tags or notes can be generated and attached to individual clips, allowing the post-production team to review embedded notes and information from the production team. For productions that require the generation of proxy files, Adobe Prelude can integrate with Adobe Media Encoder to do the job. Adobe Media Encoder, as implied, is a versatile tool used in order to trans- code video and audio files from one file format to another. When productions are utilizing high-density file formats that are difficult for computers to play back and edit in real time, they often take advantage of what is called a "proxy" file. These are lower quality copies of the files that are more easily digestible for computer hardware and which make real-time playback and editing achievable even on lower end machines. The project is then edited in the non-linear editing program of the production's choice and then is swapped out with the high-quality master files so that the project master export can be created. Media Encoder is also capable of applying either custom or pre- packaged LUTs to footage during the transcode process, allowing for color accuracy and consistency throughout the post-production workflow. This is also quite useful in the creation of dallies, generating copies of files in a spe- cific format for specific use, exporting computer-generated content such as visual effects for editorial use, and any other task that involves rendering a piece of source con- tent into another file format. Once media has been ingested and (if necessary) transcoded, it can be for- warded directly into Adobe Premiere Pro—Adobe's flagship non-linear edit- ing program. On set, this is a useful tool that allows for 695 engineers to verify the viability of files, play back previously shot content for review, sync sound files to video files, and organize bins & string outs. Although Premiere comes with a plethora of plugins for generating visual effects, sound effects, color grading, and transitions that allow users to begin and end without ever leaving the application, the soft- ware also includes a variety of export options that allow for integration with third-party software. Users can export XML, OMF, AAF, and EDL files so that final color and sound can be completed in more popular applications such as DaVinci Resolve or Avid's Pro Tools. Both Adobe Premiere Pro and Adobe Media Encoder are exclusively 64-bit applications that take advantage of Adobe's Mercury Playback Engine—an audio/video decoding algorithm that takes advantage of multithreading processors (such as Intel's Core or AMD's Ryzen line of processors) and GPU acceleration on approved graphics processing units (such as Nvidia's GTX/RTX line or AMD's Radeon line of graphics cards). This allows both applications to take advantage of various pieces of computer hardware to perform specific tasks, effectively speeding up the process of rendering files. While multithread processing
