Best way to add/ import intro animation?
So, I have a ten second animation (with an accompanying MP3 track) lined up, but aren't sure of the best way (or, indeed, any way) of adding these to Godot. If anyone could point me in the direction of a good tutorial for this- or give me a reasonable explanation, I'd be very grateful (all the tutorials I've found so far seem to involve sprite animations, or background animations created with Godot).
I'm pretty new to Godot- just at the stage of going through tutorials and making very basic programs, but am quite experienced in Gimp (which I used to create the animation) and, less so, Audacity- so I can have the animation as an MP4, AVI, or even the 70-odd individual JPG frames if this is easier. The native Godot animation formats do confuse me though- are they easy to convert to?
