Without subtitles, it’s hard to know what’s native speaker saying when watching some foreign movies in a .mp4 format. Do you want to attach your preferred subtitles to the MP4 videos, so that you can play and watch them easily? This article is going to offer two possible solutions to adding subtitles to MP4 videos that you've downloaded or got from other sources.

Step 2. Attaching Subtitles to Movie by Handbrake

Using a common media player like Quicktime or VLC to play the movie, you can also display subtitles simply by putting the subtitle file in the same folder. The only requirement is that both the movie and the subtitle files should go under the same name but with different extensions. Something like "title.mp4" and "title.srt".

Important Note: In our tests on inserting subtitles to some downloaded movies using Handbrake on Mac, but not having much success. When tired to add an .srt subtitles to an .mp4 file that we have already converted in Handbrake, Handbrake immediately thinks it has already converted the movie and hence does not add subtitles.
