Manage media intelligence metadata

The Transcription options in the Media Analysis & Transcription section of Premiere preferences has additional settings to manage the analysis.

Premiere caches the results of analysis so that footage used in different projects or by different users doesn’t have to be analyzed again. You can choose to store the analysis metadata in the way that works best for you.

• In the Media Cache: Selected by default. Cache your analysis results in the Media Cache location set in Preferences > Media Cache. When you import a clip into a new project, Premiere will skip analysis if a cache already exists for that clip. The Media Cache is local to each user, so the analysis can’t be reused on other computers.
• Next to the media as a sidecar file: Premiere will cache the results of the analysis as sidecar files next to each analyzed or transcribed clip using a file with the extension .prmi. You can share media with sidecar files to different computers, and Premiere will use the sidecar file to avoid having to reanalyze the footage. This is the recommended preference when working in a Production. 
• Do not cache: The analysis results are saved directly into the project data or the project index. If the same clip is imported to another project or on another computer, the analysis must be run again.
