Part 1. H.264 vs. H.265

H.264, or Advanced Video Coding (AVC), is a widely used codec standard that can balance efficiency and quality. It became the standard for playing, recording, streaming, and distribution since it is compatible across platforms and devices. Even though H.264 is already outdated/old, it remains dominant due to its universal support and stability.

H.265, on the other hand, also called High Efficiency Video Coding (HEVC), is the better version of H.264. It can maintain the same output quality as H.264 while using about half of the bitrate, making it perfect for 4K and 8K content. The only drawback here is that its adoption is slower since it needs more powerful hardware and modern software for smoother playback and editing.

If you want to learn more about H.264 and H.265, you can check the table below.

• Achieves 50% bitrate reduction for the same quality
• Good
• Widely acceptable for HD content
Video Quality • Better
• Optimized for 4K/8K and HDR
Very high, supported on most devices and platforms Compatibility Limited, newer devices/software required

Processing Power • Higher
• Requires a more powerful CPU/GPU

Part 2. When to Convert H.265 to H.264

Are you wondering when you need to convert your H.264 to H.265? There are many reasons why and when you need to convert your files. To learn more about them, see the information below.

Device Compatibility

Some devices, such as mobile phones, smart TVs, and media players, especially the old ones, only support H.264. If you have an H.265 file, you might encounter a compatibility issue that causes a playback error. To solve the problem, it would be better to convert your H.265 to H.264.

Editing Software Support

Some video editors and tools struggle with H.265, making H.264 easier to work with. With that, if you want a smoother video editing process, always use the H.264 codecs for your videos.

Streaming Platform

H.264 is more ideal for streaming platforms since it can offer universal compatibility across virtually all devices and needs less processing power for smoother playback.
