As Joe said, filters and extra fun stuff might need a different workflow, but the basic workflow would be…
On your deliver page in Resolve, select the Avid Round trip setting. This will give you a default Avid MXF media preset. You can change the actual codec to 220 if that is what you want to deliver, and that isn’t what the preset is set to.
from there, tell Resolve to output you files into the correct file path. (you can do this after the fact as well, but it is just as easy to do it now)
What ever you use for your Avid Media drive, point resolves output to that drive, and have it place the files into a folder called something like 777
(just use numbers)
Once your output is done, you will need to create a new aaf file for Avid to read. Go back to your edit page, with your timeline open, and do a Timeline export new AAF command. (Its in there somewhere) Take note of where you save this aaf to, as Resolve has also created an aaf as part of the round trip function, but that list is less reliable, especially since you didn’t start in Avid.
Launch Avid, and you should see a database being built for 777 (if your file structure was done correctly)
Create a project at the proper frame rate and size, create a bin, and import your aaf from the “export new aaf” step.
Hopefully at this point you have a timeline with all your media colored and in tact. Personally, at this point, i would then go rename 777 to be a folder named after the project. (Project A Color from Resolve)
If you used filters that were not being baked into your avid output, you may need to export a flattened quicktime movie into Avid, or you could still call up your Avid round trip workflow, but change the button up top that says individual clips to Single file. I think that will bake in any funky filters you might be using into the mxf media clip.
You could then use an aaf list to get Avid to break up that flattend quicktime, back into the edit points, so that your timeline still represents all the individual edits, but you will lose any ability to put handles into your Resolve output by doing it this way. The procedure to get Avid to automatically break up the edit points is another topic all together.
