The main difference between the H.265 and H.264 video compression technologies lies in the file size. The newer H.265 technology provides more efficient compression than its predecessor, allowing for smaller file sizes compared to those generated with the older H.264 format. This means that a video encoded using the H.265 codec will take up significantly less disk space than the same video encoded with H.264. This is especially important for users who need to store large files, such as 4K and 8K videos, on their hard drives or other storage drives.

What is H.265?

H.265, also known as High-Efficiency Video Codec (HEVC), is a video compression standard designed to reduce file size while maintaining video quality. This new codec offers up to 50% better compression than its predecessor H.264, allowing for smaller files and faster streaming speeds. It’s the compression standard of choice for 4K and 8K videos, providing sharp visuals with minimal file size. H.265 is also widely used by streaming services on the web, such as YouTube and Netflix.

Pros & Cons:

Pros:

• Smaller file sizes, allow for quicker streaming and download speeds.
• Support for 4K and 8K video formats.
• Improved compression compared to H.264, enabling high-quality visuals with smaller files.

Cons:

• High hardware requirements – requires higher processing power than H.264 to encode and decode videos.
• High licensing costs – the H.265 codec is encumbered by patent licenses, which can be expensive for businesses.
• Larger file sizes than other video formats such as VP9 and AV1.

What is H.264?

H.264, also known as AVC (Advanced Video Coding) or MPEG-4 Part 10, is a video compression standard developed in the early 2000s. It is the most widely used codec today and is used by major streaming services like YouTube and Netflix to compress video content. H.264 provides good quality at relatively low bit rates, although its compression efficiency can’t quite match that of newer standards such as H.265.

Pros & Cons:

Pros:

• Widely used and supported on most devices and browsers.
• Lower hardware requirements – encoding and decoding videos with H.264 is less CPU-intensive than H.265.
• Low licensing costs – the H.264 codec is unencumbered by patent licences, making it more affordable for businesses to use.

Cons:

• Lower compression efficiency compared to H.265 and other newer codecs, resulting in larger file sizes.
• Limited support for 4K and 8K video resolutions.
• Increasingly obsolete – most streaming services are transitioning away from H.264 in favour of more efficient standards like H.265 and VP9.

Key Difference:

1. H.265 provides better compression efficiency than H.264, allowing for smaller file sizes and faster streaming speeds.
2. H.265 has higher hardware requirements – it requires more processing power to encode and decode videos compared to H.264.
3. H.265 is encumbered by patent licenses, making it more expensive for businesses to use.
4. H.264 has lower hardware requirements and is unencumbered by patents, making it more affordable for businesses to use.
5. H.264 is becoming increasingly obsolete, with most streaming services switching to more efficient video codecs like H.265 and VP9.

Conclusion:

In conclusion, H.264 is the most widely used video compression standard today and provides good quality at relatively low bit rates. It also has lower hardware requirements compared to more efficient standards such as H.265 and VP9 and is unencumbered by patent licences, making it more affordable for businesses to use. However, its compression efficiency can’t quite match that of newer standards like H.265, resulting in larger file sizes. Ultimately, the best video codec to use will depend on your specific needs and requirements.

FAQs :

Q: What is the difference between H.265 and H.264?

A: The main difference between H.265 and H.264 lies in their compression efficiency. H.265 provides better compression than its predecessor, allowing for smaller file sizes compared to those generated with H.264, making it ideal for streaming 4K and 8K video content. However, H.265 requires more processing power to encode and decode videos compared to H.264, and it is encumbered by patent licences, making it more expensive for businesses to use.

Q: What video standards support H.265?

A: The majority of modern devices and browsers support the H.265 codec, including the latest versions of Windows 10, macOS Catalina, iOS 12, Android 9.0 and above, Chrome and Firefox. However, some legacy browsers or devices may not support H.265.

Q: Is H.265 better than VP9?

A: Both H.265 and VP9 are efficient video compression standards that offer good quality at relatively low bitrates. In terms of efficiency, VP9 can provide better compression than H.265 in certain cases, making it ideal for streaming services with limited bandwidth. However, VP9 is not widely supported on all devices and browsers like H.265 is, so it may not be suitable for all applications.

Q: What is the best video codec?

A: The answer to this question depends on your particular application and needs. If you are looking for a widely supported, cost-effective codec with good quality at relatively low bitrates, then H.264 is probably the best choice. On the other hand, if you need a more efficient codec that can provide good quality and small file sizes, then H.265 or VP9 may be a better option. Ultimately, the best codec for your project will depend on your specific requirements.
