Ratings & Reviews

  • This app hasn’t received enough ratings or reviews to display an overview.

Imported LUTs now render accurately and match DaVinci Resolve and your monitor. When you import a .cube file, pick the input format it was built for (Apple Log, Apple Log 2, S-Log3, LogC3, V-Log, D-Log, Blackmagic). LUTs that previously had no effect now apply correctly. Plus performance and stability improvements.
