As you might know, adding subtitles to your video is one of the best way to improve the viewing experience. Subtitles increase the accessibility of your videos for healing-impaired audiences and provide them with a readable visual support. With translation, they also help you share your content around the world, regardless of nationality and language.

But not just any type of captions can do the trick. Doing subtitles is actually a hard and demanding job, that needs to comply to specific rules and format. For example, the media and broadcasting industry in the United States strict regulations (Twenty-First Century Communications and Video Accessibility Act of 2010). They follow also precise guidelines like the ones of BBC or Channel 4. That includes :

- Transcribing the speech of your video accurately and withing a proper format. 
- Making subtitles in a readable and accessible style
- Translating properly the semantic and cultural differences of each language
- Having a work-flow productive repeatable and scalable.

Depending on the subtitle company or agency, there are different types of services you can get : 

Freelance and self-employed

This is the cheapest option on the market. By hiring a freelancer, you get quality subtitles for your video for a reasonable price and delivery delay. However, it all depends on which independent subtitlers you are relying on. They don’t have the same skills and experience, and they don’t handle all languages. 

Translation and subtitling agencies 

There are the oldest and most experienced providers on the market. They provide the skills of professional teams of translators and subtitlers to take care of your big video workload. They often have diverse area of expertise in terms of media type, software, and languages. But they are slow in adopting new technologies to speed up their workflow. So they are not the most effective service providers on the market.

Platforms for subtitle service providers

Subtitle platforms connect you directly with subtitling and translation professionals (agencies and freelancers). They will take charge of your project according to the deadlines and conditions you choose. The benefits are that you get attractive prices and the expertise of actors who have already proven their skills. The drawback is that you don’t have always full visibility and control on your projects.

Professional and automatic subtitle applications

This is the latest innovation in the subtitle marketing. Applications like Checksub combine human expertise and automatic technologies. They process your video with speech-to-text based transcription processing and hire subtitle experts that will optimize your result. They also take care of professional video translation project by using both translation API and human translator expertise. With this choice, you make sure you get the best and fastest result on the market for your video strategy and company needs.
