Final Cut not including PNG in Export
I've re-exported this same file about six times and still the problem is persisting... I've included a PNG file in one of my compound clips that is visible in the Timeline Editor, but when I export my finished product, it isn't visible anywhere. I've confirmed the layering is correct (it isn't behind anything), and even more annoying - when I export just the compound clip the PNG is contained within, it's visible in that export, but not when exporting the whole movie.
For reference - I've included a screenshot of both the exported file and of the preview in FCP at approximately the same timestamp.
(Pierre should be RIGHT next to Elon - and yet he's turned invisible.)
And yet, there he is in the exported compound clip.
The Elon and Pierre PNGs are identical dimensions (700x700 pixels, 72x72 resolution), and as I mentioned, the layering of my clips is all right where it should be... I'm absolutely stumped.
