What is an SRT file?
An SRT (SubRip Subtitle) file is a plain text file with timestamps. Each subtitle is a numbered block:
1
00:00:00,000 --> 00:00:03,500
Hello and welcome to this tutorial.
2
00:00:03,500 --> 00:00:07,200
Today we're going to learn about subtitle files.
Most video editors (Premiere, DaVinci Resolve, Final Cut), video players (VLC, MPV, web players), and platforms (Vimeo, custom HTML5 players) accept SRT directly.
Steps to convert YouTube to SRT
1. Find the YouTube video
Copy the URL of any public YouTube video. SubExtract supports regular videos, Shorts, and live replays.
2. Paste into a transcript extractor
Use a tool that returns SRT output. SubExtract supports SRT export directly — paste the URL, click Extract.
3. Download the SRT file
Click the SRT download button. The output is a .srt file with proper timestamps.
4. Use the SRT file
- Video editor: drag the SRT into your subtitle track
- VLC player: drop the SRT file into the player or place it next to the video file with the same name
- Web player: load via
<track kind="subtitles" srclang="en" src="video.srt"> - Translation: open in a text editor or specialized SRT editor
Auto-generated vs human-uploaded captions
YouTube has two types of captions:
- Auto-generated: Google's speech recognition produces these automatically. Accuracy ~90-95% for clear English audio.
- Human-uploaded: the creator manually added these. Higher accuracy, often includes speaker labels and sound descriptions.
The extraction tool returns whichever exists — both work fine for SRT output.
Common issues
"No captions available" — the video genuinely has no captions in any language. Auto-generation may have failed on poor audio quality.
Timestamps are off — auto-captions occasionally have small drift (within a few hundred milliseconds). For frame-accurate captioning, manual review is required.
Special characters look wrong — make sure to save as UTF-8 encoding. Most tools default to this.
Frequently asked questions
Can I edit the SRT file after download? Yes. SRT is plain text — open in any text editor. Tools like Subtitle Edit or Aegisub provide visual editing with timeline preview.
Does this preserve speaker labels? Only if the source captions include them. Auto-generated captions typically don't have speaker labels.
Can I get SRT in multiple languages? SubExtract returns one language per extraction. For another language, switch the language selector before extracting (Pro users can also translate post-extraction).
Will SRT work in YouTube itself? Yes — you can re-upload an SRT to a YouTube video as the creator. Useful for correcting auto-captions or adding translations.
