Best practices for anamorphic proxies?

[Andrew Calvetti]

Hello friends,

Over the summer I've been hard at work on my first feature. It's a self-funded, shoestring project that I've been shooting on a Zcam s6 with a lomo foton anamorphic. I feel like Zcam's are still pretty fringe, but I've actually been loving the combo. 

I've been shooting in 5k 5:6 mode in prores 422, so the file sizes are pretty enormous by my standards (I usually edit 4k Amira or bmpcc4k prores). I'd like to edit the feature with proxies, but I'm not sure about the best way to ensure an easy relink on the other side.
I'm assuming I should make proxies of the files straight out of camera...before desqueezing 2x. Then I would desqueeze the proxies and just replace the footage after picture lock???

I'm editing in Premiere. Davinci is also an option if there's a compelling reason to switch!

Any advice before I dive in?

Thank you so much!

Andrew
