Boris RED can read user marks applied to either the Media 100 Program or the individual clips (you did know you could apply marks to clips in the Edit Suite, right? ;-)
When you get into Boris RED...
- Go to the "Window" menu and choose "Show User Marks Window"
- In the "User Marks" window, click on "Import Host Marks"
While your messing around with this sort of thing, you may also want to choose "Show Timecode Palette" from Boris RED's "Window" menu and then choose "Host Timecode". This sets up RED to use the actual timecode numbers from your timeline.
