Edit your reels in Final Cut Pro
Export from Reduct
From the reel export menu, select Final Cut Pro X (xml 1.8 & srt).

Import into FCP
Open the .fcpxml file that you just downloaded. If you have Final Cut Pro installed, the file will automatically open within FCP.
💡Pro tip:
If you get a warning about edit frame boundaries, just hit OK.
You can now re-link to the original file in FCP. Under File, find Relink Files > and select Original Media…
In the popup window that appears, find the source file on your hard drive, and click Relink Files:

Edit
You now have a Final Cut timeline where your reel (+ captions!) have been imported, so you can fine-tune your reels using the tools Final Cut provides you.

Limitations
Note that the XML export does not include any title slides that might be in your reel.
