I typically do a different workflow for this kind of thing.
First of i rarely worry about audio into Resolve. You said the sequence is going back to Avid, so i’m assuming you just want to color in Resolve, and do the rest of your finish in Avid. This is my workflow as well. I don’t need 14 tracks of audio in Resolve to do a color pass. Export a wave file from Avid of your offline mix, bring that into Resolve and edit it onto your timeline. Delete the rest of the audio from the resolve timeline.
ack in Avid, i don’t usually embed the media during the aaf creation. Take your sequence duplicate it and put it in a bin call to Resolve, and transcode it, with handles to a clean “1” folder in your Avid MediaFiles structure. (rename your current “1” folder to something else…”Project name offline edit media”
Once the transcode is done, move your “Project name offline edit media” folder up one layer, effectively hiding it from Avid.
Now, when you load the transcoded version of your sequence, you should see it online, and the original sequence offline. Does your newly transcoded sequence look correct? If any media is missing, look at that media and figure out what is different about it. This will tell you that all the media you need has been properly transcoded.
Now, export an aaf, but only with the linking options set…no media creation necessary.
Once that is done, open the newly created timeline that has the word exported next to it. Does it seem correct? This is essentially the same timeline that Resolve will be reading. There is no need to keep it in Avid, I usually delete it, but it is handy to check to make sure all the tracks that I wanted to come across are there.
Now rename your “1” folder “transcoded to Resolve”
Launch resolve, import your transcoded to Resolve folder into your media pool.
import your aaf, tell Resolve not to automatically load media…it will ask you where the media is, point it to the media you just brought in.
With any luck you will get a timeline, where everything is online.
Delete the audio tracks, add in your wave file, and color the show.
When you export back using the Avid delivery preset, the list that is automatically created will still include your original audio tracks. Resolve doesn’t create a list with any changes that you’ve done to the timeline, unless you specifically request it.
This is the workflow I’ve been using successfully for years.
When you are ready to send the final edit changes from resolve to Avid, there are a couple of things you might want to consider before you commence, but that is another topic.
