H.265 has several advantages over its predecessor, H.264. The most significant ones are:

Better Compression

H.265 uses more advanced compression techniques, which enable it to achieve better compression rates than H.264. This means that H.265 can deliver the same video quality as H.264 with less data. This is particularly important for video streaming, where bandwidth is often limited.

Support for Higher Resolutions

H.265 supports resolutions up to 8K, while H.264 only supports resolutions up to 4K. This makes H.265 more future-proof and suitable for applications that require high-resolution video, such as virtual reality or surveillance.

Improved Parallel Processing

H.265 is designed to take advantage of multi-core CPUs and GPUs, which makes it faster and more efficient than H.264. This is particularly important for real-time applications, such as video conferencing or live streaming.

H.264 vs. H.265: Which One is Better?

So, which one is better? The answer is not straightforward, as it depends on the specific use case.

H.264 is Still Widely Used

H.264 is still the most widely used video codec, as it is supported by almost all devices and software. This means that if you want your videos to be compatible with as many devices as possible, H.264 is still a safe choice.

H.265 is More Efficient

However, if you are looking for better compression and support for higher resolutions, H.265 is the better choice. It is also more efficient in terms of processing power, which can be a significant advantage in certain applications.

The Future of Video Codec

In any case, it is clear that H.265 is the future of video codec. As more and more devices support it, and more content is encoded in H.265, it will become the new standard for video compression.

Conclusion

In conclusion, both H.264 and H.265 have their advantages and disadvantages. H.264 is still the most widely used video codec and is compatible with almost all devices and software. On the other hand, H.265 offers better compression, support for higher resolutions, and improved processing efficiency. As technology advances and more devices support H.265, it will become the new standard for video compression.

What is a video codec?

video codec

A codec is a program or device that encodes and decodes video. This means that it takes a video and compresses it into a smaller format so it can be streamed or stored more efficiently. Then, when you want to watch the video, the codec decodes it and plays it in its original format.

Why is a video codec important?

Video codecs are important because they make videos more accessible and easier to use. Without a codec, the videos would be too large to stream or store, which would mean that we would have to wait a long time to watch them or have a very large storage space to save them.

In addition, the codecs also make the videos look better. Some codecs use advanced techniques to compress the video without affecting its quality. This means that we can see sharp and clear videos, even when they are compressed to a smaller size.

Codecs are also important because they allow videos to be compatible with different devices and platforms. For example, if a video is encoded with a specific codec, it can be viewed on a computer, smartphone, smart TV, or game console without any problem.

What types of video codecs are there?

There are many different types of video codecs, but some of the most common are H.264, H.265, VP9, and AV1. Each codec has its own advantages and disadvantages, and some are better for certain uses than others.

For example, H.264 is a very popular codec used to compress high-definition video. It is a good option for most users as it is compatible with most devices and platforms. However, H.265 is a newer codec that is more efficient in terms of bandwidth and can offer improved video quality.

VP9 is an open source codec developed by Google that is used on some devices and platforms. AV1 is an open source codec developed by a coalition of technology companies and is a promising option for the future, offering more efficient compression and improved video quality.

It is important to note that not all codecs are created equal and some may require more processing power or bandwidth to function properly. Therefore, it is important to choose the correct codec for each situation.

Conclusion

In conclusion, a video codec is an essential program or device that allows you to compress and decode videos to make them more accessible and compatible. There are many different types of video codecs available, and it’s important to choose the one that’s best for each situation. Mp4Gain is an excellent solution for those looking to optimize and enhance their video experience.

H.264 video codec

This codec was developed by the ITU (International Telecommunications Union) with the sober name h.26L. In 2001 several consortia and companies joined forces and continued development jointly. Microsoft also participated in the development of H.264.

H.264 CODEC

This video codec is now compatible with numerous companies and end devices, including Adobe and Apple. The H.264 codec is one of the video codecs that has also made the leap to the codecs compatible with Blu Ray and HD-DVD. Well, the quality of this video codec is amazing, but it comes at a price. Very few video bloggers and small businesses will invest in the staggering licensing costs.

H.264 levels and profiles

In 2003, the first versions of the H.264 video codec were released with the ITU-T H.264 standard. In this standard, the first 3 profiles were defined for H.264, the baseline, the main and the high profile. Over time, the High 10, High 4: 2: 2 and High 4: 4: 4 profiles were added. These profiles define the encoding parameters to be used, as according to the standard not all features can be used arbitrarily .

Various H.264 levels have also been defined in the ITU-T H.264 standard, which define the maximum video sizes, bit rates, and other parameters such as the number of macroblocks allowed in the H.264 video codec. To create true standards-compliant H.264 videos, visit Wikipedia’s H.264 level overview and adjust its parameters according to your desired level / profile.

x264 is the most widespread derivative of the H.264 codec under the GPL and at the same time command line encoder for the H.264 MPEG-4-AVC video format. It is an open source solution that is available for all platforms such as Windows, Linux, and Unix.

This encoder was developed as part of the VideoLAN project and can be downloaded for free from the project pages at http://www.videolan.org/developers/x264.html.

Video Formats: Everything You Should Know

There is currently a wide variety of video formats available to store multimedia content in a file and play it on our devices. Depending on this format (and other multiple factors) the video will basically have a different video quality and a smaller or smaller file size.

However, if you are not up to date on these issues, you may get lost since we enter concepts such as formats, codecs, containers or related terminology such as AVI, MP3, MP4, DIVX, XVID, OGG, MKV, OGG , FLV, MPG, VP9, HEVC, AAC, H.264, AVC and much more.

