A custom overlay seems to let some pixels peek through. FCP X doesn’t maintain the overlay well when changing the window size; some pixel peek close and new vertical lines of the footage behind the overlay peek thogugh. See image below. Any thoughts with this folks? Am I missing something or are the numbers I am using wrong for the overlay?
Not sure what you mean. There’s no pixelation at all. I just notice that the overlay doesn’t fit properly and allows these lines of pixels to peek through at the top and bottom. Perhaps it’s just simple math and I’ve made a mistake. However when I have the (what I think is the properly formatted overlay) applied, it doesn’t sit cleanly over my video. As i resize the playback window sometimes it will be clean, but mostly it won’t.
So either I have the dimensions wrong, or something strange is happening inside FCP X.
Consequently the overlay that seems to work best is a 4096×1716 visible inside a 4096×2304 overlay. However I wouldn’t have chosen this since my footage is 4K/UHD.
