Description
j2k is a free Photoshop plug-in for reading and writing the JPEG 2000 file format, the successor to JPEG.
Also known as JP2, JPEG 2000 uses wavelet compression as opposed to the DCT compression used in standard JPEG. The end result is better image quality in a smaller file. JP2 also includes mandatory metadata such as information about an image's color space.
Updated: May 2007 - From Brendan Bolles, Fnord: It has some pretty substantial improvements for AE. First of all, there is an expanded dialog with extra compression options, letting you set things like an arbitrary bit depth.
Also, it's now AE-native and supports Auto Proxy, meaning that when you're working at half-rez, j2k is able to read in only the pixels it needs which can really speed things up. This is a unique feature of JPEG 2000 wavelet compression (similar technology is also seen in Google Earth).
