I work with 5DmkII still frames which are very large, and I've learned here of the benefits working directly with the raw files (as opposed to separate processing with lightroom first). Problem is AE crawls as it chugs through each individual raw file. I am finally learning to use proxy's which should make my life much easier.
Because I use masks I assume my first step should be to stabilize the footage before adding the masks. Is this best done to the original raw because wouldn't the proxy be lower res?
To ease workflow I've been experimenting with first rendering out a ProRes4444 video from the raw files and then using that as my Master for stabilizing. I want 444 to keep best color data for PP. Would I be loosing anything by doing this?
As for using proxy's, I notice default is animation, is there any advantage to changing the proxy codec to ProRes for instance?
I do not have a defined delivery format and usually deliver ProRes. THANK YOU!
