Embed Desired subtitles(SRT/ASS/SSA) to MP4 movies easily and quickly

What is an MP4 File?

A file with the MP4 file extension is an abbreviation for an MPEG-4 Video file, which is a compressed file format that can contain not only video, but also audio and subtitles.

MP4 files are usually seen when you download a video from the internet or use a DVD ripping program to save a DVD to your computer.

Files like this that only have audio are sometimes saved with the .M4A extension.

How to Open an MP4 File?

The easiest way to play MP4 files is to double-click on the MP4 and let your computer decide which default application should open the it.

Since most people already have Windows Media Player or QuickTime installed, the MP4 should open automatically.

However, if no program opens the MP4 file then you probably don’t have a program installed that can view and/or edit MP4 files. I recommend installing one of the programs I just mentioned or the free VLC player, which is a fantastic MP4 file player that supports not only this video format, but many others, including audio files. MPlayer is another free MP4 player I like.
