how to set the fps?

[matteoraggi]

I exported .png 250 frames at 25 fps from after effects and then importing them with the frame delay per second 10 it is too much slo and if I chaneg it to 25 it is too much quick. How to set the fps?
what means exactly "all frames delay" and "selected frames delay"?

All frames delay means how long it takes for the next frame to appear.

Found this documentation online:
This will be the frame rate of the animated image, written in fractions of a second.

The default is 1/10 of a second, written as 1 10 (0.1 seconds = 100 miliseconds)

other framerates:
10 fps = 100ms -> 100/1000
15 fps = 60ms -> 60/1000
24 fps = 40ms -> 40/1000
30 fps = 33ms -> 33/1000

Yep verified and as per above more accurate calcs:

8 fps = 1000ms/8 = 125ms -> 125/1000
12 fps = 1000ms/12 = 83ms -> 83/1000
15 fps = 1000ms/15 = 66ms -> 66/1000
25 fps = 1000ms/25 = 40ms -> 40/1000
30 fps = 1000ms/30 = 33ms -> 33/1000
60 fps = 1000ms/60 = 16ms -> 16/1000

No matter what fraction I use from the table above the speed stays the same. I'm trying to mimic the speed of a GIF with .03 Seconds (30 Milliseconds) delay between frames and I just can't get there with APNG. Can anyone help me achieve this?
