A subtitle file that comes back with its timings shifted is worse than one that was never translated, and that is exactly what happens when you paste one into a translation box: the model helpfully reformats the numbers. Here the timestamps, cue indexes and cue settings are copied through untouched and only the caption text is sent. What comes back is re-wrapped to about forty characters a line, the width players, YouTube and broadcasters expect, so it does not run off the screen.
SRT and WebVTT are the two subtitle formats everything reads: video players, YouTube, Vimeo, editing software, broadcast systems and every social platform that accepts captions. Both are plain text — a timestamp, then the words shown while it runs — which is why they are trivially editable and why a translated subtitle file drops straight back into the same video.
Paste a subtitle file into a translation box and watch what happens to it. The model sees 00:01:23,400 --> 00:01:26,120, decides it is text, and helpfully tidies it — a comma becomes a full stop, a leading zero disappears, an arrow becomes a dash. The captions are now in the right language and the wrong places, which is worse than not translating them at all, because a viewer can ignore a foreign subtitle and cannot ignore one that arrives two seconds late for the rest of the film.
So the timing never goes anywhere near the translator. The file is split first: cue numbers, timestamps, WebVTT cue settings and blank lines are copied through character for character, and only the caption text is sent. Whatever comes back cannot move a timing, because the timings were never part of the request.
A cue is usually broken across two lines to fit comfortably at the bottom of the frame, and the break is placed for the original wording. Translated text is a different length, so keeping the original break would leave one line of two words and one that runs off the edge. The translated cue is re-wrapped at word boundaries to about forty characters a line — the convention players, broadcasters and subtitle guidelines all settle around. Line breaks within a cue therefore will not fall where they did in the original; the cue as a whole appears and disappears at exactly the same moment.
SubRip (.srt) and WebVTT (.vtt) between them cover almost everything that reads captions: YouTube, Vimeo, video editors, media players, and the social platforms that accept subtitle uploads. The file comes back in the format it went in, so it drops straight back onto the same video without a conversion step in between.
Cues are short and often mid-sentence, which is the hardest case for machine translation — a line with three words in it has almost no context to work from, and dialogue is idiomatic by nature. This is a good way to make a video watchable in a language you do not speak, and not a substitute for a subtitler on anything published commercially. Formatting tags inside a cue may not survive the round trip intact.
Yes — there is no sign-up, payment or watermark. Server-processed tools use the published file-size, duration and fair-use limits so jobs remain available to everyone; those are technical safeguards, not a paid tier.
Yes. Drop in as many as you like and each is translated in sequence with its own progress status, then downloaded individually or all together as a ZIP. Long files are sent for translation in batches, so a stack of large documents can reach the fair-use ceiling — if it does, the message says so and waiting a few minutes is all it takes.
Yes — this tool needs a full office engine, so your file is sent to our server over an encrypted (HTTPS) connection, converted there, and deleted immediately after the PDF is delivered. It is never read for any other purpose, never shared, and never stored. Files up to 50 MB are accepted.
SubRip (.srt) and WebVTT (.vtt), which between them cover almost everything: YouTube, Vimeo, video editors, media players and social platforms all read one or the other. The file comes back in the same format it went in. Timecodes, cue numbers and WebVTT cue settings are copied through character for character, so the result drops straight back onto the same video.
