YouTube Subtitle Editor — Boost Watch Time & SEO
YouTube viewers who watch without sound skip videos without captions. CutSnap transcribes your YouTube content automatically, lets you style captions to match your channel brand, and exports both a burned-in MP4 and a separate SRT file for YouTube Studio.
How It Works
Add YouTube Captions in 3 Steps
Upload Your Video
Drop your 16:9 or 9:16 (Shorts) video file. CutSnap starts AI transcription immediately.
Edit & Style Captions
Fix any errors in the live editor. Apply a saved Style Profile or customise the caption design for YouTube.
Export for YouTube
Download the captioned MP4 ready to post on YouTube, plus an SRT file for any platform that accepts caption tracks.
Pro Tips
YouTube Caption Best Practices
Upload burned-in + SRT for maximum SEO
YouTube's crawler cannot read burned-in text. Upload the captioned MP4 for visual quality AND the SRT file as a closed-caption track in YouTube Studio to index the text for search.
Keep lines under 42 characters for mobile
YouTube's mobile player clips wide captions. CutSnap's editor shows a mobile-width preview so you can catch overflows before export.
Captions improve watch time by signalling value
Captions help viewers understand the topic immediately and decide to keep watching. They also help non-native speakers follow along without pausing.
FAQ
Should I use burned-in captions or YouTube's auto-captions?
Use both. Burned-in captions appear for all viewers immediately. Then upload an accurate SRT file as a closed-caption track in YouTube Studio so viewers can toggle them and so YouTube can index the text for SEO.
Does CutSnap export SRT files for YouTube Studio?
Yes. Every CutSnap project exports both a burned-in MP4 and a standalone SRT file. Upload the SRT in YouTube Studio under Subtitles for your video.
Does CutSnap support YouTube Shorts (9:16)?
Yes. CutSnap handles any aspect ratio. Upload a vertical Shorts video and the captions are positioned correctly.
