Subtitling Services

Subtitle translation, captioning and SDH for video, delivered as timed SRT or VTT files that drop straight into the platform you publish to.

A subtitle file is read at speed, so the translation has to survive compression: the same meaning in fewer characters, timed to speech that has not moved. We translate and time captions for corporate video, training libraries, advertising and hearing footage, and deliver SRT or VTT ready to upload, from $54 per project.

    Video & Captions

    What a Subtitle File Needs From the Translation

    Speech runs at roughly three words a second and a viewer reads slower than they listen, so the linguist translates for the eye: the meaning of each line survives while the wording is tightened to fit the reading time the timing allows.

    What the Subtitling Covers

    • Timed to the Speech: Each caption is spotted against the original audio, so a line appears when it is spoken rather than when the paragraph begins, and stays on screen long enough to be read.

    • Reading Speed and Line Length: Lines break where a reader's eye expects a pause, and each caption is held to the reading rate the player allows, which is why the wording is often tighter than the transcript.

    • SDH on Request: Captions for deaf and hard-of-hearing viewers add speaker identification and descriptions of meaningful sound, such as a door closing or a phone ringing, alongside the dialogue.

    • Format and Delivery: SRT, VTT and ASS files are all produced, named and timed for the player they will run in, so nothing has to be re-timed after upload.

    Before You Order

    Two things decide how good a subtitle file can be before the translator starts: what you can send alongside the video, and where the video is going.

    • Script or Audio: A script or existing transcript improves both accuracy and speed; without one, the captions are spotted from the audio and checked against the finished cut.

    • Where It Will Play: YouTube, a learning system, a broadcast server and a courtroom display each handle captions differently, and the file is prepared for the one you name.

    • How Many Languages: One master timing can carry several target languages, which keeps a multi-language release in sync and costs less than timing each version from scratch.

    Send the video link, any script or existing captions, and the language pairs you need.

    Prices are per document and start at $54 — see what a translation costs.

    Streamlined Workflow

    How a Subtitled File Is Produced

    Three steps, and the only decision that is awkward to reverse is the format, because the player sets it rather than us.

    Knowledge Base

    Frequently asked questions

    DHCTranslations translates and times captions for corporate video, training libraries, advertising and hearing footage from our New York base. Send the video or a link to it with the language pair, and the quote comes back before any timing starts.

    A short project is charged from $54 at DHCTranslations, and longer footage moves to a per-minute rate once the runtime passes the point where a flat charge stops being the fair way to price it. Additional languages are quoted per language, not per word.

    DHCTranslations usually delivers a five-minute video the next business day when it is confirmed before 4pm ET. A training library of several hours is scheduled with a delivery date, because every video needs its own timing pass.

    SRT and VTT as standard, with ASS where a platform needs styled captions. Name the player or the learning system and the file is produced to what that player accepts, so it loads without conversion.

    Yes. SDH adds speaker labels and descriptions of meaningful sound, which is what makes a recording usable for an audience that cannot hear the cues the dialogue assumes.

    No, but it changes the job. A script or transcript lets the linguist work from text and time against the cut; without one, the speech is transcribed first and the quote reflects that extra pass.

    Yes, and it is the cheaper route once you need more than two. Timing is set once on the master and each language is fitted to it, so every version stays in sync with the same soundtrack.

    Yes, including vertical formats where the safe area is smaller and the line length shorter. Captions are broken for the frame the video is actually watched in, not for a widescreen master.

    No. This service produces text on screen. Voiceover, dubbing and mixing involve casting and studio work, and we will say so rather than quote for something we do not produce in house.

    Over 200 pairs, with the common US requests being Spanish, Chinese, Vietnamese, Tagalog, Arabic, French, Portuguese and Korean. Every target language is handled by a native speaker of it.
