I had a chance to run through this yesterday. There does seem to be a bit of a disconnect going back to Avid, but it is a pretty simple fix.
It is possible not choosing “create unique filename” would help with all of this, but that is not possible in many cases. If you are using 2 different sections from the same shot, Resolve will simple overwrite the first instance with any later instances, so (for my money) you usually have to have unique names.
Here is a workflow that should work.
Note, I find this easier to do if all my original Avid media is offline. Lets me know immediately if I’ve missed a clip or not, so I usually move that projects media out of the mxf/whatever folder- up a level so Avid can’t see it.
Render out of Resolve to your ‘ClientName from Resolve” folder
Move this folder into your Avid MediaFiles/mxf folder
Rename this folder 888 (something obvious-numbers only)
Launch Avid
open your bin with your edit- everything is offline if you moved you media like I suggested earlier.
Duplicate your sequence and move it into a new bin called “final from resolve
Create another new bin called media from resolve.
in explorer or finder, open your 888 folder. Avid should have built a database for it upon launch. Drag that data base (MDB file) into your bin labeled Media From Resolve.
That bin is now populated with all your colour corrected media.
Select all those clips
Go to your Final from Resolve bin and select that sequence.
(Note, you can have items in multible bins selected at the same time)
Right click on the sequence and select relink.
in the relink options, (doing this from memory) choose relink to all selected clips in open bins.
I usually turn off match case sensitivity and turn on ignore extension.
I also usually turn off create new sequence at the bottom.
Hit OK, your timeline should now be online with the color corrected material.
If you’ve gone and changed 1 or two shots in resolve and rerendered, and then moved and overwritten clips in your 888 bin, Yes, those clips may be offline.
Open your Media From Resolve bin, select all and press the delete button. Tell avid to delete the master clips, but NOT the associated media. This will basically delete the clips from the bin, but not the 888 folder. Then re drag the database file into the bin, and relink.
Everything should be online again, including your tweaked shots.
