What we do
Our services
What are video translation services?
Video translation services convert spoken dialogue, on-screen text, and graphics from a source video into a target language using five linked steps: transcription, subtitle translation, voice-over or dubbing, on-screen text localisation, and ISO 17100 quality assurance.
What video translation services do we provide in London and the UK?
We provide six video translation services London and the UK, including time-coded transcription, multilingual subtitle translation, voice-over recording, full lip-sync dubbing, on-screen text localisation, and certified video translation for legal evidence, all under ISO 17100 quality control.
What is the video translation workflow from source file to delivery?
The video translation workflow has 6 stages, including source-file ingestion, time-coded transcription, target-language translation, voice-over or subtitle production, on-screen text re-rendering, and ISO 17100 quality assurance before final delivery in the requested file format.
Which languages do we translate video content into?
We translate video content into 200+ languages, including European pairs such as French, Spanish, Italian, German, and Polish, Asian pairs such as Mandarin, Korean, Japanese, and Hindi, and rare pairs such as Pashto, Tigrinya, and Sorani Kurdish.
How much do video translation services cost in the UK?
Video translation services in the UK cost from £30 per page for subtitle translation under 250 words, from £60 per hour for voice-over studio time, and milestone-priced for full dubbing projects above 10,000 words, with a 20% discount for new clients.
How fast we deliver a translated video
We deliver translated videos same-day for orders placed in London before 11:00 GMT under 1,500 words, within 24 to 48 hours for standard subtitle and voice-over projects, and on agreed milestones for full dubbing projects above 10,000 words, all under ISO 17100 quality control.
Video translation transforms a single source video into a market-ready asset for every language your audience speaks, combining transcription, subtitling, voice-over, dubbing, and on-screen text localisation under one project. Our London team delivers this as a managed workflow under ISO 17100, and this page sits inside our wider Professional Translation Services in London, UK offer.
What video translation services are available in London and the UK?
We provide six video translation services in London and the UK, including time-coded transcription, multilingual subtitle translation, voice-over recording, full lip-sync dubbing, on-screen text localisation, and certified video translation for legal evidence, all under ISO 17100 quality control. Each service is delivered by native linguists with audio-visual experience, not generalists.

What does subtitle translation include?
Subtitle translation includes source-language transcription, time-coded SRT or VTT file creation, target-language translation by native linguists, cultural adaptation of idioms, and burnt-in or closed-caption delivery for platforms such as YouTube, Vimeo, and broadcast television. Our Subtitle Translation Services page covers format options in detail.
- Source audio transcribed with timestamps to the second.
- Captions segmented to reading-speed limits of 17 characters per second.
- Target language translated and culturally adapted by a native linguist.
- SRT, VTT, or SSA file produced — or subtitles burnt into MP4 or MOV.
- Second-linguist review against the source video before sign-off.
How does professional voice-over and dubbing work?
Professional voice-over places a target-language narrator over the original audio at reduced volume, while dubbing replaces the original dialogue entirely with lip-synced target-language performance recorded in a studio by native voice actors. Full details sit on our Voice Over Translation Services page.
When is voice-over the right choice?
Voice-over is the right choice for documentaries, corporate videos, eLearning modules, and news segments where the original speaker’s voice must remain audible for authenticity or evidentiary reasons. The source audio stays present at low level, signalling to the viewer that what they hear in their language is a faithful interpretation, not a re-performance.
When is full dubbing the right choice?
Full dubbing is the right choice for film, broadcast television, children’s content, and marketing campaigns where viewer immersion requires the target-language performance to match lip movements and emotional delivery. Dubbing demands studio recording, character casting, and lip-sync editing — see our Dubbing Services page for the production specification.
What is on-screen text and graphics localisation?
On-screen text and graphics localisation translates titles, lower-thirds, callouts, infographics, and embedded captions within the video itself, re-rendering them in the target language while preserving timing, font, and brand styling. This step is what separates a half-translated video from a fully localised one — viewers in the target market see the brand in their language, not English text floating over translated audio.
Certified video translation use cases and requirements
You need a certified video translation when the footage is submitted as evidence to UK courts, the Home Office, tribunals, or regulators, and the translation must carry a signed statement of accuracy from an ISO 17100 certified provider. Our Certified Translation Services are accepted by Crown Courts, the Home Office, immigration tribunals, employers, and regulators.
- UK courts — Crown Court, County Court, Magistrates’ Court.
- Home Office — asylum and immigration submissions.
- Tribunals — employment, immigration, social entitlement.
- Regulators — FCA, GMC, SRA, professional bodies.
