Transcription

Use OpenAI Whisper model for speech to text conversion:

bash

whisper video.mp4 --model medium --language zh --output_format json

Model	Use Case
`medium`	Default, balances speed and accuracy
`large-v3`	High precision, slower

The output JSON contains word-level timestamps for subsequent SRT generation.

One line per screen	No line breaks, no stacking

No punctuation at the end of sentences	`Hello` instead of `Hello.`
Punctuation is retained within sentences	`Click here first, then click there`

Subtitle Draft Format

What I send to users (plain text, ≤15 characters per line):

Today I will share a tip with you
Many people may not know
Actually this feature
Is hidden in settings
You just need to click here
And you will see it

Users send back the modified text to me, then I match timestamps to generate SRT.

Style

Default: 24pt white text, black stroke, bottom centered

Optional styles:

Style	Description
Default	White text with black border
Yellow text	Yellow text with black border (eye-catching)

Users can request:

"Larger font" → 32pt
"Put on top" → Top centered
"Yellow subtitles" → Yellow text with black border

Output

01-xxx_subtitle_draft.txt   # Plain text, for user editing
01-xxx.srt          # Subtitle file
01-xxx-with_subtitles.mp4     # Video with embedded subtitles
