Hello,
I am viewing the previews of Action Essentials 2 from Video Copilot and the resolution seems very degraded, tons of artifacts also. This never happened before, and these are just pre-keyed clips for special effects, .mov files.
I have included a jpg of viewing the same clip in preview window of Bridge CS6 5.0.1.23, and in Quicktime 7.73. You can see in the image there is a huge difference. It renders fine in After Effects CS6, Premiere, and Photoshop.
I have purged the cache, restarted, checked for updates, etc.
I have updated nvidia drivers 306.97 and a 480 gtx EVGA vid card. Windows 7 64bit SP1, and i7-920.
This seems to have happened recently, as it used to preview in high quality. I checked video I did on my Nikon D800 and it appears to be fine, and uses a .MOV extension.
