Black thumbnails in CC Libraries
Hello all… we are working in a mixed Mac/Win10 environment, using the latest production releases of AfterEffects and Premiere Pro. Our primary graphic artist has created a set of animated glyphs (in .mov format) for video creators to use, and put them into a CC Library.
Our problem is with the library thumbnails. While the transparent background is shown correctly on Macs, it is a dark charcoal in Windows. For black graphics, this makes them effectively invisible. (see image below).
The graphic appears correctly once it is placed on a layer in AE or PP. How do we get the Library thumbnails to display correctly in Windows?
