Installed Magic YUV - Use Powerdirector 365 - Need answers!

Hi folks,

On the Powerdirector 365 community Forum it was suggested I use this codec for my Powerdirector 365 worklflow, I have a very powerful machine but using Picelan plugins makes the previews over those transitions slow.  I was told this codec would change things.

I have installed the Ultimate Demo, is there anything else I need to do in order for PD365 to be able to smooth out the workflow using this codec or will it simply work because the codec is now installed?

Sorry for the noob questions!
