#opening title sequence

Both Saraqael and her earthly wheelchair completely disappear for a frame!

Shortly before they do, there's a black shape that flashes twice in front, as if to grab attention and count us in. One, two, pause for a beat and then Saraqael blinks - or, because this scene is in The Windmill Theatre, fails to miracle herself away, because of a miracle-blocker? (Except that this only happens in the opening title sequence of the third episode, not in all of them) - on three!

Here is a second attempt at the gif, this time even slower, with extra delay during the frames with glitches and on either side:

It kind of looks like the black outfit worn by the character behind Saraqael is flashing to the foreground for two frames - for both the first and second time this occurs - and most of Saraqael's earthly wheelchair is disappearing at the same time. Is there a little green screen popping through as well?

The first flicker appears for the last two frames of the animated text, "based on the novel by Terry Pratchett and Neil Gaiman" and then disappears with it, as if this animation layer is what affected the layers underneath. Could it possibly be to do with rendering, lag, exporting and whatnot? I really have no idea. Still...

After all that work, layering lots of elements and tiny videos together, to be simply undone like that? Yeah, nah.
