I've been searching around for a solution to this and found many references to gamma shift bugs in various Apple software. Just totally confused by how to fix this!
I edited a short sequence in FCP 7, exported it and brought it into Motion 5 for adding a few titles and effects. After getting everything just how I want it, I exported from Motion 5 (I've tried exporting in a variety of formats) but the resulting video has much darker colours. Most noticeable are shades of yellow that were fairly pale in my Motion project, which turn out quite dark.
I would like to preserve the colours I chose in Motion - is this even possible? Is this a problem with using ProRes?
You're mixing FCP 7 and Motion 5. How are you viewing the output? QT 7 or QTX player? QT 7 and FCP 7 generally had a pretty incorrect representation of the video. For example if I watch on a broadcast monitor, QTX, Motion 5, and QT X more closely match than QT7 and FCP 7. Ever notice in the past how videos on the web looked darker on PCs?
Anyway it's been years. I remember QT7 had some preferences about gamma settings that affected how things were displayed. Might want to play with that.
