from 25 fps and 1080 to 50 fps and 720

Hi everyone!

My name is Daphne, i'm writing here for the first time, though I've been following you for some time now..
I'd like to convert a clip with the following properties:
1920 x1080
rate: 25 fps
H264
aspect ratio square
upper field dominance

in order to be able to work with 2 other clips with these properties:
1280x720
50 fps
Apple pro Res 422
aspect ratio square
field dominance: none

I tried to change the audio/video settings in the timeline, but to no avail: I always get a red render line and, after the rendering, the clip doesn't play properly.
I also tried to export the clip (it's 40 mins long) to compressor and change the frame rate and aspect ratio there, but it gives me an insane amount of processing time (like 7 hours!!).

I'm not sure what to do... and I'd greatly appreciate your help!
Thank you,
Daphne

That's about right for a 40-minute clip, especially if the source codec is h.264.
I'm thinking that doing it overnight is a good thing to do: let the computer do its work while you sleep. It doesn't care if it's awake.
