So, I’m currently having a very weird issue; when I play the movie through my bluray player, there’s a static phantom image of the opening crawl overlayed across the entire opening crawl. But when I play the same file on my laptop, there isn’t. I’ve checked and it doesn’t happen in the editing software either. I’ve got the same problem later in the film when some hazy blobs which look like mattes appear in a couple of scenes, which also aren’t there on the computer.

Edit: I’ve tried re-exporting from my editing software, and had the exact same problem.
