Video length is longer in Dorico than QuickTime?

I have a .mov video file that in quicktime player starts at 01:06:37:17 but when I import into Dorico, it starts at 01:06:36:04. So Dorico is playing more of the video than I knew I had. Even when I put the .mov into Final Cut Pro X, it shows me 01:06:37:17 as the initial frame. The frame rate for the video is 23.976 so it defaults to 23.98 in both Dorico and Final Cut Pro X. What is going on? How can I fix this?

Welcome to the forum, Johnathan. I’m not sure what might be going on there. Are you able to share the video file itself? What does MediaInfo tell you about the video file?
