If you have got Sony HXR-NX70U NXCAM Compact Camcorder, you will find you can store content or back up important shots by copying footage directly from your camcorder to an external hard disk drive (sold separately) without using a computer. It can also access videos stored on an external hard drive for playback on HDTV, allowing you to utilize the camcorder's handy playback features.
The NX70U camcorder recorded video is AVCHD(.MTS or .M2TS) frmat, as we all know it is a not good editing format, in general, we have to make sure AVCHD files are directly from camcorder if we import the recordings to Mac softwares for playing and editing, like iMovie. Besides this, the AVCHD video with 1080p@60fps is not supported by almost NLE's. So, if you try ingesting HXR-NX70U clips to iMovie, you are likely to meet some incompatible problems, it menas you probably see anything in iMovie.
To help Sony HXR-NX70U users to avoid the issue, we suggest you to transcode the nonstandard 60p files to a comfortable format before transferring. You should know iMovie is designed to natively edit AIC .mov format, so we can transcode AVCHD to AIC, thus we can directly drag and drop the converted file to iMovie 8/9/11 for further editing.
