[0:00] Welcome to full course online.
[0:02] In this tutorial, you will learn how to
[0:04] add subtitles to a video using FFmpeg.
[0:08] Before we begin, if you want to know how
[0:11] to configure and install FFmpeg, watch
[0:14] another video in this playlist.
[0:16] That video will guide you step by step
[0:19] through the installation.
[0:21] Now, let's continue.
[0:26] You need three things before adding
[0:28] subtitles.
[0:30] ffmpeg installed on your computer. Open
[0:34] command prompt and type ffmpeg.
[0:40] If you see output like this, then ffmpeg
[0:43] is configured on your PC. If not, then
[0:46] watch this video. Second thing you need
[0:49] is a video file. For example, my
[0:51] video.mpp4.
[0:54] In our case, the file is stored in D
[0:56] drive. Let me play the video.
[1:00] >> Hello everyone. Welcome to full course
[1:02] on
[1:03] >> As you can hear the voice of a female.
[1:06] Let me check the subtitle. And as you
[1:08] can see, there is no subtitle available.
[1:12] The third thing you need is a subtitle
[1:14] file in SRT format. For example, my
[1:17] video. SRT.
[1:19] If you don't already have a subtitle
[1:21] file, you can create one with a text
[1:24] editor. Here is a simple example.
[1:28] Line one starts with a number. Then
[1:31] comes the timing.
[1:33] For example, 0 hours, 0 minutes,
[1:38] 1 second
[1:40] to 0 hours,
[1:44] 0 minutes for seconds.
[1:47] Then write the subtitle text.
[1:51] Save the file as my video. SRT.
[1:58] There are also many transcribe tools
[2:00] available which can convert audio file
[2:03] to SRT.
[2:08] Now let's add subtitles in a soft
[2:11] format.
[2:12] This means the subtitles are inside the
[2:14] video but can be turned on or off. The
[2:18] command is given on the screen. Here's
[2:21] how this command works.
[2:23] The first dash I gives the input video
[2:26] file which is my video.mpp4
[2:28] located in the D drive. The second dash
[2:32] I gives the subtitle file which is my
[2:34] video. SRT located in the SRT folder
[2:38] inside the D drive.
[2:40] - Copy means copy the video and audio
[2:43] streams without re-encoding. So there is
[2:45] no loss in quality. - C col sRT tells
[2:50] FFmpeg to take the subtitle file and
[2:53] save it as an SRT track inside the
[2:55] output container.
[2:57] Finally, we name the output file as
[3:00] output MKV.
[3:02] Mention correct path of both video file
[3:04] and SRT file. The output file name is
[3:08] output and will be stored on D drive.
[3:11] This keeps the video quality the same
[3:13] and only adds the subtitle track.
[3:21] Let us test it. Open the output file in
[3:24] VC media player.
[3:26] >> Hello everyone. Welcome to full course
[3:28] online.
[3:29] >> As you can see now we can turn on
[3:31] subtitles
[3:34] >> in the search box. A list of websites l
[3:38] >> you can see the subtitles on the screen.
[3:40] Now,
[3:44] if you prefer MKV format, the command is
[3:47] slightly different. The command can be
[3:50] seen on the screen. Here's how this
[3:53] command works. The first dash I tells
[3:56] ffmpeg the input video file. In this
[4:00] case, it is my video.mpp4 stored in the
[4:03] D drive. The second dash I tells FFmpeg
[4:07] the input subtitle file. Here we are
[4:10] using my video. SRT stored inside the
[4:13] SRT folder on the D drive. - Copy means
[4:18] copy the video and audio streams exactly
[4:20] as they are without re-encoding.
[4:24] This makes the process fast and keeps
[4:26] the original quality.
[4:28] - CSRT
[4:30] tells FFmpeg to copy the subtitle file
[4:33] and embed it as an SRT track in the new
[4:36] container.
[4:37] And finally we give the output file name
[4:40] as output.m MKV which will be saved in
[4:43] the D drive. This way the MKV file
[4:46] includes the subtitles as a separate
[4:49] track.
[4:59] That's it. Now you know how to add
[5:01] subtitles to any video using FFmpeg.
