I've been noticing an issue in MC 7.0.3, when bringing in a sequence created with an earlier version of MC (6.5.4.1 or earlier) clips in the sequnce that have motion effects on them will lose the motion effect. A generic plug-in icon will remain on the effect but if you try to open it Avid will state that the effect is unknown and will not be able to tell you what it used to be. This doesn't happen 100% of the time. I'm not sure what causes it to happen when it does. Also, taking one of these "updated" sequence back to a previous version of Avid doesn't restore the missing Motion Effect, it stays "Unknown."
Has anyone else noticed this? This one thing is about all that is keeping me from starting a v7 migration.
