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.

Is there a way to change the font used for the subtitle? There\'s a button to do it, but it\'s grayed out for no apparent reason...

I think what you want to achieve is \'soft merging\' of subtitles - this you can achieve for example by \'Hand brake\'.

I\'m afraid not. The subtitle is chosen and \"write\" on top of the image. To play video with optional subtitle, VLC media player is recommended.

Is there a way to make the subtitles an option? Sometimes I want to use them and other times I do not.

I have a MKV file that is a foreign language movie with a subtitle english track embedded in it. It only gives me the option to \"load subtitle\" and then opens up a finder to select a file. I just want to enable the subtitle track on the MKV file. When I open it in VLC I can watch and see the subtitles. I just want to add the subtitle and make a MP4 file through video converter. Why does this seem so difficult.
