Grey and white diagonal lines and no preview
In the image inserted you can see that the clip has grey and white diagonal lines and the preview pane is black. Why is this and how to I fix it? Notice the problem occurs straight after a section where the thin yellow line under the timeline ruler is green instead of yellow because I did some kind of "render" process that I followed instructions for.
I tried deleting the media files and media cache files manually but the problem persists.
