What are Soft Subtitles?

Soft subtitles, a.k.a. softsubs or closed subtitles, are like closed captions that can be turned on and off during the video playback. They exist as additional files added to the video container (MKV, MP4, and MOV), making it very different from hard subtitles whose subtitle text is irreversibly burned in the video frames. Softsubs are commonly used for fansubs. To display or close softsubs when playing a video requires a player with subtitle support. Such players include VLC, Windows Media Player, MX Player, and KMPlayer.

Soft subtitles can be very helpful when it comes to watching foreign movies or learning a foreign language. But sometimes, it could be a distraction, too. If you think there’s a need to add subtitles to MP4/MKV/MOV or remove soft subtitles from videos, read the following two parts that show you exactly the way to do it without re-encoding. Hope you’ll find it helpful.

Step 1. Import Source File

Launch HD Video Converter Factory Pro and open the Converter. In the next window, click + Add Files to load the needed video into the program. Or you can directly drag and drop the file into the converter.

Tips: If you have multiple videos that you want to add subtitles to, you can add all these files into the converter for later batch processing at once.

Step 2. Choose Output Format

Click the right-side format image to open the output format library. Go to the Video tab and select one of the three formats, MP4, MKV, or MOV (these are the only formats that support soft subtitles) as the output format.

Step 3. Add Soft Subtitles

In the main workspace, click the "+" button next to the "T" option to add your needed subtitles. You can add more than one subtitle file to create multiple subtitle tracks. Next, go to the H option and switch the subtitle type to CC (Here you can get more detailed information about each subtitle type and its supported format). Repeat this whole step to your every video if you have imported more than one video.

Note: If you have added multiple subtitles, remember to tick off all the subtitles you want in the "T" option after you’ve switched to CC subtitle type.

Step 4. Start Processing

Click the bottom triangle button to specify an output path or leave it as default. Finally, hit Run to start the process. It should be done in an instant.
