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
Method 4: VTT to SRT Conversion
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)

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.

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
# 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.

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.
