Close Resolve, Save if you plan on finishing in Resolve. See this wiki to see how to save a Resolve Project DaVinci Resolve - How to Relink Offline Media from a Exported Project
*Put the Color Corrected files from Resolve into your AVID Project*. Open the exported Resolve files. There will be ONE .aaf file and several .mxf files. This example is short - most projects will have a lot more .mxf files.
AVID reads media from the Avid MediaFiles folder on the root level of the hard drive. The .mxf files exported from Davinci Resolve must be moved to this folder. See example below.
Copy or Move the .mxf files to the AVID MediaFiles>MXF>1 folder
After the files are moved to the Avid MediaFiles >MXF>1 folder on the hard drive open the AVID Project or make a new one.
Launch AVIDMediaComposer
Open your project
Make sure your project window is open >Tools >Project
Make a New Bin
Title the new bin "Color Corrected Footage"
Go to >File>Input>Import Media
Navigate to the .aaf file in the Resolve exported media folder and select it. Choose Open
You should see your clips load in the bin along with a timeline that resembles what was in Resolve that you rendered out.
They will be associated with the project name you gave in Resolve.
If they are not there, you may need to delete some data base files, or you saved them in the wrong spot. (you'll want to get the proctor for this)
