FAQ
Frequently asked questions
These are short, direct answers about how XCaptions works: what happens to your video, the clip and file limits, which languages and subtitle formats are supported, how Urdu and Roman Urdu are handled, and what to check before you publish subtitles.
Questions and answers
Is my video uploaded to a server?
No. The video is opened and edited directly in your browser and is never uploaded. When you generate subtitles, only the extracted audio file is sent to a speech-to-text service. When you use Translate, only the caption text is sent. XCaptions does not store either on its server.
What are the limits?
Videos longer than 10 minutes are automatically shortened to the first 10 minutes, and you can choose another part of the original. Files above 500 MB are locally prepared to fit the media size limit; source files above 4096 MB cannot be processed. The audio sent for transcription is split into short chunks (about 120 seconds each). Free provider quotas for transcription and translation may also apply.
Which languages are supported?
The speech-to-text step detects the spoken language automatically and supports many languages, including English, Hindi, Arabic and Urdu. You can then translate captions into English, Urdu (Urdu script), Roman Urdu, Hindi (Devanagari), Roman Hindi or Arabic.
Can it write Roman Urdu?
You can translate captions into natural Roman Urdu. Automatic transcription of Roman Urdu speech is not reliable, because speech recognition expects standard script. The dependable route is to generate subtitles first and then translate them to Roman Urdu, or type the Roman Urdu yourself.
What subtitle formats can I export?
You can download SRT, VTT and plain TXT files (as paragraphs or with timestamps), export the extracted audio, or export a captioned video. Subtitle files apply your trim by default and start at zero, and you can turn that off to export every caption.
What video resolutions can I export?
You can export a captioned video at 480p, 720p, 1080p or the original size, as long as the source is at least that tall. Export is a real re-encode with the captions burned in, so it can be slow; keeping the tab open and in front helps.
Is XCaptions free?
Yes. Using the editor is free and needs no account. Transcription and translation run on a provider free tier, so those steps can have their own usage limits and may occasionally be busy.
How accurate are the subtitles?
Speech recognition is good but not perfect, and translation can make mistakes too. Names, strong accents, music and background noise are the usual problem areas. Always review and edit the captions in the editor before exporting and publishing.
Does it work on a phone?
Yes. XCaptions runs in a modern mobile browser and the layout adapts to small screens. Video export is the heaviest part, so on a phone it can be slow and use a lot of memory. Keep the tab open while it runs.
Do I need an account?
No. There is no sign-up, login or email required. Projects auto-save in your own browser, and XCaptions keeps up to three of them. Clearing your browser storage removes them.
Does it have a silence remover or clip cutter?
Not right now. You can trim the start and end of the clip, and you can split, merge and retime individual captions, but there is no automatic silence detection and no clip splitter in the editor today.
Does it work offline?
Editing, styling, trimming and video export happen in your browser, but generating subtitles and translating need an internet connection because those steps use an online service. Loading the page the first time also needs a connection.
