Until now, most cameras used the H.264 codec, and thus the vast majority of CCTV systems are still operational but were installed years ago. The great majority of computers can encode video data using software and hardware-assisted versions of H.264 with minimal effort. The reason is that H.264 offers excellent compression with low-quality loss and does not place an encoding system under an undue strain. It allows for more significant areas of the previous frames, thus saving your storage space.įor a long time, and even now, H.264 has proved to be a superb compression method, and it is still the most extensively used codec. On the other hand, in H.264, they can only be 16 x 16. In this method, the spaces containing information from another frame can be divided into blocks of 4 x 4 to 64 x 64. CTU is the term for this procedure, abbreviation of Coding Tree Units. In H.265, you can break the data from the preceding frame's original pixels into several sizes to suit every scene better. A video encoded with H.265 would be 1-3 times smaller than the one encoded with H.264. So, it can be concluded that H.265 can provide a smaller file. Given that, H.265 uses a lower bitrate to transmit the same quality as H.264. For example, on HEVC vs H.264 comparison, if H.264 High Profile takes 512 Kbps to transmit a 720p 30fps image then, H.265 only needs 384 Kbps.įirst and foremost, you must understand that the size of a video file can be calculated by multiplying the bitrate by the length. H.265 can lower file size and bitrate so that it only occupies the necessary bandwidth, thanks to its high compression ratio. Here are some of the most critical factors you must consider before deciding between H.264 and H.265. HEVC video codecs use a PC's GPU's accelerated decoding power to deliver the requisite performance for little or no extra expense at all. H.265/HEVC can also support resolutions up to 80M pixels with 8K UHD included.Īs a result, H.265 improves the H.264 encoding efficiency of the video compression standards by providing the best quality content in the smallest video file. Mainly, it transmits videos in high quality at the same bitrate. Compared with H.264, this codec offers between 25% and 50% better content compression while maintaining the same level of video quality. The H.265 video compression standard is for the advanced times of the high-resolution video. The H.265 codec is also known as High-Efficiency Video Coding, abbreviated as HEVC. Also, this format supports 4K and up to 8K Ultra HD. H.264 is a compensation-based, block-oriented video compression standard with multiple tools and levels such as max resolutions and bitrates. Moreover, you can play videos in this codec practically on any device. It is trendy among streaming services that seek to give their customers the finest watching experience. The codec is a video compression industry standard that allows content creators and publishers to compress, record, and distribute online content (videos), particularly streams.ĪVC/H.264 is a standard that can provide high-quality videos at lower bitrates than previous standards. It is the first codec that comes to mind while talking about video compression. H.264 is also called MPEG-4 Part 10 and Advanced Video Coding (AVC). H.265 and how to choose the suitable one from them. This article will explain all the differences between H.264 vs. So selecting the suitable one is a must thing. If you want a high-definition or efficient video, you must convert your H.264 videos to H.265. The decision is based on their output requirements. However, there are many situations where people have to convert between these two formats. H.264 and H.265 are two unique video coding standards, but people often misconceive them as one. The codecs are crucial because all the output video aspects depend upon them. With the advancements in technology, codecs have also come a long way.
