The problem

Viewers don’t give a video a second chance

They click away the moment a video feels foreign, rushed, or hard to follow. These are the problems we prevent.

  1. Subtitles nobody can finish reading Three crowded lines that vanish before viewers reach the end. Timed to natural reading speed, two lines at most.
  2. Text and voice out of step A half-second lag makes viewers lose the thread and lose trust. Spotted to the audio and to shot changes.
  3. A voice that doesn’t fit A flat or mismatched voice undercuts the message and the brand. Native talent you hear and approve first.
  4. English left on screen Titles, lower thirds, and slides stay in English after the audio changes. On-screen text localized to match.
  5. Viewers who can’t follow at all Without captions or SDH, deaf and hard-of-hearing viewers are left out. Captions and SDH that support ADA and Section 508 obligations.
  6. Unreleased video in the wrong hands A campaign or training video leaks before launch. Handled under ISO/IEC 27001 controls.

Your options

Subtitles, voiceover, or dubbing: choose how they’ll hear you

Each format gives viewers a different experience at a different cost. Many projects combine them, such as voiceover for training and subtitles for social clips.

Our process

From source video to every language, frame by frame

Every project runs through the same six stages, whether it is one training module or a full video library.

  1. Transcribe and adapt the scriptWe transcribe the source, then translate and adapt it for reading speed, or for spoken timing and lip movement.
  2. Spot and timeSubtitles are timed to the audio and to shot changes so text never lags or flashes.
  3. Cast the voicesYou hear auditions from native voice talent and choose the voices before anything is recorded.
  4. Record and directA director guides each session for pronunciation, emotion, and timing against the picture.
  5. Mix and checkAudio is mixed to your delivery specification, and a second linguist reviews every line in context.
  6. Deliver to your platformYou receive files in the formats your player, LMS, broadcaster, or social channel requires.

Voice casting

Voices your audience trusts, chosen by you

The right voice sounds like it belongs to your brand and your viewers. You set the brief, hear the auditions, and approve every voice before we record.

  • Native speakers of the right varietySpanish for U.S. audiences is not Spanish for Spain. We cast for the market you are reaching.
  • Directed sessionsA language director coaches pronunciation of names, terms, and acronyms during recording.
  • Consistent voices across seriesThe same narrator for every module, so your training sounds like one program.

What is the difference between subtitles, closed captions, and SDH?

Subtitles translate the dialogue for viewers who can hear the audio but don’t speak the language. Closed captions are for deaf and hard-of-hearing viewers: they include dialogue plus speaker identification and important sounds such as music or a door slamming. SDH, subtitles for the deaf and hard of hearing, carry the same information as captions in a subtitle format, which is common on streaming platforms. We produce all three, and many organizations need more than one.

What is the difference between dubbing and voiceover?

In voiceover, a new voice in the viewer’s language is recorded over the original, which is lowered but still faintly audible, or the video is narrated entirely in the new language. It is ideal for training, e-learning, and corporate video. In lip-sync dubbing, the original dialogue is fully replaced and the translated lines are adapted to match the speakers’ lip movements, so the video feels as if it were made in the viewer’s language. Dubbing takes more script adaptation and studio time, so it costs more.

Should we choose subtitles, voiceover, or dubbing?

Choose subtitles when you need many languages quickly and cost-effectively, when viewers often watch without sound, or when accessibility is the main goal. Choose voiceover when viewers need to focus on the screen, such as in software training or safety instruction. Choose lip-sync dubbing for brand films and on-camera content where the experience must feel native. Many projects combine formats, and we recommend one after reviewing your videos and audience.

How much do subtitling, voiceover, and dubbing cost?

Subtitling is usually priced per minute of video. Voiceover and dubbing depend on the script length, the number of voices, studio time, and how the recordings will be used. Other factors include the number of languages, whether a transcript or script already exists, on-screen text, and your delivery specifications. Send us the videos or a sample, and we will give you a firm quote before work begins.

How long does it take to subtitle or dub a video?

Timing depends on runtime, the number of languages, whether a script exists, the number of speakers, and how many rounds of voice approval you need. Subtitling is the fastest format; dubbing takes the longest because of casting, recording, and mixing. We confirm a delivery schedule in your quote and can stagger languages or deliver in batches for large libraries.

Which subtitle file format do we need?

It depends on where the video will play. SRT works on most players and social platforms, WebVTT is standard for web and HTML5 players, SCC is common for U.S. broadcast captions, and TTML or DFXP is used by many streaming platforms. Subtitles can also be burned into the picture when a platform cannot display caption files. Tell us your platforms and we will deliver the right files.

Can we approve the voice talent before recording?

Yes. We share auditions from native voice talent who match your brief for language variety, gender, age, and tone, and you approve the voices before recording begins. For series and training programs, we keep the same voices across every module so your content sounds consistent.

Do you offer AI dubbing or synthetic voices?

For high-volume internal content such as training updates, AI-assisted voice can reduce cost and turnaround. Our linguists review every line for accuracy, pronunciation, and tone, and we use only voices licensed for the purpose. For customer-facing, emotional, or brand-critical video, we recommend human voice talent. We will tell you which approach fits each piece of content.

Do captions make our videos ADA and Section 508 compliant?

Accurate, synchronized captions are a core requirement for accessible video under WCAG, which Section 508 and the ADA rules for public entities reference. Accessibility also depends on how the video is published, such as whether the player displays captions, and some content also needs audio description for blind and low-vision viewers. We produce captions and SDH to support your obligations; confirm your specific requirements with your accessibility or legal team.

How do you protect unreleased or confidential video?

Video is handled under our ISO/IEC 27001 certified information security management system. Files move through secure transfer, access is limited to the linguists, voice talent, and engineers assigned to your project, and everyone involved works under confidentiality agreements. We retain or delete files according to your instructions.
