How to generate automatic subtitles for a video

1

Upload the video

Drag the file (MP4, MOV, MKV, WebM…) or click to choose it. Free: up to 10 minutes per video; Pro: up to 2 hours.

2

Pick the spoken language

Leave it on "Detect automatically" or choose English, Portuguese, or Spanish. Sign in with your email and the 6-digit code you receive. No password.

3

Wait for the captions

Our transcription engine listens to the audio and splits the text into short blocks, each with its start and end time.

4

Download the .srt or .vtt

Click Download .srt (video editors and YouTube) or Download .vtt (web players). The flowing text is also available to copy.

What it's for

Reels, TikTok, and Shorts

Most people watch on mute. Generate the .srt, import it into CapCut, style it, and export with the captions burned into the video.

YouTube

Upload the subtitle file in YouTube Studio: the video becomes searchable and gains automatic translation and accessibility without re-uploading anything.

Online courses and classes

Course platforms accept VTT or SRT next to the video. Students follow along by reading and find the passage they are looking for.

Corporate videos

Training, internal announcements, product videos: captions meet accessibility requirements and work on the lobby screen, on mute.

Frequently asked questions

What is the difference between SRT and VTT subtitles?

Both carry the same text with the same timing. .srt is the format most widely accepted by video editors (CapCut, Premiere, DaVinci) and by YouTube. .vtt is the standard for web video players (the HTML video tag, course platform players). Download both: it costs nothing.

How do I import the SRT subtitles into CapCut?

In CapCut for desktop, put the video on the timeline, open the Text tab, go to Local captions, and click Import; pick the .srt you downloaded here. The captions come in synced and you choose font, color, and position before exporting. On mobile, the path is Text, then Captions; the import option depends on the app version.

How do I import the subtitles into Premiere Pro?

Use File > Import and select the .srt; it shows up in the project panel. Drag it onto the timeline above the video and Premiere creates a caption track. To fix a line, open Window > Text. On export, you choose to burn the captions into the video or generate a separate sidecar file.

How do I upload the subtitles to YouTube Studio?

In YouTube Studio, open Content, click the video, and go to Subtitles. Add the language, click Add, and choose Upload file, with timing. Upload the .srt and publish. The subtitles you upload replace YouTube's automatic ones.

How do I add captions on Instagram or TikTok?

Instagram and TikTok do not import subtitle files. The way to go is to burn the captions into the video before posting: import the .srt into CapCut (or the editor you use), adjust the look, and export. That way the captions look the same on every network and nobody depends on the app's automatic captions.

Do the subtitles come synced? Can I fix them?

Yes, each block has the start and end time of the line. To fix a word, edit it in your video editor or open the .srt in any text editor: it is plain text. Note: editing the flowing text on screen does not change the .srt, which is generated from the server's original transcription.

What are the duration and size limits for the video?

On the free plan, 2 videos per account, up to 10 minutes each. If the video is longer, we generate captions for the first 10 minutes and you decide whether you want the rest. With Rollin Ferramentas Pro, videos up to 2 hours with no limit on quantity; the price is in the Pro block on this page. Files up to 1 GB.

Which video formats are accepted? Do I have to pick the language?

MP4, MOV, MKV, WebM, AVI, 3GP, and MPEG, among others. We extract the audio automatically. The language can be detected on its own; if you prefer, choose English, Portuguese, or Spanish. To also get the flowing text of the video, use the transcribe video page; for classes and lectures or recorded meetings (in Portuguese) we have step-by-step pages. The other free tools are in the tools hub.

Is the video stored?

No. We extract only the audio, which is sent encrypted and transcribed by an infrastructure provider contracted by Rollin Host only to produce the captions. The file is deleted right after processing and, in any case, within one day. We never sell or share the content with anyone.

Need volume or a private API?

This tool is free for occasional use. To transcribe at scale, with your own API and no duration limit, we offer a dedicated Whisper Server — audio processed on your infrastructure, nothing sent outside.
