Plus, you can work with HDR10 files and get better support for color space metadata. What′s New in Adobe Premiere Pro CC 2017 Patched: Only those files will be delete according to the cache management preference. Version 11.1.2 only applies the preference to media cache files of a known type, like *.pek, *.ims and *.cfa.
