If you aren't using the DaVinci Resolve version of the Frame.io integration, we highly recommend you try it out and better improve your workflow process. It's a great way to easily have the full Frame.io experience imbedded within Resolve and helps easily collect your feedback and import them into your timeline.
If this isn't installed on your computer, you can still utilize properly importing your comments into Resolve as an EDL list just through the web app.
To do this from the Web App, double-click the clip with the comments you want to import and click the down arrow at the top of the Task List. This will present the different comment exporting options. Click on Download as Resolve EDL option to grab your Resolve EDL file.
To bring it in Resolve, right-click on the timeline file in the Media Pool, then click on Timelines > Import > Timelines Markers from EDL. Your feedback comments should now appear on the timeline tied to the exact frames in your video project!
