Sample text

The MPEG-2 compression is specifically designed for moving pictures such as video. It starts by performing a JPEG-type compression on selected key frames, and then shrinks the in-between frames by constructing a list of what the differences are between the key frames. 4 EXR OpenEXR, or EXR, is a floating-point image file format developed by Industrial Light & Magic (ILM) that is fast becoming an industry standard. It is very likely that you will encounter it early in your digital compositing career and more likely over time, so it behooves us to take a moment to look at it closely.

OpenEXR was released by ILM to the world as an open standard for free in 2003 in order to rapidly propagate it into the visual effects industry. It has worked. Most 3D animation and compositing programs now support EXR. It has even penetrated to the ubiquitous Adobe After Effects® and Adobe Photoshop®. 5 File Formats We cannot discuss every file format in the known universe since that would be an entire book on its own. What we have here instead is a mercifully brief description of several of the most common file formats that you are likely to encounter in your budding digital compositing career.

Two predominant lossless compression schemes are RLE and LZW. Run Length Encoding (RLE), which is almost always used for rendering CGI images; and, LempelZiv-Welch (LZW), which is important because it is available in a great many image file formats. Since these are lossless compression schemes, they reduce file size without any degradation of the image; in addition, they can also be used together. Use them freely on CGI and graphics knowing that they will not harm your pictures. Photographic images can use LZW, but there will be minimal compression.
