Step 1 — CapCut Auto Captions (Easiest)
- Import your video into CapCut
- Click Text → Auto Captions
- Pick language (Hindi, English, etc.)
- AI transcribes and times everything automatically
- Style the captions — font, color, size, position
- Export with burned-in captions OR download .srt
Step 2 — Style Captions for Shorts
For Shorts/Reels the caption style matters:
- Big, bold text — readable on small screens
- Keyword highlighting — important words in different color
- 1-2 lines at a time — word-by-word style is trending
- Centered or bottom — where eyes naturally go
Step 3 — YouTube Auto-Captions
- Upload video → YouTube auto-generates captions (in supported languages)
- Go to YouTube Studio → video → Subtitles
- Review and fix — auto-captions have errors, edit them
- Publish
Step 4 — The Accuracy Check
Auto-captions aren't perfect:
- Hindi names/words often mishear
- Technical terms get garbled
- ALWAYS review before publishing
Fix errors in CapCut (tap any caption to edit) or YouTube Studio.
The Most Accurate Free Option (Advanced)
OpenAI Whisper (free, open-source) is the most accurate AI transcription — you can run it via tools like Subtitle Edit or online Whisper tools. For critical projects, it's the gold standard.
