import with activated animation technique which disabled, you know the correct distance please?

As are many frames, I would be sure not to repeat all the hard work again.

Please tell me what is the correct distance (seconds) to import PNG animation with the technique enabled - disabled?

00: 00,000 -> 00: 00.100

or

00: 00,000 -> 00: 00.250

My animation exported to PNG from after effects, has a speed of 23.976 frames

Thank you.
