Differences between WebM and MP4 – Compare in terms of image quality, file size, compatibility, etc.

WebM vs MP4

A common question is which is better, WebM or MP4. For example, for “mp4” and “webm”, which one has better image quality, which one consumes more space under the same conditions, and which one should be selected to convert or download the video for storage? There are several things.

What is WebM: An open video file format developed and published by Google. A subset of the VP8 format for video compression, the Vorbis format for audio compression, and the Matroska format (MKV / MKA) for the file format (container format).

MP4: One of the file formats for storing video data compressed in MPEG-4 format. MP4 is a format derived from ISO / IEC 14496 Part 12 developed based on the Apple QuickTime media technology file format, and has a structure that follows many of the conventional QuickTime formats.

Let’s take a look at the commonalities and differences of WebM MP4
WebM and MP4: image quality
This is an important point when selecting the video format to see if the video is displayed in high quality. Which is better than WebM MP4 in terms of image quality? In fact, the image quality of WebM and MP4 is closely related to the codec. In short, the MP4 format provides ultra-high definition picture quality that is in no way inferior to DVD playback screens.

On the other hand, WebM also provides high image quality, but compared to MP4, WebM seems inferior in image quality. Here, the difference between WebM VP8 video codec and MP4 h.264 video codec will be described as an example. VP8 and H.264 achieve approximately the same image quality at the same bit rate. But now H264 is a little better?

WebM and MP4: size
When importing videos to your iPhone iPad Xperia Andorid portable device or posting them to an online video sharing site, the file size is important. Both WebM and MP4 have excellent compression performance and can save videos in a small size. And the videos in MP4 format can be easily downloaded from the website in no time using a high-speed broadband connection. However, the size of the MP4 file can naturally increase because our goal is to achieve a high image quality similar to that of a DVD.

WebM, which is often used for streaming over the Internet, is popular on Google sites. For videos viewed in a browser, the WebM format is recommended because it has a smaller file size and better image quality than MP4.

WebM and MP4: compatibility and versatility
If you want to play videos on your smartphone or tablet, please choose MP4 format. It is no exaggeration to say that MP4 is the most supported video format right now. Not only is it compatible with Apple products and services, it can also be used on Android devices. So that you can comfortably enjoy MP4 videos using iPhone, iPad, Android, Chrome browser, Safari, IE 10 (using Flash and HTML5) and other players.

From the above WebM MP4 comparison, WebM is exposed to a more serious situation. However, both Microsoft and Apple have announced that they will support WebM on their smartphones and operating systems. And Windows and Mac OS computers can rely on Flash for WebM compatibility. As a video format developed for the Web, WebM shows overwhelming performance.

WebM: What you need to know about the WebM format

With the support of Google, a new multimedia file format appeared on the Internet in 2010. WebM is an open source alternative to other video formats (especially MP4) and is primarily designed for use on the Internet in combination with HTML5. But what can this WebM format do that other video formats cannot?

WebM is a container format (with the file extension * .webm) for multimedia files, that is, videos and audio files. The VP8 and VP9 video codecs, as well as the Vorbis and Opus audio codecs, are used in the container itself. First announced at the Google I / 0 2010 conference, WebM was planned from the outset as an alternative to the existing MP4 format with its H.264 codec. The latter can be used at no cost to consumers when viewing a video, but developers who want to work with the codec must pay license fees. WebM, on the other hand, is an open source project that anyone can work on without paying any fees.

WebM is designed to be used with HTML5. The VP8 and VP9 codecs are designed in such a way that although a lot of compression occurs, little computing power is required to unpack. The purpose of this concept is to enable streaming videos on the internet on almost all devices (be it desktop computers, tablets, smartphones, or multimedia devices like smart TVs). Therefore, it is not surprising that YouTube, as a subsidiary of Google, converts all videos to the WebM format, regardless of the original file format. However, YouTube continues to support H.264 for those who cannot play WebM.

WebM has now become a political issue in the Internet community. While Google is trying with all its might to establish the audio and video format, other big players in the market like Apple or Microsoft are sticking to formats like MP4. The reason for this is mainly the patent system: the two software companies are in the patent pool.

WebM Player: How to use WebM?

WebM is compatible with some of the main web browsers out of the box: Chrome, Chromium, Firefox and Opera do not require any additional installation to reproduce the format. Microsoft Edge requires an additional plugin. Apple’s Safari can also be upgraded to play the WebM format, at least on the desktop version. It becomes troublesome for iPhone and iPad users – they have to install additional software to be able to play the video format on their devices.

WebM vs. MP4 – pros and cons

While WebM is still relatively young, MP4 (MPEG-4 Part 14) and H.264 have been used for many years. Since then, that has made the older format and codec a standard – you will find few use cases where MP4 is not supported. In addition to Internet services and PC / Mac software, many devices (eg video cameras) can also handle MP4. The high level of acceptance makes the format interesting for both manufacturers and users.

But Google scores with the open source nature of WebM: using the format does not incur any cost to manufacturers, developers or end users. Furthermore, the software is distributed under the open BSD license.

The licensing network behind MP4 and H.264 is opaque – most users, even those who create professional videos, don’t even know if they can already have a valid license by purchasing hardware or software or if they have a valid license for each video. the license rights violated. With WebM, this mess is eliminated. However, as early as 2010, MPEG LA announced that the use of the H.264 codec will remain free in the future as long as the created videos are available to users for free.
