BEST PRACTICES FOR VIDEO EDITING ON MAC MAC
The other type of color management used by Apple is targeted color management, which is a technique to apply color management during authoring on the Mac before delivering your content on iOS. It allows you to use any content and view it on any display, certainly on a desktop environment where you have many different display devices or other forms of output devices such as printers. Active color management is all about flexibility. OS X provides Active Color Management with ColorSync. This color management provides the formula to perform the color match, and that formula is applied to every pixel in the different frameworks (Core Image, Core Animation, ColorSync, Accelerate and various others) and applications. This color matching can be GPU accelerated when rendering to the display, or vectorized accelerated on the CPU when not rendering to the display (for example, when sending output to disk).
For each pixel a color match is performed from the source content's profile space to the destination space, possibly with an intermediate space or working space (requiring an additional color match) in between.
Active color management is a dynamic process, applied to every pixel in real time on every frame. Active and Targeted Color ManagementĪpple uses two different approaches to color management - one is active color management, which is provided in OS X. This color management offers the best color fidelity of the source media whether seen on a monitor, printed on a desktop printer or viewed on a mobile device. Your colors will be consistent over time, across media, and across different devices. Your colors are accurately translated from one device to another across your workflow. The colors the camera produces by taking a snapshot of a given scene will be reproduced faithfully on the display and in the finished printed product. This color management ensures the color fidelity of the original throughout the digital workflow - it delivers color that accurately represents the original. There are different methods to how this happens, and these will be covered in this document. OS X and iOS provide a robust, standards-based solution for color management that is designed to give you the best possible representation of your source media on all the various devices and environments you are working with. How can you make informed decisions during development so the final result matches your intentions across all the different configurations your customers may have? Accurate color that matches your expectations can help you generate more engaging visual products, and reduce development costs and timetables. Color makes a difference-often a dramatic difference-in our photographs, graphics, and other media.
