Some movies and video clips are with built-in subtitles, in whatever subtitle formats. Despite the convenience and advantages in many aspects of subtitles, it makes me feel bored when I have the needs of secondary video clipping or video splitting and video editing just for my personal collection. Normal subtitles, shown in MKV, MP4, AVI and other video file formats, actually exist in different types, thus different methods should be used for removing them.
There are two kinds of subtitles currently, one is soft subtitlewhich is also called external subtitles; and the other is hard subtitleembedded in the video as a part of video images. Of course, we can download some video processing software which looks professional but complicated to operate, as it requires more time and energy to learn. And some people among us have ever tried to put mosaics into the video where subtitles are shown, which will definitely influence the picture effects and sometimes affect our understanding of the movie at last.
So we can see that the above ways are not so good. There is the step-by-step guide on how to use the all-powerful subtitle remover to remove soft or hard subtitles. You can directly Free Download the software here.Hard-subbing without vlc player (ffmpeg)
We can see the multiple subtitle options are listed in the drop-down window, then the subtitle of this video is soft subtitle type. Import videos by pressing "Add Files" or drag the video into software, and then you can see the video in task list.
You can also load more videos at one time. At the task list, you can see a button as "T". The whole process is as easy as winking. You will get a movie without quality loss and totally subtitle-free in a couple of minutes.
Just try it by yourself and from now on, enjoy a subtitle-free movie anytime anywhere! Open the output format drop-down list on the right of UI to select an output video file format.

How to Remove Subtitles from MKV, MP4, AVI and So On
It's a very capable Matroska manipulator and should be able to remove any kind of stream from an MKV without recoding all the other streams. Sign up to join this community.

The SRT format is by far my favourite subtitle format. Its spec has its oddities not least that there is no widely accepted formal specbut in general if you stick to the accepted commonalities of the format between media players, you'll find it's not only simple, but easy to modify and script around. If you have another format, like SSAfor example, you'll probably find that ffmpeg does a pretty good job converting it with ffmpeg -i foo.
I won't go into too much detail on this, since you probably will have good enough luck Googling "[movie] [language] subtitle", but here are some recommendations:. You may find that your subtitles are not encoded as UTF-8 and require conversion. Let's take Chinese subtitles as an example, as they often use country-preferred encoding schemes. Chinese subtitles usually come encoded as Big5 or GB I personally find that enca is pretty good at detecting the encoding and converting it appropriately.
I'll assume you're using a Matroska file, since they're so popular nowadays, but much of this will also apply elsewhere. Inside an MKV file are multiple streams.
They contain things like the video data, the audio data, and subtitles. You can list them with ffprobe :. Say you want to extract the Spanish subtitle to an SRT file. When converting, ffmpeg will pick the first suitable stream that it finds — by default, then, you will get the English subtitle. To avoid this, you can use -map to select the Spanish subtitle for output. These are not part of the SRT spec, they remain to be interpreted by the media player.
Since not all media players support this sometimes they are just shown raw, which looks quite bad. The srt project contains a tool to deal with this called processwhich can perform arbitrary operations on files:.

It only takes a minute to sign up. I'm trying to re-encode video streams from a Matroska file to save space, while keeping all the subtitles as-is, using ffmpeg. I want to write a generic command that works without me having to specify exact stream numbers.
Now I can't figure out how to let ffmpeg pick its default video stream and default audio stream and then all subtitles. The current input file I'm working with has these streams, but other files will have different streams.
As far as I can tell from the manual, -c:s copy is supposed to copy all the streams, not just the default one, but it won't. Perhaps it's a bug? To clarify, what I'm after is the result: one v ideo, one a udio and all s ubtitles. The stream selection default behavior only selects one stream per type of streamso inputs with multiple audio streams will create an output with one audio stream.
To disable this behavior and manually choose desired streams use the -map option. These examples use -c copy to stream copy re-mux from the input to to the output. No re-encoding occurs. Sign up to join this community.

However, ffmpeg complains about the subtitles format - it cannot decode the stream. Since I don't need this subtitles stream, I'd like to know how can I disable subtitles stream decoding during conversion?
There is such option as -sn which disables subtitles decoding from input stream. Also there are analogous options for audio and video decoding: -an and -vn respectively.
It also turned out that there is another way to achieve this. One may use the -map option to select which streams are to be decoded. So omitting the subtitles stream among the -map options does the job. The former command line deselects the subtitles stream probably all of them, if there are several while the latter one selects only the necessary streams to decode.

Note that a subtitle stream need not be present for the entirety of the video and may first appear only when the first subtitled dialogue occurs. Thus, the subtitle stream may not be detected and listed by:.
Note that both of these options must appear on the command line before the specification of the input via -i. For example:. Subtitles may be included in an encoded video file as a parallel streamor may be rendered permanently aka "burned" into the video itself.
Set subtitle language using the ISO language code 3 letters. S tream : S ubtitle : Number of stream, starting with 0. Subtitles may be rendered permanently into the video stream by specifying a complex filter on the command line:. This can be interpreted as "take all video streams from the first listed input, then all subtitle streams from the first listed input, and overlay the latter on the former to produce a single video stream that replaces all consumed streams".
The new stream will be mapped by the encoder as any video input stream normally would. IFO file on the DVD, but this is not available to ffmpeg and thus the colors of subtitles will be largely arbitrary unless the palette is specified on the command line with:.
Unfortunately, the palette entries used to render the subtitles vary from one video to the next, so some experimentation is required. Typically one entry will determine the font color and another entry will determine the outline color, though some videos have subtitles that use multiple outlines, each with its own palette entry. The full command line to search relatively deeply for a subtitle stream and then render it in green on black into an h output video might look as follows:.

I have a mkv video I want to convert to mp4, but every which way I try and convert it Handbrake, WinFF, ffmpeg, mencoder, I lose the video's subtitles. How can I convert the video,keeping the subtitles, or add a subtitles. MP4 supports streaming text format subtitles, but playback support for this among players and devices is not universal.
Basic example using default stream selection behavior while stream copying the audio:. Example to stream copy all of the video and audio streams, convert the all text based subtitle input streams SRT, ASS, VTT, etc to the streaming text format, and set the language for the first two subtitle streams. Same as above but re-encode the video and audio to formats compatible with the MP4 container H. Same as above but use the -map option to choose the first video stream, second audio stream, and third subtitle stream:.
Note that this requires re-encoding, so it will by much slower than using softsubs. Use the overlay filter. This example will overlay the fourth subtitle stream over the second video stream, and stream copy the seventh audio stream:.
If it is not possible with the format, ffmpeg should then error out. Normally -map is used to define stream mapping - i. If you just want to do a simple conversion to mp4 you can use VLC. VLC will accept a subtitles file and render it onto the output. Well I found a way to make it work, not ideal, but it works.
I can add a srt to a video with mkvmerge. Only downfall is it makes the video mkv, not mp4. Ubuntu Community Ask! Sign up to join this community. The best answers are voted up and rise to the top.
