How to Add Subtitles to MP4 Videos

Edited by Pat Bitton

Many movie fans are familiar with the SRT format. These small files contain subtitles for your favorite ongoing anime or a Korean drama. Unfortunately, not every player can read external subtitles. It’s also much more enjoyable to watch a mix of Oscar nominees on your DVD player if the files you want to burn to disc already have hardcoded translations.

SRT (short for SubRip) is the subtitles format widely used to add a translation or additional information to movies. SRT files can contain only text data, without video or audio. However, you can format the subtitles text to change the style. Each phrase in the SRT file has its own timecode for when to appear and disappear.

Why add subtitles to your video? Here are some issues you might encounter.

Learning or practicing a language

Watching movies or series with subtitles helps you to learn new words and phrases faster. You can also see how names are spelled and improve your writing and reading skills.

Watching a movie that has not been translated

Translating the voiceover for a whole movie takes a lot of time, and you may not want to wait. Moreover, some movies are not going to be translated. In these cases, you can use subtitles to understand what’s happening.

Wanting to listen to the original soundtrack

A soundtrack is an important part of every movie, so it may be useful for you to listen to the original. Subtitles will help you to follow the storyline.

If you want to combine a video with SRT subtitles, Movavi Video Converter is the tool you need! You can encode the translation permanently with it, so you can watch your favorite movies and series on any device.

However, the program does not just hardcode subtitles, it can do a lot more! Movavi Video Converter also converts files into different formats (e. g. MKV, AVI, VOB, FLV, and M4V), joins separate videos, compresses media, even changes the resolution of any movie.

Here is a step-by-step guide for how to integrate external subtitles into a video.

Install the Subtitle Adder

Download the installation file for Mac or Windows, open it and follow the instructions to install the software.

Select the Subtitles

Click No subtitles in the output information section. In the pop-up window, click the Add button and select the subtitles you want to insert into your video. If the SRT file has the same name as the video and is located in the same folder, the program will suggest the subtitle track automatically, and it will appear in the list of subtitles. You can also choose the Apply to all files option to merge the subtitles into all the chosen videos.

If you want to find subtitles online, after clicking Add, choose Search online. In a new dialog box, just click Search. You will get a list of subtitles that match the metadata of your file. Select the subtitles that suit you best.
