RAW to Pro Res how much am I losing?

I have RAW 4.6k dng footage. I want to edit in Premiere and finish coloring in Davinci. Since I'm using a lot of keyed changes to zoom, position, opacity, etc. would I be losing a ton of information if I convert the RAW files into ProRes 4444xq files?

Of course you will be losing lots of data, but data bits are meaningless in the video world if your final product is being displayed on the web, or on HD TVs, or over highly compressed satellite TV, etc.

So, where is your final product headed? Without that info no one can even begin to answer your question with any degree of precision that will be helpful to you.

It's a short film that will go to festivals and probably end up online at some point. It's mostly shot in 4K and final output to HD

you'll lose a few stops latittude. but if everything is exposed fine, there's nothing to worry about.

Can you make proxies to edit with and then enable the RAW once you're ready for color grading/finishing?

i'm inferring that he is exporting for other tools like AE. even so, a 32bit EXR can hold the RAW latitude if necessary. but yes, I agree that proxies are the best way to go. dynamic link might be a little too cumbersome.

I guess the problem is this. I have a LOT of speed changes and I'm using Twixtor in Premiere in addition to zooms, position and opacity changes. The Zoom position stuff will translate to DaVinci but the Twixtor stuff isn't compatible so then would the BEST thing to do, is export the RAW using Davinci to a high res file type, make the twixtor speed changes in Premiere then export again to the same high res format then bring it all into Davinci?

If that makes sense, what settings for an high res file format would you suggest? Pro Res 4444xq?
