I am new to this and hoping someone here can help me....I have a bunch of HD videos from my canon video camera that were on my old Dell. I recently switched to a MAC and put them all on a flash drive to transfer to my Mac. They all show up as .MTS files. I have been converting them to .mov files using iSkysoft. I used the HD setting, but I am still losing quality when I move them into iMovie. Is there anything I can do to retain the quality of these clips?
