AOMedia Video 1 (AV1) is an open, non-commercial video compression format originally developed for use on the Internet. In fact, it was developed by Bell Labs, and the product is based on the VPX (VPizontal) video compression technology. The product was released in October of 1996. Since its release, many other video compression technologies have been developed.

This software has many additional capabilities than are related to the compression of video. It also allows the user to change the video format used, to adjust the quality of video, to insert various visual effects, and also to process text. The program also provides a decoder that can be used to decompress video.Youtube compression now adopt this codec.

AOMedia Video 1, like most other commercial products, employs two methods of compression: key schedule and adaptive scheduling. The key schedule method is similar to the conventional compression algorithm used in DVD. The first compression algorithm determines the rate at which the data is to be compressed. This is done by dividing the incoming data into blocks and then compress each block according to a pre-determined schedule. The blocks are compressed using a Dictionary/IDsS coding algorithm.

The second method is more complicated, but has the potential to save more bandwidth. The adaptive scheduling algorithm substitutes a key schedule with an availed schedule generated at run time from a control application. As is the case with the key schedule, the number of blocks to be compressed and their sizes are specified in the input file. Once the compression begins, the blocks are compressed using a Dictionary/IDsS coding algorithm. A final dictionary file containing all the compressed data is saved in the file. The size of the dictionary file is dependent on the availed av1 format.

The use of AV1 mode is recommended for low cost systems. This is because the codec is capable of encoding with only 14.2 Megapixel resolutions, as opposed to the much higher resolutions (such as that of HEVC) used by High Definition Networks (HDN). The reduced video compression ratio is due to the smaller file size and hence better video quality.

In order to compensate for the loss of better video compression quality, the AV1 mode also offers lower bitrates. However, it is worth pointing out that this comes at the cost of increased video portability. Since the file system is already used extensively for the Blu-ray video compression and encoding, there is no need to transfer the file from the host computer to the AV1 based decoder. A local network or the Internet can be used to accelerate the process of video compression. In other words, the network does not have to be configured differently and the local storage system can act as an interface between the AV1 decoder and the host computer.

The AV1 format is a freely available format and is therefore not copyrighted. It is licensed for public use under the GNU FDLv1.2 license, and the authors are free to make any modifications they see fit. The changes need do not alter the meaning of the data structures or the Av1 decoder itself, which means that a copy of the source code and binary data of the Av1 format is necessary. However, it should be noted that this still does not allow the application of some newer tools for decompressing AV1 data. These include QuickTime and XZipaligner.

The AV1 compression method has a major shortcoming in that it suffers a serious loss of quality when the data pattern is randomly generated. This is because the compression algorithm is based on a random access memory model and as such suffers from the same drawbacks that the file format itself does. This is one of the drawbacks of the file format that can result in significant file loss when the data has to be stored and compressed.
