Premiere Pro/Sony A7S I/II Rolling Shutter Repair
 

Hello - can anyone tell me the correct percentage to use for Rolling Shutter Repair in Premiere Pro for both the Sony A7s and the Sony A7s II (and if not that, how I could calculate it)? I get the "try it until it works" method, but I'd like to be a bit more scientific than just what looks "about" correct - thanks!
