Video on Demand Closed Captioning Services
Since February 2017, the Subtitle It! campaign run by Action on Hearing Loss achieved success and the government voted in favour of a new bill to be passed. This will require that VoD broadcasters include closed captions or subtitles with their content. Ofcom is now in a consultation period during which they will develop their code of practice further, in order to set out just how much video content will require subtitling. Following on from the news, the subtitling and closed captioning industry has seen a significant rise in demand for Video on Demand closed captioning services.
At Capital Captions, we provide professional, reliable and cost effective services to write, time and encode our clients VoD captions. Here’s more information about both our closed caption services and the VoD subtitling industry in general.
Video on Demand Closed Caption Formats
Closed Captions (known in the US as subtitles for the deaf and hard of hearing or SDH) can be created and displayed in a range of different formats.
Most online video content which is closed captioned today uses the .SRT subtitles format. The .SRT format is basic, flexible and also highly compatible with a vast range of software. It is frequently used on social media sites as well as video sharing platforms such as YouTube, Vimeo and Facebook.
Subsequent to the growing popularity of the .SRT subtitle format, we have seen the rise of .VTT (also known as WebVTT) subtitle files growing in popularity online. The concept of WebVTT captions is to provide easy to manage and edit subtitle format’s which is almost identical to .SRT format’s but includes styling and formatting options which .SRTs do not.
Different Video on Demand service providers use different formats but probably the most widely used is the DFXP format; (also known as TTML, timed text mark-up language, XML or EBU-TT).
Below are some brief summaries of closed caption formats accepted by some of the major Video on Demand service providers:
- Amazon Prime include captions that are in SMTPE-TT, EBU-STL, EBU-TT, DFXP, TTML, iTT, SCC or SRT subtitle formats.
- Netflix subtitles for the deaf and hard of hearing SDH) are in subtitle formats including DFXP, TTML or XML subtitle format.
- BBC iPlayer subtitles and closed captions are accepted as EBU-STL subtitles or TTML (also known as W3C, XML or DFXP).

Converting Television Broadcast Subtitles for Video on Demand Services
It’s not surprising that broadcast closed captions and VoD closed captions differ in formatting. Broadcast subtitles are traditionally encoded into Line-21 of a television signal but online video content is displayed in a much more simple way; effectively as an extra subtitle file that is accessible alongside the video. Formatting and conversion issues in video on demand services lie not in the difference between broadcast and online content but rather in the different devices and platforms which display the captions.
Take BBC iPlayer as an example. Viewers can access the iPlayer via TalkTalk, Virgin Media, Wii, PS4, Amazon, Blackberry, Apple and more… In turn, these platforms can be accessed across a range of devices including PCs, Macs, laptops, tablets and smartphones. As different platforms accept different subtitle formats, there is an enormous need for subtitle conversion when looking to closed caption large amount of video.
VoD Subtitle Conversion Services
At Capital Captions, we provide cost effective, reliable and high quality conversions of broadcast and television subtitles and closed captions into formats required for Video on Demand services.
Our subtitlers work tirelessly in not only quickly re-purposing clients’ subtitles but in proofreading and quality checking the display of closed captions and subtitles following the completion of the subtitle conversion process. This can be incredibly important when you consider that subtitles contain not only differences in format and style, but also in the coding in which they are written, such as UTF-8. If the format is changed but not the encoding, foreign characters may display inaccurately and consequently, sections of your completed closed captions may become almost unreadable.
