I'm new to HD workflow and am shooting with a Sony NEX-VG10. I have seen that importing this footage for editing, with iMovie and FCP preX, requires a transcode and the entire file structure, but I haven't been observing this as CS5 Premiere seems to work fine w/MTS files. Is this a poor assumption on my part or will my not saving the entire file structure of original MTS footage burn me later?? (I'm dragging just the MTS files to a folder, and using as needed.) Also, something new to me is the need to render the footage on the timeline in order to see it without a heavy moire effect on striped shirts. Once I render the timeline it goes away. I never had this with SD footage. Is this a by-product of a slow machine or am I doing something wrong?