- Employers — DBS-adjacent vetting and HR submissions.
How it works
What is the video translation workflow from source file to delivery?
1
Step 1 — How do we ingest your source video file?
We ingest source video files in MP4, MOV, AVI, MKV, WMV, and broadcast formats up to 50 GB through a secure UK-hosted upload portal, with NDA cover applied before any linguist receives the file. Files stay on UK servers under GDPR-compliant handling, and named project managers act as the single point of contact throughout.
2
Step 2 — How do we produce a time-coded transcript?
We produce a time-coded transcript by combining speech-to-text software with native-speaker review, capturing speaker labels, timestamps to the second, and verbatim or clean-read formatting depending on the downstream use case. This stage links to our standalone Transcription Services for clients who need transcripts alone.
3
Step 3 — How do native linguists translate the script?
Native linguists translate the script into the target language using subject-matter specialists for legal, medical, technical, or marketing content, applying translation memory tools to keep terminology consistent across long-running video series. Translation memory matters most for episodic content, course series, and multi-quarter marketing campaigns where the same product names and slogans recur.
4
Step 4 — How do we produce subtitles, voice-over, or dubbing?
We produce subtitles as SRT, VTT, or burnt-in MP4 files, voice-overs as broadcast-quality WAV recordings, and dubbing as lip-synced studio sessions performed by native voice actors briefed on tone, pace, and character. Each production track follows the brief signed off at quote stage, so the delivered asset matches what was scoped.
5
Step 5 — How do we run ISO 17100 quality assurance?
We run ISO 17100 quality assurance through a two-linguist model where a second native reviewer checks accuracy, terminology, timing, and cultural appropriateness against the source video before final sign-off. The standard requires documented terminology management, project records, and corrective-action procedures — full detail sits on our ISO 17100 Certification page.
- First native translator delivers the target-language script.
- Second independent native linguist reviews against the source video.
- Project manager runs a terminology and consistency sweep.
- Technical QA verifies timing, file format, and burnt-in rendering.
- Client receives a delivery note with sign-off ready.
Which languages can video content be translated into?
We translate video content into 200+ languages, including European pairs such as French, Spanish, Italian, German, and Polish, Asian pairs such as Mandarin, Korean, Japanese, and Hindi, and rare pairs such as Pashto, Tigrinya, and Sorani Kurdish. Coverage is benchmarked above the 80 to 100 language range typical of UK competitors.
| Region | Sample pairs | Voice talent base |
|---|---|---|
| Europe | French, Spanish, Italian, German, Polish | In-country native actors |
| Asia | Mandarin, Cantonese, Korean, Japanese, Hindi | In-country and UK diaspora |
| Middle East | Arabic, Farsi, Hebrew, Turkish, Pashto | RTL subtitle rendering supported |
| Africa | Swahili, Amharic, Tigrinya, Yoruba, Somali | UK diaspora and in-country |
| Rare pairs | Sorani Kurdish, Kurmanji Kurdish, Dari | Vetted specialist network |
Which European languages do we cover?
European languages we cover include French, Spanish, Italian, German, Portuguese, Polish, Romanian, Bulgarian, Russian, Ukrainian, Greek, Dutch, Czech, Hungarian, and all Nordic and Baltic pairs, with native voice talent based in-country. The most requested pairs for UK clients are English to Spanish, English to French, and English to Polish, followed by English to Ukrainian.
Which Asian and Middle Eastern languages do we cover?
Asian and Middle Eastern languages we cover include Mandarin, Cantonese, Korean, Japanese, Vietnamese, Thai, Hindi, Urdu, Bengali, Tamil, Arabic, Farsi, Hebrew, Turkish, and Pashto, with right-to-left subtitle rendering supported for Arabic, Farsi, Hebrew, and Urdu. Mandarin and Arabic carry the highest volume for corporate and eLearning content.
Which African and rare-pair languages do we cover?
African and rare-pair languages we cover include Swahili, Amharic, Tigrinya, Yoruba, Igbo, Hausa, Somali, Zulu, Sorani Kurdish, Kurmanji Kurdish, and Dari, sourced through our vetted network of native linguists in the diaspora and in-country. Rare-pair availability is the differentiator for asylum, NGO, and public-sector projects.
Pricing
How much do video translation services cost in the UK?
