Export your XML from Final Cut Pro X and Create a New Project in DaVinci Resolve 12.5
One of the clips has a retiming effect applied, and a few of the clips have been color graded to improve the contrast and color balance. This step is only important if the person grading your program will be someone other than yourself and you feel the need to give him or her a timeline with a base grade to communicate your ideas. Grades that are sent to Resolve can be adjusted further, turned off, or removed altogether by the colorist.
You should also be aware that not every color adjustment will transfer to Resolve. Exposure, Saturation and Color changes in the Color Board will transfer, but secondary corrections using Color or Shape Masks will not. With Resolve’s powerful windows and curves, you probably want to create your secondary corrections in Resolve anyway.
To send your project to DaVinci Resolve, Press Command-2 to make the Timeline active, or just select the project in the Browser. Then, from the File menu choose > Export XML. Name and save the file to your hard drive.
