MP4 Video

Mp4 or MPEG-4 is a digital multimedia container format most commonly used to store video and audio, but can also be used to store other data such as subtitles. Many movies you download now are in MP4 format.

Subtitles

SRT (.srt) short for (SubRip Text) is a basic subtitle format that contains formatted lines of plain text in groups separated by a blank line. Most subs you download now are in .srt subtitle format.

Why Merging SRT Subtitles with MP4 Movies?

There are devices like Playstation 3 (PS3), Xbox 360, some TVs and DVD-players that don't support the .srt subtitle format. When you add subs to your movies, they don't show up while playing the movies on these devices. The only way to fix this, is to merge subtitles with movies (also called hardcoding). When you hardcode subs, the subs will permanently be burned into the video file. The two files will become one file.

Here are two good websites for downloading subtitles:

How to Merge SRT Subtitles with MP4 using WinX HD Video Converter Deluxe

This method isn't free, because you need the reliable and fast WinX HD Video Converter and this will cost you a few dollars.

But:

It will save you a lot of time, effort and headaches.

Now:

You're probably thinking "So I need to convert all of my movies? That's not what I was looking for. I only need a simple and fast way for merging subtitles with my movies".

Wait! Don't leave this page yet. Give me a moment to explain.

Look:

I've searched a long time on the internet for finding a solution to easily and quickly merge srt subtitles with Mp4 movies and many of these solutions took a very long time to execute, reduced the quality of the movies, or the subs were not synced with the movie.

As owner of this website, I often get the chance to try out software for free, but I only make reviews and how-to tutorials about programs that are good and reliable.

I tried WinX HD Video Converter and found out that it's a good and user friendly video converter that can easily convert your videos to all kinds of video formats and devices.

WinX HD Video Converter isn't free, but offers great value for your money – especially if you are going to merge srt subtitles with mp4 movies more often.

And:

With this Video Converter it only took me about 20 minutes to merge srt or sub and idx subtitles with full movies in Mp4 format. That's fast! With free video converters it will take you much longer, and it will often reduce the quality of your movies, and many times the subs are not synced with the movie (showing the wrong sentence at the wrong moment / time).

If you are planning to merge a lot of movies with subs, then 49 dollars (maybe cheaper) are well spent on software that can save you a lot of time, effort and headaches.
