The Sony NXCAM exports files with an .mts file extension. When you plug the camera to the computer the camera’s hard drive will pop up in Premiere’s media browser. The files can be extracted this way. However, this leaves the problem that the files only exist on the camera and have not actually been transferred over and saved to the computer. This means that any editing would have to be done with the camera continuously attached to the computer. That’s not very effective. The best thing then is to make sure the files are saved on the computers hard drive or other easily accessible server.
If there’s a way to do that in Premiere I haven’t found it. And after my system crashed twice I don’t care to try again today. So for the purpose of being effective, I’m simply downloading the entire contents of the camera hard drive into the computer’s hard drive. I was told that the other files (the ones that are not the .mts video files) in the hard drive are necessary as well and not just there for decoration. So that’s why I’m dumping the whole thing into the computer.
