Video to Subtitles
85% of social videos are watched with the sound off. Without subtitles, you're losing most of your potential viewers. Get the transcript, format it as captions, and make your videos work without audio.

Subtitles are no longer just an accessibility feature — they are a watch-time optimization strategy. Studies consistently show that videos with captions get 40% more views and significantly longer watch sessions. The reason is simple: people watch videos in environments where audio isn't possible — commuting, at work, in bed — and they keep watching if subtitles are available. Without them, they scroll away in the first two seconds. Beyond engagement, subtitles serve a critical accessibility function for the 1.5 billion people worldwide with some form of hearing loss. For creators, the subtitle workflow is: get an accurate transcript (the hardest part), format it with timestamps, and either upload as an SRT file or burn the captions directly into the video. TranscribeVideo.ai handles the first step — producing the accurate text you need.

Frequently Asked Questions
What's the fastest way to add subtitles to a video?
The fastest end-to-end workflow: (1) get the transcript from TranscribeVideo.ai, (2) paste it into CapCut's auto-caption editor or Kapwing's subtitle tool, (3) the tool auto-aligns text to the audio, (4) export with captions burned in or as an SRT file. For social media, CapCut's mobile app handles the whole process in under 5 minutes.
What's the difference between subtitles and closed captions?
Subtitles transcribe the spoken dialogue only. Closed captions (CC) include subtitles plus audio descriptions for sounds: [music], [applause], [door slams]. For most creator content, subtitles are sufficient. For full accessibility compliance (common in corporate and educational content), closed captions that describe relevant sounds are the standard.
Can I burn subtitles directly into the video?
Yes — burning (or 'hardcoding') captions into the video means they appear on every platform regardless of caption support. Use CapCut, Premiere Pro, or DaVinci Resolve to add captions from your SRT or transcript and export the video with captions baked in. The downside is viewers can't turn them off; the upside is they show everywhere.
Does adding subtitles affect video file size?
An SRT file uploaded separately adds no size to the video — it's just a small text file. Burned-in captions add minimal size since they don't change the video's resolution or bitrate meaningfully. Either way, the impact on file size is negligible.
How accurate is AI transcription for subtitle generation?
On clear speech with no background music, accuracy is typically 95%+. This is good enough for subtitles with minimal editing. On heavy accents, fast speech, or video with background music, you'll need to spend 5–10 minutes reviewing and correcting the transcript before using it as subtitle text.
