For example, a 24-bit uncompressed 4K video running at 60 frames has a bitrate of 11.9 Gb/s. Simply put, the bitrate of a video is defined as the number of bits the video needs to play for a second. Therefore, while selecting a compression algorithm, it's essential to look at the quality it delivers at a particular bitrate, but what is the bitrate of a video? However, you also need to consider that the quality it delivers decreases as you keep compressing the video. If you have a 4K video that is taking up a lot of space on your system and can't upload it to your favorite streaming platform, you might be looking for a video codec that offers the best compression ratio. Now that we understand how codecs work, we can determine which is the best out of AV1, HEVC, and VP9. Using this methodology, a video is broken down into a set of I Frames interleaved into P frames compressing the video further.ĪV1 vs. The P frames are then rendered using the information in the I frames and the change information for that particular frame. ![]() Here I frames are the ground truth and are used to create P frames. Hence, to reduce the video size, the compression algorithm divides the video frames into I and P frames (Predicted frames). All we need is a base picture that contains all the information and the data related to change when moving from one frame to the other. Therefore all the images are not needed to render the video. In such a case, all the frames in the video have a similar composition. For example, imagine a video with a person speaking against a fixed background. Videos are made up of several frames of images, and in most cases, all of these frames contain the same information. After that, the algorithm reduces the amount of color in the image based on compression levels. To perform chroma subsampling, the video compression algorithm converts the pixel information in RGB to brightness and color data. There is a 32bit as well as a 64bit application.Image credits: Janke at English Wikipedia/Wikimedia Commons Otherwise download and extract the content. Then you can download it from the Windows Store. ![]() Note: If you do not have the Windows application installer on your computer. This was mainly for Youtube streaming videos. ![]() They then moved onto the AV1 Codec as it was more resource intensive but with even better quality. Google developed this with the High Efficiency Video Coding ( HEVC/ H.265). There is also the CoreWavPack and the MPC-BE as well.
