How to Add Subtitles to an MP4 File

Edited by Pat Bitton

March 19, 2020

Many film 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 a disc already have hardcoded translations.

Why add subtitles to your video? Here are some situations in which they may become handy.

Learning or practicing a foreign language

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

Watching an undubbed foreign film

Dubbing films takes a lot of time, and some of them may not get an English dub at all. Use subtitles to understand what’s happening.

Listening to the original audio of a movie

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

How to Add Subtitles to MP4 Videos in Movavi Video Converter

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 films 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., AVI, VOB, FLV, and M4V), joins separate videos, compresses media, even changes the resolution of any video.

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.

Add Your MP4 Files

Click Add Media, then choose the Add Video option. Select the videos you want to attach subtitles to. The files will be added to the program.

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.

Choose the Preset for Conversion

Open the Video tab and select the MP4 format. If you are satisfied with the resolution of your video, choose the MP4 H.264 - Original Size option. If not, you can choose any other resolution from the list that you feel would work better.

Add SRT to the MP4 Video

Select the target folder for your videos by clicking the Save to button at the bottom of the program window. By default, the subtitled videos will be saved in the Movavi Library folder. Hit Convert to add SRT to the MP4 files. The folder with the output files will open as soon as the processing is done. Now you can put the hard-subbed video on a DVD or transfer it to any device.

Now you know how to add subtitles to MP4. You can follow the same simple steps to embed subtitles into videos in any other format (including AVI, MOV, WMV, or MPEG).
