Win the Viewers Who Watch on Mute

Most apps play videos with the sound off, so a video without captions is silent when someone first sees it. That is the exact moment they choose to keep watching or scroll away. Captions give them something to read straight away, even in a noisy place.

Add Subtitles to YouTube Videos FAQs

How accurate are the subtitles?
99% accurate on every video you upload. Fast talkers, regional accents, background noise and an imperfect mic are all handled.
Which languages can it subtitle?
More than 99, including English, Spanish, Hindi, Japanese, Arabic, Portuguese and Mandarin. Your subtitles come back in the same language you spoke.
Is this better than YouTube's automatic captions?
Yes. You get 99% accuracy on real-world audio, full control of how the text looks, and any word you want to change is one click away.
What if the AI gets a word wrong?
Just click the word and retype it. Subtitles work like a text document, so a product name or an unusual spelling is fixed without disturbing the timing around it.
Will viewers see the subtitles without turning captions on?
Yes. Your subtitles sit inside the video itself itself, so they are on screen for everyone from the first frame, on every player and every device.
Do I need to add the subtitles again if I re-cut the video?
No. The text lives in the frames, so any clip you pull out of a long video keeps its subtitles exactly as they were.
Can I change the font, color and position?
Absolutely. Font, color, stroke, shadow, position and scale are all yours to adjust, and you can start from any of our 20+ styles used by top creators.
What video files can I upload?
MP4, MOV, WEBM and M4V are all supported. Just drag your file in and the subtitles start straight away.
Do exports have a watermark?
Never, on any plan. Free accounts export subtitled videos at full quality, with no watermark added anywhere on the frame.
Is there a free plan?
Yes, and it comes with generous free usage, unlimited downloads and no watermark. Paid plans give you more credits, and they work across every tool in Eliro.
