There are a large variety of video conversion and encoding programs available online, and most can hardcode subtitles without too much difficulty. One of the most powerful and popular solutions is to use TEncoder, which is an open-source video encoder available for free download. Following are the detailed steps to insert subtitle to TEncoder.
Step 1: Place the MP4 video file and subtitle file in the same folder.
Make sure that the subtitle file has the exact same name as the video file. For example, if the video file is called “MyMovie.mp4”, the subtitle file should be called “MyMovie” plus the extension, which may be .srt, .ssa, or some other subtitle format. Both of these files should be in the same location on your computer.
Step 2: Open the video file in TEncoder.
Click the Add File button at the top of the TEncoder window to select the MP4 file that you want to add subtitles to.
Step 3：Select your video conversion options.
Below the file list, you will find several conversions options that need to be set before you can continue. Most of these options can be left to their default settings. You can change each of the options to suit the needs of your project, but to simply add subtitles to your video, nothing needs to be changed.
If you want to change the format of the converted file, choose a new format from the Video Codec list. If you want to keep it the same format, select Copy from them list.
If you want to lower the quality of the video to speed up the encoding process, choose a lower Video Bitrate. Setting this lower than the default can result in a noticeable reduction in quality.
Step 4: Enable the subtitles.
In the Other Options section, check the box labeled “Enabled subtitles”. Your subtitle file must be in the same folder as the video, and must have the same filename, otherwise the subtitles won’t load.
Step 5: Start encoding.
Once you have your options all configured, click the Encode button to start the process. This can take a significant amount of time if you have a slow computer, so start the encoding when you know you won’t need to use your computer for a few hours.
Longer videos and higher quality processing will take much longer than lower quality settings.
Tips: TEncoder may lacks the ability to handle certain MP4 file types such as H.265 MP4. If you even fail to load the MP4 video into the program, it would be much ideal for you to choose the first method.
