1. SubRipper (.SRT)

It is the most used subtitle file format, especially for YouTube and Facebook videos. In this file format, the data is saved as SubRip file format with the extension of .SRT. The main reason for its excessive use is its understandable and compact manner.


In this subtitle file format, you can easily see numeric sequences to show the pattern of the lines of text in your video. So, it will be easy for the subtitle converter to edit srt file of subtitles and add it properly to the video.

2. WebVTT (.VTT)

Undoubtedly, it is easy to add subtitles in different formats like srt in video content. But it may be hard to add subtitles in the live streaming videos. Based on the srt file format, the WebVTT format is designed to overcome such issues.


This file format is mainly used in live-streaming videos because of its responsive features. You can change the color, position, font style, and size in this format. That's why famous streamers use this subtitle file over text files to give viewers a clear preview.

3. Sonic Scenarist Closed Caption (.SCC)

This format is normally considered a standard subtitle format, particularly in multiple streaming platforms. It is a closed-caption format that organizations and companies of large scale widely use to deliver their subtitle data.

Reading and editing .SCC file isn’t an easy task, especially for beginners. The reason is when you open this file in Notepad or in another program, it seems to be complicated to read it. That's why beginners normally use a video subtitle generator to get this file and deliver it to the customer.

4. MicroDVD (.sub)

Another subtitle file format used in media players, especially, is MicroDVD. This file will have an extension of .sub in the file property that you can check easily. Undoubtedly, it is used widely in videos written on DVDs or films.


But it is hard to use this file format because of frame rate dependency. Unlike the SRT file format, it is based on frame rate instead of numbers. So, it will be a challenging task to adjust the frame rate with the text file.

You will see merged subtitles or a blank line while previewing the video if you cannot match them. So, it is much more complicated to add this subtitle file to your video as compared to other formats.

5. Distribution Format Exchange Profile (.dfxp)

If you are working as a video editor or subtitle editor, you must know about the DFXP file format. This file format is widely supported in tools used by professionals, including Adobe Flash.
