How to Add Subtitles to MP4 Videos
Wanna add a subtitle to your own recordings to create your own movie? Or add a subtitle to a foreign movie for understanding the movie better? It’s quite easy to do the subtitle task with iSkysoft Video Converter for Mac.
At the very beginning of the task, something you need to know: not all videos can have subtitle, i.e, if you have some FLV videos, you are unable to attach external subtitles to the video. Those proper video formats for subtitle attachment are MP4, AVI, MKV etc. But with iSkysoft Video Converter for Mac, the format limitation is nothing. Taking adding subtitles to MP4 for example, you can download the Mac app and:
Import the source MP4 files to the Mac Video Converter
To add the source videos, you can drag & drop your files directly to the Mac app, or head to File menu and choose Load Media File. Batch conversions are supported.
Note: If you have some videos in FLV, 3GP, AVCHD or other formats which don’t support subtitle attaching, you can also use the Mac Video Converter to add subtitles to the video.
Add subtitle to MP4 video
There is a subtitle box next to the thumbnail of the video on the video info bar, you can click it to open a dropdown menu and choose Load subtitle. You can add subtitles in srt, ass and ssa to the videos.

You can keep MP4 as your output format or choose other formats. The default output format set by the Mac app is iPhone MP4, if you wanna a change, open the format list by clicking the format icon on the video info bar and customize the output format.
