Updated on Aug 1, 2023

When it comes to AV1 and HEVC, which format is better? If you have the same question, this article is for you. In today's AV1 vs HEVC comparison, we'll help you understand the key differences between AV1 and HEVC. Please read on.

Note: Not many devices support AV1 currently, you can use this professional video converter to convert AV1 to HEVC or other formats for wider compatibility:

HEVC (High Efficiency Video Coding) is the successor to AVC/H.264. What is AV1? AV1 is one of the newest video codecs and is a replacement for VP9. With a 34% higher compression ratio than VP9, AV1 is widely used for streaming video on the Internet and web browsers today. Many HTML5 videos and videos on popular video hosting sites are encoded using AV1 codec. In summary, we can say that AV1 provides a better compression ratio than HEVC. But that's not the only difference between AV1 and HEVC. I'll show you more comparisons of the most important aspects below. Scroll down now to find what you need to know about the two new video codecs.

AV1 VS HEVC – Exhaustive Difference Between AV1 and HEVC

1. Compression Ratio

HEVC provides a 34% (100 – 100/134) lower compression ratio than AV1. In other words, AV1 saves more bit rate and its coding efficiency can be about two-times higher than HEVC.

By the way, compression ratio determines the number of bit per second. A higher compression ratio can help to reduce video file size. That's why AV1 is easier for video streaming on the Internet.

2. Video Quality

Frame rate - FPS affects the smoothness of the video. The HEVC standard defines two tiers, one is used in very demanding applications, and the maximum frame rate can reach 300 FPS. The other is for normal applications, where the frame rate ranges from 15 to 60 FPS. The most commonly used FPS in AV1 encoded video is 25.

Resolution - HEVC supports resolutions up to 8192 x 4320, or 8K UHD. The maximum resolution supported by AV1 is 7680×4320.

3. File Size

To be honest, size is not an essential parameter of a codec. But to give you a better understanding of the differences between AV1 and HEVC, I will give you a brief introduction. Given the same video length, resolution, and frame rate, the file size is usually affected by the bit rate and compression ratio. Since AV1 has a better compression rate than HEVC, AV1 can compress the same quality video with less bit rate, so the video size is smaller. Therefore, we can conclude that AV1 file sizes are generally smaller than HEVC video files.

At last...

After learning the basic information of AV1 vs HEVC, I believe you have come to some conclusions. Share your opinion with your friends or me. That's all for now. Have a good day!
