Which Subtitle Format to Use? (A Capital Captions Guide)

‘Which Subtitle Format to Use’ A Capital Captions Guide

For video makers both professional and amateur, when looking to distribute your videos either online or via broadcast, it’s important to consider adding subtitles. For broadcast programming and recently VoD services, closed captions are regulated and a legal requirement. Whilst transcribing text, timing it and adding it to video may seem straightforward, different broadcasters, channels and video platforms prefer different subtitling formats. In adding subtitles to your videos, it’s important to know which subtitle format to use and at Capital Captions, we’re here to help you get your captions right first time. In this blog ‘Which Subtitle Format to Use?’ A Capital Captions Guide we give you the breakdown of different formats for different vendors. 

Each table provides details on compatible formats, with the platform preferred format highlighted in bold text.

Professional Web Video Subtitling

When it comes to subtitling services, there is an enormous difference in terms of the price, complexity and standards expected when working with web vs broadcast video. For most web video, subtitles should be relatively simple (sometimes even automatic) in terms of transcription and timings.

If you are looking to add subtitles or closed captions to your web videos, below is a comprehensive list to some of the compatible subtitle formats:

Subtitle and Caption Burning Services

In addition to the many different options available in terms of closed captioning and subtitling formats and encoding, captions can also be burned onto video. When looking into which subtitle format to use, this is the option that stands apart from the rest. Subtitle burning is very much suited to bilingual videos and those which are aimed at the deaf and hard of hearing. Subtitle burning is also an option for sharing sites such as Twitter where there is no compatibility in terms of adding closed captions onto videos through the .srt format.

Subtitles can be burned in virtually any video format, including .MP4, .MOV, .WMV, .AVI, .MKV, .MPG, .TS, .TRP with encoding including MPEG-4, MPEG-2, .DIVX, ProRes, H.264 and more…
