4K on a 1080p timeline

Coming from Premiere, when I woukld drop 4K footage on my 1080p timeline, I would manually resize (50%) all the clips. Then when I would crop in etc., the image would be great quality (as I'd be exporting 1080p). I noticed with FCP it resizes my 4K footage automatically (and I think even smaller jpg's etc are blown up to fit, may be wrong about that part) BUT when I crop in now, do I lose any image quality in my 4K footage? Would it be better to start with a 4K timeline? Looking for best practices.

You need to know about this setting called "Spatial Conform". You set this in the Inspector.

The default is "Fit". That is what makes your 4K clips automatically scale to er... fit.

The other two options are "Fill" and "None".


"None" means that 100% scale is your original. That is probably what you are accustomed to.


"Fit" and "Fill" are best understood with a still image (4:3) in a 16:9 project.

With "Fit", at 100% the image is shown so that all of the image fits inside the frame (in this case leaving empty space on the sides). With "Fill", 100% is what makes the image completely fill the frame (in this case cropping a bit on the top and bottom).


If you are going to export in 1080, the general advice is to make your project 1080.
