H.264, also known as AVC (Advanced Video Coding), is one of the most commonly used video codecs today. It became the industry standard for video streaming, Blu-ray, and broadcasting due to its balance of quality and compression.
Its wide compatibility across devices and platforms makes it the go-to choice for general use, especially where decoding performance matters more than file size.
H.265, also referred to as HEVC (High-Efficiency Video Coding), is the successor to H.264. It offers significantly improved compression, which means it can provide higher quality video at the same bitrate—or the same quality at a lower bitrate.
H.265 is especially useful for 4K or 8K content, where bandwidth savings are crucial. However, it requires more powerful hardware for decoding and is not as widely supported on older devices.
The primary advantage of H.265 is its superior compression efficiency. Compared to H.264, it can reduce file sizes by up to 50% while maintaining similar quality. This makes it ideal for high-resolution streaming and saving storage space.
However, this improvement comes at the cost of increased computational requirements for encoding and playback, making it less optimal for low-powered devices.
H.264 has near-universal support. It works seamlessly with most browsers, media players, and hardware. H.265 is supported by newer devices and platforms but may require additional codecs or plugins on older systems.
When choosing between them, compatibility often becomes the deciding factor unless you are targeting newer systems or aiming for optimal storage efficiency.
Use H.264 when you need broad compatibility across devices and don't require the highest compression. It’s ideal for web streaming, conferencing, and mobile playback.
Choose H.265 when dealing with 4K/8K content or large video libraries where storage and bandwidth are limited. It's perfect for premium streaming platforms and video archiving.
