Guide to Know What is H263

Have you ever encountered the term H263 while dealing with videos? If you're unsure what it means, you're not alone. H263 is a video compression standard, but it might not be as widely known as some others. This guide dives into H263, explaining its purpose, functionalities, and how it compares to similar standards. We'll also explore methods for converting H263 videos using user-friendly tools like HitPaw Video Converter.

Part 1: What is H263?

H263 is a video compression standard designed for low-bitrate communication. Developed by the ITU-T Video Coding Experts Group (VCEG), it was standardized in 1996. The primary goal of H263 was to enable efficient video transmission over limited bandwidth connections, making it ideal for early video conferencing applications.

H263 achieves compression by employing techniques like motion estimation and compensation. It breaks down video frames into smaller blocks and analyzes the differences between them. By focusing on these differences rather than the entire frame, H263 significantly reduces the amount of data required to transmit the video.

Part 2: What is the Difference Between H262, H263, and H264?

H263 belongs to a family of video coding standards denoted by "H.26x". Let's explore the key differences between H262, H263, and H264, three prominent members of this family:

  • H.262/MPEG-2: Developed earlier than H263, H.262 (also known as MPEG-2) was designed for higher bitrate applications like broadcast television and DVD storage. It offers better video quality compared to H263 but requires a larger bitrate for transmission.
  • H.263: As mentioned earlier, H263 excels in low-bitrate communication. It prioritizes efficient transmission over pristine video quality, making it suitable for video conferencing over limited bandwidth connections.
  • H.264/AVC: H.264, also known as Advanced Video Coding (AVC), is a significant advancement over H262 and H263. It offers superior video quality at lower bitrates compared to its predecessors. H.264 is widely used for various applications, including streaming services, Blu-ray discs, and video calls on modern devices.

Part 3: How to Convert H263 Videos

While H263 played a crucial role in early video communication, many modern devices and platforms may not natively support it. If you have H263 videos and need to convert them to a more widely compatible format, here are some methods: HitPaw Video Converter.
