Video files are a fundamental part of modern digital communication, entertainment, and professional workflows. From streaming movies and online tutorials to surveillance footage and smartphone recordings, video files allow moving images and sound to be stored, shared, and played back across a wide range of devices. At their core, video files are containers or streams of visual data that rely on specific encoding standards, also known as codecs, to compress raw video into manageable file sizes while maintaining acceptable quality. Understanding how video files work, and how different formats relate to one another, helps explain why some files open easily while others require specialized software.
One of the most influential and widely used categories of video files is based on the H.264 standard, often informally referred to as “264.” H.264 is not a file extension in itself but a video compression format developed by the ITU-T and ISO/IEC. It is officially known as Advanced Video Coding (AVC). The reason H.264 became so dominant is its ability to deliver high-quality video at relatively low bitrates compared to older standards. This efficiency made it ideal for online streaming, Blu-ray discs, video conferencing, and mobile devices, all of which need to balance quality with bandwidth and storage limitations.
When people encounter “264” in practice, it is often as part of a raw video stream or embedded within a container file. For example, many MP4 files use H.264 as their video codec, even though the file extension is .mp4. In some cases, especially with security cameras, DVR systems, or professional video capture hardware, the video may be saved as a .264 file. These files typically contain raw H.264-encoded video without the additional metadata and structure found in common containers like MP4 or MKV. As a result, .264 files can be difficult to open with standard media players, even though the underlying video data is widely supported.
The popularity of H.264 can be seen across many everyday applications. Streaming platforms commonly use H.264 to ensure smooth playback across different devices and internet speeds. Smartphones record videos using H.264 because it produces smaller files that are easier to store and share. Video conferencing tools rely on it for real-time compression and decompression, allowing clear video calls even on modest connections. This widespread adoption means that H.264 has become something of a universal language for video, even if users are not always aware of it.
In contrast to H.264-based video, there are many other categories and formats of video files, each with its own purpose and history. One well-known example is MPEG-2, which was widely used for DVDs and early digital television broadcasts.

MPEG-2 files tend to be much larger than H.264 files at similar quality levels, which is why they have largely been replaced for online and mobile use. Another example is H.265, also known as HEVC (High Efficiency Video Coding). H.265 is the successor to H.264 and offers even better compression efficiency, but it requires more processing power and is subject to more complex licensing, which has slowed universal adoption.
AVI files are another familiar type of video file, especially on Windows systems. AVI is a container format developed by Microsoft and can hold video encoded with many different codecs, including older ones like DivX or Xvid. While AVI files were once very popular, they are less efficient than modern containers and often result in larger file sizes. MKV, or Matroska Video, is a more flexible container that can hold multiple video, audio, and subtitle tracks in a single file. MKV files frequently contain H.264 or H.265 video streams, making them common for high-quality video distribution.
MOV files, associated with Apple’s QuickTime framework, are another important example. Like MP4, MOV files are container formats that can include H.264 video. They are widely used in video editing and production environments, particularly on macOS. FLV files, which were once common for online video playback through Adobe Flash, also often used H.264 video streams, although the container itself has largely fallen out of use.
What all these examples illustrate is that video files are not defined solely by their extensions. A file’s ability to open and play correctly depends on both the container format and the codec used to encode the video data inside. This is why a .264 file, despite using a well-known and widely supported codec, may not open in a default media player. The player may expect a container structure, timestamps, or indexing information that raw H.264 streams do not include.
This complexity can be confusing for users who simply want to view a video file they have received or recovered from a device. Surveillance systems, dash cams, and industrial equipment often output video in specialized formats like .264, assuming that proprietary software will be used for playback. When that software is unavailable, outdated, or incompatible with the user’s system, the video can appear inaccessible even though the data itself is intact.
FileViewPro is designed to solve exactly this kind of problem. Instead of requiring users to identify the correct codec, container, or proprietary player, FileViewPro provides a single, easy-to-use application that can open and view hundreds of file types, including video files based on H.264. When dealing with a 264 file, FileViewPro can recognize the underlying video data and present it in a playable format, eliminating the need for specialized surveillance software or complex conversions. This makes it especially useful for users who need quick access to video files from cameras, DVRs, or unfamiliar sources, allowing them to view their content without technical barriers or guesswork.
