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

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 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.

Differences in audio quality of mp4 and webm?

“WebM” and “MP4” are video formats (containers), so they are containers for video and audio.

There is another format (codec) for the audio inside, so I think the sound quality will change depending on the compression rate (performance) even at the same bit rate.

In other words, if the audio formats of the “WebM” and “MP4” files created by the caller use different audio formats, it is not possible to compare them simply by the size of the bitrate.

There is also a bitrate mode, like
“CBR (constant bit rate)”,
“VBR (variable bit rate)” and
“ABR (Average Bit Rate)”
.

Generally speaking, the amount of data is specified as
“CBR” = the same in any situation
“VBR” = changes depending on the situation
“ABR” = the average of the set is specified
.

Depending on the specifications of the video conversion software used, if you compare “WebM” and “MP4”, they probably both use advanced codecs with a high compression ratio and the quality and capacity of the audio data. There may not be a big difference, but there can be a considerable difference in capacity between “CBR” and “VBR”, so you may need to be careful about this.

It is safe to specify whether your video converter supports audio “dubbing”. Then there will be no deterioration.

And I think it is better to re-encode only the video with a lower bitrate.

In the “audio bitrate much higher for webm” situation, if both use advanced audio codecs, I think the webm file is likely to have higher sound quality. However, MP4 files may not degrade to a level that can be perceived by the human ear.

The video encoding is deep so if you are unsure you can either rip the audio or use the same bitrate and lower the video bitrate for encoding.

However, even if the audio is re-encoded at the same bit rate, it may not be recognized by the human ear unless it is in a lossless compression format (a format that can fully restore the original data), but it deteriorates a bit. .Keep in mind.

Everything you need to know about the WebM format

Everything you need to know about the WebM format

The WebM format was first introduced by Google in 2010. Since this video format is based on the Matroska container, it manages to maintain good video quality.

As far as audio streams are concerned, it supports Vorbis audio. The WebM format was originally designed for the web, as it supports HTML5. Video streams in this format are compressed using VP8 or VP9 video codecs. WebM is an open source alternative to other video formats (especially MP4) and is specifically designed for use on the web in conjunction with HTML5.

What is the WebM format?

WebM is a container format (with a * .webm file ending) for multimedia files, that is, for video and audio files. This container uses VP8 and VP9 video codecs and Vorbis and Opus audio codecs. First announced at Google I / O 2010, WebM was planned as an alternative to the existing MP4 format with its H.264 codec from the start. While the consumer can use the latter for free when watching videos, developers who want to work with the codec must pay license fees. WebM, on the other hand, is an open source project that everyone can use for free.

The WebP note is a format specifically designed for viewing image files on the Internet. WebM is designed to be used with HTML5. The VP8 and VP9 codecs were designed in such a way that there is a great compression ratio, but a bit of computer power is required to decompress the files. The purpose of this design is to allow streaming video online to virtually any device (such as a desktop, tablet, smartphone, or multimedia device, such as a smart TV).

So it is not surprising that YouTube, part 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 use WebM. While Google strives to promote its format, other major market players such as Apple or Microsoft continue to use formats such as MP4. The main reason for this is patent laws: both development companies are part of the MPEG-LA patent pool, as they hold patents for the codecs used and receive license fees for them. Google is trying to circumvent these patents with WebM.

In the past, this has led to various legal problems, for example in Germany. The problem was in the VP8 codec. Several companies have complained that the codec infringes on their patents. Subsequently, Google reached an agreement with MPEG LA. However, Nokia is not part of the patent group and it believes that its rights have been violated. The initial case, in which the company sued its V8-powered rival HTC, was dismissed by the Mannheim District Court in southern Germany. Fact A codec is a combination of the two terms “encode” and “decode”.

Two algorithms ensure that the video data is first encoded to keep the file size small and then decoded to restore the images and sound correctly. WebM files can be embedded into the user’s own website using an HTML5 video tag. one
WebM Support The WebM format is compatible with Mozilla Firefox, Google Chrome, Opera, Chrome, Chromium and Microsoft Internet Explorer browsers and requires no further installation to play files with this format. Microsoft Edge requires an additional plugin.

Apple Safari can also be upgraded to play WebM, at least for the desktop version. IPhone and iPad users have problems: they need to install additional software to play videos on their devices. Also, WebM video files can be uploaded to YouTube, which is one of the biggest problem for many users using YouTube channel. Also, popular instant messengers like Skype and ooVoo support this format.

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.
