If you scroll down, I posted a few times. I went back to my old projects that were working just fine before the upgrade, and I just clicked on the video wall replicator in the video timeline and BOOM, it crashes. I have many projects that are all similar using HD video. It used to work all the time. Now it NEVER works.
Apple sure knows how to make software more unstable with each upgraded.
Anyone have suggestions for other Mac video editing software. I'm thinking of leaving FCPX. Which is the best out there from a standpoint of features and ease of use. Assume expense is not an issue.
