I saw a video regarding PR-CS6 while viewing a clip in media browser, (clicked and playing, not hover scrub) you can mark In and Out points using "I" and "O" on the keyboard.
The orange active area would start and stop where selected. "I" and "O" are ignored when I try. The entire clip is active (all orange) regardless. "I" and "O" work fine if I load the clip in the source monitor.
Is that a setting somewhere?
You can't set In/Out points until a clip in imported, thus not in the Media Browser. What you saw were clips in a bin in Icon view.
Oh, I see.
