You want to subtitle your video and don’t know in which format to transcribe it?
There are many subtitle files out there. Other than well-known SRT and VTT formats, there are less popular files that are yet in demand by some software. You may also seek a format with more flexible customization. Not easy to find your way around !
So how do you make the right choice? We give you our list to guide you through all these possibilities.
Why is the choice of subtitle format important?
The choice of the subtitle format you use is not trivial. For your transcript file to work, it needs to comply to a specific structure. For example, if you have created a TXT file of your video’s dialogue, it won’t work for most video players. So you need to arrange it according to a fairly precise coding.
Fortunately, most video players and software support more universal formats like SRT and VTT. But some video editors may request a rarer format (like ASS or TTML).
In any case, choosing the format that best suits your needs will help you to :
- Save time in your subtitling work, by using a format accepted by all your platforms
- Optimize the appearance of your subtitles, by selecting a format that gives you more freedom to customize
- Avoid technical problems with display and compatibility with your tools

It’s even more advanced version ASS (Advanced SubStation Alpha) has even more precise graphic and textual features. Furthermore, it allows you to make animated subtitles and lyrics for karaoke videos.