Video translation services in the UK cost from £30 per page for subtitle translation under 250 words, from £60 per hour for voice-over studio time, and milestone-priced for full dubbing projects above 10,000 words, with a 20% discount for new clients.
| Service | Starting price | Included |
|---|---|---|
| Subtitle translation | From £30 / page (up to 250 words) | Transcription, translation, time-coding, SRT/VTT, one revision |
| Voice-over translation | From £60 / hour studio time | Script adaptation, native talent, recording, WAV/MP3 delivery |
| Full dubbing | Milestone-priced (10,000+ words) | Casting, lip-sync recording, audio engineering, mixed master |
| Certified video translation | Fixed-fee per project | Signed statement of accuracy, court-ready PDF, burnt-in MP4 option |
| New-client discount | 20% off first project | Applies across all service lines |
What does subtitle translation pricing include?
Subtitle translation pricing includes source transcription, target-language translation, time-coding, SRT or VTT delivery, and one round of revisions, starting from £30 per page of up to 250 words. Burnt-in MP4 rendering and closed-caption versions with sound effects and speaker labels are quoted as add-ons.
What does voice-over and dubbing pricing include?
Voice-over and dubbing pricing includes script adaptation, native voice talent booking, studio recording, audio engineering, and synced delivery, charged from £60 per hour of studio time with talent fees quoted per project. Dubbing carries an additional lip-sync editing line because the target-language performance is timed to original mouth movements.
What factors change the final quote?
Four factors change the final quote, including total video runtime, target-language count, technical subject matter, and delivery deadline, with rush surcharges applied only when same-day turnaround is requested outside London business hours.
- Runtime — minute-count drives transcription and translation volume.
- Language count — each additional target multiplies linguist and QA effort.
- Subject matter — legal, medical, and technical content carries specialist rates.
- Deadline — same-day or out-of-hours delivery applies a defined surcharge.
How fast can a translated video be delivered?
We deliver translated videos same-day for orders placed before 11:00 GMT under 1,500 words, within 24 to 48 hours for standard subtitle and voice-over projects, and on agreed milestones for full dubbing projects above 10,000 words — all produced under ISO 17100 quality control with a two-linguist review at every stage. Same-day delivery is an operational commitment backed by our London-based project management team, not a premium surcharge. For multi-language commissions, subtitle sets covering up to five target languages are completed within three to five business days, because each language track is assigned its own qualified linguist rather than being handled sequentially by a single reviewer.
Turnaround time is determined by three variables: the total word count of the source script, the number of target languages requested, and the delivery format. Subtitle translation is the fastest track because it requires no studio booking; voice-over and dubbing projects include casting, recording, and audio mixing stages that extend the schedule. When a project combines subtitle translation with voice-over — as most eLearning and corporate training commissions do — we run both tracks in parallel wherever possible to avoid compounding lead times. For urgent legal evidence recordings destined for UK courts or the Home Office, we prioritise same-day certified delivery on request when the file is received before 11:00 GMT and falls within the word-count threshold.
| Project type | Turnaround SLA | Condition |
|---|---|---|
| Short subtitle translation | Same day | Order before 11:00 GMT, under 1,500 words |
| Standard subtitle or voice-over | 24–48 hours | Single target language, single linguist pool |
| Multi-language subtitle set | 3–5 business days | Up to 5 target languages |
| Full dubbing project | Milestone-based | 10,000+ words, casting and studio booking required |
Why us
Why Choose Our Video Translation Services?
What does ISO 17100 certification guarantee?
ISO 17100 certification guarantees that every translation passes through a qualified native translator and an independent second-linguist reviewer, with documented terminology management, project records, and corrective-action procedures audited annually. The standard makes the two-linguist model contractual rather than optional, which is why our certifications are accepted by UK courts, the Home Office, employment tribunals, and industry regulators. For video translation specifically, this means both the subtitle text and any voice-over script are reviewed by a second linguist before audio recording begins — preventing costly re-recording caused by errors caught late in production.
How is confidential video content protected?
We protect confidential video content through signed NDAs with every linguist, UK-hosted secure file transfer, GDPR-compliant data handling, and post-project file deletion on request, with named project managers as the single point of contact for each commission. Confidential projects — legal evidence recordings, pre-launch marketing videos, HR investigation footage — run on access-controlled folders limited to the assigned linguist pair and the project manager. Our ten-plus years of handling sensitive certified and sworn translations in the UK means these security protocols are mature and regularly tested, not improvised for individual requests.
Which industries does video translation serve?
