j2k overview
j2k is a free Photoshop and After Effects plug-in set 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.
The After Effects version has the ability to Auto Proxy, meaning that when working at half or quarter resolution, j2k will only need to read in a fraction of the file, resulting in dramatic speedups.
It also features:
- Alpha transparency
- Lossless compression mode
- 16-bit color
- Digital Cinema Support

Excellent, the plug in worked perfectly and adding a JP2 file in the install package to test shows a great attention to detail.
Good work
