H.264 and H.265 Video Compression Format
Regardless of taking pictures on the cellphone or watching videos on YouTube and Netflix, all video data are compressed to smaller storage space to reach optimal transmission speed.
What are the current video compression technologies available in the market?

The Main Video Compression Technologies

H.264 and H.265 are the most common types of video compression standards. They generate the highest-quality images in the smallest video file possible.
H.265 improves the efficiencies, coding quality, and algorithm of the H.264 compression standard to produce a better compression performance.

They are Everywhere in Our Surroundings

Video compression technology is in various fields, such as video communications, TV programs, and online video streaming. For instance, YouTube, Netflix, and Apple TV+ are popular online video streaming platforms with many subscribers using H.264 and H.265 video compression standards. The powerful compression capability of H.265 is absolutely vital for the popularization of 4K high-quality images.
H.265 is also applied in surveillance security. For the dashcam, high-quality video files are compressed to smaller file sizes without sacrificing quality and significantly increase the life expectancy of the memory card.
In environment security, H.265 reduces the storage space usage on hard discs and makes remote monitoring, back, and other functions more efficient and smoother data transmitting.

H.264 and H.265 Comparison

H.264 is suitable for compressing 1080P videos. However, it may be slightly insufficient in videos with resolution in 4K or above. The H.265 video compression rate is twice as high as the H.264 under comparable video quality. This is why 4K video quality has been popularized on all major streaming platforms.
