The credits just fly around, often toward or away from the screen, leaving trails behind them. Not as popular with opening credits being used less often in film, but still shows up.
The effect is achieved by a specific form of slit-scan.
Remember, this is only about titles and credits doing this, not the effect of slit-scan by itself. Nor is it just an effect to make the titles seem to pop out. They have to actually move around.
This doesn't just have to be the opening or ending credits. Trailers could count as well.
Compare Vertigo Effect.
- Superman: The Movie did this for a teaser trailer, and after the positive reception, the opening credits were done in this style.

- 1958's Space Master X-7
- Doctor Who has played around with this since 1970. The title sequence used between 1970 and 1973 featured the serial's title flying towards the camera each episode, the slit-scan title sequence used between 1974 and 1980 used this for the title logo, the "space" title sequence used between 1980 and 1986 featured this effect for the Doctor's head and the show's logo, and the "galaxy" title sequence used between 1987 and 1989 featured the title logo flying towards, past, and away from the camera via CGI. From the 1996 telemovie onwards, the "towards the camera" variation of this trope would be standardized for the actor names and title logo in the opening credits.
- All versions of of 3-2-1 Contact's opening featured this to some extent, but Seasons 6 and 7 did it most prominently.
