Video Translation:
Reaching Global Audiences


Subtitles – adding simultaneous translated text to video content – are a key feature in increasing the audience of any production.

Whether it’s a film, website, video game or webinar, adding subtitles will allow a greater share of the viewing public to enjoy and engage with it. That’s why subtitles are so important: they affect the very perception of what’s being presented.

A big proportion of all online traffic already belongs to video content, and this is only expected to increase in the future. The result? Subtitling services are likely to become even more important.

The subtitling process in detail


Subtitling is very complex and involves many steps: translation of the actual content, rearranging the text into segments, organizing each unit to be displayed on the screen, and adding a time code to each one. Last but not least, there’s the rather technical process of adding the subtitles to the video itself.

In addition to all that, there are a few other things to consider: the native and target languages, the length of each video, the amount of content that needs subtitling, the style, and, of course, the deadline of each project. And, just like any content translation, subtitling requires a lot of context. Simple word-by-word translation won’t do. It’s crucial to localize the content for the target viewers.

Automatic or human subtitling?


The ideal is to use every resource that can save time and cut costs. Efficient subtitle-generating programs are available, and they can be used together with transcription and voice recognition applications.

But even when using the latest programs to maximize efficiency, it’s always a good idea to retain the human element. Especially considering challenges like local expressions, jargon, or complicated words that might not be captured by a machine.

For this reason, it’s always better to have native-speaking professionals involved in the subtitling process – at least as part of the review and editing stage. I really need subtitling?

When we think of subtitles, the first thing that comes to mind is probably the film industry. But in reality, subtitling can be useful for virtually any industry or organization that aims to expand its users.

Think of marketing and advertising content, public announcement videos, educational content from platforms with international viewers – the possibilities go on and on.

Also, every social media platform has a strong video presence today. Considering the popularity of these websites – and of other video platforms – the impact generated by video subtitling might be even more important than translated text content.
