Yeah the camera shoots in either 50i or as the special option of 50p.
ClipWrap works well and rewraps the h.264 video in a Quicktime container. There is a ffmpeg script/app (Rewrap2M4V) floating around which does the same trick. ClipWrap however is a commercial product and therefore more capable. For instance, it can transcode directly into ProRes if you wish, which is an extra step in the Rewrap2M4V flow. If you go for the free workflow, you need to transcode into a workable format for FCP. Some use Toast, StreamClip etc. to accomplish that. Others use the VoltaicHD app, but I’m unsure if it can handle the 50p/60p versions, but I would bet it can.
