The .SUB file extension stands for a text-based subtitle file typically used in DVD movies and tracks created with software like SubRip. It is the most popular subtitle file format and is widely supported by various media players, so it can be used on almost any device and platform. SUB file is plain text containing the words spoken in the movie in sync with the played video. The supported audio languages are shown as extra parameters within the file.
File Structure
A SUB file typically contains two lines of text per dialogue, where the first line is the timecode representing when the dialogue starts, followed by a second line representing the subtitle. The typical timecode structure is "HH:MM:SS.MMM" where HH stands for hour, MM stands for minutes, SS stands for seconds and MMM stands for milliseconds.
Similar File Formats
Some similar subtitle file extensions are .SSA, .ASS, .SRT, .SMI and .PKS. Usually, they are stored in subfolders with the same names or simply inside the video folder as a part of its metadata.
Converting SUB files to Other Formats
Depending on its compatibility with particular playback devices or platforms, users may need to convert between subtitle formats for usability purposes. Users can leverage their favorite tool to quickly convert from one type of file to another. For instance, online tools like Cloudconvert allow users to quickly (convert.SUB to.SRT) and is completely free of charge.
Supported Software
Below are some software tools that support this particular format:
Programs for WINDOWS system
Programs for MAC system
Programs for LINUX system
After installing the required software, the operating system will usually automatically associate an unknown file type (in this case .SUB) with the new application. If this does not happen, we can help the system a bit by selecting the software for it, which it should always use to open files with the .SUB extension.
When choosing the software we can select the system to use this software every time.
Remember!
Using it for the first time it is good to check whether the .SUB file opened in the application can be read by us and opens in a way that allows us to use it. If everything is in order, select this option the next time you open a file with the .SUB extension. However, if the file has not opened correctly, we have to look for a different software, with which we can open files with the .SUB extension. Select a different software from our list and install it on your computer. After the software is installed, repeat inspection openings of a .SUB file. Sometimes you have to repeat the operation several times.
Other instructions
If none of the programs listed by us to work with the .SUB file has not meet your expectations, you can try searching other websites. But remember to avoid downloading programs "that can open any file". These applications not only have very limited functionality, but may also expose you to expense tens of dollars when purchasing a license.
In the vast majority of cases you will find the program dedicated to support the .SUB file, or any other file format. In addition, there is a chance that it will be a free program, and its functionality (concerning the .SUB file) will be extended to the maximum.
It is also good to check
- if the .SUB file has no errors
- or if it has been copied (or downloaded by the browser) thoroughly
