack) and set the size and position.
- Export an MP4 with the captions burned in.
Be clear on the limits. CapsAI does not export SRT, VTT or other subtitle files, does not translate, and does not take a YouTube or other link: you upload the file. If you need a sidecar subtitle file, use YouTube, Premiere, Resolve or CapCut instead. Packs are paid once, from $4 (₹49 in India, €4 in the euro area), and watermark-free export comes with every paid pack.
Check the draft before you publish
Auto subtitles are a first draft in every tool above. Play the video once with captions on and look for:
- names, brands and places, which recognizers swap for common words
- numbers, especially fifteen and fifty
- words that appear over music or silence when nobody is speaking
- lines that stay on screen after the speaker stops
Which route fits
- A normal YouTube upload: let YouTube generate the track and review it in Studio.
- You already edit in Premiere or Resolve Studio: use Speech to Text or Create Subtitles from Audio, then burn in or export a file.
- You edit on a phone: CapCut or Edits, checking CapCut's Pro terms first.
- You just need captions on a short clip: upload it to a web tool such as the video subtitle generator and download the captioned MP4.
What to do next
If the video is already finished and you want captions burned into it, try a short clip on the auto subtitle generator with your 3 free minutes and read the draft before you export.
