Frequently Asked Questions
-
Can Geo Language Services provide multilingual subtitles?
Yes. We produce multilingual subtitles in any major language combination, in the file formats your platform or video editor needs (SRT, VTT, TTML, EBU-STL and others). Subtitles follow target-language reading-speed conventions, character-per-line and lines-per-screen limits, and on-screen timing rules. Each language version is reviewed by a second linguist before delivery.
-
Can Geo Language Services help with audiovisual content for safety briefings?
Yes. Safety briefing videos — site inductions, HSE training, emergency procedure videos, equipment safety — are a regular workload across our energy, life sciences and industrial practices. We handle transcription, translation, subtitling and voice-over with linguists who understand both the safety content and the target-audience language norms.
-
Are Geo Language Services' technical subtitling projects refined by an industry specialist?
Yes. Technical subtitling combines linguistic and subject expertise: the subtitler needs to understand what’s being explained on screen to subtitle it accurately within the timing and character constraints. We assign subtitlers with documented experience in your sector, and where the content is high-risk we add a technical specialist review on the timed subtitle file.
-
Which software does Geo Language Services use for technical subtitling?
We work with the major professional subtitling tools and deliver in any subtitle format your platform requires. Where you have a specific tool or platform preference (for example, in-platform subtitling on Vimeo, YouTube or a corporate LMS), we work in your environment.
-
Can Geo Language Services provide studio-quality voice-overs?
Yes. We work with experienced voice talent with access to professional studios to deliver broadcast-quality voice-overs in any major language. Voice samples are supplied so you can choose talent that matches the tone, age, accent and delivery style required, and recordings are produced under appropriate usage and broadcast rights agreements.
