FCPX – Spatial Conform Modes

Often nowadays you will get camera media that has a higher resolution than your preferred project size in Final Cut Pro. My example footage has the size of a 5K RED Epic Frame (5120×2700 pixels  1:1.9 aspect ratio) and the project size is HD 1920×1080. Use the „Spatial Conform“ menu in the Inspector with one of the three modes to adjust to…

  • Fit (Default) the width of the frame.
  • Fill the height of the frame.
  • None the center crop of the frame.

I asked myself how FCP is actually behaving when you zoom into this kind of footage. For what I can see it does concatenate the scaling operations between the „Transformation“ and the „Spatial Conform“ settings.



The „Spatial Conform“ Default setting „Fit“ – Letterbox



The „Spatial Conform“ setting „Fill“ – Pillar-box



The „Spatial Conform“ setting „None“ – Center crop




The „Spatial Conform“ setting „None“ vs. „Fit“ – to archive the same framing you need to enter 400% and 1000% in the Transformation Scaling dialog.


There is no difference visible between the two ways you can zoom that close into a 5k frame. One may think this no big deal and should be always like this. But I know programs which couldn’t make this kind of operations in the past without any loss of image resolution.
