Overlaying graphics at a different frame-rate

[VideoPlayout11]

I am outputting video from a software called OnTheAirVideo by Softron. Video is being directly outputted from a Black Magic UltraStudio Mini Monitor to a HDTV running at 25fps. Now I need to run graphics over the video, and wanting to overly at a different frame-rate, a much higher frame-rate for a smoother result (50fps). What will I need to achieve this? Or is this just plain ridiculous I know its best to keep all frame-rates the same, but 25fps interlaced is not the best considering I am working in different resolutions.


If this cant be done, how can I convert all my SD clips to 50fps from 25fps without the cuts fades or lighting change messing up for mac.


Thanks for your help

And this is not any video streaming.
