How to translate a video to English online
To translate a video to English, upload an MP4, MOV, or WebM file you own or are authorized to edit. UnmarkAI can detect the source language from 116 options, then create an English-dubbed MP4 and downloadable original SRT, English SRT, and voiceover MP3 files. English (US) is selected by default, and you can switch to English (UK) before starting. If you want captions visible in the final video, enable burned-in English subtitles. Eligible plans can also remove existing hardcoded source captions, preserve background audio, improve output quality, or let you review the transcript manually. Check names, terminology, pronunciation, timing, and subtitle placement before publishing the translated video.

Frequently asked questions
Questions about translating video to English
How can I translate a video to English online?
Upload a local MP4, MOV, or WebM file you own or are authorized to process. Confirm the detected source language, select English (US) or English (UK), review the translation, and export the result.
Does the task create English subtitles as well as dubbing?
Yes. A base video translation creates an English-dubbed MP4 and a downloadable English SRT. You can also burn the English subtitles into the final video if you want visible captions.
What files can I download?
You can download the English-dubbed MP4, the original-language SRT, the translated English SRT, and the English voiceover MP3.
Which formats and file sizes are supported?
Upload MP4, MOV, or WebM files up to 2 GB. The landing page checks the format and size before moving the file into the workbench.
Can I translate a video to English for free?
New accounts receive 10 free points with no credit card required. The workbench displays the estimated point cost before you start; the available video length depends on the task settings.
Can I paste a YouTube URL to translate it?
No. Direct YouTube URL import is currently unavailable. Upload a local file only when you own the video or have permission to translate it, then add the reviewed MP4 or SRT to your own channel.
What if the source video has hardcoded subtitles?
Eligible plans can clean authorized burned-in source captions before English subtitles are added. Review the cleaned frames carefully, especially over movement or detailed backgrounds.
Can I choose US or UK English?
Yes. English (US) is preselected when you enter the workbench, and you can switch to English (UK) before creating the task.
