1230 Appendix C Working with Final Cut Pro
Using Float Precision with Motion Content in Final Cut Pro
When embedding Motion content in Final Cut Pro, you can take advantage of the
rendering benefits of Motion’s 16- or 32-bit float rendering modes. To do this, go to
your the Video Processing tab of Sequence Preferences in Final Cut Pro and enable
“Render all YUV material in high-precision YUV.” Once this is set, Final Cut Pro forces
Motion elements in the sequence to render in 32-bit mode.