Guide to convert video formats

In this brief but detailed guide, our objective will be to explain the difference between all these concepts, often confusing, clearly separating terms such as “container video format” and “video codec”, in addition to learning along the way a simple and practical way of Convert videos to different formats.

Outline of a container format

To begin, we must be clear about the difference between these two concepts that are often confused very often: the container format and the video codec. The first one is really the format of the file, the one that surrounds everything (audio, video, etc …), while the second is the format directly related to the video part:

Container format

But let’s see a description of each concept to make it even clearer:

Container format: A video file usually has a specific container format, such as AVI, MP4 or MKV, for example. As the name implies, a file with this format contains several elements (usually and at least, video and audio). However, it is possible that it only includes one of them, or for example multiple audio channels (to have several languages of the same file). Some container formats also allow you to include other elements such as images or integrated subtitles, without the need for external files.

Video codec: It is often confused with the video format, but it really is not the same, since it is related to the video content and not to the container format. It is not a mandatory element, since if a codec is not specified, the video is contained in RAW (uncompressed), taking up a lot of space (for example, 200MB about 10sec). For that reason, a codec is usually chosen to compress the video. Depending on the codec’s choice, better or worse quality will be achieved, and in turn, larger or smaller.

Video specification: Each video codec is usually based on a specific video specification (H.262, H.263, H.264 …), which is nothing more than a set of rules that define how it should behave. This can guide us to know if one codec is more or less recent than another.

Audio codec: In the same way as with the video, we have possible audio channels included in the file. They are also usually compressed with a certain codec to save space: MP3, OGG Vorbis, WMA …

Once this is clear, we will review the most popular container formats and the video codecs that they usually use (this does not imply that they cannot also be used in other container formats):

AVI format (Microsoft, 1992)

Perhaps, in all likelihood, one of the best known container formats is the AVI (Audio video interleave). It was developed by Microsoft in 1992 and is one of the most popular formats, perhaps because of its wide use on Windows platforms. Being one of the first container formats it is the most basic and only allows audio and video channels (although multiple of them can be included, if desired).

If we focus on video codecs, the AVI format accepts almost any VFW-compatible codec, but the most commonly used are the well-known DivX or XviD (which is a bifronte of the previous one).

DivX codec

DivX became popular in version 3.11 and was nothing more than a modified version of a Microsoft codec. Subsequently, and due to its success, they rewrote the code so as not to violate Microsoft patents. However, the DivX project became proprietary, generating a tremendous difference of ideas and causing the birth of a free brother codec: XviD.

Related to DivX was the Stage6 platform which was a kind of YouTube that allowed uploading high quality videos for the time. However, it did not have the necessary financing and failed economically.

XviD codec

XviD became popular as a result of the detriment DivX experienced, surpassing it due to its good quality, efficiency and its open source character. In addition, it also began to be supported on a large number of homemade DVD players, where perhaps, one of the first that stood out was the KISS DP-450.

Although there are currently technically better codecs, XviD is still updated and is still used due to its popularity, compression speed and good performance.

MKV format (Matroska, 2002)

MKV format (Matroska)
MKV format (Matroska)
Matroska, better known by MKV, the extension used in its archives, is an open-source container format that bases its name on the classic Russian Matrioskas dolls that fit inside each other. In addition to the MKV extension (used for video, audio and possible subtitles), there are other extensions used such as MKA (audio only), MKS (subtitles only) or MK3D (3-dimensional video).

Codec x264

This format usually uses some H.264 implementation (codec specification) as a video codec, such as x264. On the other hand, for the audio section you usually use the Vorbis audio codec.

WebM format (Google, 2010)

One of the most recent container formats is WebM (WebMovie), a project slightly based on Matroska. Initially it was developed by the company On2 Technologies, but in 2010 it was purchased by Google, which released the project as a source code, orienting it to the objective of using it with HTML5 as a free standard.

The format has excellent performance and, together with the VP9 codec, make it a very interesting option that seems to have a lot of future.

VP9 codec

The video codec used by WebM is known by VP8, developed by the company On2 Technologies (after a long evolution from TrueMotion S, used in games like Final Fantasy VII). Originally, WebM used VP8 video codec alongside Vorbis audio codec, however, it currently uses VP9 video codec alongside Opus audio codec.

MPG format (ISO, 1993/1995)

Probably, MPEG-1 and MPEG-2 are one of the most complex concepts to understand. First of all, it must be made clear that these are specifications, and not a format in itself, so each specification is made up of several different concepts:

MPEG-1 / MPEG-2 specification
MPEG-1 / MPEG-2 specification
MPEG-1 Specification (ISO, 1993)

The first one, MPEG-1, is the one used to define the first container format (MPEG-PS) and the VCD storage format (VideoCD, based on H.261). Subsequently, some modifications compatible with VCD that used MPEG-2, such as SVCD (SuperVCD) or KVCD, would also appear.

As a curiosity, mention that contrary to what many people believe, the famous MP3 audio files are not MPEG-3, but MPEG-1 and are defined in the third part of the specification.

MPEG-2 Specification (ISO, 1996)

The second specification, MPEG-2, is the one used to define the container formats (MPEG-PS / MPEG-TS) and the new DVD storage format (H.262). Some MP3 features were also improved and AAC (Advanced Audio Coding), an advanced audio format with numerous improvements over MP3, was introduced.
