How to Generate an SRT File From Any Video (2026)

If you've ever tried to add subtitles to a video manually, you know how painful it is. Writing timestamps by hand, syncing text to speech, exporting in the right format, it takes hours. The good news: AI tools can now generate a perfectly-timed SRT file from any video in under a minute. Here's exactly how to do it.

What is an SRT File?

An SRT (SubRip Subtitle) file is a plain text document that contains timed subtitles for a video. Each subtitle entry follows a simple structure:

SRT file format example

1 00:00:01,200 --> 00:00:04,500 Hey everyone, welcome back to the channel! 2 00:00:04,800 --> 00:00:08,100 Today we're going to show you how to generate SRT files automatically.

SRT is the most universally supported subtitle format. It works with YouTube, TikTok, Premiere Pro, DaVinci Resolve, CapCut, VLC, and virtually every other video platform and editing tool. If you need subtitles anywhere, SRT is the format to use.

Creating SRT files manually means writing timestamps accurate to the millisecond for every line, a tedious, error-prone process. AI transcription tools eliminate all of that by generating the SRT automatically from the audio track.

How to Import Your SRT Into a Video Editor

Once you have your .srt file, adding it to your video is straightforward in any major editor:

Premiere Pro: File → Import → select your .srt file. Drag it onto the timeline above your video track. The subtitles snap into place automatically.

DaVinci Resolve: In the Edit or Cut page, go to Timeline → Subtitles → Import Subtitle File. Select your .srt and the captions appear as a dedicated subtitle track.

CapCut: Open your project, tap Text → Auto Captions or import the SRT via Add → Subtitles. The app parses the timestamps and places each line correctly.

YouTube: In YouTube Studio, open your video, go to Subtitles, click Add → Upload file, and upload the .srt. YouTube maps each timestamp to the correct frame automatically.

TikTok: TikTok doesn't natively support SRT uploads from the web editor. The recommended workflow is to burn your subtitles into the video before uploading using CapCut or another editor. See our guide: how to add captions to TikTok.

Tips for Better SRT Accuracy

AI transcription is accurate for most content, but a few factors affect the quality of your SRT output:

Clear audio matters most. Background music, overlapping voices, and echo reduce accuracy. If possible, use audio recorded in a quiet environment with a good microphone.
Set the language explicitly. Auto-detect works well but setting the language manually removes any ambiguity, especially for shorter clips.
Use the highest-quality source file. A compressed 128kbps MP3 will produce less accurate results than an original 320kbps file or a lossless WAV.
Review before exporting. Scan the transcript in Dokitscript before downloading the SRT. You can edit individual lines directly in the interface.
