How to add subtitles to mp4
- 1
Upload your MP4
Drag your MP4 directly into CentClip - no account, no credit card, and no software to install. Your first 5 minutes are processed free so you can judge quality on a real clip before spending anything. Files are handled securely in your browser session and not stored after processing completes.

Review and edit your subtitle lines
CentClip opens a time-synced editor where every subtitle block sits next to its start and end timestamp. Scan through to fix proper nouns, technical terms, or any words the recognizer clipped - edits apply immediately before export. CentClip supports 50-plus spoken languages, so you can subtitle an MP4 in Spanish, French, Portuguese, Japanese, or dozens of others at the same flat rate.

Download your subtitled MP4, SRT, or VTT file
Burn the subtitles permanently into a new MP4 so they appear on every device and platform without requiring a companion file. Or download a standalone SRT or VTT to upload alongside your original on YouTube, Vimeo, or an LMS. A plain text transcript is also available on the same screen if you need the words without timecodes.
Why choose CentClip?
Burned-in subtitles travel with the video no matter where it lands
Separate SRT files get stripped by social platforms, forgotten in email threads, or simply never switched on by viewers. Burning subtitles into the MP4 means everyone who watches - on Instagram, a company intranet, a smart TV, or a phone - sees them automatically. CentClip renders the subtitle text frame-accurately so it never drifts out of sync with the speaker, even on clips with lots of cuts. The result is a single self-contained MP4 you can hand off without worrying about companion files.
Pay per minute instead of per month
Subscription captioning tools charge a flat monthly fee whether you subtitle one video or fifty. CentClip charges 5 cents per minute, so a 10-minute interview costs 50 cents and a 45-minute webinar costs $2.25 - nothing more. There is no plan to choose, no seat limit, and no annual commitment that locks you in. Credits never expire, so a $10 top-up today covers the MP4 sitting in your queue next month.
Subtitles in the spoken language, not a translated guess
If your MP4 was recorded in a language other than English, you need subtitles that match what was actually said - not a machine translation that introduces new errors. CentClip transcribes the spoken language directly, covering 50-plus languages at the standard 5-cent-per-minute rate with no premium language tier. This makes it straightforward to subtitle multilingual training recordings, international conference sessions, or customer interviews in their original language. The editor flags low-confidence words so you know exactly where to double-check before you export.
FAQ
How accurate are the subtitles CentClip adds to my MP4?
Accuracy is highest with clear audio and minimal background noise - most clean recordings come back needing only minor corrections. The built-in editor lets you review and fix every subtitle line before you export, so the final MP4 reflects exactly what you approve.
Is there a free trial, and what does it cost after that?
Yes - your first 5 minutes are completely free with no account and no credit card required. After that, adding subtitles to an MP4 costs 5 cents per minute with no subscription; you buy credits when you need them.
What formats does CentClip accept and export for MP4 subtitles?
CentClip accepts MP4 uploads and exports a burned-in MP4, a standalone SRT, a VTT file, or a plain text transcript - all compatible with YouTube, Vimeo, TikTok, and any platform that supports standard subtitle formats.
Do my credits expire if I don't use them straight away?
No - CentClip credits never expire. Buy a batch for your current project and use whatever is left on the next one, with no monthly reset or subscription deadline to worry about.
