    Manual Timing Required

    When converting plain text to SRT:

    • You need to add timing manually
    • Or estimate based on text length
    • Best to extract with timing intact

    YouTube often provides VTT format. Convert to SRT:

    Using ffmpeg

    ffmpeg -i subtitles.vtt subtitles.srt

    Using Python

    import webvtt
    
    vtt = webvtt.read('subtitles.vtt')
    srt_content = ""
    
    for i, caption in enumerate(vtt, 1):
        start = caption.start.replace('.', ',')
        end = caption.end.replace('.', ',')
        srt_content += f"{i}\n{start} --> {end}\n{caption.text}\n\n"
    
    with open('subtitles.srt', 'w') as f:
        f.write(srt_content)

    Online VTT to SRT

    1. 1.Download VTT from YouTube
    2. 2.Upload to converter (GoTranscript, Rev)
    3. 3.Download SRT output

    SRT Formatting Tips

    Line Length

    Keep lines readable:

    GOOD:
    1
    00:00:00,000 --> 00:00:03,000
    This is a good caption length
    for easy reading.
    
    BAD:
    1
    00:00:00,000 --> 00:00:03,000
    This is way too long of a caption that will be difficult to read quickly while also watching the video content.
    Best practice
    42 characters per line max, 2 lines max per caption.

    Reading Speed

    DurationMax CharactersWords
    1 second~15 characters~3 words
    2 seconds~30 characters~6 words
    3 seconds~45 characters~9 words

    Timing Overlap

    Avoid overlapping captions:

    WRONG:
    1
    00:00:00,000 --> 00:00:03,500
    First caption
    
    2
    00:00:03,000 --> 00:00:06,000
    Second caption (overlaps!)
    
    CORRECT:
    1
    00:00:00,000 --> 00:00:03,000
    First caption
    
    2
    00:00:03,100 --> 00:00:06,000
    Second caption

    Editing SRT Files

    Text Editors

    Any plain text editor works:

    • Notepad (Windows)
    • TextEdit (Mac)
    • VS Code
    • Sublime Text

    Common Edits

    Fix timing:

    # Shift all captions +2 seconds
    00:00:05,000 --> 00:00:08,000
    becomes
    00:00:07,000 --> 00:00:10,000

    Fix text:

    # Correct errors
    "elan musk" → "Elon Musk"

    Split long captions:

    # Before
    1
    00:00:00,000 --> 00:00:06,000
    This is a very long caption that should be split into two separate captions for better readability.
    
    # After
    1
    00:00:00,000 --> 00:00:03,000
    This is a very long caption that
    should be split into two
    
    2
    00:00:03,000 --> 00:00:06,000
    separate captions for
    better readability.

    • Social media uploads
    • Simple subtitle needs

    When to Use Other Formats

    • VTT: Web embedding with styling
    • ASS: Complex positioning/effects
    • TTML: Broadcast requirements

    Frequently Asked Questions

    Q1What's the difference between SRT and VTT?
    SRT uses commas in timestamps (00:00:00,000) and simpler formatting. VTT uses periods (00:00:00.000) and supports additional styling. Most software accepts both, but SRT has broader compatibility.
    Q2Can I edit the SRT file in any text editor?
    Yes. SRT files are plain text. Open in Notepad, TextEdit, or any text editor. Just maintain the format: sequence number, timecode, text, blank line.
    Q3Why are my SRT timestamps slightly off?
    YouTube's auto-captions aren't perfectly timed. Use subtitle editing software to adjust timing, or accept small variations for non-professional use.
    Q4How do I add SRT subtitles to my YouTube video?
    In YouTube Studio, go to your video → Subtitles → Add → Upload file → Select SRT. YouTube will sync the subtitles to your video.
    Q5Can I convert YouTube's auto-captions to SRT?
    Yes. Use NoteLM.ai's "Download SRT" feature, or yt-dlp with the --sub-format srt option. Both extract YouTube's captions in SRT format.
