I can confirm the issue. I have Echo Fire for After Effects running on Tiger. An old job I was working on wanted a new version of a scene so I run the old project. Sometimes I like to switch off Echo Fire so I can do faster Ram previews. When I chose the video preview from within AE’s prefs the same footage I was previously seeing on my CRT monitor through Echo Fire went noticeably darker. I closed down AE and restarted in Panther. Opening the same project in my Panther partion with Quicktime 6.5 and 4.5 decklink drivers, the issue does not occur
