An AMV file is a video saved in the Actions Media Video file format, which is used by some Chinese portable media players. It contains a compressed, low-resolution (96x96 to 320x240 pixel) video.
The JPEG 2000 Code Stream (j2c) file format is a type of image file format that is part of the JPEG 2000 family of image standards. This format is specifically designed for encoding images in a highly efficient manner, allowing for both lossless (exact reproduction) and lossy (approximate) compression. The j2c format focuses on the core coding stream of JPEG 2000 images, representing the encoded image data without additional metadata or structure.
