 > 90000 / 25 = 3600.000000000 (exactly 3600) so there is no issue with 25
 fps streams, nor 30.000 fps (always 3000 units in tick), nor 24.000 fps
 (always 3750 units in tick), nor 29.970 fps (always 3003 units in tick).

 Sorry if this sounds stupid:
 Did you test this and it does indeed work as expected for 30fps and 24fps
 or are you assuming it would work?
