How to Transcribe a Video and Generate SRT Subtitles for Free
Manual transcription is slow, and most caption services want a subscription. This guide shows how to turn any video or audio into a full text transcript and a ready-to-use SRT subtitle file with AI, for free, what an SRT actually is, and how to get the captions onto your video.

Why you need a transcript and subtitles
Two facts drive almost every transcription job. First, most social video is watched on mute, so without captions your message simply does not reach scrolling viewers. Second, transcribing by hand is painfully slow, roughly four to six minutes of typing for every minute of audio, and most caption services want a monthly subscription before they hand anything back.
AI collapses that. You give it the file once and get back two things at the same time: a clean text transcript you can paste anywhere, and a timed SRT subtitle file you can drop onto the video.

Open the Transcribe Tool, FreeWhat an SRT file is
SRT stands for SubRip Subtitle, and it is the most universally supported caption format there is. It is just a small text file: each entry has a number, a start and end timecode, and the line of text to show in that window. Because it is plain and standardised, almost everything reads it, from the free VLC player to YouTube, Instagram, Premiere, DaVinci Resolve, and CapCut. That universality is why getting an SRT, rather than captions locked inside one app, is so useful.
How to add the subtitles to your video
There are two routes. For platforms, you upload the SRT next to the video: on YouTube, open the subtitles section and import the SRT, and viewers can toggle captions on. For a permanent burn-in, where the captions are baked into the picture and always visible, load the SRT into a video editor such as Premiere, DaVinci Resolve, or CapCut, which place the timed text onto the footage so it survives re-uploads and works everywhere.
Transcripts beyond captions
The text transcript is worth as much as the subtitles. A podcast episode becomes show notes and a blog post. A recorded meeting becomes searchable minutes. An interview becomes quotable copy without rewinding. And because search engines index text, not speech, publishing the transcript of a video gives that content a way to be found at all. If your source is a video you first need to shrink or convert, the video compressor and video converter handle that in the browser first.
FAQ
How do I transcribe a video for free?
Use the SammaPix Transcribe tool at sammapix.com/tools/transcribe. Add your video or audio file and AI returns a full text transcript plus subtitles in SRT format. It is free to try with no signup, and it is powered by Google Gemini.
What is an SRT file?
SRT, or SubRip Subtitle, is the most widely supported subtitle format. It is a small text file that lists each line of dialogue with a start and end timecode. Almost every video player, editor, and platform, from VLC to YouTube to Premiere, can load an SRT file to display subtitles.
Can I transcribe audio as well as video?
Yes. The tool handles both. You can transcribe a podcast, an interview recording, a voice memo, or a lecture the same way you transcribe a video, and get a clean text transcript back.
How do I add the subtitles to my video?
For online platforms, upload the SRT alongside your video. YouTube, for example, has a subtitles section where you import the SRT. For a permanent burn-in, load the SRT into a video editor such as Premiere, DaVinci Resolve, or CapCut, which place the timed captions onto the footage.
Why add subtitles at all?
Most social video is watched on mute, so captions are often the only way your message lands. They also make content accessible to deaf and hard-of-hearing viewers, help non-native speakers, and give search engines and platforms text to index, which can improve reach.