We serve 6 industries with video translation, including legal and immigration, healthcare and life sciences, eLearning and corporate training, marketing and broadcast media, government and public sector, and technology and SaaS, each with named subject-matter linguists.
| Industry | Typical content | Preferred method |
|---|---|---|
| Legal and immigration | Evidence recordings, depositions | Certified transcript + burnt-in subtitles |
| Healthcare and life sciences | Patient education, clinical training | Voice-over + on-screen text |
| eLearning and corporate training | LMS modules, induction videos | Subtitles + SCORM-ready voice-over |
| Marketing and broadcast | Campaigns, TVCs, brand films | Full dubbing + localised graphics |
| Government and public sector | Public information, NGO field reports | Multilingual subtitle tracks |
| Technology and SaaS | Product demos, webinars | Subtitles + voice-over |
How are legal and evidence videos translated?
We translate legal and evidence videos with sworn linguists who produce certified transcripts and translations accepted by UK courts, the Home Office, and tribunals, with signed statements of accuracy attached to every delivery. Burnt-in subtitles are the default output because they cannot be detached from the evidentiary file.
How are eLearning and corporate training videos translated?
We translate eLearning and corporate training videos by combining subtitle translation with voice-over recording, LMS-ready file packaging in SCORM-compatible formats, and on-screen text re-rendering to match the original course design. Translation memory is applied across module sets so terminology stays identical from module 1 to module 30.
How are marketing and YouTube videos translated?
We translate marketing and YouTube videos by adapting taglines and humour culturally rather than literally, producing platform-ready subtitle files for YouTube, TikTok, Instagram, and LinkedIn, and supplying localised thumbnails on request. YouTube deliverables include multilingual subtitle tracks, localised titles, and translated descriptions ready for upload through YouTube Studio.
Which video file formats are accepted and delivered?
We accept video files in MP4, MOV, AVI, MKV, WMV, FLV, and broadcast ProRes, and we deliver subtitles as SRT, VTT, SSA, or burnt-in MP4, voice-overs as broadcast-quality WAV or MP3, and full localised videos in the production format requested by the client. Accepting a wide range of input formats is important because source material arrives from many different production pipelines — social media exports, broadcast edit suites, screen-capture eLearning tools, and legal recording systems all produce different containers, and clients should not need to transcode files before submitting them to us.
Subtitle output format determines platform compatibility: SRT is the most universally supported format across streaming platforms and social media; VTT is the standard for HTML5 web video; SSA supports advanced styling for broadcast and DVD; and burnt-in MP4 embeds the subtitles permanently into the video frame, which is required for evidentiary submissions to UK courts and the Home Office where the integrity of the combined video-and-caption record must be preserved. Closed captions — which include sound-effect descriptions and speaker labels for hearing-impaired viewers — are delivered as SRT or VTT alongside the translated subtitle track when accessibility compliance is required. Voice-over audio is delivered as WAV for broadcast insertion or MP3 for web and LMS platforms, and full dubbing projects are returned as a mixed master with the localised dialogue track replacing the original.
| Asset | Accepted input | Delivered output |
|---|---|---|
| Source video | MP4, MOV, AVI, MKV, WMV, FLV, ProRes | Mastered MP4 or ProRes |
| Subtitles | SRT, VTT, SSA, plain text scripts | SRT, VTT, SSA, burnt-in MP4 or MOV |
| Voice-over | Script document or transcript | WAV (broadcast) or MP3 |
| Dubbing | Source video with original audio stem | Mixed master with localised dialogue |
| Transcript | Source video | Time-coded DOCX or PDF |
How do you order a video translation from a London team?
You order a video translation from our London team in three steps: upload the source file through our secure UK-hosted portal, receive a fixed-fee quote within two hours during business days, and approve the brief to start production. For orders placed before 11:00 GMT involving scripts under 1,500 words, production starts and completes the same day. Every project — regardless of size — enters our ISO 17100 workflow from the moment the brief is approved, so the two-linguist review process begins at the translation stage rather than being added retrospectively before delivery.
- Upload — submit the source video and brief through our UK-hosted secure portal. We accept MP4, MOV, AVI, MKV, WMV, FLV, and broadcast ProRes, so no pre-conversion is needed.
- Quote — receive a fixed-fee quote within 2 hours during business days. Subtitle translation starts from £30 per page and voice-over studio time starts from £60 per hour; the quote confirms the exact cost before any work begins via Get a Free Translation Quote.
- Produce — approve the brief and deadline; your assigned linguist pair begins the same day for qualifying London orders. You receive progress updates from a named project manager who remains your single point of contact through delivery.
Our team covers more than 200 languages, so you request multiple target languages in a single order and receive a consolidated quote covering each language track. Certified video translations — those destined for UK courts, the Home Office, employment tribunals, or regulatory bodies — follow the same three-step process and are accompanied by our formal certification statement, confirming that the translation is accurate and complete to the best of the assigned linguist’s professional knowledge.
