Final Cut Pro cannot render Speed Ramps with Optical Flow

Title says it all. This is a shocking bug on multiple levels: Since you cannot render, you can neither preview it (since Final Cut Pro cannot render optical flow retiming in real time) nor export video containing it. I can’t say with certainty that this always happens – maybe there’s some hidden factor – since… Read more

How to enable Public folder (with Drop Box) File Sharing in macOS Sequoia or Tahoe

It’s insane that I have to write this, because it’s such an absurdly unintuitive and complicated process that I’m going to need this for myself, some few months from now, when I have to go through this kafkaesque dance all over again.
