Record the video and burn it in 60i. It will play in any Bluray player and on any HDTV in the world. And will have better movement fluidity.
50fps is needed only for TV studios that have licensing requirements. It is just an archaic remnant from analog TV times.
Anyway, if you still insist, see this thread that deals exactly with your problem, no need for another thread:

Hi Sonic, I have to disagree with you on this regarding 50p --> 60i (though the sentiment on old standards is correct).
The origin of the various frame rates like 50 and 60fps date back to the analogue broadcast and display equipment timing being driven by the power supply standards in each country (eg 50 or 60hz). Due to bandwidth limitations at the time the frames were then Interlaced to halve the stream size (another terrible idea in the modern age). As you mentioned in the "modern" world, we can use most any common media frame rate, be it Film (23.976/24fps), High Frame Rate Film (48fps), 50fps, 60fps, even stuff like 120fps.... as long as the player and display supports it.
The key with quality edited output is to keep the same frame rate for production as the source. As the OP's camera shoots in 50p you absolutely want to output in 50i or 50p (or a clean multiple/division). If you change the frame rate from say 50 to 60 you typically only have one of the following techniques, all of which are terrible:
- Keep all the Frames but Change the time they are displayed for (as used by Film to PAL distribution for DVD's Broadcast etc. The "PAL" versions are 4% quicker)
- Insert / Drop Frames but keep the run time the same (Telecline - will result in non smooth panning - commonly used by Film to NTSC)
- Interpolation of all the Frames (not commonly used or available in PD and results in weird artefacts)
So the key is:
1) Always edit and produce a finished file in the Same Frame rate for your archive (and hopefully playback).
2) For "distribution" you may have to change the output format to suit the end use device. Eg if the OP needed to send a DVD to the USA he will be better to send it as a NTSC DVD even though the quality is affected as the end users may not have a player or display that will play a native 50p stream
Thanks
