Grass Valley have released a version of EDIUS 8 which does not require QuickTime to be installed. This version will not load QuickTime files and various still image formats, so all they are doing is removing the requirement that QuickTime is installed when the program is installed. You can read their full information regarding this here: http://www.ediusworld.com/en/support/faq/cat121/edius_all_768.html
Only download and install this version if you need to run EDIUS and do not want to have QuickTime for Windows installed on your system. Our advice is to actually keep QuickTime for Windows installed and but just install QuickTime essentials as you lose a lot of functionality by removing QuickTime, and the threat caused by having QuickTime installed is not that great with just Essentials installed. You can download this version from the Grass Valley download site - http://www.grassvalley.com/support/downloads/products.
If you install this version and you have QuickTime for Windows installed you will have all the functionality you had before, so basically no change from the original version of EDIUS 8.2.
This version is phase 1 of Grass Valley's QuickTime plan. Phase 2 is that around June/July they will have a version which will load/export still images and QuickTime files (although possibly not ProRes QT files). Phase 3, in around September/October will be fully functional with no QuickTime for Windows needed.
Obviously these dates are approximate but at least we have a rough time-scale.
Although the above says things like "no ProRes support" you will still be able to load ProRes if you have QuickTime for Windows installed. However, the ultimate plan is to not need QuickTime for Windows at all.
