Part 2: Other Video Subtitle Removing Tools (& Tutorial)

On top of WinX HD Video Converter Deluxe, there are other free video subtitle remover software available, including MP4Muxer, MP4Box, VirtualDub and FFMPEG. Since these 4 tools are similar in features, here we mainly focus on MP4Muxer for detailed introduction. As for another 3 tools, the conducting steps are much of a muchness.

MP4Muxer, as its name implies, is mainly designed for MP4 videos multiplexing and demultiplexing. Coming back to subtitles, it's able to demux all the tracks of MP4 video. That's to say, it can demux subtitles from MP4 as an independent file. When you play MP4 videos next time, the subtitles won't show up again. One thing to be noted is that it (including another 3 command line utilities) only extracts software subtitles from MP4, not hardcoded subtitles. Read the below guide if the subtitles in your MP4 file are soft ones.

Part 3: Extended Knowledge: Difference Between Hardcoded Subtitles and Soft Subtitles

Subtitle (captioning): Subtitles are derived from either a transcript or screenplay of the dialog or commentary in films, television programs, video games, and the like, usually displayed at the bottom of the screen, but can also be at the top of the screen if there is already text at the bottom of the screen... And subtitles are categorized into two kinds: Hardcoded subtitles and soft subtitles. Let's first figure out the difference between Hardcoded subtitles and soft subtitles.

Hardcoded subtitles: This kind of subtitles normally cannot be removed or turned off for the subtitles are irrevocably built in video, as a part of the video images. But there is a way to remove hardcoded subtitles from MP4 (MKV, AVI, etc.) movie video, discussed later in this tutorial.

Soft subtitles: This type of movie subtitles is not embedded in video images. It is an independent stream and can be easily turned off/on. Viewers can also freely select subtitles based on their needs if there are multiple language subtitles tracks in the (MP4) movie video. Soft subtitles are mainly used on DVD/Blu-ray.

Difference Between Internal and External Subtitles

Besides, movie subtitles can be classified into internal and external subtitles. Internal subtitles are embedded in a file container along with video and audio streams, while external subtitles are separate files that are easier to edit and change. This post will also discuss how to add external subtitles to MP4 (MKV/AVI) video.
