Using iMovie to edit a Video_TS file
I am running iMovie 10.1.9 on an iMac running OS High Sierra 10.13.5. I haven't used iMovie since I abandoned my PowerPC a few years ago, and am not familiar with this version. Here's my question(s): Can I import a Video-TS file directly into iMovie, or do I need to convert it? If converting is necessary, what format will yield the least loss? What software should I use to convert?
