ADDED TO MY POST ABOVE:
If I'm right in my initial assumption, your solution might be, to Open your Nepal Source Video into the Album, via the empty Folder Icon (Top-right in Album " Select Video from another location"), navigating to it, via Windows Explorer & allowing Scene Detection to take place. Try that.
BTW - (And before anyone picks me up on it
), ignore the black bars in TimeLine Scenes, in my ScreenShot. That's 'cos The Source Video is 16:9 & I have my Project Preference set to 4:3.
Back to Marc P & Anyone-else? Since I won't be around until end of Nov.
Good luck
ADDED - Can't Edit my ScreenShot Post. If I do, the ScreenShot usually disappers. However I missed the fact that you've Opened your Project In S11 & not S12 (& presumably created in S11?)
. My suggested fix remains the same.
