Given some available footage at say 50p, can Premiere make use of all those frames in the logical way to render "25fps interlaced" meaning 50 fields per second, even and odd, by taking alternating fields from alternating frames of the 50p?
I see from http://library.creativecow.net/articles/solorio_marco/interlacing_progressive_footage.php that After Effects does that exact thing.
But can Premiere CS6 do the same? Like if a 50p clip is placed on timeline of a "25fps-interlaced" Sequence?
I don't know the internal workings of how PP would make the conversion, whether it takes one field from each frame, or drops every other frame and takes both fields from the same frame. Certainly the former would make more sense.
Premiere is pretty smart about such matters. You should have no issues.
