Figuring out the most suitable format for your videos is a serious matter. Choosing an incompatible one may lead to irreversible damage and you may even have trouble accessing your videos. You also have to pick a format that is supported by most media players.

With these conditions, the best format you’ll come up with is MPG and MP4. While these two formats have their similarities, there are also differences that set each other apart. And that’s what we’re going to talk about in this article.

Today, you’ll find out in this MPG vs MP4 comparison which is the better format and how you can switch between these two. Let’s start with a detailed comparison.

Part 1. MPG vs MP4: Detailed Comparison

In this detailed MPG vs MP4 comparison, we’ll be looking at different aspects of these two formats and we will decide on which is the better format according to how well they do on each of these factors. Let’s start with an introduction to both formats.

Introduction to MPG and MP4

MPG is short for MPEG. It’s the original format that uses the MPEG codec, particularly MPEG-1 and MPEG-2, while MP4 stands for MPEG-4. In other words, MP4 is a later version of MPG, but that doesn’t always mean that the newer version is better. This also means that they are both from the same company, which is the Moving Picture Experts Group. These two formats are often used for videos that are distributed on the internet.

That’s pretty much for the introductions, now we head to another section of this comparison.

Supported Video Codecs

Since they are both made by the same organization, you’d expect that they support the same video codecs. Actually, MP4 wins by a mile in this aspect.

While MPG only supports the MPEG-1 and MPEG-2 video and audio codecs, MP4 supports numerous other codecs such as H.264/AVC and H.265/HEVC. It also supports unfamiliar codecs including Cinepak, Dirac, MVC, and more. In other words, you’ll find a lot more files that are compatible with MP4 than with MPG. Considering how codecs decide how well the videos are presented, this is a big hit to MPG.

Video Quality

When it comes to video quality, there’s not much difference between the two. As previously said, the codec is one of the deciding factors of how well the video will look. But since they both support MPEG-1 and MPEG-2, you can expect that they’ll look similar. However, one thing to keep in mind is that MP4 uses more modern video compression. And because of its access to more advanced technology, MP4 wins on this aspect as well. So right from the get-go, we can tell that being more advanced, MP4 has an edge over MPG.

File Size

Video quality and file size are, in most cases, proportionate to each other. If the file size is lower, then the video quality is also lower. This is general knowledge for those who work with videos. However, that’s not always the case. For example, even though H.265 and H.264 codecs are known for their relatively small size since files in the old days were quite small, MPG videos have a very small file size. In this aspect, it’s a draw since both formats have their own advantages on being smaller in file size.

Compatibility

When we talk about compatibility, we’re referring to whether the format is compatible with media players or not. This time, MPG wins against MP4.

Since MP4 is mostly used for videos on the internet, some media players don’t take into consideration the MP4 format. As such, you’ll find a couple of players that can’t play MP4 files. On the other hand, as the pioneer of the MPEG codec, the majority of media players support MPG. However, that does not mean that all players support these formats.

Since weighing the pros and cons is crucial for most comparisons, we’re going to do just that with the next section.

MPG vs MP4

Pros and Cons of MPG

Now we head to yet another important aspect of the MPG vs MP4 comparison. And yes, we’re going to start with MPG. Let’s start with the pros:

  • Most commonly-used format on media players
  • Best for recording videos
  • Has a smaller file size

Another advantage of MPG is that it’s easier to convert into other formats, especially since it’s a basic file format. This time, let’s talk about its cons or disadvantages:

  • Has lower video quality due to smaller size
  • Only supports a limited number of codecs

Although it’s not a good match for MP4 which is a relatively advanced format, MPG still does pretty well compared to other newer formats.

Pros and Cons of MP4

This time, we’re going to discuss the pros and cons of MP4. I’ll begin with the pros or advantages of MP4 over MPG:

  • Best for internet videos
  • Has a higher vide quality
  • Supports a lot of codecs from old ones to advanced codecs

On the other hand, the cons of MP4 include:

  • Has a bigger file size
  • Some media players do not support the format

After reading this detailed MPG vs MP4 comparison, you must have already come up with a decision on which format you’re going to use. Regardless of your decision, you will need a converter capable of convert MPG to MP4 and vice versa without quality loss. And that’s what the next section will be all about.
