"That clip is not long enough."
I was making a trailer and had finished exporting.
Upon reviewing the export, I noticed a few flashes of placeholder images, but nothing was showing in the story board.
There were items missing in the shot list.
Having tried to drag items into the them, but I got "That clip is not long enough.", even though it had previously allowed images.
I quite iMovie and relaunched it.
Now half my story board shows place holder images, however if you preview them, they still show the original clip.
However, I can no longer drag anything into iMovie, as it says "That clip is not long enough.". These are slows between 0.3s and 2.0s, which video ranging from 1s to 1m.
All are being rejected.
Whilst I was building this project, I was dragging from Finder and after a while, iMovie kept getting stuck and moving the previously dragged asset into where I was dragging the new item.
