Not really.
If you are unsure about 25i, don’t shoot it.
You could shoot 25p, or 24p, 23.976 and 50p
All can be used to make good quality 25, although at some speed changes.
50p can be used to go to 25i, as well as (half frame, slowed down, added pulldown) to 29.97.
(And it makes for nice slomo if needed.)
But if the specs say 25i, and you don’t have problems with that, just shoot 25i or 50p.
