When I load 2 4K videos, I can place each of them on its own video track. When I go to combine them in 3D, I get a Media Offline error. I tried even loading 2 videos from the same camera, so as to avoid any settings differences between 2 cameras, and I still get the error.
Things work when combining 2.7K videos. Even tried a 2K and 4K and it worked. Not 2 4Ks.
I have MS 14 Platinum.
Any ideas?
