Converter MJ2 to JNG

MJ2 is a video category category format that contains the motion sequence of JPEG 2000 images. This video encoding system, which uses JPEG 2000 intraframe compression technology, was developed at the Fraunhofer Institute of Integrated Circuits (FIS). Since November 2001, it has existed as an international ISO / IEC standard. The codec is based on a discrete conversion. Compared to the MPEG family used in codecs, it performs encoding in two areas simultaneously. Both in spatial and in frequency. In this case, there is no need to split the images into blocks. Only intra-frame compression is used for each frame, and inter-frame coding is not applied. A distinctive feature of MJ2, that is, Motion JPEG 2000 Video Clip, is that it can be scaled. And not only in terms of frame size. And in quality, that is, in terms of video stream speed, too. The decomposition features are such that each frame can have its own copies, which are two times less vertically and horizontally. Since it is possible to compress without loss, it is possible to use this codec in the medical industry. After all, it is necessary for images to have high accuracy. Synchronization with video supports embedded audio.

JNG is a raster format. It has a close relationship with PNG. The JNG format uses exactly the same structure as PNG. It stores data in the main JPEG stream, is able to store the alpha channel stream in the form of PNG or JPEG, as well as information in the form of text. It also supports gamma and color correction. This image file format uses lossless compression similar to standard .JPEG files. The format was developed as a sub-format for .MNG objects. However, it is quite suitable as a separate raster image format. Some JNG files include an optional alpha channel for transparency. It does not support standard JPEG files. It is also possible to include auxiliary data sections, which may contain information about color space and comments. JNG is a format that is not very popular. Nevertheless, it has such a very good property as a large degree of lossy graphics compression. He also has an alpha channel. Color data is stored in JPEG format. For alpha, there is one of two storage options. It can be compressed using JPEG, like a grayscale picture. Or you can use the same as in PNG, lossless compression. The format is best suited to store texture atlases in mobile games. A good win for a mobile game.
