Today Adobe released another update for Adobe Premiere Pro. This update contains mainly bug fixes and improvements. It should be pretty safe to install this update. Adobe actually states this is a Critical Update and highly recommends installing this update.
The reason why this is a Critical Update involves a feature introduced in 11.1 called: Media Cache Management. This feature has already been updated in version 11.1.1 but needed another update. Version 11.1.1 restricted cache management preference to be applied to files within the Media Cache folder structure. Now with version 11.1.2 will only apply the preference to media cache files of a known file type (such as *.pek, *.ims and *.cfa). Only those files will be deleted according to the cache management preference. The folders they are in will remain on the system. Additionally, the Media Cache management will be off by default.
There is quite a list of things that have been fixed and improved in this critical update. Think about: Stability and performance improvements, formats and file support, fixes that apply to effects and general improvements. See the link below if you would like to read the entire list.
Our latest product Impact Motion Tween will work significantly better with the latest update. After updating Premiere to version 11.2.1 Image positions are no longer shifting during scrub and playback with 1/2 or 1/4 playback resolutions. Explore the power of Impact Motion Tween.
