Sony a6000 and iMovie

This is perhaps not a strict iMovie question, but a general video question. I got the Sony A6000, which has many video formats. The top is AVHCD 60p, but I already googled that 60p is not compatible with iMovie (in fact, it's not even imported to my Mac). I tried AVHCD 60i; that does import, but I get artifacts (look at the bucket in the picture). So, which video format should I use for best results for Apple? I would prefer a format that, for example, can be directly viewed on iPad without further editing (although eventually I will edit in iMovie).
