What is H.264? 📺
H.264, also known as Advanced Video Coding (AVC), has been the go-to codec for many years. It's widely used for various applications, including streaming services, Blu-ray discs, and video conferencing. Here are some key aspects of H.264:
Key Features of H.264
- Compatibility: H.264 is compatible with most devices and platforms, making it a safe choice for video content delivery.
- Quality: Provides high-quality video at relatively low bitrates, suitable for streaming.
- Efficiency: While not the most efficient codec, it strikes a good balance between quality and file size.

What is H.265? 🎥
H.265, also known as High Efficiency Video Coding (HEVC), is the successor to H.264. It was developed to improve video quality at lower bitrates, making it ideal for 4K and higher resolutions. Let's explore some of its standout features:
Key Features of H.265
- Enhanced Compression: H.265 offers up to 50% more data compression than H.264 at the same level of video quality.
- Higher Resolution Support: Designed to support 4K and 8K resolutions, making it the preferred choice for high-definition content.
- Improved Streaming: Provides smoother streaming experiences, especially in bandwidth-constrained situations.
