Differences and similarities between 264 and H.264 formats

The.264 format is the raw elementary streams of H.264-ES video files (also referred to as MPEG-4 temporary video file). In turn, H.264-ES is part of the H.264 format specification. Older DVRs record video in.64 format. Such video files cannot be used for direct viewing by ordinary players and require processing by special programs.

H.264 format allows you to reduce video recording to a minimum size. After the videos are fully compressed, the video and audio quality is still high. CCTV cameras and video recorders of a new type work with this format. H.264 files are also referred to as MPEG-4 Part 10 AVC / H.264. Despite the long and scary name, it is very easy to find an H.264 file player on the net.

To open such files, you must use one of the following methods:

  • use special programs and utilities;
  • convert video files.

What is h264 and h265?

H264 is a hardware codec that allows you to record video from a camera, capture it from a computer, and receive it in many other ways. H264 and H265 are widely popular in recording devices due to support for hardware encoding method (which is much faster than software) and the ability to save the final video in almost any modern format.

  • Supports hardware video encoding method, so you can achieve better recording quality and frame rate even on very mediocre hardware.
  • The ability to save videos in almost any popular format.
  • H264 is supported by almost all modern hardware and software.
  • In the absence of hardware encoding on the hardware, h264 can work in software mode, although it will be much slower and worse.

H265 is a more modern codec designed to replace the outdated h264 over time. This codec is distinguished by increased speed and quality of images, but video recording in h265 is supported by a rather small amount of equipment. Only the most expensive cameras and DVRs support shooting using this codec.

Using media codecs

Not all users will want to change the player to play the maximum number of video formats. In this case, you can install any of the modern codec packages into the built-in Media Player. There are not too many high-quality codec packages on computers:

  • K-Lite Codec Pack is one of the most common and old codec packs. It is distributed in several editors, it is recommended to use the Full or Mega edition to play video from cameras, other versions may lack the necessary components. This package also allows you to install Media Player Classic on your computer.
  • ADVANCED Codecs is a younger, but no less advanced codec package. In addition to the standard features, it allows you to programmatically improve the quality of the video being played, although it does this very mediocre.
  • The Media Player Codec Pack is a media codec pack designed to be embedded exclusively into the standard Windows Media Player. When installing it, the user will not be prompted to install an alternative player, otherwise it is practically no different from analogues.
  • XviD Codec is a codec package designed primarily for converting video rather than playing it. It is perfect when you need to convert a picture from a camera into a format understandable for most devices. For normal playback, the previous codecs are enough.

How to open h264 from CCTV camera?

Video surveillance systems are an integral part of equipment in offices, businesses and even in some homes. But the recordings from the cameras will be completely useless if the user cannot open them. It is not always possible to open the content from cameras with a player built into the operating system, since a codec that is not installed on a personal computer can be used during recording.

How to open processed h264 and h265 (avi, mp4 and similar formats)

In the overwhelming majority of cases, the user does not even have to install anything, modern operating systems (both stationary and mobile), with all the updates already available “out of the box”, can open processed videos from cameras.

If the videos downloaded from the recorder or filmed with a separate camera do not open on a computer or mobile phone, then additional software will need to be installed. As such software, you can install another player, with which all videos will be opened, or use a codec pack that adds support for new formats to the built-in Media Player.

Most popular players for Windows PC:

  • VLC Media Player is an advanced video and audio player based exclusively on free software. The player is characterized by low resource consumption and high operating speed;
  • KMPlayer is one of the most popular players supporting a huge number of video formats, adding third-party effects during playback, and many other features. KMPlayer has one drawback. huge requirements for computer resources, which makes it work poorly on weak PCs;
  • ALLPlayer is a relatively young player, a distinctive feature of which is playing archived files without the need to unpack them first.

There are many other players for the computer, the final choice depends solely on the user’s preferences.

What to do with RAW video?

Some DVRs and IP cameras take pictures exclusively in raw format, using the h264 or h265 codec. As a result, videos do not open on other devices without first converting to more common and understandable formats. Basically, owners of professional cameras face this problem, but it also rarely occurs in video surveillance systems.

  • Sony Vegas Pro is an excellent video editor from Sony that allows you not only to convert videos from one format to another, but also to perform many other actions. Basically, this application is used to work with Sony cameras, but other cameras / DVRs are quite supported.
  • Adobe Premiere is a video editor from Adobe. This application will appeal to users of other products from the company, for example Photoshop, since all programs from Adobe are synchronized with each other.

Not everyone has the opportunity to purchase a paid video editor or install a hacked version, so there are also free analogs:

  • OpenShot is a free video editor based exclusively on free software. A distinctive feature of the program is the most simple and intuitive interface.
  • ShortCut is another free video editor that differs from the previous one mainly in interfaces.
