Part 1. What is H.264 and H.265

H.264, also recognized as Advanced Video Coding (AVC), stands as a widely embraced video compression standard co-developed by the International Telecommunication Union (ITU) and the Moving Picture Experts Group (MPEG). Initially introduced in 2003, H.264 efficiently compresses video data through the application of block-based compression, variable block size motion compensation, and entropy coding. It achieves a harmonious equilibrium between video quality and compression efficiency, rendering it suitable for diverse applications such as video streaming, video conferencing, digital television, and Blu-ray discs. H.264 has emerged as a standard across various devices and platforms, boasting extensive compatibility and widespread support, particularly in scenarios where considerations include bandwidth and storage constraints.

H.265, on the other hand, alternatively known as High Efficiency Video Coding (HEVC), is also a video compression standard by the same developer as H.264. Released in 2013, H.265 is strategically crafted to substantially enhance video compression efficiency when juxtaposed with its forerunner, H.264. This standard incorporates advanced coding techniques, featuring larger block sizes, refined motion compensation, and improved entropy coding, thereby enabling it to deliver superior video quality at reduced bit rates. H.265 is notably well-suited for high-resolution content, including 4K and 8K video, earning it popularity in applications like video streaming, broadcasting, and the storage of high-quality video content where bandwidth efficiency assumes paramount importance.

Part 2. H.265 vs H.264

Before diving into the comparison, let's summarize the differences between H.264 and H.265 using a table:

Now, let's explore specific scenarios:

H.265 (HEVC) vs H.264 (AVC): File Size

◆ H.264: Generally, produces larger file sizes compared to H.265 due to less efficient compression algorithms.

◆ H.265: Offers better compression efficiency, resulting in smaller file sizes for the same level of video quality.

H.265 (HEVC) vs H.264 (AVC): Quality

◆ H.264: Provides good video quality and is widely used for various applications.

◆ H.265: Generally, offers better video quality at the same bit rate as H.264, making it more efficient in terms of compression. You can enhance video quality by converting H.264 to H.265.

H.265 (HEVC) vs H.264 (AVC): Compression Methods

◆ H.264: Uses older compression methods, which are less efficient compared to H.265.

◆ H.265: Utilizes more advanced compression methods, allowing for better compression without sacrificing quality.

H.265 (HEVC) vs H.264 (AVC): Compatibility

◆ H.264: Widely supported by most devices and software, making it highly compatible.

◆ H.265: Although gaining support, not all devices and platforms fully support H.265, which could lead to compatibility issues in some cases.

H.265 (HEVC) vs H.264 (AVC): Usage

◆ H.264: Commonly used for video streaming, video conferencing, Blu-ray discs, and various other applications.

◆ H.265: Becoming increasingly popular for high-quality video streaming, 4K and 8K content, and applications where bandwidth and storage efficiency are critical.

H.265 (HEVC) vs H.264 (AVC): Streaming

◆ YouTube Uploading: Both H.264 and H.265 are supported by YouTube. H.264 is more universally supported, but H.265 can be beneficial for faster uploads and reduced storage costs.

◆ Online Streaming: H.264 is still widely used for online streaming due to its broad compatibility. However, H.265 is gaining traction, especially for high-resolution streaming where bandwidth efficiency is crucial.

◆ Video Content Creation: H.265 might be preferred during the content creation phase if storage efficiency is a priority. However, compatibility with editing software and hardware should be considered.

The above are the differences between H.264 and H.265. You can find a better one based on your different purposes.
