I have been using 10.6.8 with FCP 7.03 while on a project. every so often tcp will crash unpredictably. after having a major hardware issue, I upgraded to Lion and before applying both the 7.03 ProApp patch from apple, and the combined 10.7.5 update, the clips were playing fine on timeline, canvas and viewer. After upgrading them both to 7.03 and combined update 10.7.5, most of the clips became "corrupt". The 25fps clips will display only green on FCP canvas and viewer, and will flicker from other clips. This will ultimately cause the application to crash and cannot work like that.
This issue has been an issue since 10.6.8, but worsened with Lion or even mountain lion.
Before I loose all of my hair from pulling it, can someone be kind to shed some light on this?
